I have a Sony VAIO PCG-FR700 laptop (Detailed here). I was downloading a file and had it scheduled to shutdown ( shutdown.exe -s -f ) a couple of hours after the download was finished. I expected it to be shut down but found it to be on since the gree light was on (obviously indicating the laptop is on) so I opened the screen and found it to be completely black. I moved the mouse via the touchpad which should've changed the screen from black to the desktop, but it didn't respond. I pressed the power button, and it automatically came up with the Sony logo then when I expected the Windows logo, the computer gave me about five seconds of a blank screen with only a cursor. Then this message comes up:

A disk read error occurred
Press Ctrl+Alt+Del to restart

That's as verbose as it gets. Restarting just gives me the exact same routine. I can access the BIOS but AFAIK there is nothing there that can help me.

Is there anything I can do? At least getting some files off the harddrive is ok with me but I would prefer to use it like normal again.

PS: I had my laptop using the Power Scheme 'Always On' (with the Windows default settings) and it was plugged in. What Windows does is turn off the monitor after 20 minutes if the laptop is plugged in. I have had previous problems with getting the monitor back to normal after using the power schemes so this might have something to do with it.


Could I possibly remove the harddrive and put it in any other laptop? The problem might be an overheated component and not the harddrives fault...

If you still have your windows install disk, you could try to repair it...

i didnt read any of that...

nice to see you posting again lg  Smiley

I had a laptop / coffee merge on Sunday. Not nice but at least the hard drive survived, so it's a new laptop and slow recovery.

So I think: "Stuff it. I'll just format the harddrive and recover the files afterwards."



You figured you'd get your files off a newly formatted drive?  Not sure how you intended to do that.

I choose to fill all the sectors of the harddrive with zeros, it said that it doesn't permenately delete data so I checked that box and moved on.

my computer is no longer recognizing that there is a harddrive within it at all. The BIOS says that there is no Primary And the WinXP Pro CD and the Recovery CDs agree with the BIOS, there is no harddrive in my machine


Just a few thoughts.  If your drive was to be full of zero's, where would the data fit?  It needs ones too.  Sounds like your data is toast. Also sounds like your drive has a physical problem. 

Laptops aren't impossible to fix, they're just a pain in the arse.  The HDD will generally sit in a removeable bay of some kind, or in an access panel on bottom.  Someone will have to look to ensure it's securely connected, contacts aren't worn, has power, etc.  Beyond that, you may need to replace the drive.

Well supposedly filling it with zeros doesn't permeately wipe all the data of the hd (according to Sony) so I thought I'd do it.

Overwriting the data on the disc only once will still leave some residual magnetic traces, so with advanced, expensive data recovery equipment it would still be possible to get the data from it. Not anything you're likely to own, though. Most disk wiping solution that aim to truly make data unrecoverable will overwrite it several times, not using zeroes but random patterns to make it as difficult as possible to get back the original data. Of course, the only way to truly destroy the data is setting the disc on fire. Or rolling over it with a steam roller. Or... well, you get my drift.

Typical data recovery tools can only recover data if it has not been overwritten. A format doesn't wipe the disc, it only rewrites the file tables, which makes it possible for tools that do raw disc access to get at the old data. As soon as new data goes over the old, simple tools no longer do the job.
Right on, Loadsgood!

You managed to mess up your system more than me. Smiley

How could something this drastic happen overnight? I'm thinking maybe a virus was downloaded while I left it online


Not everything is a virus.

In your case, and probably 99% of hard disk problems its most likely a mechanical failure. SMART monitoring might have picked it up, if you have it, but it won't always do.

And Sony weren't lying, they tell you it doesn't permanently erase data is so you don't assume you've definitely wiped all confidential data before selling a system on.

I have a Sony Vaio laptop with the same problem. 

I left it on overnight---with programs open but not downloading anything or doing anything overly taxing---and this morning got the same error message you got. 

It was the same situation.  I left it on for an extended period of time.

I kept rebooting and kept getting the disk read error.  I tried the recovery disc, it started, then said it could not complete recovery.

I had this problem once before.  Somehow it got fixed, but I don't remember how. 

I think it was something simple like I just kept trying to reboot it, removed the battery and power supply, etc.  Something worked.  I immediately backed up my hard drive. 

Also, let me note that occassionally the HDD seemed to make a weird light clicking sound (when it worked).  And, as it's trying to read the disk error now, I hear that sound again.  Is that a sign of a drive gone bad, you think?

Does anyone know why Sony laptops do this?

Hearing that the same thing happened to Loadsgood just by leaving it on "too long" as I apparently did, makes me think this must be an issue with Sony's laptops.

How to resolve this without my losing my most recent data?  It has been a month since I backed it up and there's lots of work I'd like to recover.

Is Knoppix a realistic option? (I don't fully understand that option).

Thank you,
Peter
Nah guys, it isn't just Sony laptops. I have a Toshiba and it has the same problem.

Last night, I left it on for about 3 hours downloading msn 7.5 (dial-up internet) and straight after the download finished it just froze. I saw that the download had completed and gone to the desktop, but the computer just straight out froze.

I just turned it off, assuming everything would be fine in the morning (it was too late to turn it on again) and got home this afternoon, hit the power button, and bang, "A disk read error occurred. Press Ctrl+Alt+Del to restart".

I'm not sure if I still have the reboot disk's...I don't know what i'm going to do Sad
Let me know what you come up with.  As for me, I'm opening mine up, taking out the hard drive and putting it into an external hard drive enclosure to see if I can get the data off it via my other computer here.

Best of luck!

I think I'll keep Linux away on this one Beer, I'm too much of a novice to understand how to go about installing it, not to mention the slow download time (and I'm not going to pay money for a Linux Distro on CD either).

I think Beer's suggestion on trying to load with Linux is a valid one.

With Linux's incomplete (Duh!) NTFS driver, it sometimes permits you to mount a corrupted NTFS volume that is inaccessable by Windows itself.

It's a convienent way to test if a drive is really end-ed it's life if you got a  live-cd in hand.

If the filesystem is mountable, you'd see it automatically mount it for  you under "/mnt/windows".

If not, you can follow Beer's instruction to make a try. Since Linux by default only mounts NTFS as "read-only", and with Beer's intruction you're only working on a image in memory, unless you mistyped the "dd" line, there's nothing you can make it go wrong.
Hey! We did all this, we formatted, we restarted, we reinstalled and we cursed like no other! Then we changed the flat IDE cable, and all worked! Man! JTR
I've been having "A disk read error occurred... Press CTL-ALT-DEL" for about a year now, and I've treated it lightly, and found that repeated attempts to reboot have always succeeded, typically pressing the hard reset button on the puter, and sometimes just powering down and powering up. 

It got a bit scary just now, repeating "disk read error" about six times in a row, and I wondered whether finally the disk is on its last legs and getting close to being unreadable.  This propelled me into Googling "A disk read error has occurred", to look for solutions, and finding myself on this page. 

Now that I come to think about it, I  probably should make serious efforts to fix it.  Since I always maintain a backup of partitions C: and D: on another hard disk, what I should probably do is jusf reformat the hard disk that has partitions C: and D: and then recover the backup to the reformatted drive...  Before doing so I should obviously test the integrity of the backup, just to make sure it works properly. And also I guess I should run an integrity check on the drive.

Staggr found that reformatting and changing the IDE cable solved the problem.  So I guess I'll add changing IDE cable to the "to do" list.  

Will report back.

hi. i am new at this. but i just got onto google to search the same problem my labtop has. it does the same exact thing  yours does.
but the brandofmy lab top is a toshiba. and the weird thing is, it wasworking perfectly fine lastnight before i shut it down. then i go and try to turn it on this morning, and i get the "disk read erro
