IDE-disk spindown fails

Hi.

I have a problem spinning down my Western Digital 80GB harddisk. root@server:~> cat /proc/ide/hdc/model
WDC WD800BB-00CAA1

Neither hdparm -S nor noflushd is able to spin down this disk.

The machine is a very old Pentium 1 machine. It's BIOS doesn't recognize this new (I've bought it a few days ago) harddisk. So I've set this IDE-channel to "none" in the BIOS to avoid very long searches on this channel from BIOS while booting.

Reading and writing on the disk works quite fine.

/dev/hda is the drive, the system is installed on. It's a very old 2GB Quantum drive. root@server:~> cat /proc/ide/hda/model QUANTUM FIREBALL_TM2110A

The BIOS recognizes it and I'm able to spindown it.

Does linux depend on the BIOS when spinning down?

root@server:~> cat /proc/version
Linux version 2.4.21 (mb@lfs) (gcc-Version 3.3.1 20030519 (prerelease)) #2 Son Jun 15 13:08:42 CEST 2003

If you want me to run any tests on the machine, or if you want some information, I've not given, just ask, please.

Sorry, I found out, that it's not a kernel problem. It's a problem with the userspace noflushd daemon.
