I'm having a recurring problem with my harddrive.  I have a Microbotics
Hardframe 2000 controller and a Quantum Pro40S drive.  There are two 
20 Mb partitions on the drive.  Partition DH0: uses cylinders 1 thru
416 and parition DH1: uses cylinders 417 thru 833.  There are 49 blocks
per track, so each parition should have 40866 blocks, ranging from 0 to
40865.  Each partition is using FFS and I'm using WB 1.3.2.
 
The problem occurs only on DH1:.  Whenver I write something to it, I get
a "Disk Corrupt" requester.  When I reboot, the validator complains of
"Key 40866 out of range."  Why does AmigaDOS try to write to a block that
doesn't exist?  Now, if I use FixDisk, it complains that block 40866 has
an invalid header.  Of course it does!  There is no block 40866!  If I
get fixdisk to "repair" the header, the disk validates but the problem
recurrs the next time I try to write something to it.  Can anybody offer
any helpful comments or suggestions?
 
Thanks in advance...
