A customer was having a problem with hers, so I tested one from stock.

I could not get it to mount on a G4 or Mini (OS10.3.9) or a G5 (OS10.4.2), but it did mount on a Creation Station (win).

Marantz TS said it should work, but didn't have a system to test it on. They thought there must be a problem with the PMD671. (although it worked fine on a PC)

The Compact Flash card worked fine in a USB card reader on all the same computers.
