Re: [PLUG] Problem with USB Flash Disk
|
Thanks for this hint - however, I think the floppy module insertion
error is misleading, either to you or the kernel. The machine I'm
working on is a centrino laptop - it doesn't have any floppy drive. I
see that error come up on bootup and shutdown - regardless of whether
the usb drive is plugged in.
However, the lack of floppy could be causing the issue - if I boot with
the USB drive plugged in I get an error as if there is a floppy disk
with an unbootable disk inserted - I need to remove the USB drive and
retry.
So I will explore more - but thanks for taking the time to review my
post.
