The SATA DVD drive shows as (sr0). there is an icon for (hdb), but tells me "could not mount drive".

Can anyone help me get to the point I can access the second partition of the SATA's to save my data before potentially destructive recovery efforts?? - thanks - gred
You're not going to like this, but you're screwed. That RAID system is almost certainly a software based RAID system that depends on special drivers running on the computer. Those drivers likely exist for windows only, and your RAID system can't be accessed without them (although you seem to be able to access the first drive, likely any large file you find there will be badly fragmented). There are RAID software solutions available for Linux also, but they don't read Windows RAID systems.
