Hello, pretty sure my USB drive is dead. It was working last night, came back today to find the server off, turned it on and the mobo would post successfully and then nothing else. I'll admit I am not technical at all, but the flash drive does not show up in disk management, or mountvol via the command line. The OS doesn't respond at all when I plug it in.

 

My question is, I have an old backup of the flash drive as well as an old screenshot of the drive positions, can I just copy some or all of the files to a new flash drive? If so which files? Or am I better off doing a fresh install?

Your configuration is completely in the config folder on flash. If you make a new install on a new flash, and copy that config folder from the backup, then you will have the same configuration you had when that backup was made.

 

The most important thing to get correct is the assignment of parity. You don't want to accidentally assign a disk with data on it to the parity slot, or it will get overwritten by parity.

 

Take a look at disk.cfg in that config folder and edit it (plain text) so the array doesn't autostart and you can check things out before starting it up.

 

Also, you will have to do a license transfer to the new flash. That can be handled automatically in Tools - Registration.
