Bad Sector Count
in [Storage]
|
From: Keith on 26 Dec 2006 07:43 My Win XP Pro PC suffered a BSOD yesterday telling me that part of the registry was corrupted. I restored the OS from my Acronis True Image backup but the bad sector count has increased from 3 to 5. Not knowing much about these things, is it time to buy a new HDD? Here's the SMART report. Thanks.

It just means that ECC is faster that retry on reads (i.e. fast, but less acurrate positioning). > C4 Reallocation Event Count 0 253 253 0 > OK: Always passing > C5 Current Pending Sector Count 0 100 100 5 > OK: Always passing Hmmm.

Best run a long-smart self-test. It will do a comlete surface scan. Lets see whether the pending sectors turn into bad ones. As it is, the disk has zero bad sectors and this may be some other problem, e.g. a driver issue or a controller problem. Post the SMART status of this disk and the self-test log here, after running the test. This may very well be a temporary failure, e.g. from a power-spike on writing or the like. The long SMART self-test should identify that.... > [ WDC WD1600BB-98DWA0 (WD-WMAEK1279192) ] Ooops, a WD. Ceapest disks on the market.

No idea. I use the smartmontools, there it is just "smartctl -t long <device>" Arno
