Hi

There seems to be a problem with my hard drive, it has a high number of reallocated sectors and im not sure why, as its a brand new hard disk.


Does anyone know what i can do about this or why its happening?


Heres what the problem is about:
"Count of reallocated sectors. When the hard drive finds a read/write/verification error, it marks this sector as "reallocated" and transfers data to a special reserved area (spare area)."


Thanks

All current HD's are made with many more sectors than their stated capacity, and the HDD unit itself (on its controller board) controls their use. The drive monitors itself and, if it finds trouble in any one sector, it moves (reallocates) all the data to a new good sector and marks the old one as "bad-never use again" or something like that. It also keeps track of this action. Eventually its store of spare sectors gets awfully small and it throws you a warning that it is running out of spare space to do this automatic repair job.

This definitely should NOT happen very soon on a new drive. Check its warranty and talk to the drive manufacturer about replacing it NOW before the warranty expires. Of course, you'll need to arrange to clone your old drive, with all its data and OS, to the replacement drive before it crashes completely.
