This is NOT a v.2 of this tool, not a new release even, but same utility and driver as before. Check comments on www.xlr8yourmac.com as many saw trouble after using, slow disk I/O.

This came out a month ago.

SCSI : UL4D, UL4S, UL3D(33 and 66MHz Versions), UL3S(33 and 66MHz versions), DC, PSC. NOT just the UL4S/D

Also, from the ATTO README "* ATTO requires Mac OS X version 10.2.4 (or later)." There was a typo in the listing,

Mac OS X 10.1.4 or later"
