I hesitate to call these ``supported'' autochangers because the only autochanger that I have in my possession and am able to test is the HP SureStore DAT40X6. All the other autochangers have been reported to work by Bacula users. Note, in the Capacity/Slot column below, I quote the Compressed capacity per tape (or Slot).
