I have a slot for removeable harddrives which I use for backups. Now I put one of my older harddrives into the frame that goes in that slot.
And there the weirdness starts.
First, this drive is extremely slow, much slower than the other removeable harddrive I usually use. But it was my system drive until I got a new bigger one, and it wasn't so slow when I used it as a permanently built-in drive.
And then there is some old data on it, for my backups I want a clean space.
So I opened the management tool (the one where you can assign letters to the harddrive, I don't know the English name), right-clicked the harddrive and chose "Format". It appeared to be working, and I went for lunch.
When I came back, the drive was gone! I mean it was still in the slot and running but not visible in Windows. A reboot brought it back but it hasn't been formatted, the old data is still there.
What's going on here?
