You may be able to recover the download ... but you have to make sure you
do it from the image you started with ;)
You have a partial file on your hard drive, and know approx. how much of
you you need to trim off the end to make it "ok"....
you could do something like this:
/backup/cdwork (/dev/pts/2) dwild@argo> ls -l mandrake70.iso
-rw------- 1 dwild adm 327155712 Jan 16 22:06 mandrake70.iso
/backup/cdwork (/dev/pts/2) dwild@argo> du -m mandrake70.iso
312
/backup/cdwork (/dev/pts/2) dwild@argo> dd if=mandrake70.iso \
of=recovered_mandrake70.iso bs=1M count=310
^^^^^^^^^^^^^^
This would take the first 310MB of the file mandrake70.iso and save it in
recovered_mandrake70.iso ... if you had continued the wrong file for 30s
you probably didn't get more than 100-200k or so...but to be on the safe
side trim 2m off what "du -m" tells you (du always "rounds" up ..
well it doesn't really round, see the man page if you want to know what
it's really doing =) ) Remember to rename your original so you have a
backup copy, then rename your new file (recovered_mandrake70.iso) to
the real name. You should then be able to resume your download and have a
valid CD image when you're done....check the "md5sum" output when you're
done to make sure. Also make sure you're getting the same copy of the iso
or you'll waste your time.
-dws
PS I tested this using dd version 4.0 (dd --version) and ncftp -- picked
"resume" after trimming a 1008k file to 950k. md5sum, diff, and gunzip -t
all showed the trimmed then resumed file to be error-free. welcome to the
wonders of linux black magic ;)
