Well.... In general you get what you pay for... most drives fall in to the
consumer "trash" category, in my opinion.  The only reliable ones I have
seen out of about 15 or so brands I used are

Fuji, CDC, and Maxtor.. in *that* order.


and, yes... fuji does make a st506 interface drive... that would fit
the same place as the Vertex you have [ V185 is it ? ]
