Re: Data recovery
Thank you for the advice! I followed the instructions and got a lot of files back, including the school files for my current semester (I'm a teacher) and the stuff I really can't live without. What I didn't get from my SSD was two sets of files, my txt and org files, which are mostly very small, and my epub files. Both sets of files were stored together, and I suspect they were over-written and are gone for good. The epubs I don't mind, and the txts/org I can live without. Interesting process. Harder to get stuff back from an SSD. I also got a suggestion through the Debian list to use hb4most as a front-end for scalpel and foremost. I'm going to try that in a week or so and see if I can retrieve anything else. Will let you know if I'm successful.

Is this on a spinning-platter HDD, or on one of those new-fangled SSDs? As far as I understand it, you're unlikely to be able to recover any data from an SSD as they're so aggressive about remapping logical/physical blocks. -- "Don't be afraid to ask (λf.((λx.xx) (λr.f(rr." ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
