My 4tb drive somehow lost some of the date. IT was full with 4TB of movies and somehow it started reading only a certain part of the data. I tried to copy whatever data could be coppied to another hd and I only got 1TB, 3tb of data was unreadable.
I formatted the drive (quickformat) and now Disk management only sees it as 3TB.
By the wayI used the Data Lifeguard tests:
Quick test passed
Extended test passed
I checked for bad sectors by a different program ana dthere are none!!
I don’t know what happened to this drive.
Once I get this upto 4TB I will use a recovery program to recover the data.
I also used the DOS utility and did only the Quick Write Zeros, it is still at 3TB
If I connect this drive via a ext SATA dock I see only 1TB
I searched the internet and I saw HDA2 (I think this is manual and I need to enter the size manuıally?? and HDD Capacity Restore tools (doesn’t work on win7 I suppose)
Can someone help?
