[FW] Results of TESTING with Firewire on External Enclosure with serial ata drive

[Larry Blodgett]

I have attached a summary of the testing I did with the firewire/usb 
enclosure and SATA drive.
This is the results of several discussions yesterday on this list.
By the way these are all Maxtor drives.

> Basic problem
> The enclosure (Addonics Model AE5SACSUF) with the Addonics SATA to IDE

> G4 1GHZ machine

> Testing WITHOUT SATA to IDE adapter.  (tested 3 different sizes 80g,
