ddrescue won't start cloning a raw drive on an enclosure

[jakegon]

Hi All,

A total noob here. So my hard drive crashed, and I wanted to make an image from it. I used ddrescue for this job. At first it went well but after a while we had a power outage forcing me to turn off my PC.

When I decided to resume the recovery, ddrescue won't start anymore. I can see the drive unmounted but ddrescue just won't run.

I tried doing the cloning in a different distro of linux but still no success. I'm feeling like linux is doing something on the drive that ddrescue can't have access on it.

Question: Is there a command that I can run before I run ddrescue to free up or kill any and all processes that is accessing the drive?

As an addedd info, the drive is now raw and is currently attached to a USB3 enclosure.

Your help will be very much appreciated. Please. Thanks.

In addition to ddrescue not getting access, even gparted or any other apps can't access the usb drive although i can see the raw drive displayed in Disks app and shown as not mounted. Thus, I think the problem lies on an app trying to access the usb drive which in effect blocks any other apps access to it.

Please, I really need help on this one. Thanks.

hi jake,

bit thin on detail there dude...

just to start by saying the fewer translations between a source drive and system the better.
For instance always use native cables if possible, ie sata drive connect via sata, not USB enclosure.

"my drive crashed" ...symptoms?

"I _*used*_ ddrescue" ... what did you type explicitly? ie ddrescue [options] infile outfile [mapfile/log]

"we had a power outage forcing me to turn off my PC."
The power outage turned off your PC or you had a UPS running from which you made a graceful shutdown manually?

What other commands, if any, did you issue to interact with the drive?
How are you identifying which drives are where? ... /dev/sdX (source drive / destination drive)

"ddrescue wont start anymore" .... like what? you type in ddrescue [...] and it does what... nothing at all? just no output or ..?
are you using a mapfile?

Which drives were / were not mounted at all when you started?
ie
I'm using the 320GB source drive and it's on /dev/sdX with a 500GB destination on /dev/sdY and attempting a full disk to disk copy (and so on).

as ever, if the data on there are valuable don't mess around and take the chance of making things worse. Check in with a local data recovery company (not a PC repair shop).
If it's outside your means financially, or you just want to have a go, then fair play. Just be aware you can lose it all in short order.
