Since my Wedge HD crashed on me yesterday, I was forced to call RSI systems
and see what they can do about it. It turns out that I am basically screwed,
but this is not the point of this posting.

RSI has indicated that they didn't understand the MaxTransfer parameter, thus
the earlier setups all had a recommended MaxTransfer = 255. Now that they 
realized their error, they recommend that MaxTransfer be set to 128000.
According to DiskPerf, my newly restored Wedge drive just gained over 50% 
in performance rate. (I'm not too certain exactly how much improvement, but
I do know it's over 50%.) 

On a side note. Can anyone recommend a HD Backup program ? (PD or Commercial)
I have PD access to SDBackup, Backer (Orange), Backup (DM), MRBackup.
