Hi Folks,

I am trying to run ddrescue on a disk with a few bad sectors. Evidently it
has not encountered them yet as errors is still 0, but ddrescue is going
very slowly:

The data rate is averaging 43000B/S.

I have tried -d - which is an invlid switch.

I have tried -c 64 which didnt seem to help much.

I am currently running it wiht sudo ddrescue -n -c 64 /dev/sdc /storage/test
testlog 

I am also running it from a USB-IDE bridge and imaging to a disk attached to
a PCI SATA controller card with disk attached..not sure if this migh tbe
effecting speed?

Any ideas?

Cheers

-Al
