I am not sure that the code for compression used to get 250Mb is publicly available (judging from past postings for CMS to this group I doubt it). This means that if you want to exchange tapes with DOS you have to use the uncompressed mode. Why don't you get a QIC 150 tape drive. With the newer 6250 tapes it can go up to 250Mb uncompressed. I have the Tandberg 3660 (bought from a liquidator 2 years ago) connected to an Adaptec 1542B and I am very happy with it. When I use it to take backups from my Quantum 1225S (also on the same 1542B) usinf dump(8), the tape streams continuously. **vp ----------------------------------- Vassilis Prevelakis | vp@csi.forth.gr Thoukididou 10A | old style address: Plaka, Athens 105 58 | ...!mcvax!ariadne!vp GREECE | Tel. +30 1 32 32 867 | FAX +30 1 72 24 603
