Will using a new USB mean I lose all my data?

[jjackstar]

Hi all,

My server is spitting out an error saying "failed to load ldlinux.c32" and thus the system wont continue the boot process. After doing some digging around people have been saying to reformat the USB. Will the new image that is on the USB just detect the array or will I have to reformat the whole thing thus losing all my data? Im not too fussed about losing all of the plugins and VM's that were on the system but I need that data! 

Unraid 6.3.5

Thanks,

Jack

The flash doesn’t really contain any data probably. Just a bunch of configuration files, logs, key, etc. Have you tried running fsck on the flash to repair the file system?

[jjackstar]

I have not tried that, will do so now. Im assuming that you would run that commend after you have logged into the system? It hangs before it gets to that stage.

Take out the flash and run the repair in another machine.

Got the command to work and this is the result:

fsck from util-linux 2.30.1
e2fsck 1.43.5 (04-Aug-2017)
ext2fs_open2: Bad magic number in super-block
fsck.ext2: Superblock invalid, trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/sdd1

The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem.  If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>
 or
    e2fsck -b 32768 <device>
 

The OS still wont boot

Got it back using another command that was found googleing 'how to repair usb stick ubuntu' sorry I don't have the command handy, its on another system. the only issue now is that the web GUI is not showing on the network and booting into the OS GUI mode shows a Firefox window saying that it is unable to connect to the local host.
