- have u tried formatting the disks before and then setting vault to
- `don't format'? i'm not sure about high density but for those `strange'
- 10 sector formats etc that worked just fine... only thing is it didn't
- like 1 sector per cluster if i remember right. (if you need a good
- formatter program, try a recent version of PumpUp from Claus Brod.)

- well the _fastest_ backup program i know still is tar. so if you're
- not afraid of CLIs, try GNU tar (on a.a)...but do read the docs first.
- (this is `the' general archiver on un*x, works on files, tapes,
- disks...everything you have a driver for. the key to speed on floppies
- is to increase the block factor (-b), only problem is it has to be a
- factor of the disk size, ie no._blocks / block_factor must be an
- integer or else multivolume archives (more data than fits on one disk,
- -M) don't work. at least this was so with an older version, don't know
- about the latest.)
-
- remember, be sure you get GNU tar, all other atari tars i have seen
- are a joke at best...
-
- ah, one other thing: if you want to exchange tarred floppies with un*x
- boxes then you need a `raw' floppy driver like ps0.zoo in a.a's mint
- directory (needs MiNT). if that is not an issue you can just write
- files, then you only lose a few blocks. (ie tar cfvb a:/something.tar ...
- instead of tar cfvb /dev/something ...)
-
- and, cause that just happened to me: beware of bootsector viruses,
- the `bootsector' on raw tarred floppies is the tar header of the first
- file! (at least then tar still gets the other files out, unlike other
- archivers...)
