Disk read error has occurred...press ctrl al Solved/Closed

Question

Hello,

Is there any one out there could help me with "disk read error has occurred...press ctrl alt del to restart" after I tried to merge two partitions on Dell Inspiron 6000. Please tell me what do I need to do solve this problem when the computer boots up.  I

This is one of the most frustrating error messages you can ever deal with. Sometimes the fix is simple, sometimes it's a complete pain. Having recently dealt with this again, I thought I'd post my thoughts in the hopes that it helps someone else out there.

So you receive the dreaded "a disk read error occurred. Press Ctrl+Alt+Del to restart". Multiple restarts result in the same error message.

If you put your drive into another computer, or connecting it as a slave on your own computer, it will typically work fine, and no data is missing.

Because this error is not usually associated with data loss, DO NOT RE-PARTITION THE DRIVE. Your data is likely safe and sound.

Here's how we'll recover your data. Try each step below, in order, and see if your drive becomes accessible after each step. In my experience, you won't start seeing results until step 5 or so.

1. Run CHKDSK /R /P from the recovery console (it will typically find no error)
2. run FIXBOOT from recovery console (typically has no result)
3. run FIXMBR from recovery console (typically has no result)
4. Run the manufacturer's diagnostic utility, downloaded from their website (it will typically find no error)
5. Changing the drives from cable select to Master/Slave may fix it.
6. Replacing the data cable may fix it, but usually not.
7. Setting the BIOS to use defaults may fix it, but usually not.
8. Changing the BIOS drive settings from auto to user-specified, ensuring that LBA is selected may fix it.
9. Pulling the CMOS battery to let the BIOS lose it settings may work.

At this point, you may be feeling some frustration. :-)

If all that fails, here's what will usually work:

Ghost your data to a new drive, and use the original one as a slave. It will work. And all of your data will still be accessible. Your computer should boot normally. If it doesn't, or it there are errors, run the Repair Installation option from your Windows boot CD.


But why does this happen? Nobody seems to know why. The problem typically evades all forms of detection.

Here's what I've learned: this error message likely has more to do with a hardware interaction between the drive and your system than any actual issues with the drive. To put it one way, your motherboard and drive are no longer on speaking terms.

I don't know why the original disk has no problems being a slave. Perhaps it got tired of running the show. Perhaps it's preparing for retirement.

I hope this helps!

Hello, 

I'm having the same problem also. I bought an external HD and when i plugged into my Dell Laptop, the system froze. I turned off and when I restarted i got the Disc Error Occurred message - to press Ctrl+Alt+Del. And when the laptop restarts, it goes back to that message. What do I do? I don't want to lose all my files in the laptop, as this is why I bought an external HD, to store all these files. Please help... Thank you!

Here's the answer: these Dell laptops can only use about 120 GB hard drives. If you've installed a larger drive, once you reach the 120 GB threshold (even if it's just due to fragmentation) it won't boot. Don't ask me why. You can solve this problem, without reformatting, by taking your hard drive out, plugging it into another computer with a USB enclosure (very very cheap), deleting or moving some large files, then defragmenting. This drove me crazy for a long time until I found out the answer. The reason it takes 2-5 months is, that's how long it takes you to accumulate that amount of data.

Yesterday I bought a 500G 7200rpm Toshiba HD for my Lenovo T400. When I install XP, after all OS XP files were copied onto new HD, it went to restart from HD, then I got this kind of message:

A Disk Read Error, please press Ctrl+ALT+DEL restart....

I put HD into a USD enclosure, all file on C/windows can be accessed, because I could use achieve to compress all files into one files.

When I installed Xp onto new Hd, I had three partitions, and I used quick format all partition with NTFT format. I thought it was partition issue or format issue for the HD. 

Then I only used whole HD as one partition(500G), then used normal format(not quick one), (it took about one hours), then all problems solved, after this successful Xp installation, I went back to make C partitions 120G,  and only quick format this C partiton, and it was still successfully to install XP.

I am not sure which is the root cause of "A Disk Read Error, please press Ctrl+ALT+DEL restart....", in my case:
a) quick format not really mark the bad sector of HD?
b) at first the OS did not know which partition it should use to restart,

Anyway I hope these experiences would be helpful for the guys in the same situation, just as one guys said
" A Disk Read Error, please press Ctrl+ALT+DEL restart...." may have thousands reason....


Good luck to all guys in this forums,

Hello guys,  from what ive learnt the disk read error,  is created either not enough power getting to HDD, and low power could cause HDD to make 'mistakes' and corrupt its self. and te other more plausable culprit is partitioning/formatting.  if you partition or edit  a HDD , and  files are all over the place, sometimes  the boot sequence  gets messed up. and if the computer cant find the boot files, it will just read the HDD as  files and not a bootable option, bios ( boot) cannot read  a windows OS unless it has instuctions to do so, thus creating  a disk read error,  for those of you who NEED thier files or some of them, download a windows 7/Vista recovery Disk , jus google it u will find one soon enough :) its about 150mb and it will load up like your installing it but  the option to repair it will be there, when it says load drivers ( also displays your  OS above)  click load, and seard for your self.  now it will open a  box , and in there you can  explore your entire hard drive.. cut, copy, delete, paste. plus in your  external HDD or CD/DVD and copy the files onto it . now it wont have a copying dialogue box but it is doing it, i assure  you. large files will takes a while  ofcourse and u may be tempted to  stop it . but u can test that it works on a small file.  

After all files are backed up  you will now have to erase all partitions / HD structures etc. anything that  caused the fault in the first place. to do this you can use  various prorams like KILLDISK DOS program, burn to CD and run it at boot. it will load up its own interface and give you  plenty of  custom options to erase data to its  factory settings ( lots of  00000000)  but you want  the entire drive  gone for it to work , or  anything u reinstall will be prone to read errors because of the way its setup previously.. it will take 20 mins per 100gb, so if u got 500 gigs, it will takes 140mins

finally once HDD is back to its factory settings, insert your installation disk and ,  set ur partitions,  drives up and install. now your good to go i hope this helps everyone in this forum!

I had the same error with my hard disk 3 days ago. I had this error with my previous hard disk and was replaced with new one. New one is a segate. Previous one is a hithchi.  I was confused and went to meet the seller with the hard. Then We found that there was a error with my C drive in which windows xp was installed and also it is not accessible. Other paritions were secured and allowed  to access their data. After that I came home and foramt  C drive and installed windows XP again. Then Hard was working properly. But Unfortunately I went away from the machine for some time and came back.  Then I realized machine has a problem again. I pressed keys but machine did not respond.  I restarted the machine.  Same data disk error happened. I opened the case, checked the power cable, kept them tight with the hard disk and resart the computer. Marvelous It is working smoothly.  I think this error comes with an error in  power cable  or sometime it may be with a virus.

Hi I had this problem with a Compaq nx7010 in which I had replaced the previous hard drive, with a wd 160Gb drive about 2 years ago. I was reluctant to believe that I had to do a whole restore, as the diagnostics all ran well on the drive and I could see that all the data was intact. I tried fixing the mbx records, fixboot etc. I tried everything that I have read on this and other forums but no good until I remembered on obscure comment on a list somewhere. I put the disk into another machine. (I have a desktop pc with a cable adapter from 3.25 inch to 2.5 inch ide which I bought off the net for this purpose.) I then went to properties on the drive under windows, Tools and ran the defragger. Analyse said it did not need defragging and showed blue data with a small white space to the left. I defragged anyway and it did do a small amount of work and the white gap to the left was smaller when it finished. I shut down and moved the drive back to the laptop and bingo she boots. You bl...dy beauty. So it seems that when a drive gets itself into this state nothing will fix it except a defrag of some of the early blocks of the disk. Microsuck don't tell us about this anywhere as far as I can see. SOLVED!!

it is a simple problem indeed.
i think it was happening because of 'error format drive data'. OS cannot read which drive should be primary active,so it cannot read where the OS installation is.
the simple waya to fixed it :
1. change ur HDD as a slave on another HDD
2. format ur 'primary active' drive on the slaved HDD (the trouble one) using advance software like Partition Magic or Acronis Expert, and make sure u format it as 'primary active' not just primary or even logical drive.
3. install ur OS.
i've try this one and no same problem is back,
of course u still can copy ur data on 'primary active' drive before format it :)
have a nice try :)

I encountered this type of problem in one of my units in my internet cafe 15 minutes ago.

I was about to do the things listed here to try and fix the problem. But luckily, before I did, I decided to open up the CPU, pull out the power and SATA cable of the HDD, pull out the SATA cable for the SATA port as well. I then re-plugged both cables into the HDD and switched from the original SATA port it was plugged in to another that was available.

I was amazed that it worked. Now, computer's running as it used to again waiting for the next customer. ^_^
