The hard disk is a Stardom 2611-2S-S1 device: actually two 250GB drives in a RAID0 config managed by the device itself - it should appear to the kernel as one SATA drive. If it matters, the underlying HDs are "Seagate Barracuda 7200 10"s.

I have received word from the vendor that the Stardom 2611 will do RAID0 or 1 under windows, but only RAID1 under Linux. (Their manual said it worked with Linux but failed to mention the RAID mode restriction: argh!) They recommended the 2600 model for RAID0 with Linux, but that model is only SATA-I so I will probably go with alternate hardware. The vendor also suggested the possibility of a firmware upgrade to the 2611 - I am still waiting to hear. I will post a followup if this happens. Thanks all for your help and suggestions!
