Hello mailing list! I've had an event which includes modifying some BIOS settings (can't remember which exactly), and testing some OS other than FreeBSD. And I think that the said OS did something malicious to the disk in question because it has been doing it for prolonged period of time, and mentioned disks.. So this was all on same machine, like dual-booting but from another drive. Then when I went back into FreeBSD I noticed an error, `geli attach` doesn't work, I used a /etc/rc.local script for the GELI disk like so: `geli attach -p -k /etc/diskpassword.key /dev/ada0 zpool import zmedia` I get an error message when I try to run the geli command: > geli: Cannot read metadata from /dev/ada0: Invalid argument. I have /var/backupts/ada.eli if that can help.. There's only /dev/ada0, no ada0s1 for example or .eli or whatever.. Also when running `gpart show`, I see 2 disks: xxx GPT (main boot drive) freebsd-boot freebsd-swap freebsd-zfs and ada0 GPT (the drive in problem) -free- (everything) Does this indicate that everything has been lost, like the partitioning table or whatever you call it, like it has been formatted? Did the other evil OS-fucker destroy my disk without saying it would do that? If you can't tell, I'm hesitant to give more information than what's necessary for someone to help me because almost any data can be used to deanonymize someone, but if you do need some information, please feel free to ask. TL;DR: some OS could have wiped some part of a FreeBSD-zfs drive, can you help me conclude wether or not we can somehow save it?
