need help restoring 6.6.1

I've had an unRAID 6.6.1 server running without intervention for years, but the USB drive just died on me. After confirming the old drive was physically dead, I set about trying to restore to a new but identical USB drive.


My backup is just a folder I copied over from the /FLASH share using Windows. But I can't figure out how to get that properly restored. The machine either doesn't recognize the boot device or I get a Linux boot error.


I've tried the following:

  • format USB FAT32, label UNRAID, copied the contents of /FLASH over and ran make_bootable.bat which reported success
  • zipped the folder and used Unraid.USB.Creator.Win32-2.1 to "restore" it
  • used Unraid.USB.Creator.Win32-2.1 to install the current stable build and just copied my /config folder over afterward
  • manually installed the current stable build and copied my /config folder
  • wondering if the current build might be somehow too new/incompatible (my server probably predates UEFI), tried to track down an actual 6.6.1 installer but had no luck with that


Nothing has changed on the server which was working fine until the USB flash drive died. All the other drives look fine. How do I get my old 6.6.1 configuration restored and activated? I searched here, reddit, and Google, and haven't had any luck so thought I'd send out an SOS. Thanks for any help.

try with a different one


That did the trick! Didn't occur to me that my new USB may also be bad, but third time's the charm! It worked immediately with my first method of simply copying over my backup and running make_bootable.bat. Whew!


Thanks for the help!
