I've been reading this group for a few months (plus the FAQ's) and finally
took the Linux plunge (first on a spare parts PC, then I ditched my DOS
I'm DOS CLEAN!!)
My configuration includes a 486DX33 w/AMI bios, 16MB RAM, Future Domain
TMC880 controller, Maxtor 7245 SCSI driver, Conner 162MB IDE,
Sony CDU541 CDROM and a 3com
Everything has gone well on the install even no clock tuning in X386,
except for my SCSI disk drive. When I run "fdisk /dev/sda" it gives me
an impossible number of sectors. It claims the geometry is 4 heads,
1944 cylinders and 72 sectors, which fdisk doesn't like. (It is also
incorrect these settings make the disk out to be 286MB, but it's only
a 245MB). So, I changed the number of sectors manually to 60, which seemed
reasonable. I made a large partition, then rebooted. Upon reboot,
everything looks okay. Then I did "mke2fs /dev/sda1" looked good, until
I got massive numbers of bad sectors. I then rebooted again, and my
partition was gone! So, I tried running "fdisk /dev/sda" again and
fdisk told me that there was a SCSI read error on cylinder 0. I checked
and rechecked the termination, cables (I had a bad one for awhile) and
I/O addresses. There were no problems. I rebooted again, reset heads/
cylinders/sectors and everything was okay again. Ran the mke2fs again,
and it didn't work again (and my disk was thrashed again after the next
reboot). I've also tried a CDC94155 SCSI disk and had similar problems
(but I got NO geometry readings out of it). (My fdisk is 0.93, kernel
is 99pl12 and SLS is 1.03).
Am I missing something really basic? I thought geometries for SCSI really
didn't matter, as long as one made sure it was smaller (or equal) to the
actual disk capacity. I hope I didn't miss a FAQ along the way. I've
got about 10 of them around and couldn't really find much useful.
Thank you for any information.
