Hello all,

Today I was trying to extend one of the partitions on my seagate barracuda 3tb drive. Disk management asked me if I wanted to convert my disk from basic to dynamic, which I accepted. BIG MISTAKE. That failed, and it left my disk showing in disk management as "dynamic invalid". I can't access my data on windows or even a Linux live cd.

After doing some googling I found that by changing some of the values on the disk with a hex editor like HxD (), it would go back to being a basic disk.

After trying this, I realized this method only works on disks that are under 2 tb. I have yet to find a method to fix this on a disk that is above 2 tb. If there is no way to convert it back, is there at least a way to retrieve my data off the disk?

The manual Hex editing you did may make the problem worse. You should only try that as a last resort. Anyway, please download and install Partition Guru Pro Trial from the below link.




It may allow you to view the contents of invalid partitions and copy data from them.
