Thanks Chantelle - 100% au faix with how windows works with drives, and even if it did get re-assigned it's very easy and quick to change it back.

While I appreciate your post, it didn't really answer the question though from the drive use aspect wink

So, to re-phrase, if I leave it plugged in how does it go mechanically with all the stop/starting? Probably really a question about the quality of the hardware more than anything I suppose??

There are times when I do not use BIAB for a week or two, so having it starting, running and stopping every day, sometimes a few times a day (if there are other PC issues or software updating that needs restarts) so, yeah, I feel it is a valid query smile
