Disk Error

Jul 26, 2009 11:36PM PDT

I hope someone can help me here... I noticed that my computer was slugging a bit, so I attempted to run my anti-virus software, but none of my programs seemed to be responding long enough to complete any tasks-
Windows Defender scanned without issue, but when I attempted to restart my computer, it comes back with the black screen saying
"A disk read error has occured, press Ctrl+Alt+Del to restart" and when I do that, it just continues to cycle through the same screens, and I can't get into Windows at all.
Is there anything I can do? I really don't want to lose all my files- as I had attempted to make a back up but wasn't able to in time.

Running Acer Aspire 7720Z series laptop
Model number ICK70
Windows Vista

Any help would be greatly appreciated! Thanks in advance,
Rachel

First. Try this.
Jul 26, 2009 11:41PM PDT

Turn it off. Remove AC power, then the battery. Now press and hold the power button for 1 minute. Yes if this applies to your machine it is only seconds but I found people to not follow the directions and not hold the button long enough.

Let go of the button, insert the battery pack and then the AC power. Try again.

If it fails we then think about data recovery. Here's what I do next. Read http://forums.cnet.com/5208-7588_102-0.html?messageID=3080838&tag=forums06;posts#3080838 where a member shared how they used another CD to gain access to and copy out their files.

Jul 26, 2009 11:47PM PDT

Turned it off, removed ac power and battery- held down button for one minute, then plugged battery and ac power back in, turned on- still "A disk read error occured" It didn't make any sound, no whirring to start up, nothing. *sigh*

Next step
Jul 26, 2009 11:49PM PDT

And I'm not really sure from reading that thread how to proceed... I need to buy an external hard drive, is that what I'm reading?

- Collapse -
I can't tell you that.
Jul 26, 2009 11:54PM PDT

I don't know what you have to work with. I can't know if you would boot up a LiveCD and what you see or if you would email files out of the machine to yourself.

Solutions are abundant but until you decide what to try and if you can't try it then you head for a repair counter.

-> BUT WAIT. I forgot a BIG thing. What else is plugged into this machine? Any printers, memory sticks? Is there a CD in the drive? Floppy in the floppy drive?

Details matter.

again, thank you :)
Jul 27, 2009 12:27AM PDT

I guess I will try to figure out how to get the LiveCD going- not sure how I'm going to manage without an external hard drive- there's nothing else connected to my computer- this all seemed to start after I put a scandisc memory card from my camera into my computer, and since then, nothing has worked properly.

- Collapse -
Then try the LiveCD methods.
Jul 26, 2009 11:50PM PDT

Longer reply below. The battery out, etc. method is not a sure thing but I always give it one try since if it works we can say we dodged the bullet.

How to fix.
Jul 26, 2009 11:49PM PDT

I see you asked how to fix in the other discussion.

There are TWO issues to solve.

Issue ONE. SAVE THE FILES.
The other discussion was not unlike what we discussed at http://tips.oncomputers.info/archives2004/0401/2004-Jan-11.htm

Why I noted these is that there is nothing scary about using a LiveCD and it can save the files if you are lucky. However if you must insist for even easier methods then it will cost a lot more. For example read http://www.drivesavers.com and take the machine to a repair counter.

Issue TWO. Fix the machine.
Given the price of a hard drive is less than 99 bucks I think I would slip in a new hard disk and use the RESTORE MEDIA that you made or were supplied with the machine. If you do not want to do this then you go to a repair counter.

Thank you
Jul 26, 2009 11:52PM PDT

sorry- I'll admit I'm extremely frustrated, as there are photos of a deceased relative on my computer that I was stupid enough not to back up, and now I'm a mess thinking I can't get them back. I'm going to write down the steps from the post you sent, and attempt to figure this out. My computer is under warranty, and if I sent it in, I'm sure they'd just install a new one, but I doubt they'd give a crap about the files I'm trying so desperately to save.
Thanks for all your help, I'll let you know if it works

Okay- I downloaded the 699mb Ubuntu file to my computer, burned it to a CDR, and then put that into my computer. I then changed the Boot menu to boot from the USB CDROM: (that being first in my Boot Priority Order)
and still, I get "Disk read error" screen.

does this mean it's fried?

Sometimes I find
Jul 27, 2009 2:09AM PDT

New to CD recording folks that put the .ISO file on the CD. Let's use another link and article to see how to make a proper Ubuntu CD.

"I mentioned earlier that the Ubuntu file is an ".iso" file. An ISO file is a disk image and you have to burn it to a CD in a certain way for it to work. You need to have a program that can burn disk images to a CD. Windows does not come with a program to do this. If you don't already have a program like Nero or Sonic RecordNow!, you can download a free program called CDBurnerXP Pro."

still
Jul 27, 2009 4:03AM PDT

I did this- trying the disc burn twice just to make sure I had it correctly downloaded, and it still will not work. My computer powers up, I hear the whirring noise, the Acer screen pops up, then I hear the whirrig of it attempting to access my CDR drive, and I still get the Disk Read Error screen- I guess I'm out of luck. thanks anyways~!

We can put this on USB sticks too. But.
Jul 27, 2009 4:08AM PDT

I have run across folk that put the ISO "file" on the CDR.

Do this. Slip that CDR into a working machine and tell me what files you see on the CDR.

Jul 27, 2009 4:34AM PDT

It appears you have made the CDR proper but can't boot from USB CD/DVD drive.

Can you reveal why you selected the USB CD drive? This laptop has a built-in DVDRW drive so is there part of a story missing here?

boot
Jul 27, 2009 4:46AM PDT

when I went into my setup to select a boot location, these were my choices

1:IDE 0: WDC WD1600BEVS-22RSTO
2:IDE 1: HL-DT-ST-DVDRAM GSA-T20N
3: USB CDROM:
4:USB FDD:
5:Network Boot: MBAv 9.4.5 Slot 0500
6:USB HDD

since that was the only one I saw that had CDROM in it, I thought that was the correct one to use- those are my only 6 options

- Collapse -
Item 2 is your laptop's DVDRW drive.
Jul 27, 2009 4:50AM PDT

USB CDROM is an option if you have such.

I think you are very close to seeing your files.

Jul 27, 2009 4:52AM PDT

success... I got into the Ubuntu program- but not sure how to locate my files using this program?

Almost there.
Jul 27, 2009 4:58AM PDT

"How to access my Windows data?

After downloading and burning the ISO file, you boot from the Live CD on your broken computer. When the Ubuntu menu shows up, you select the first entry which should be something like ?Try Ubuntu without any change to your computer?, depending on the system version. Once the operating system is loaded, you go to Places -> Computer which will show you all available drives. Now, try to open your Windows drive with a double click. If you can access the drive, congratulations! You can now backup your data"

From http://www.notebooknotes.com/blog/how-to-backup-your-broken-windows-pc-with-an-ubuntu-live-cd.html but I cut out the important part for you to read. Don't read the other text there yet as we only need to get to your files.

Good and bad news.
Jul 27, 2009 5:13AM PDT

Let me share a link but don't read it yet.
https://bugs.launchpad.net/ubuntu/+source/gnome-mount/+bug/132279

Ok, that message does happen if the NTFS volume is "dirty" or in need of a CHKDSK run.

To recovery from this we need a bootable XP or Vista CD/DVD. One that we can get to the Recovery Console.

-> Thanks for sticking it out so far but you are making progress. Let's see what OS CD you have to work with.

Jul 27, 2009 5:16AM PDT

I have no cds. I ran all the codes it told me to and it says "The file system wasn't safely closed on Windows. Fixing.

but it still doesnt' let me in.

should I attempt to download a recovery disk?

- Collapse -
Be very careful what recovery disk you choose.
Jul 27, 2009 5:35AM PDT

The disks I've noted are not known to wipe the drive like most recovery disks do. We only need to get any Windows XP or Vista CD/DVD that matches your system OS to boot that and in the recovery console type "ONE" command.

It's sad you don't have such a CD. I see a 4 dollar one noted at http://www.ocforums.com/archive/index.php/t-433782.html but let's see what you find.

Looks like the right thing.

But given it's a torrent I can't supply the steps to download it. But to make the bootable CD will use what you learned so far.

what to do
Jul 27, 2009 5:59AM PDT

I'm not sure I understand your last post- should I attempt that restore? not sure what my next move should be at this point.

I can't tell you how much I appreciate you taking this much time out of your day to help me. Even if I don't get everything back, you have helped me out more than you know, and restored my faith in people helping out strangers.

That download is
Jul 27, 2009 6:04AM PDT

Not a restore CD or DVD. It's just what's needed to boot Windows and get to the recovery console so we can run the one command to chkdsk the drive and hope for the best.

My reply is that I see its not a simple download but a torrent. That could be more work to walk you through what that is, how to download than what we covered so far.

If we must save files and we reach the end of what we can do ourselves the next step is costly. Read and ask at http://www.drivesavers.com

For me I find buying a copy of Vista is cheaper and worth the investment.

Okay- I've found Bootdisk.Com, and am fully willing to pay the $4 for the disk- but I have absolutely no clue which one I need to download... I see loads of bootable windows files- none of them say Vista, which is my Windows version- so where do I go from here?

I downloaded the file and copied it to a cd, but when I put it in my comp, it doesn't do anything. Not sure what I'm missing here...
