Yup - reason seems to be obvious . . . if the destination is smaller than the source the liquid overflows . . . so not really a limitation but a reality . . .
Worst case if it had failed I would have just switched back to the original HDD and tried again. There was no chance of data loss as it never deleted anything from the HDD.
That software I used didn't do a bit copy it only copies actual used data size, probably why it had to read all the files and hence took so long. As long as the used size is less than the new SSD size it was happy. It also copied the 2 hidden recovery partitions too.l
OK this may sound a noob question but not having installed an SSD before I need some reassurance I haven't wasted my money.
I purchased an SSD kit (a 500GB + all cables + carrier)
My used space on my current system drive is only ~360GB.
The SSD will be in addition to the existing drive.
Now the actual question
Do I just clone the existing drive (C) onto the SSD after it's been fitted and formatted, then change the boot disk in bios?
