I have a primary (boot) SSD and a secondary HDD (via a SATA-to-USB adapter) connected to my computer. My goal is to sell the secondary HDD without exposing any previous data that was stored on it. I just performed a format D: /P:0
via an admin cmd.exe instance on the drive. Afterwards, I noticed that Windows created an invisible System Volume Information
folder on the drive. I then scanned the drive for recoverable files (with Recuva) and only found 24 system files. However, afterwards I noticed another invisible folder created at the root: Recycle Bin
. After clicking on it, and then another Recycle Bin
subfolder, I found a large number of personal files. I subsequently 'emptied' all these files, without trying to discern the origin (SSD or HDD). My guess is that this folder simply links all system recycle bins into one 'view,' as I performed a subfolder-scan with Recuva aferwards, and it only displayed desktop.ini
(while 'emptied' files from the Recycle Bin are presumably recoverable).
Are some files that show up in the Windows Recycle Bin of a fully formatted secondary drive linked or physically present?
1Where are files in the Recycle Bin stored, in respect of partitions? – Almost a duplicate: XP there, Win10 here. – Kamil Maciorowski – 2018-04-25T17:05:56.890
Note you wouldn't experience this issue related to Recycle Bin if you used a better tool. As far as I know

creates a filesystem. This was not your goal. Filling with zeros is just an extra (optional) effect offormat
. I'm into Linux, so I'll give you mostly Linux examples of better tools:shred
,dd if=/dev/zero
, ATA Secure Erase. My point is: erasing the drive without creating any filesystem would prevent Windows from creating any structures.Why are you using
format D: /P:0
instead offormat D: /P:1
