The bug where after being on for 24-36 hours, the second hard drive on my #framework 16 laptop just...disappears...is getting really, really old. I thought it was temperature, so I started logging that. But nope. It's not an issue with the flash, because the data always comes back just fine, and there are no read errors or anything. It just gets tired after a day and decides to go for a nap. This is the problem with a fully repairable laptop: I installed it, so whatever's wrong, it's now my problem. I can't just go bother Del or whomever. It's running #Windows 11 because screen readers on Linux are still terrible, so anyone suggesting "install Linux" as the answer gets blocked. But I really don't think it's a Windows thing; it's not in device manager, or anywhere. Only fully powering down the machine and turning it back on again helps. A restart isn't enough. So it has to be a hardware thing!
