OK, having got to this point and with some trepidation, I started fiddling. The removable drive is on ATA channel 1 along with a CD writer. > Is it safe to simply switch the power to the drive off using the keyswitch > and then remove the cassette with the server running but the drive bay > powered down?

So far doing an atacontrol detach 1, powering down the drive with the keyswitch, removing it and doing an atacontrol attach 1 to get my CD back, seems to work without problems. Adding the drive back in, powering it up and then doing an atacontrol reinit 1 also seems to work without problems. Potentially slightly less safe, I guess, simply powering the drive off and doing an atacontrol reinit 1 seems to work. Does anyone have any horror stories or awful warnings before I make this part of my backup procedure?
