performance issues due to corrupted external disk #46

I decrypted an fvde partition and then mounted this partition (to the external USB 3.0 hdd where the raw file is located too).

Then I tried to copy with cp to another folder on the same external hdd (to store data decrypted).

I'm trying to copy about 90GB of files and inspecting the current progress it would take about 3-4 days to copy this.

Any hints on why this is taking so long? Or is it "normal" when using this tool?

this is an experimental project.

I've not seen such behavior before with this tool. I opt you take the time to properly troubleshoot, before you put blame somewhere.

Seems like the external hdd I used was corrupted. I used another one (freshly formatted with the same type of file system) and it copies very fast now :)
