Removing HDD before selling


I’m thinking of selling my older GEN1 MyCloud.
Before this I removed the HDD and keep this one.

Offcourse the MyCloud has got an Platino motherboard on it, Im just curious if this still contains private data, or can I just sell it without my HDD and everything is fine?

I didnt do any reset or whatever before, because I couldnt got connected anymore to this mycloud.

For the single bay/single drive My Cloud, generally all the user data in addition to the firmware is stored on the My Cloud hard drive. One can perform a 40 second reset which should reset the My Cloud back to defaults. But to securely wipe/erase the hard drive would require one to either access the My Cloud Dashboard > Settings > Utilities page and perform a Full Factory Restore, or extract the hard drive and wipe the drive using third party drive erasure programs.

What DSW is alluding to is the fact that on the GEN1 mycloud; the OS resides on the HDD.

If you remove the HDD; and replace it; you have to go through an “un bricking” procedure to reinstall an OS on the HDD.
