DDrescue Basics Question, Please help!

[bagellad]

Hello, Thanks for your time.

I am trying to recover files, pictures and videos from an external hard drive. Currently I have removed the drive from the enclosure and have it connected with a usb hard drive connector. I have been trying to get ddrescue to work but unfortunately I am not able to have it find the drive. It is shown on the computer screen but not mounted. So Ive been trying to get ddrescue to work with a flash drive just to make sure I have the commands right...

bagellad@ComputerHeroesStation:~$ sudo ddrescue -r 3 "/media/FLASH DISK" Desktop/Backup.img Desktop/logfile.log
[sudo] password for bagellad:


Press Ctrl-C to interrupt
Initial status (read from logfile)
rescued: 0 B, errsize: 16384 B, errors: 32
Current status
rescued: 0 B, errsize: 16384 B, current rate: 0 B/s
ipos: 15872 B, errors: 32, average rate: 0 B/s
opos: 15872 B

but the recovery file is empty. Any ideas what I am doing wrong?

Get rid of the quotes.  Also, you need to image the device, not the mountpoint.

For example, your drive may be /dev/sdc with one partition on it.  So your filesystem will be on /dev/sdc1.  When you plug it in, /dev/sdc1 will be detected and mounted at /media/FLASH.  You don't want to image /media/FLASH, but /dev/sdc1.

Try running

sudo lshw -C disk -short

to get a list of attached disks.  You can also look in /proc/partitions;

cat /proc/partitions

If your drive is failing, it's partitions may not be detected.  All that would apear is /dec/sdc...  You you may have to image the entire thing (/dev/sdc).

So, the command would be
sudo ddrescue /dev/sdc image log

P.S.  Use a log file.  It will allow you to resume if you interrupt the process....
Good luck!
