---- System Error on Bootup: Checking and Repairing a Hard Drive
kaled - 9:40 am on Oct 6, 2010 (gmt 0)If you were using /f, chkdsk wasn't scanning for bad sectors
|The situation got worse over time, but chkdsk continued to report the sectors as OK... |
fortunately, the bad sectors were in an area where there was no data...
I have lost all trust in chkdsk as a result
I'm the brutal one round here that doesn't believe in subtlety...
Since you weren't scanning for bad sectors, there was zero possibility of finding them in unused areas of the disk.
Your loss of confidence in chkdsk resulted from your own lack of understanding.
Drive imaging software necessarily scans every sector of a drive whereas a basic error check simply looks for cross-linked files, etc.
It's also worth noting that a medium-level program (such as chkdsk, I think) may not detect failing sectors since such programs normally only go as far as determining whether data can be read or not - they don't count the number of attempts required or the number of corrected errors, etc. Also, I don't think such information is available without talking directly to the drive (i.e. bypassing the bios and/or drivers) but I'm not certain.
I believe some drives automatically detect failing sectors and move the data transparently to other physical sectors (remapping the drive) but I don't bother to follow hardware developments these days, so I'm not sure.
