[EclipseWebJS2]

OK, somebody tell me something: Does a bad cluster in a file mean there's physically bad sectors on my hard drive ... again?!?

0 KB in bad sectors.

But the test result didn't reveal any bad sectors

[mouse]

Crosslinked files are part of the problem. All drives have bad clusters from time to time and might even have bad sectors. Usually chkdsk will move them out of service and replace them with good clusters and usually move files if a whole sector is bad. Drives are built with extra cluster for cluster replacement.

And just where are those extra clusters? In that 7 megs of unallocated space on my HD?

 

Here's something else-- I was just running my hard drive tools, and the tool says I had 15 heads for the disk instead of 16... ??

 

Another question -- does the boot-time CHKDSK make copies of the crosslinked clusters?
