How To Fix [SOLVED] A disk read error occured...

TIP: You should click here to fix Windows errors and optimize system speed.

A mistake or inaccuracy, an error is caused about by committing miscalculations on the things that you do. It is a state of having a wrong judgement or conception in your conduct that allows catastrophic things to happen. In machines, error is a way to measure the difference between the observed value or the computed value of an event against its real value.

It is a deviation from correctness and accuracy. When errors occur, machines crash, computers freeze and softwares stop working. Errors are mostly unintentional events to happen. Most of the time, errors are a result of poor management and preparation.

From the Forums

A user in the forum details it further:

The files, in ISO format, will need to be burned to a CD using a program that can burn CD image files. First backup anything important. And what can i do to try to fix it ? Sounds like a hard drive getting ready to fail or it may possibly have bad sectors that are causing the error.

My question now is what could cause this error ? After leaving it for a little while and turning it back on or restarting the pc a couple of times i get the launch startup repair option which, after it finishes the PC boots normally. In most cases i get the "A disk read error occured" message and windows won't boot.

Is it software or hardware related ? After your data is backed up run a diagnostics program fro whoever makes the drive. In order to test the hard drive you can run one of the diagnostic programs below. If you don't know use any program and it will tell you. 640GB is most likely a western digital drive.

Ok here's my problem, sometimes after random periods of time my pc either freezes or i get a BSOD after which i have to restart it.

What causes [SOLVED] A disk read error occured...

If you received this error on your PC, it means that there is a malfunction in your system. Common causes are incorrect or unsuccessful installation or removal of software that could leave invalid entries in the Windows registry, the effects of a virus or malware attack, an incorrect system shutdown due to a power failure, or another factor in which a person with little technical knowledge accidentally deletes the required A system file or registry entry, as well as several other reasons. The immediate cause of "[SOLVED] A disk read error occured..." is a failure when one of its normal operations is properly started by a system or application component.

A disk read error occured

While trying to reformat my hard drive with the system startup disk it stopped before it was complete. its like there is no OS. When you do this is comes up to the boot menu which gives you 3 choices: hard drive, cd rom, or lan. None of these will let you start the system.

Now when you try to turn the system on it says 'a disk read error occured, press ctrl+alt+del to reststart'. What can I do to load the OS using my startup disk?. Didn't you format? (even half done format, means the OS is gone)

You need the Windows startup disc to remove the partition and re-install Windows (obviously you didn't need to save any data)

Just use a Windows CD

Disk Read Error Occured

I think that my hard drive may be knackered but do not know. It is 80gb divided up into 3 - c drive, back up (E) and Recover (F)

Any help greatly appreciated

Try here

Can someone please tell me how to start up in safe mode or alternative. I am running XP home on a P4.

It would not reboot though, it got onto the 2nd page of booting and then gave the error messege "A disk read error occured"

I have got into command prompt and typed DIR at the c prompt and all it shows is RECOVER.

A read disk error occured

This thread is now closed. See here
One thread per issue is sufficient!

I was wondering if anyone has had this problem, or knows how to fix this problem. So then i took it apart checked the wires to see if they were loose, still same thing. I finally got it together, and its been working for weeks, no problems. So i then tried to Do a system recovey/restore, i set it up so it reads the cd rom first, and i put my Win XP cd in there.

Ive tried several times, and still no change. Then suddenly the other day i went to restart it, as its restarting it says "A Disk Read Error Occured: im confused, turn it off, and turn it back on to see if itll work.

Ok, ive had nothing but problems with this new comp i built. Well it goes to a black screen, and the cd rom makes sounds like its tryign to load up, but instead it just sits at a black screen goign no where.

Disk Error Read Occured

When I check the BIOS, it recognizes the SATA hard drive as 500gb, and everything seems great, but I can't even boot up from the Vista CD, I get the same message. The weird thing is that everything worked great the night before, but I had recorded two large HD episodes for a total of 4 hours. When I reset it, it had the message of "disk error read occurred".

I only say this because I saw some threads about going over 127gb making your Motherboard unable to boot from the HD. I wonder if the BIOS was not updated to handle the increase in GB capacity from the shows. I am planning on installing a floppy drive today to update the BIOS, and if that does not work, I will pop in a spare hard drive to run some updates on the BIOS to see if that would work.

So I know this can be one of many problems, but I tried to start up the HTPC yesterday, and it would not awake from sleep.

However, if I disconnect the hard drive, I am able to boot up the Vista CD, but of course, now I have no hard drive to work with. Am I heading in the right direction thinking it is either the BIOS update or a bad hard drive?

A disk read error has occured

A chkdsk should at MAX only run about 45 minutes. Best bet is to go on ebay, find a 2.5" hard drive, and replace it, run your recovery disks and take it from there....sorry.

I've tried rebooting, removing the HDD and reinstalling it, I tried fixboot in Recovery console using my XP Pro setup disk, and finally have tried chkdsk /r using recovery. What probably happend is that when you slammed the lid, it might have scratched the surface platters of your hard drive, causing those parts to be unaccessable.

My system will not boot. Dumb move! I was having problems w' Yahoo and Outlook and after deleting several important messages I slammed my lid closed on the laptop. I did some Googling and was led to believe either the MBR or HDD is damaged.

BTW, this is an Acer 5670 laptop runnning SP3 on a 100GB HDD. Upon opening the lid and taking the system out of Standby, I received a fatal error 0x00000006 BSOD message, then upon reboot "a disk read error has occured" message. Any help would be greatly appreciated.

chkdsk is still running after 10+ hours and appears to have stalled out 5 hours ago at 61% complete. I rebooted between each step and so far get the same results, disk error. What these do is if there is any abrupt virbation or shock, it quickly shoots the actuator arms in the hard drive to the very end as to not damage the disk itself. The only computers with "Smart Drives" are toshiba laptops. A disk read error occured... sometimes!?

Appreciate the help,


I do however worry about the time when I'm unable to get it to start, hence I need to post here.

Hey guys,

Everything has been fine with my 3 and a half year old ADVENT PC, and I've been successful in upgrading parts such as DVD Drives, adding extra RAM and installing my new graphics card. Just this morning, it gave me the error, and with 2 Ctrl+Alt+Delete restarts, it's working perfectly, hence I can type this.

Also, if I do press Ctrl+Alt+Delete and the PC restart, it is normally successful, and will boot up Windows perfectly. This happens 2/3 of the times I turn on the PC. However, in the past few days, when I boot up my PC, it stops at what I believe the DOS screen (part with BOOT FROM CD etc.) and will say A Disk Read Error Occurred.

Unfortunately I cannot be specific about hard drive model or anything, as I just don't know, but if this is necessary, could someone please tell me how to find out! Press Ctrl+Alt+Delete to restart.

Samsung SSD - "A disk read error occured Press ctl alt del - SOLVED"

The only reason we don't use it more as a troubleshooting method here is because it's a gambit that only sometimes works and since one has to reinstall the OS anyway, why not focus on doing a perfect Clean Reinstall Windows 7 that 95% of users don't have anyway?

I run the Vista repair utility on the install disk - no help. That tutorial contains everything known to start the OS. Good luck all.

I was formatting a seperate HDD using disk manager. It is likely the rescue install restored your SSD install's boot and if it was able configure a Dual Boot then I'd think RebuildBCD could have done the same. Rescue installs are interesting because of the access you get to the stranded OS and how in many cases they will configure a Dual Boot or allow you to do so with EasyBCD. The dual boot setup process must have rewritten the boot up files on my SSD.

The solution was simpler - when I first installed the second copy of Vista on a different HD, it setup a dual boot configuation. Importantly, however, the repair utility saw the Vista installation just fine (and after I ran it repeatedly it told me there were no errors). From the dual boot menu, if I selected the second Vista install listed - BAM - it loads up my SSD Vista just fine, just as I left it. So before trying a fresh Vista install on the SSD out of desperation (before deciding SSD had gone bad), I decided to install vista on a different HD in a dual boot configuration with the intent to then attempt to v...

Solved: SATA installation in XP = "A Disk Read Error Occured. Press CTRL+ALT+DEL to restart"

If there's a driver issue, it would have all the drivers needed on the Hard-Drive wouldn't it? I've tried the drivers that came with the motherboard and no-go.

I recently built a new PC, however I'm having a problem installing Windows XP onto my SATA drive.

Press CTRL+ALT+DEL to restart" when it's supposed to continue with the installation. EDIT: If I made a direct copy from an IDE drive onto this SATA one, is there a chance that might help? It works perfectly if I use an IDE, but this is what happens with SATA:
-Goes to the setup screen and puts on the necessary files.
-Asks me to format.
-Starts the 15 second restart timer, then restarts.
-I change the boot order to HDD first.
-It tells me "A Disk Read Error Occured. Motherboard: Asus A8N-VM CSM
Processor: AMD Athlon 64 3700 1MB L2 Cache
Case + Power: Antec Sonata II 450w PSU
RAM: Crucial Rendition 1GB PC3200 x 2
HDD: Seagate Barracuda 300GB 7200RPM 16MB Cache SATAII
GPU: Radeon 9600 XT AGP

Fixed it simply by making a clone of my IDE drive on my SATA drive :-].

One time, I believe it said something about "Boot", but it flashed on the screen too fast and restarted to see what it said. I've also tried with no drivers and it still gives me this error.

A Disk Read Error has occured.. HHEEELP pls

HDD model: Hitachi
using an acer aspire 4736z
vista home basics x32

Agreed that the HD should not fail after a few months. after doing that my laptop froze and after i rebooted it i got the "[IMG]file:///C:/Users/FRANCI%7E1/AppData/Local/Temp/moz-screenshot.png[/IMG]interrupted operation insert the recovery cd or other recovery media and reboot your pc" error, after scouring the net for possible solutions, i found almost none that were effective, or at least none that i could really understand enough to do by myself... then after reading about using their recovery disk to fix the MBR.... Good luck

But some products are defective from the day of manufacture, that is why there are warranties. which i did.... If you have a problem finding the test, maybe I or another member can help.

Most have a method to test the HD. or do i need to mention more studd about my laptop? my next problem became this "disk read error"

i wanna use the system recovery disks i have but if possible i wanted to save my data

forgive me coz i reeaaaally don't know what to do, let alone explaining vivdly my predicament

i'm reaaalllyy not very much of a techy i'm a noob pls help
will these help? If at all possible I agree, try and save your data.

Try going to the website of the mfg.

A disk read error occured. Press alt-ctl-del

I can restore the backup copy of the partitions from Acronis using a USB Drive adapter cable and the problem goes away. I used to be able to run the XP disk to start the repair console, yet now the repair console startup hangs. I have a DELL Inspiron 600m Laptop. Say restoring all the data since the backup was done previously.

What about splitting the drive into two logical drives? I updated the BIOS to the latest from DELL and that did not help. I can access the data on another system using the USB cable. I could buy this HD right now online.

Everything worked fine until this year when I hit the magical space usage of 100 Gig. The HD is still under warranted and can be replaced, but I want to make sure of this before going this route. It seems like the MBR/Boot partition is getting trashed/overwritten by something.

Replacing the SATA cable fixed it. I don't want to go this route. After I copy a file that puts me beyond this boundary the system get the "a disk read error occurred.

I am having this issue repeatedly.

Any ideas? There is speculation on the web (via a google search) that these large drives (120G and above) are not usable on the 600m, but I just checked the Dell site for user installable hardware and found my exact WD Scorpion model (wd1600beve) listed in the "upgrade" section for my system.

A disk read error occured on external USB HDD

Suddenly it cannot boot again like WinXP on other USB HDD. "A disk read error occured." I cannot find anything wrong with USB HDD.

I install Windows XP to external USB HDD and Windows 7 to other USB HDD. How can I know if this is hardware defect or recently Windows apply patch/update that make it cannot boot from USB anymore ? Windows is not meant to boot from a USB HDD.

Install the HD internally or via SATA converter cable, then run Paragon Virtualization Manager to adjust it to the new hardware.

USB HDD for years because internal HDD is too small at that time and I keep it that way until recently I got problem. I change from Dell620 to HP8560 and immediately it cannot boot from WinXP on USB. The only message is "A disk read error occured.

When Win8 RP expired, I keep using it without upgrade because I usually use it for less than 2 hours. Press Ctrl-Alt-Del to restart". I have been using boot from ext.

I upgrade it to Win8 Release Preview and work smoothly. I try to install again without any error during the installation process, but same error once it boot from ext USB HDD. I just cannot boot from it. I can still access all files on USB HDD from any system.

USB HDD. I still can boot Win7 on other ext.

Satellite P20-304: Disk read error occured

I also used the recovery cd's but that was useless.

When I turn on my laptop it appears an error message saying: "A disk read error occured. regards,

If you have tried to restore your system using the recovery CDs and this also failed then It would seem that a new hard drive will be needed.

Does anyone knows what to do? I did that several times. Press ctrl+alt+del to restart".

A Disk read Error Occured on Starting Windows

A disk read error occured. Other partition is fine tho?!?!

i couldnt run control panel to *enable* system restore while being on safe mode will nto let me sys restore. i tried formatting C and got the error that it was in use but i proceeded anywayz. i ran avg and delted the virus. i then restarted the computer and got the message ctrl alt dlete restat.

i then proceeded to format drive c and eventually reinstall xp. its an eee pc, so it does not have a disk drive. ( i have a portable but do not have the xp recovery cd with me) (* i kinda need it done soon)
i dont understand why it wont just boot w7. the format did not work. I DO NOT WANT TO LOOSE the files in w7!!

ive tried putting in new registrey keys etc... This is your issue

Your (D) drive needs your (C) drive to get to the point so you can tell it to load and since your (C) is corrupt you will not be able to get into your (D) drive for it works from the master boot record of the (C) drive , so this makes both drives non-accessible technically

What you need to do to get your files is but a tool from a repair shop near you or from a online store / this tool should only cost you from $20 to $30 depending on where you buy it

You will need another computer with 2.0 highspeed usb ports but this will work on slower usb ports

You will need to remove the drive from the computer and atach to the tool then hook it up to the working computer and then you will be able to access the drive as if its an exsternal drive and recover your files and explore the (D...

A disk read error occured press CRL ALT DEL TO RESTART

Bring up and see if your optical drive is now seen.

Replug, the boot to bios. Please help. Set bios to default.

CRL ALT DEL DOESN'T DO ANYTHING. If so, the bios will recognize your hard drive, but you still will have to recreate your partition. Recently, I formatted my hard drive because I wanted to start all over. Next time I booted up and THE error A Disk read error occured pres crl ALT del to restart.

please help me! Accually it was a partition from my hard drive. So I booted into my bios and the hard drive was still detected.

If this is correct, continue. I hope my hard drive isn't dying because it is still recognized. Bios won't detect CD ROM so I can't boot from windows 7 CD. You may want to unplug your computer and make sure the power and sata cables are securely connected.

Hey this is my first post on this forum. Has your CD-Rom been detected prior to the format? BIOS does reconize it but when I set it as 1st boot device and boot up, I get the same error. I do have a windows 7 USB.

A few days ago, my mother's laptop was working fine until the screen froze. Press ctrl-alt-del to restart".
I tried that, but it didn't work.

A disk read error occured: Ctrl+Alt+Del restart

I fear this is a complete HDD failure and is not recoverable although the drive is still listed in the BIOS. My laptop is a slowly dying Acer 7520 Aspire with a 320GB Western Digital SATA drive. Sorry if it's a bit vague, any ideas?

I have alot of data on the harddrive which I would like to retrieve, most drawings and music. Put it in another machine, and see if you can copy the files from it. Immediately remove the drive from the system to avoid data loss. I might aswell mention that 2 usb ports and the Ricoh flash stick drive are nolonger usable, they just don't detect anything that I put in and on the odd occation when they do, they always fail to install the drivers.

Hard rebooted it only to find the thread title "disk read error". I have tried booting from an XP cd to see whether I can get into the recovery console but all I get is a error telling me that now HDD have been detected. I guess the last line of action I can take is to buy an external caddy and see whether I can recover my data via another computer or even use norton ghost or the likes. It was all working fine (apart from the few known hardware failures) until one day I booted it up to play descent and it hung on the desktop, I think this may have been after the system went into hibernation due to low battery.

Do not write to the disk any more, or try to boot from it.

a disk read error has occured-dell 8100

Some have a screw and some don't to hold it in, others just a release on the bottom.Let us know what you find. If not you may have a bad hard drive, OR the drive may have gotten slid out of its docking socket. I have a dell laptop 8100 inspiron- bios A15- also what would be the boot order for this, or how can i get around this problem.

If so, just push it back in until it clicks. I need to get out of the same screen, every time i restart, message says-a disk read error has occured-press ctr-alt-del to restart.

Disk Read Error Occured - No XP install Cd to repair

Any ideas? But it wont actaully repair the disk, just scan it

I've used diskcheck via cmd on the boot cd but it states there is a master boot registry failure (i think). But it just happend again and again.

XP Recovery Console CD Image with autofmt.exe for formatting
Recovery Console ISO Image (original)

A disk read error of any kind usually signals the end of a disk. It is doubtful that the MBR has anything to do with it. My laptop is not loading up, after about 20secs it states "Disk read error occurred- CLT+ALT+DEL to restart. In a little bit of a situation.

Run chkdsk /r from the Recovery Console and see what it says about bad sectors.

I've downloaded DiskInternals Boot CD and it will start on this. I've been reading around and everyone is saying just use the xp install disk to repair the master boot, problem is I have moved that many time is the past 2years I have no idea where that CD is. If you have a recovery partition, using fixboot or fixmbr will destroy the proprietary MBR and prevent you from accessing the recovery, so be sure you don't have one.
