If I have 285 gig used space on my hard drive and 1.75 gig free space. Is that enough free space to do a backup onto an external hard drive?


I understand the computer needs to store information about the backup so there needs to be enough free space to do a backup. Is 1.75 gig enough free space?


When I had a cloning of my hard drive done there was about the same amount of free space and then it went down to 400mb after the cloning was done. When my computer got turned off then back on, I had 1.75 gig free space again.


I posted a question here: http://www.bleepingcomputer.com/forums/t/579169/can-taking-hard-drives-in-and-out-cause-problems/ But now this is my follow up question.


I might be putting my old hard drive back into my laptop and doing a backup onto an external hard drive. Or I might be using an external case thing and putting my hard drive into that and copying all the files from my old hard drive onto an external hard drive. So I am wondering if I have enough free space to do either of those things.


(When I say "I" I mean me and the person who will be over later to help me.)


Thank you :)

I have a toshiba laptop from 2010, if that makes a difference. The hard drive I have is whatever hard drive came with the laptop.

You should have at least 25GB of free space for the computer to run normally. 1.75GB is too small. For backing up you should have at least a 500GB hard drive, 1TB being better.


In the search box type RUN. In the Run box type %temp% then press okay. You can delete anything in the temp directory. Do this for every user account on the computer. Then if you do not have it run Ccleaner and run the temp file cleaner but not the registry cleaner. Download the Portable version here. Make sure you uncheck any optional software offered.


After getting your 25GB of free space do a Disk Defrag by typing Disk Defragmenter in the search box.
