Ah, ok, thanks.
I shall make some notes on what actually happens and get back to you, busy few days ahead.
I am trying to remember when I noticed it. Could have been ages. But I suspect in the last month or two.
In the last month or two I have added ram and moved all my drives about.
As in I use Linux Mint as my main, with windows on a separate drive.
Windows WAS on my SSD so i did a few changes about and fresh installs.
I also did backups to HDD before I wiped them.
But earlier in the year, I changed most stuff.
Got a new Motherboard and cpu, psu, then a new case.... then bought an SSD, and moved over to Linux.
But I think it happened in the recent mucking about with the drive changes. Well, about that time, anyway.
