1. Can I boot from a cloned drive?

Yes, you can boot from a cloned drive unless the source disk contains bad sectors or the cloning program executed an incomplete clone.

2. Is cloning bad for SSD?

First and foremost, cloning is not a bad thing:) in most cases, it is extremely beneficial and convenient. But you should bear in mind that cloning gives you exact replica of your system and if the present system installation currently has flaws, you'll encounter the same problems after shifting to a new disk.


When copying data, disk clone software will usually format the target drive. So, before starting the disk clone, make sure there is no useful data on the target drive. But if you've ever lost data after cloning, use Tenorshare 4DDiG Data Recovery to recover any lost data from it.
