[Bug-ddrescue] Problem using ddrescue

[Tim Johnson]

I am using ddrescue v 1.17 to try and recover a disk that seems to have 
had its partition table corrupted.

The disk is a 1T Seagate s/n NA4AHSB6 usb 3.0

I have tried running ddrescue to copy the disk onto a backup, both 
disk-to-disk and  disk-to-image, but it fails to do anything.  I can see 
the device with the command "ls /dev/sdb" ( confirmed by dmesg) but it 
does not appear in fdisk

I have run:

ddrescue -v -v -v -v -f -n /dev/sdb /dev/sdc 
/home/timj/Desktop/ddrescue.log:  no messages, no logfile created and ps 
-ax reports no time spent running ddrescue

ddrescue -v -v -v -v -f -n /dev/sdb /dev/sdc 
/media/timj/iomega/seagate.img 
/home/timj/Desktop/ddrescue.log/ddrescue.log: no messages, no image 
file, no logfile created and ps -ax reports no time spent running ddrescue


ddrescue -v -v -v -v -f -n -R  /dev/sdb /dev/sdc 
/media/timj/iomega/seagate.img 
/home/timj/Desktop/ddrescue.log/ddrescue.log: no messages, no image 
file, no logfile created and ps -ax reports no time spent running ddrescue

Any advice or is the disk long gone?
