My computer has three hard disks: two, 3TB platter drives and one Flash drive with the system on it. For the last month or so, the flash drive has often not been recognized at start-up. Which means the computer couldn't boot since that was the system drive. I'd restart over and over until the flash drive showed up and everything was fine. At first that meant once or twice and we were good to go. As time passed it meant ten then fifty, then 100 times or more. I think it's finally over now, and just plain won't work. I figure I have 2 options:
1) Assume it's the flash drive itself that is the problem. I've tried messing with all of the cables and I'm pretty convinced it's not a cable/connection issue, but that doesn't prove it's the drive. though it seems likely. So I replace the flash drive. The two downsides are that it might not be the flash drive and I don't know how to put the OS on the new drive.
2) Replace the computer. Upside is it's really easy, downside is it's expensive and seems uncessary if it really is the flash drive.
