Recover Data from Failing External Hard Drive

I am attempting to recover the data from a failing Seagate external hard drive. I was going to attempt using ddrescue or safecopy. I am currently using Kali. The drive will not mount and the output from dmesg is:

[  657.245471] sd 7:0:0:0: Attached scsi generic sg3 type 0

when I run fdisk -l obviously the device does not show up. I attempted to use safecopy --stage1 /dev/sdc /dev/sdb where sdc is the failing drive as shown in dmesg and sdb is the destination drive. Safecopy fails because it cannot find sdc. Any thoughts on the way forward. Thank you.
