Hello Folks!!  1st Timer,     

 

Was just wanting to ask a 2pt question thats bugging me?   When wiping the free space on a Hard Drive Does That wipe The Memory too?

ie, If i have a 100gb HD and 60gb is used and 40gb available and then i use one of the various progs which wipe free space - Will that -

1) Wipe That 40gb from existence?  i assume not or

 

2) (wording this bit is tricky)  After wiping say i delete 50gb of stuff from The HD then would i have 90gb available to me?.(the deleted 50+the original unused 40)

Free space on a hard drive can still contain the data that was previously stored there. "Wiping" free space simply overwrites this content (reverting it to zeros or other random content), so the data cannot be recovered. It doesn't make any alteration to the available storage capacity on the drive.

 

If you wipe free space, then delete more content, the total of previous free and deleted space will become available as free space. The content you just deleted could be recovered if the free space is not wiped again.
