Full 3TB gone to 746gb

Hi all,

I did search a lot before I posted here. I found lots of info on the 746gb issue but not with a full drive.

I dont know if this started tonite or not but in any case.  I plugged my drive into my system tonite and it says about 5gb free out of 746. It still shows the dir for all the files and folders but just about all of them are at 0kb. 

I am really hoping I can get this fixed. I am not sure if it helps but I just got a 6tb duo and had it all hooked up to do a back up but thats when I noticed this issue.  I have tried to plug in my other 3tb drive and its fine. Tried updating the system all fine. Updated the drives fine. Duo is fine.  Checked with a partition program and it shows 3tb, and I can make the 746 bigger to the 3tb (2.6tb abouts) but not sure if I will get the data back or will that make sure its gone. I have also tried rebooting a few times, and redo the mbr through another program.

Need help pls.

Hi, provably the data is corrupted, use a data recovery program like recuva or testdisk and then format the hard drive.
