So I do a bsy fix on another drive and everything seemed fine.
The drive showed up and I can see the files.
The problem is it showed up with one partition...the large one ~690Gb.
Now..this drive is from a system and they usually have a second small partition for backup.
So I run testdisk and it finds both partitions. I do a 'write' partition table.
Now both partitions show up and get drive letters assigned.
The small 10Gb partition I can navigate through no problem, but the big partition is inaccessible and shows up as RAW in computer management.
Before the partition table 'write' I could navigate through the large partition no problem. I did not backup the partition table before doing the write.
Any ideas how to get the large partition to work again?
