Default drive mounting ddrescue

hey folks,

I've got a quick question about running ddrescue, does the source drive have to be mounted? Ubuntu labels the drive as /dev/sdc/ but i cannot mount the windows partition or either of the other two partitions on the disc. Will ddrescue be able to copy the whole disc?

kind regards

No it doesn't have to mount a drive to be able to use it (necessarily). If you wanted to do A direct disk-to-disk clone then you can use the syntax
ddrescue /dev/sda /dev/sdb
- that will copy the disk at sda to the disk at sdb; neither needs to be mounted. If you wanted to do a disk to image clone (I believe you can do this in ddrescue) then you can use the following commands to copy /dev/sda to a file on /dev/sdb:

mkdir /mnt/sdb1

Mount /dev/sdb1 /mnt/sdb1

Ddrescue /dev/sda /mnt/sdb1/clonedimage.img
That will make a directory to mount the first partition on /dev/sdb in the /mnt directory, mount the partition at /dev/sdb1 to /mnt/sdb1, and then clone /dev/sda (entire disk) to a file in the mounted file system of /mnt/sdb1. When you're finished you should use the following command to unmount the file system to prevent data loss:
umount /mnt/sdb1
(point that to whatever mount point you mounted to earlier).

If you want anymore help just ask
