A degaussed drive has no possibility of being reused so no data will ever be recovered and the device will not function but it can still be recycled for individual parts,” he added. “Alternatively, if a device has sensitive and confidential data stored and the owner does not feel comfortable passing it on to a new user there is the option of degaussing the drive.

But ultimately, it would depend on what your plans are for the device, but with the correct software permanently erasing the data the device is safe to pass on to a new user. So, it is safe to recycle devices if done with the correct software says Kroll Ontrack’s England.

Is it safer to just destroy old machines? It should be clarified, without access to specialized data recovery software, this data would not be accessible through the newly installed OS, for most users.

In cases like this, part of the data might have been overwritten by the new OS files… but there is usually some data left on the drive which can still be accessed with data recovery software,” explained England.

“In the case of both Mac laptops, the data has been wiped by the user, which ultimately means the OS was re-installed on top of the old data no data was deleted or wiped. So then, I asked Mr England (real name, honest)… is it the case that ‘no data is ever deleted or wiped’ in the core of the machine’s memory until it is written over with new or dummy data? For this reason, when Kroll Ontrack receives second hand machines, residual data is still left on the hard drive as the files have been copied over and not wiped,” said Robin England, senior research & development engineer and data recovery expert at Kroll Ontrack. “When most data is deleted from a machine, using a factory restore function or similar, the data is usually simply replaced with original settings as opposed to being permanently deleted. The firm has recently conducted other research suggesting that a deletion attempt is been made on 75% of the drives and 57% of mobiles, but that they still contain data. Kroll Ontracks’s research says that, typically, on second hand machines 35% contained leftover emails, call logs, texts and photos. They thought that I had formatted and reinstalled the operating system (OS) and said that although they could not find any user data in the active data areas, they had managed to recover user data through what they call a ‘signature search’. Had I performed a ‘complete wipe of the volumes’ (or you may prefer the term 'return to factory settings') as I hoped? No, Kroll Ontrack told me. No problem, this is what we do, they said. Would they mind looking at my machines to see how I had done? The firm is a data recovery and ‘ediscovery’ services leader and works with firms to ensure data protection compliance for second-hand mobile devices including tablets, laptops and phones.

Enter your enrolled Apple ID and password.

Opt out of the iOS beta and you’ll stop be notified. This this works for all iOS devices associated with an Apple ID, you can unenroll your account for iOS from either a desktop or mobile browser. It’s just as easy for iOS as OS X, although you accomplish the process entirely from the Unenroll webpage. You can revert to a Time Machine backup that you retained of the previous OS, but you’ll lose all the changes made since, unless you’re working entirely in the cloud: synced calendars, emails, contacts, and files (as with Dropbox, Box, iCloud Drive, Google Drive, and other services). Of course, if you want to roll back to an earlier version of OS X, it’s a much trickier proposition. As with all upgrades, you should certainly make sure you have a clean backup-it won’t erase your Mac, but OS X upgrades can go pear shaped and there’s no reason to slack on making sure you can revert to where you were.
