Default data on disk gone after defrag

After doing a routine defrag today on a back up drive, I restarted my computer and when I went back to the disk management utility, that particular partition I just defraged was showing up as raw and no file table associated with it. So I rebooted a second time and Windows did an automated scan on that drive and proceeded to boot up. I went back into the disk management utility and now I have a NTFS formatted partition that is empty (300+ gigs of data gone). Anyone ever seen anything like this before? The hard drive I have is fairly new and it passed all the SMART tests.

i've never seen anything like that. I'd be concerned that the drive is going bad though.

check event viewer see if you can find out what the autochkdsk did.

I would download the disk diag software from the manufacturer's website and rn their tests on the drive.

Is the drive still under warranty?

It should be. The drive is not that old. Like under 6 months. I used diskgenius and it seemed to have recovered it.
