Seagate 1,5TB ST31500341AS CC4H looks fine, no errors when writing or reading whole surface.

But when the drive is idle, it does sector reallocation in the first 100MBs, 2 sectors per second till SMART is bad (Reallocated Sector Count).

Anyone has seen this problem before? The space, where the reallocations are done, is fully readable and writeable, with no errors or no delays.

After the reallocations it sure has delays because of the head dodging the "Bad Sectors" and reading the Reallocated Sectors.

What does "reading and writing the whole surface" mean exactly?

Thank you for the reply.

HDTune write zeros + MHDD surface scan (both from 0-1500GB)

I think I "fixed" the drive.

For the one's who wanna know:

Moved G to P-List and now no more reallocations.

And sure, drive is only used for unimportant data anymore.

Well, 2-3 more benchmark tests should tell if good or not.

Good luck
