Connecting A Disk Drive - Black Box BBR64-MADI User Manual

work but all the ones we've tried so far have done. The only criteria that you
need to follow are:
Up to 2TB with USB2 interface
7200rpm or 10,000rpm recommended
Formatted with FAT32 Filing System
USB2 can carry up to 480Mbits/s of data and for recording 64 tracks of
48kHz/24bit the maximum data rate we need is around 80MBits/s so there's
normally plenty of headroom. JoeCo has already tested numerous USB2
drives from Western Digital, Glyph, Seagate, Verbatim, Samsung, Buffalo and
others and found them to work well. We chose the FAT32 filing system
because it is compatible with all major Operating Systems and it's also the
format chosen for the AES31 digital interchange standard.
However, USB powered drives (such as the Western Digital Passport series)
typically draw more current than the USB2 specification allows (limited to
500mA) and can therefore not be used without providing a separate power
supply. Most standard Flash RAM drives (aka Pen Drives) are not fast enough
to take the full USB2 data rates that the BBR requires and even the 200X
flash drives are too slow for recording 64 channels of 48k MADI data. If you
are not sure, ask the supplier if you can try the drive with the BBR before you
buy it. You must make sure that the drive you are using is fast enough and
not too fragmented before you use it with the BlackBox Recorder. If in
doubt, reformat the drive and make a test recording of an hour or so to be
sure. Then reformat the drive again before recording the performance.
Drives are very cheap nowadays so we advise keeping a few spares around
just in case.

Connecting a disk drive

Plug the disk drive into the USB2 socket on the back of the BlackBox unit and
then power up the drive. The drive will be scanned, logged and ready to use
in a matter of seconds. If it takes more than 20 seconds to log the drive or
the BlackBox reports "WRONG DISK FORMAT", check that the disk is
