Doing a level-8 restore from 6 tapes (3 x DC6250 + 1 x DC6150 for the level 0, 1 x DC6250 + 1 x DC6150 for the level 8) was indeed a little messy... > What is the scoop on TR-4 drives such as the HP T4000 and Seagate > T8000? I wouldn't trust them much. The SCSI errors i've seen from those Travan tapes were suggesting a very lousy SCSI implementation. They've even omitted SCSI commands that are clearly marked being mandatory by the standard, let alone the usual optional commands most drives do actually implement. > What is it about DAT or 8MM drives of similar capacity > and read/write speed (on the spec sheet at least) that makes them > cost about 50% more? Ask the question the other way round: why are thos Travan tapes that cheap if proven good mechanics still costs an arm and a leg? The only answer i can think of is that this is just throwaway-ware, not designed to survive forever. Today's DAT drives often last only about a year or two when being in daily use. Go figure how long a Travan tape might do it... -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
