OUCH. Don't do this!
I'm not sure why your disklabel got overwritten *in your case*, but there
is stuff that's supposed to be at sector zero, and a disklabel is NOT IT.
Something someday will clobber it. And it did.
Please, back your data up, put either a UEFI or MBR partition table on it,
and then use the rest of the disk for your backup. With modern disk
sizes, the amount of space you "save" isn't worth the first time this
happens to you.

(who went back to look at your dmesg to make sure it wasn't a sparc64 :)
