Attaching external hd via PCMCIA ?

[Blair Kelly III <blair.kelly@worldnet.att.net>]

Does anyone have experience attaching
an external hard drive via a
SCSI PCMCIA card?

I have a Sony 505F notebook running Debian 2.1.
I would like to backup a very large (1 G)
file that took a large amount of
computer time to generate.  (Minor question-
Is a SCSI card attached to an external
hard drive my best way to go?)

I have been reading the PCMCIA HOW-TO.
I have been considering the ADAPTEC
APA-1460 SlimSCSI card, but have seen
one newsgroup posting where someone said
they had trouble using it to connect to
a hard drive.

Any suggestions would be greatly appreciated.
