Windows 7: Frequent hdd access, horrible performance

The rellocated sectors means that sectors on your disk were found to be bad and have been replaced by good sectors that the drive has kept in reserve. This can effect performance significantly and could be the harbinger for complete failure of the disk. I would back it up and replace it immediately.

I would quit defragmenting that drive as well to limit damage. defragmenting can move bad sectors from one file to another corrupting more files.

Your power on hours suggests your drive may be well within it's warranty period. If so then backup and replace.

Chkdsk /r found nothing. I've verified that the problem occurs in the guest account, just much less often. I wonder why that is? Anyway, everyone seems in agreement that this is a HDD problem, so I guess it's replacement time.

In case you were still interested, mjf:
Frequent hdd access, horrible performance-crystaldiskmark.png
I noticed your thread here. Is there any reason I should expect such a performance difference normally, or is this the result of the reallocation etc?

did you do chkdsk /f or /r? Looks like /f which only checks t logical consistency in the filesystem not for bad sectors (/r finds and corrects bad sectors).

If it were 1 or two sectors involved, it probably would not be a significant worry. But 373 bad (relocated) sectors is pretty serious.

Good luck!

I suggested chkdsk /r but if under warranty I'd just get a replacement.

I thought I'd run /r. My chkdsk /f results are on the previous page. You can see the two additional stages - verifying files and free space. It appears to report 0 bad sectors. CrystalDiskInfo reports 180 bad sectors (just checked again and it's up to 188). On the other hand, that's raw data, not sure if I'm supposed to somehow interpret it. Where do you get 373 from?

Crystal disk mark is reporting the RAW SMART counts, which are in hexadecimal. 173 hexadecimal (your second post) = 373 decimal.

188 hex = 392 decimal
