- Well I think I have a 35480A tape ...
-
- Hmmm at first the tape has a 1 megabyte buffer ... so when data is in it he
- writes and when not he stops ... so ?
-
- I'm using SIXTUS (IBM/PC) ... sometimes the tapes stops for a few seconds ...
- especialy when he is backing up the 1000 ANSI's , AVT's of my BBS. So I
- suppose the buffer gets slowly full because of the many opening / closing and
- the little files (100 .. 2000 bytes)
-
- So I don't realy know why the tape would lose data when no data is available.
- May be it's only some bytes per stop ? ... bwa ... I measure the capacity by
- looking at the DAT-tape itself ... still I'm not worrying because a tape costs
- 20$ so who cares ?
