TIA-Is there an easy way to restore files from my second HDD that I deleted by accident? Disk /dev/sdb. I wiped out my Kmymoney data by mistake, and my backup to my thumb drive would still leave me with about an extra hour's work.
I asked how you deleted them because sometimes, if you use a file manager, it simply places your deleted files in some sort of trash folder.
Command line, much harder recovery.
Doesn't matter now, you manually re-created the missing data.
I tried TESTDISK later, which left me with a small nightmare. It found 75 folders with about 100 files/folder worth of recovered files. Then locked them so they couldn't be deleted unless I took ownership, or whatever Linux calls it via the Terminal. SCREW that, I went into my OS backup and did a restore which was a [censored] of a lot easier IMO than trying to take control of all those folders in a terminal and deleting them.
I learned a few good lessons and I'm up and running problem free again!
