My main song writing motivation died a few decades ago when I saved all of my work on a new media that was supposed to be "Safe for 30 years!" It was Panasonic's Phase Digitals (PD's). Ever heard of them? Yeah... Exactly. They were one of the new type of optical storage media that was just coming out (think CD on steroids, closer to DVD's which weren't out yet). Unfortunately, my main hard drive died and, when I went to get everything off of my PD backup, I found that the drive was unreadable. I tried to find a service that could salvage anything, but nobody else had a Phase Digital drive and the hard drive was a complete loss too... ?
As mentioned in another thread, my main computer now has over 22 TB's between SSD's and spinners, plus I have Carbonite's top subscription along with a Dropbox (Business) subscription. Add to this an almost-full Google Drive and a rarely used One Drive, and I've got a lot of stuff saved everywhere!
