I have a external HDD that
- produces random read failures (and it would after that show errors for all subsequent read access until I switch it off/on again)
- S.M.A.R.T information shows that the number of corrupted sectors is increasing (and I should replace the HDD with a new one)
Now my problem is that I want to generate one good RAW image
.img file from this HDD and since my HDD is generating random "read sector failures" I want to find a program that is able to generate partial RAW disk images (that I can concatenate later to one complete good image).
I've tried so far:
Acronis True Image 2017 (commercial version)
- This allows generating images (also split into e.g. 100 GB packages)
- But it won't allow me to stop/continue after a read failure (and a powercycle of the HDD)
- I can just retry (doesn't help) or ignore every "sector read failure" afterwards
- Next time it would start from sector 0 again (so I never get more then the first 30-40% of the disk data)
- It advertises "low-level" copying, but the results were the same as above
Just from looking at command line tools like Linux's
dd or some clones for Windows it's probably doable, but I would prefer something with a GUI on Windows which gives me some sort of visual control/overview of what I'm doing.
Alternatively I'm looking for a tool that does allow to "continue" after a failed disk-imaging at the position of failure (like with a download in my browser after I lost contact with the server).
