Hello, I've got two little 10GB hdd's left over. Right now, I have a single 500GB SATA HDD I have three partitions, one for storage (irrelevant), one for windows, and one for Linux. I am currently using GRUB. I am wondering if it is safe for me to remove the 500GB hdd, install a 10GB hdd with an os, and then switch them back later. I'd like to play around with my 10GB hdd, but I don't want to re-partition, nor do I really have a ton of space left. I think it would be nice to take my 500GB out, put the 10GB in, and play around with different Linux distros and stuff. So will that cause problems?
