Been trying to run full disk image backups using the built-in image backup utility in Vista Ultimate 64-bit. Haven't made one since May (which was successful)--I just back up data files as needed.
BUt went to make a full disk-image backup last week, and Vista Backup went all the way thru to the end (took an hour) then, w/a big red progress bar instead of a green one, told me there were some "bad clusters" and the backup had failed. Error code was 0x8078007D (best I can recall). I looked it up on MS KB--couldn't find it. Nothing on Google even.
After that first time, I ran chkdsk, including checking for bad sectors (which yes, I know, are different from bad clusters). Took forever, but thought it did okay. Was watching when it finished, but the info flashed by too fast to read, tho I think it said there were about 6 MB of bad clusters, so obviously it didn't fix it.
I got worried about the drive--a 750 gig Seagate 7200.11 SATA II (Model#ST3750330AS)--and ran Seatools to check the sectors. Seatools reported all was well--no bad sectors.
Tried another Vista image backup again today--and again, another failure due to bad clusters. This time I opened a command prompt, and typed "chkdsk.exe /B". Ran it again. It took much longer this time, seeming to get hung up at about 19%, then after an hour or so got cooking and finished. Again, I tried to watch the results screen, but it went by too fast.
I found an area in "Administrative Tools"/"Computer Management": "Administrative Events". Among many error lines saying the disk has a "bad block", I found the warning that the "Backup completed with warning(s)-Volume 'C:' has developed new bad clusters. This may be an indication of problems with your hardware. 78848 bytes have not been backed up as they could not be read. Please run chkdsk /R on 'C:' and rerun the backup"
I didn't find this until after I ran chkdsk /B, but chkdsk /? says /B implies /R. I didn't have time tonight to try another backup, plus I also wanted to find the chkdsk log to see if it did any good--no point in running another backup if Vista Backup still chokes on the bad clusters. (I don't understand why it just doesn't skip them and finish the backup.)
I should add that--between last week's backup attempt and today's--I installed an HP MediaSmart Windows Home Server EX475. I did succeed in making a backup of C: to the HP server; at least it said it was successful. I should also add that I used Vista's simpler "Back Up Files" part of the "Backup Status and Configuration" utility, to at least backup up my data files--that did work, so at least I got my data files backed up.
I'll try another backup tomorrow, but I'd really like to see the chkdsk log file first, if one even exists. Is there one? If so, where is it? I've been searching all thru my system, and can't find anything remotely like it.
Right now I'm kind of freaking out. The system seems to be working fine, but obviously something is lurking beneath the surface. And I suppose cloning the current C: drive to a new one would not do any good, right? As it would simply also clone the bad clusters?
I'm also not getting why chkdsk isn't just fixing the clusters. In the "old" days, I remember they used to be called "lost clusters", and chkdsk would attempt to recover them and give them cryptic names, to see if any data was recoverable. Now it hardly tells me anything.
So Seatools is telling me the drive itself is fine, and Vista is telling me I have bad clusters. What should I do here? And where is that d@mn log file?
Thanks.
