Running dd (in Windows DOS-box): "Error opening output file: 5 Access is denied"

[Mark Filipak]

c:\Setup\Debian 6.0.6 64-bit>dd if=debian-live-6.0.6-amd64-gnome-desktop.iso of=I:/

I've tried several differing path specifications for both if and of. Any help?

Thanks - Mark.

if should point to the file, so what you have there should work if that
file is in the current directory. of should have only the disk
identifier, no path ie 'of=I:' You may want to try running the DOS box
as administrator if that is possible and applicable on your version of
Windows.

dd.exe and ISO are in the same directory (folder). I'm logged-in as Administrator.

dd if=debian-live-6.0.6-amd64-gnome-desktop.iso of=I:\ results in "Error opening output file: 3 The system cannot find the path specified"

dd if=debian-live-6.0.6-amd64-gnome-desktop.iso of=I:/ results in "Error opening output file: 5 Access is denied"

dd if=debian-live-6.0.6-amd64-gnome-desktop.iso of=I: results in "read from 95 disk"

dd if=debian-live-6.0.6-amd64-gnome-desktop.iso results in a spectacular crash (DOS-box only, Ctl-C recovers)

This may not be enough. Right click and choose 'Run as Administrator'

where it suggests that error may come from not using the block size
parameter, bs, try 'bs=1M'. There is also some debate over od vs of, I
don't know which is correct.

Thanks Andrew! It worked. The 'dd' command's documentation was wrong.

This worked:

dd bs=1M if=debian-live-6.0.6-amd64-gnome-desktop.iso od=I:

In particular, the 'od=' switch is not documented (I would guess that 'od' means 'output device').

Now that I can/have run Debian-Gnome, I have some studying to do. My first objective is to get WiFi working. Wish me luck, and thanks for your help.

Ciao - Mark.
