I have a toshiba laptop from 2010.
I asked someone to come over to back up my nearly full hard drive but after a serious of unfortunate events I didn't get what I wanted and somehow what happened is my hard drive never got backed up and a new hard drive got put in. After the person left I was very upset because I have no backup of my old hard drive. On the new hard drive there are files from my old hard drive, so the new hard drive is not empty and I don't want anything bad to happen to it. The person did a cloning of my computer but what I had wanted was all my files put on an external hard drive so I could view the files on other computers. The cloning backup was done on an external hard drive that is not mine, so I don't have my own backup on an external hard drive like I wanted.
So here is my question: is it okay to take out my new hard drive and put the old hard drive back in? Then I will have a backup done of the old hard drive onto my own external hard drive--is that okay? And then is it okay to take the old hard drive back out and put the new hard drive back in? Will all that in and out cause damage or problems? Will it cause any sort of file corruptions or for any files to get deleted or go away? I absolutely cannot risk anything bad happening to any of the files on my old hard drive. I am very nervous about putting hard drives in and out so many times. I don't want anything bad to happen. Is it possible for anything bad to happen when taking hard drives in and out of computers? I know hard drives crash so it makes me nervous messing with it. i do not want anything bad to happen to the new or the old hard drives.
The reason I am wanting my old hard drive put back in is to do a backup of it onto my own external hard drive. I do not want to do a backup of the new hard drive because I think I did something to mess it up, it is hard to explain over text.
Please help. Thank you
