As long as the cleaning cartridge has a ratchet to keep tape from being re-used, it'll work fine, regardless of brand. Of course, the "product experts" are a bit biased in favor of the ones they sell. > At least Tandem supports only DDS drives.

If you stick to the most generic SCSI tape commands, nearly anything will work. But if you want control of compression, etc., you want a driver that understands what can be done with the medium and the drive. This is true of DDS, too, if you want to use some of the niftier random-access features. > You might check the Exabyte web pages, though--you can pick up firmware > upgrades that might solve this problem. Will have to check on this. The older Exabytes used somewhat "dumb" SCSI chipsets, though (even now, there aren't many good ones available for targets). So it may not be possible to keep the drive from ignoring SCSI commands while it's working. --Brett
