RE: Re: Kieran's comments was Last Night in London?

Kieran

these are unused hot swap drives I think...they are seagate cheetahs with a
vented metal plate on the bottom and a plastic/metall sort of holder with
the sun logo and a metal plate on the front which flics out when you push a
plastic thumbswitch type thing.

model number is ST39102fc.

If I were to flog em on ebay how much should I be looking for ?(I have a
pair of them)

Point taken about scsi I use it extensively already :)

Thanks
Mick
