Hi. I have the same problem, always getting ideas & writing them down, but after 40+ years of ideas I still end up writing them down.
Someday I'll have the time to put them all into a database, or document file.
But I'll prob'ly end up just finding all the notes & scanning them into pictures with My all-in-one for future use.This way I can sort them into specific categories then just scan them into appropriate folders on the computer.
When I DO enter all that data into a system, I will definitely use an external USB drive, a CD burned copy (20 cents a blank disc when You buy a 100 pack), & prob'ly keep a printed copy of all the text / written files once every 3-4 months (printing the new stuff only after the main files done originally.
I'd be using an organizing system including the date of each item added to the file, saving to both the harddrive & USB drives once a month, & the printings of course.
As ar as the drive recovery ... I bought My first ever 2Tb internal harddrive back around the year 2005 with a quick pileof cash I happened into by a lucky lottery week.
The drive actually physically died unfortunately,by fizzling & with a loud crackle-pop. The drive had a small resistor /transistor / device on it that had physically burned out, with a very stinky puff of smoke.
This drive has never been recovered but basically has most of My early learning of computers on it,& a lot of files recovered from systems I repaired back in those days ... Company and personal systems I actually owned are theones I wanna get back- but I'm pretty sure it'll involve a lab with a "clean room" taking the drive apart &/or replacing or bypassing that particular part.
