Disks are empty, that suggests something (or someone) deleted the data, is the server directly exposed to the internet?

Hi JorgeB i use the UFS explorer to recovery 60% the file.

but the root casue is unknow. 

today i want to restart my unraid server i found the u-disk could not boot the system.( boot error)

i use the backup file to the u-disk still error.

i try to switch the u-disk to boot. it successed. 

it seem the u-disk error cause the hard-disk array lost data .

is it possibile?

No, but if something/someone accessed your server and deleted the data they probably also deleted the flash drive contents.

that's understood but i try to use the backup flash file to the u-disk also error.

it obvisouly the flash disk is something wrong.

the final result the some file gone. i just want to know the casue and lesson learn.

Problems with flash drive will not cause data loss in the array unless someone has hacked code onto your flash drive.
