Secondly it is find rather more than I expected and there are a lot of symbols appearing before and after some of the lines.

Can somebody please explain to me what they mean.
Thank You.
I won't do the guesswork and calculation for you. Post the sustained read speed of your secret drive here. Then translate the figures "two days","18%" and "6TB" into an average read speed in terms of "MByte/second" and post it as well.deadmort wrote: 09 Jun 2022, 18:50 This is the first time that I have used Testdisk. I am currently running deep scan to see what can be found. After probably two days it has go through 18% of a 6TB drive. Is this normal for it to take that long?
The symbols that are encapsulated by [] are the names of the supposed partitions found by Testdisk.
