Advice on HDD Sentinel report
August 7th, 2011, 14:21
Hello,
Just wanting to get advice on HDD.
Ran Crystal DiskInfo and returned:
Reallocated sectors count: 100
Uncorrectable Sector Count: 100
Then ran report via HDD Sentinel as attached. Snapshot is:
[b]There are 9 bad sectors on the disk surface. The contents of these sectors were moved to the spare area.
The drive found 12 bad sectors during its self test.
Based on the number of remapping operations, the bad sectors may form continuous areas.
At this point, warranty replacement of the disk is not yet possible, only if the health drops further.
It is recommended to examine the log of the disk regularly. All new problems found will be logged there.[/b]
Thanks

Not sure what level of reply you're looking for...
Any number of reallocated sectors is a concern, as it might be an early warning of the start of a problem. However with just one set of raw SMART data from HDD Sentinel that you've given, we don't know if those 9 reallocated sectors were reallocated ages ago (and the drive has been stable since then), or if this number has been creeping-up over the past few days. The prognosis in those two situations tends to be different, for example. What historical SMART data do you have, if any?
As always, you can't guarantee to predict when a disk will deteriorate, nor whether you will get much warning or not. What proactive actions you choose to take also depend on your attitude to risk, and how much it would inconvenience you if the disk failed unexpectedly etc. etc. Just make sure you have current, verified backups of everything that is on that disk (OS & data) using one of the available software packages, and then if the disk does deteriorate, it'll be less of a crisis.
