scsi-errors: wrong free-blocks -count, need help, please

[Peter Berlau <pberlau@muenster.de>]

Hi,

to X-mas I got me a new ibm-scsi-drive :)
therefore I have a Adaptec 2940 AU Controller
and, unfortanelety, the drives for this 
(65 pin) ?  are outsold. 
So I buy a IBM 4,5 GB UW
trapezoid connector looks
(            )
 \-----------/
is smaller, than the Drive - Connectors i usualy have,
so i got a "gender-changer"
and can connect the drive, ok
But as I tried to make a filesystem
mkfs -V /dev/sdc/sd5  for example
the scsi timed out and the sytem hangs,
there where no change to reboot so I hard-reset the
box.
slow down the datatransfer rate rom 10m  to 08m in the
scsi-apapter-config for id3 == /dev/sdc 
and restart, became some messages
/dev/sda11 needs check ,,,   (/var)
/dev/sdb5  needs check ,,,,  (/usr)

[..]
Can I "repair" the filesystem, or will it repair itself during several
reboots with fsck
or what must I do, ???

Please help,
thank You very much

Good X-mas
Good 1999
