Checking Contents of Unknown Disks

I have some SCSI disks with unknown contents which I would like to check before overwriting them. I don't even know what OS they were used with. The only systems I have to hand with SCSI are MicroVAXen, so I can check them for VMS format without issue. However, for the ones that are not VMS format I would need a way to find out what format they are. I was wondering if there is any VMS software for reading FAT disks (as that is a pretty likely format). According to Hoff (http://www.hoffmanlabs.org/vmsfaq/vmsfaq_012.html) there is VMS freeware that will read FAT diskettes, I am not sure if it will read hard disks too. Trouble is I don't seem to have that version of the Freeware, does anyone have version 6 and the WINFX software? Another way would be to use a PC SCSI adapter. I don't have one yet, but I think I will get one. I like the look of the Adaptec 2940AU.
