The story so far...
- I was experimenting with Unix's dd program on my Ubuntu laptop, trying to find a quick method to wipe a micro SD card securely.
- I set dd in motion, came back a few minutes later, and the whole system had crashed.
- When I try to reboot, I get a screen saying "checking media" and then a notification that the boot has failed.
What I'd like to achieve...
- There's a modicum of data - a couple of GB - that I'd like to recover if at all possible.
- Also, I'd like to be able to use the laptop as before this calamity, but without deleting any data.
More information
- I am able to boot from a USB, but, if I try to re-install Ubuntu, the only option it gives me is to wipe everything on disk at present.
- dd was only running for long enough to wipe, at most, 100 GB of a 1 TB disk. So there must be some recoverable data, right?
