I tried degaussing a tape, but the degaussed tape is not accepted by the=20 taper. The tape is ejected after about 30 s, the Media light flashes,=20 manual says: An inappropriate tape has been loaded into the drive. The tape should automatically eject. Do I need to format the tape? I really doubt that, and how would I be able=20 to do that anyway if the tape is not accepted by the taper? Was it not=20 enough degaussed? Also seems odd, doesn't explain why the taper ejects the=20 tape? Any ideas welcome! Regards, Palle --On l=F6rdag, november 06, 2004 09.18.28 +0000 "Bjoern A.
