This is exactly an Arcserve problem.

I am running Arcserve v9.0 (with SP1) on win2k (with SP4). At Arcserve
decive manager I CAN mount and see the 8 DDS4 media in my autoloader. I
right-click on one of them and choose 'Format', and the format pop-up
window apperas.

However, there is no media I can choose from the window. It should list
the 8 media in the magazine and let me choose the media I wanna format

Similar behaviour appears with 'Earse'.

I definitely don't want to re-install the server because of this
problem. I have re-installed Arcserve already.

Please advise.
