Yeah, I think that is actually what I did (using strings to filter out the obvious garbage). I couldn't quite remember which command I ended up using.Heater wrote:Oh yeah, trawling though disk blocks trying to find lost data. Fun, fun fun...
Don't forget the "strings" command. Helps to get the textual data out of a lot of binary gunk. For example:
Code: Select all
$ strings /dev/sdb | less
Decades ago, a PHD student came to me with a problem, his thesis which he had spent 3 years working on, was on a computer - and the hard disk failed! No backups, nothing.
Definitely. Consider the problems if a fire destroyed the building and so on.
The "digital camera" advice - or, really, any method of formatting the SD card back to "normal" (aka, "Factory Default") - is generally given in the context of NOOBS (i.e., PINN), where it is important to format the card properly before putting the software (NOOBS/PINN) on it.Also note that if your card is working properly, it's only you file system(s) that are scrambled, then it is not necessary to format it before writing a new Raspbian or other image to it. That operation does not care about whatever format is on there beforehand.
