Subject: HD CMOS parameters trouble - disk decaying

Lately, the C drive (boot) on my 138M Seagate harddisk got lots of bad
sectors, and it just gets worse. However, the D, and E drive (logical
partitions) on the same disk are fine.

It seems like the CMOS parameters for the C-drive has been corrupted
(check MSD-report below).
MSD reports the drive to have 65313 Cylinders and 255 Heads.
How can I correct these settings. The settings in the bios setup
screen are all fine, so there must be some other way to correct 
CMOS Fixed Disk Parameters.

Here' the MSD-report of my system:
