Hi,

my recent IBM SCSI drive (18GB IC35L018UWD210-0) connected
to an old Adaptec AHA-2940 UW adapter make as very
irritating high pitched noise (as if it were parking/unparking
his heads?) periodically with the following intervals:

1min35
2min12
5min03
2min14
1min02
4min09
4min14
3min18
1min06
1min04

It runs in ext3, journalling has commit interval set to 5sec.

Does something happen in the kernel with a about 1min05 interval?

Is there some way to keep it busy?

My kernel is 2.4.7-10

Thanks for any reply to this strange request ;-)
