Read Errors on USB Drive

[Mark Phillips]

I think you mean ddrescue? I have been running it for a few days and
getting lots of errors.

GNU ddrescue 1.17
Press Ctrl-C to interrupt
rescued:   328577 MB,  errsize:  85901 MB,  current rate:   12047 kB/s
   ipos:   414478 MB,   errors:     321,    average rate:    6771 kB/s
   opos:   414478 MB,    time since last successful read:       0 s
Copying non-tried blocks...

Any suggestions on how to cool the usb drive with the errors. I have it
flat on a cold large faux granite desk surface which is very cold to the
touch. But the drive is still very warm.

Thanks!

Mark
