I’ve had CF card problems while connecting with USB to a Mac. Since then I just bought an external CF card reader and I transfer samples like that. I didn’t like that the USB disk mode somehow corrupted my card.
One thing that was never clear to me from the OT manual was the order of operations for USB disk mode – do you connect everything and then power it on? Or do you power it on and then connect USB cables and then put it in USB disk mode? Or some other permutation?
From the manual:
8.5.1 USB DISK MODE
Enables the USB connection. Connect the Octatrack MKII to a computer using a USB cable, select USB
DISK MODE and press [YES] to make the Compact Flash card appear as an external mass storage
device to the computer. When the Octatrack MKII is connected to a computer via USB audio pools can
be filled with content. For more information, please see “7.2.1 ADDING CONTENT TO THE AUDIO POOL”
on page 27.
It’s not very clear on the order of things, so I simply don’t do it
