Don't you have at least a PC in which you could test your card+disk ?
it may be possible that your card does not work in your alpha, I've already
had problems with some PCI cards in alpha (most probably because of the
drivers, or poorly designed PCI interfaces).

Just for reference, here is what hdparm sees on my maxtor 120GB on my
alpha (integrated ALI controller). Perhaps there's really a problem with
your disk, but it seems rather strange. Generally, IDE disks with bad
identification stop spinning and do not respond to any further command.

If it comes that it's your IDE controller which is wrong, perhaps you would
be interested in trying a SCSI->IDE adapter, which would allow you to turn
your IDE disk into an SCSI-like one and connect it to your motherboard ?

Regards,
Willy
