the thing is, that I did use fdisk, and no matter what I did, the partition
table wouldnt stay. i then plugged it into a windows machine, and, explorer
crashed, and wouldnt read anything everytime i plugged it in. it found a
new harddrive.
i would add it to just one file but, ... it is fat32 , so no files above 4~
gb
but, it may just work anyway. is there way I can break it up into 2 files?
thanks, martin

I hope that there wasn't anything on the dos partition that you wanted
to keep since it is now toast.
running dd like that did what you told it to do...over writing
the /dev/sda1 partition with a copy of whatever was on /dev/hda1
I suppose issuing the 'mount' command would tell you what was
on /dev/hda1
You probably have no choice but to clean up the usb drive with fdisk...
fdisk /dev/sda
as at least the first partition has been clobbered.
h # help
p # print (though this might be phony since it will read the
partition table and the contents may not match)
Craig
PS...You might have had an easier time of it if you had just done...
dd if=/dev/hda1 of=/dev/sda1/backup_device_hda1.dd-file
