IDE Hotswap Disks

[Flameeyes]

Hi,
I've a rack for ide HDDs that claims to be hotswappable, in fact, I'm
able to remove the disk without problems after unmount it.
The problem is when I try to connect it after booting without it. The
only way I have is rebooting (also with warm reboot) the machine, and
then the kernel rescan the bus and see the new drive.
I tried hdparm -R /dev/hdb (i'm using devfs, but also create the block
device 0 64 do nothing), but it gave me "expected hwif_ctrl".
There's a way to rescan the bus without reboot? I need to try with
ide-scsi support?

TIA.
