I was running DBAN on a laptop HDD and I had an external HDD attached. Without realising that, I ran DBAN in auto mode. Completely stupid, I know.
I noticed it was attached when the operation started, and in a panic I pulled the external out of the USB port.
Then I attached it to my other laptop, and Windows knows there's a device plugged in, and what it's called, but didn't show up in My Computer.
So I opened up disk management and added a small 8MB partition. Now it shows up in My Computer but says it needs to be formatted before use. Obviously I don't want to do that. Disk management shows the 8MB partition and 931.47GB unallocated.
It's a ~1TB Western Digital My Passport drive and had around ~250GB free before the... accident.
The drive was plugged in to the DBANning laptop for maybe 5 seconds, it hadn't even reached 1%.
I know I'm an idiot (feel free to remind me) - what, if anything, can I do, save taking it somewhere expensive?
Edit: Just to make sure no one thinks I've run off. I ran EaseUS Partition Recovery yesterday and it returned nothing, but now I'm running EaseUS Data Recovery and it's found a lot of files. It's not complete yet (about 16.5 hours left!) but I'll update then.
