As Mark says, the 2 TB version will be 2x1TB disks - I've got the 1TB Pro Edition II which also contains two drives (500Gb ea) but the case is not a "throw-away" and the manual gives you instructions on replacing a drive.
Also it came with the software: > My Book RAID Manager for Mac > My Book RAID Manager is a tool designed to help you easily manage your RAID > system, including changing the RAID configuration and formatting the device. Instructions say: > Configuring RAID > My Book Pro Edition II is preformatted for HFS+ (Journaled) and is > preconfigured for RAID 0 (Striped) mode for maximum capacity and accelerated > performance. > This product also supports RAID 1 (Mirrored) mode for data > protection which dedicates half the capacity to mirror the data in both > drives A and B. I'm not sure if it would be possible to configure them as just two separate disks (JBOD) - others on the list may be able to advise here. One minor annoyance I've noticed is that although the drive only fires up the fan when required, and goes into standby mode when unmounted, if you put your mac to sleep then when you waken it up this seems to throw out this system and after a time the fan seems to fire up even when the drive isn't being used. Since I'm not real keen on keep plugging/unplugging the power, my workaround at present is to re-mount the disk with disk utility then eject it with finder - which seems to shut it up (until the next time I sleep & wake my mac). This works fine but is a bit of a nuisance. Suggestions for a more elegant fix welcomed :) Cheers Neil -- Neil R.
