I just wondered if someone could shed some light on this.
I have a sandisk extreme, formatted NTFS. From windows 7, if II run check disk by itself, no problem. If I run it with "automatically fix file system errors" checked then it hangs past a certain point.
My first thought was, it got corrupted. So reformatted, with NO FILES on it, same behavior.
On a different computer, same behavior.
If I reformat it exfat, then no problem.
I recently got a samsung shield t7. Brand new, out of the box, same behavior.
I am rather puzzled.
Everything I have read said NTFS should not be a problem on an external SSD. I am at a loss. Perhaps the solution is simply to use exfat (which is what I did on the T7)
I thought about a virus, but according to every test I can run there is none.

The drive doesn't exist in a vacuum. It's in an external enclosure behind a bridge chip that then communicates over USB to a USB device on the host and then a USB driver that then is processed by the CPU and memory and files transferred to wherever.

What is "automatically fix file system errors"? Is that chkdsk /F?
Have you tried taking out the drive(s), connecting it to a computer and seeing if the same issue exists?
Have you tried taking out the drive(s), connecting it to a computer and running the drive manufacturer diagnostics tools?
Have you look at the SMART data? (smartctl -a /dev/whatever on Linux)
Have you tried chkdsk /R?
