I am using the Archive Scorpion, with an Emulex MT-02 SCSI->QIC36 controller.
In playing around since the discussion of multiple vs. single block reads, it
does not seem to matter to the hanging problem. The single block reads are sure
slow though.

On the general subject of speed, I am now trying to go to async IO and running
separate processes for the disk and tape operations. I feel like I have just
gazed upon the Medusa. :-)
