does Ccleaner overwrite this area when asked to do so How confident can a user be that deleted e-mails, Word files, etc. Keep in mind that the latter two options take longer to complete, because they are performing the same overwrite task either 3 times or 7 times.

A cipher is a tool that is built into the Windows operating system to prevent disk recovery and free up data from unused disk space. I believe I used CCleaner to empty the recycle bin (for whatever reason) after deleting. Connect the hard drive if it's an external disk, and then select the hard drive from the left side menu.

Erasing Free Space on Hard Drives in Mac OS X This option is not available for flash-memory based SSD models (like those bundled within the MacBook Air, Retina MacBook Pro) because those drives use the TRIM function to quickly remove and recover blocks instead, which has the side effect of automatically preventing file recovery fairly quickly – often within 10 minutes of emptying the Trash. This only works on traditional hard drives of the spinning platter variety, which is typical for MacBook Pro, Mac Mini, and iMac models, and is the case with most external hard drives used for backups. The Mac OS X Disk Utility app provides an ability to erase free space on traditional hard drives, which overwrites vacant disk space on the drive to prevent any potential recovery of deleted files (that is, files that have been removed traditionally, rather than through secure methods). Dont run CCleaners Drive Wiper and Wipe Free Space features if Windows is installed on an SSD.
