[comp.sys.amiga] Express Copy and df1:

nelson@udel.EDU (Mark Nelson) (06/13/89)

Based on the review of hard drive backup programs that appeared in Amiga
Transactor recently, I bought Express Copy.  I'm fairly happy with it.
It is much faster than MrBackup, which I was using.  I've been torture
testing, and it seems almost bullet-proof: I was able to crash it by
fiddling with its priority gadget while doing a backup.

However, it doesn't like my df1:.  I have a 1000, so this is an external
drive.  It's stock Commodore, bought with my Amiga (October 1986).
If I try to do a backup to it with Express Copy with verify, 
I consistently get a verification failure with it.  I've never noticed
any problems with the drive doing anything else--the only time I've
ever had a corrupted floppy is when I pressed the eject button before
the in-use light went out.

So, has anyone else seen a problem like this?  Is it possible that the
drive is on its last legs, but no one but express copy can detect it?
Are there any floppy drive torture tests that I could try?

In case it matters, my set-up is:
	Amiga 1000 w/ 512k
	Spirit board w/ 1.5m (100ns) and clock
	External 3.5" floppy
	C-Ltd SCSI controller w/ 24m drive (I forget the brand)
	AmigaDOS 1.3; SCSIdos 3.0
	Adcom GFP-555 + GFA-535 + Revox Piccolo/Bass for sound output :-)
