I run Dban to wipe the hard drives when I am selling them, or whatever software is recommended by the SSD manufacturer or the motherboard utility. If I am selling an old PC, including a drive increases value and makes it more attractive. I only ever include OEM software if I had such installed.
And if anyone can get data of a drive even after using Dbans quickest wipe I will buy them a bag of donuts.
There is no real reason to be paranoid, nor is there any reason to hoard old drives, or in the case of an inept IT manager smack scuzzy drives with a hammer.
Plenty of software is available to wipe a hard drive, and the majority of people are not going to waste time and resources trying to uncover someones secret jam recipes or undisclosed Nicola Sturgeon fetish or indeed bank detail from a drive sold as blank. Dban is really easy to do, has various settings, and believe it or not, there is not a secret group out there targeting second hand hard drives as possible data theft. If there was second hand drives would fetch more than new on eBay.
But do wipe it with something like Dban for HDD (not SSD) or the SSD manufactures erase software or something like ATA Secure Erase. Google those options before hand to get an idea on what does what.
Of course, NEVER sell an unwiped drive. I have bought second hand PC's in the past, and one comes to mind, it was an ebay purchase, turned out it was a family PC and just about everything was available on the drive, including family members facebook, ebay and bebo passwords and account details, browser history, thumbnails of search history and posted selfies etc. Without using any data recovery software! The owner had simply deleted the folders they thought relevant while trying to leave it as a complete PC with it's original Windows XP install.
I let the seller know this and wiped the data myself. One because I am honest and two because I do not trust the security of someone elses second hand operating system. I would run Dban on second hand drive purchases too before use.
