karenjoly :
Luck has nothing to do with it.Its a somewhat common situation arising from cloning and we been doing it here for years. I have never has anyone come back with issues. Have you have actually tried it ? Or can provide details on this supposed confusion you and others will experience " down the road"? Fears like this arose when windows was a floppy disk. Time to learn new tricks perhaps ?
I have seen a few cases of confusion with this.
Guy clones his drive to a new one.
Leaves the old drive still in the system.
Uses the system as normal, completely ignoring the old drive.
Months pass.
Boots up one day, and "What??"
System looks like it did 6 months ago.
Initial thought was a virus, or some weirdness with an OS update.
Maybe somehow it rolled back to an earlier Restore Point.
The system was working perfectly, just "where's all my stuff?!?"
Took us 2 days to figure it out.
It was simply a bad SATA cable.
Upon booting up, the system could not read from the new drive he'd been using, so it dropped down to the next selection in the boot order, and booted right up. The old drive that hadn't been used for 6 months.
He had completely spaced out that it was still in there.
