Need to stop CHKDSK in progress
Posted 07 July 2010 - 09:54 PM
With the system suddenly becoming increasingly jittery, and slow, and locking up (only when accessing one of the partitions on the second drive), I decided to run a CHKDSK at startup. BIG MISTAKE.
During stage 1, I came up with 4 file record segments as unreadable.
During stage 2, it has managed to hit 11 percent complete (it took almost an hour for this), but there it sits, without moving (it has been as 11 for about 30 minutes now). Now I am concerned that CHKDSK may be re-writing (or attempting to) my data, destroying it even further...
I have been googling like crazy on my laptop; every time I find a thread somewhere, the inevitable answer is "why do you need to run CHKDSK?" That does not help. I need to find out if it is safe to stop the computer, and how to do so (pull the plug?).
I can pull the drive out, and slave it into another system if need be, but I need to get the data off safely. I cannot simply put it into the new server as the second drive - there would not be enough room on the first drive to get the data off of it.

If I had thought first, I would have tried a disk utility first to make sure the disk is functioning properly. I realize MS recommends making a data backup before running CHKDSK. Ironically, that is what I was trying to do...
This drive has archives from my previous company on it, and I now need the data (of course!). We just shut the company down, and I had only one choice for saving the data - a quick file copy to my own second drive. Now I was going to put it onto a raid'd server, then take my time burning to DVD's...
I may just have to have a (very) sleepless night. I am worried that -even if it does complete - it may have "re-written" the data, and scrambled it even more...maybe that's not realistic, but I;m not sure.

I truly appreciate your help and advice. I think I'll deal with no sleep tonight, and hope I don't need to unplug the box...

Any idea how long stage 4 or 5 take? I always understood stage 2 was the long one...

I suggest...expect the worst.

I booted with SystemRescueCD, and am currently running ddrescue to copy the old data to the new drive. I am currently at the 250000 MB mark, with a single 523kB error found so far. I think there was a total of about 350 Gig of data on it. FWIW, I was able to access most of the data without issue, so I am hopeful that the data loss will me minimized. But only time will tell. (I'm hoping for the best, but planning for the worst.)

Now I am at the 283000MB mark. It has slowed a bit, but still only the single error showing. Of course, that does not mean that the data is safe - it could still be very well scrambled beyond repair. It simply means ddrescue is doing a wonderful job of copying the data...
