And how big is the dle that fails? Bear in mind the reserve is 100% at
default. Meaning its all reserved for use if the tapeing fails, and will
not be used for temporary holding. You need, for that big a tape, a
holding disk that exceeds the tapes size, and a reserve setting of perhaps
-500megabytes.
For a system like yours, with an 80GB tape, I'd pickup & install a 100GB
hard drive and use that for a holding disk. They're comparable to the
cost of a couple of those tapes I'd guess, certainly less than a $100 bill
at Circuit City these days. Even the slower ones should be able to supply
the tape drive in continuous streaming mode once the write starts. I
don't know the exact exchange rate, but I'd assume thats less than 40
pounds sterling on your side of the pond.
