Re: [vox-tech] ZIP drive woes



insmod load a module, but does not do deps.

You should avoid using insmod unless you know for certain that only one
module is needed.

Try rmmod the ppa module and then after it is removed, try modprobe ppa.
modprobe does mod deps and may solve the problem you are having. (It seems
more like that it will not since it appears your drive has been found, but
it is worth trying.)

Also, see if you can dd the device and see if the drive comes on.
# dd if=/dev/sda of=/dev/zero bs=1024k count=10

If the light comes on, then there is a good chance you are looking at the
disk, and the drive may be ok, but the disk is bad.

Does the drive click-click-click-clik a lot while running?

Also, I do not recall zip being probved as a 1Gb disk drive in the
past. :-/
