dd and dc3dd failing to exit after files are written[SOLVED]

arti · 2016-04-17 11:51:08

I'm trying to get a fresh install onto a flash drive, I've used both of these programs with 0% success,
dd hangs for hours, dc3dd writes all of the files to the flash drive and then fails to exit.

sudo dd if=bl-Hydrogen-rc2-amd64.iso of=/dev/sdb

doesn't finish

arti@dexperiment:~/iso/Hydrogen-rc2$ sudo dc3dd if=bl-Hydrogen-rc2-amd64.iso of=/dev/sdb

dc3dd 7.2.641 started at 2016-04-17 13:44:23 +0200
compiled options:
command line: dc3dd if=bl-Hydrogen-rc2-amd64.iso of=/dev/sdb
sector size: 512 bytes (assumed)
   875560960 bytes ( 835 M ) copied ( 100% ),    3 s, 260 M/s

At 100% it's not exiting either.
I've tried both programs on both 32 and 64bit systems with two different flash drives without success.

Is anyone else having an issue when burning iso files to USB flash drives on their machines?

Does `cp` or `cat` work?

sudo -i
cp image.iso /dev/sdb ; sync
# or:
cat image.iso > /dev/sdb ; sync
exit

You can also try:

sudo dd if=image.iso of=/dev/sdb conv=noerror,sync

sudo strace dc3dd if=bl-Hydrogen-rc2-amd64.iso of=/dev/sdb 2>trace

and please post the contents of the file 'trace' here (pastebin on paste.debian.org if the file is giant long [it probably is]). When it hangs, also run dmesg and post that output too.

dmesg output looks like systemd-udevd is disagreeing with something..

after removing the USB drive after dd hung for an hour:

1710080+0 records in
1710080+0 records out
875560960 bytes (876 MB) copied, 1848.66 s, 474 kB/s
dd: closing input file ‘bl-Hydrogen-rc2-amd64.iso’: Bad file descriptor

I'll get the strace output up in a sec.

@OP Did you do a checksum on the downloaded iso? Have you tried another download?

The checksums are fine, I've tried it with other .iso files on both of my machines.

The USB session to your stick is getting lost; and there are I/O errors and lost writes. It looks like the flash memory on that stick is corrupt. It's kaputt. You can't trust that thing with any data.

Hmm, exited cleanly with a new USB stick.

I'll try to boot into the image and let you know if it's corrupted.

Boots, just fine.

Good news.

If you could edit the title of your first post and add [SOLVED], if you think it is?
