Junk and unwanted remnants on my hard drive like tmp and system files drive me nuts so I would like to clean my hard drive using a combination of utilities like CCleaner and Defraggler.
In order to understand how the cleaning works, I have a few questions to ask.
In defragmentation, does Defraggler perform a complete transfer of data from one block to another, or does it copy the data from one block to another? I understand that deleting files only deletes the pointer but not the data itself, so I'd like to know if defragmenting behaves the same way. (Is defragmenting going to leave data on the old block and mark it as writable space?)
My next question is, how does Drive Wiper works? I intend to overwrite the free space on my hard drive. I read somewhere on the web that Drive Wiper replaces the data on the free space with all 0's, all 1's or random data. I would like a "factory reset" of the free space on my HD and would Drive Wiper accomplish this?
If I run Recuva after Defragmenting and Wiping, will it still detect the deleted files?
Any other tips on cleaning the hard drive?
