There is no data recovery from Secure Erase. The Secure Erase command built in to the ATA standard overwrites every track on the disk - including bad blocks, the data left at the end of partly overwritten blocks, directories, everything. That's what 'file recovery' programs look for: data in blocks that the directory says aren't in use. Your data is still there, even though the OS can't see it. All that delete does is erase file's reference information in the disk directory, marking the blocks as free for reuse. Secure eraseĭelete doesn't delete your data. But there's an easy workaround for SSDs: encrypt, reformat, and re-encrypt, which is described below. As a result the Mac's 'Secure Empty Trash' command has been removed because it can't be sure that the data is actually gone. Thanks to the Flash Translation Layer (FTL) your OS doesn't know where the data is physically. SSDs - now the standard in Ultrabooks and Macs - are a little different. Here's how to decide which one is right for you. Free and cheap personal and small business cloud storage is everywhere.
