I'm building a new system from scratch to predominantly run node-RED, and needed a independently-powered HDD in preference to either a SD card, or a HDD sharing the same power supply as my Pi for resilience.
Whilst looking what external HDD's were available, a friend commented that they had ended their Sky contract - anyone want the box before it goes in the bin?
That seemed too good an opportunity to miss, as I knew that they contained a Seagate 500GB SATA 3.5" drive ....so the project started this afternoon.
Removing the HDD was pretty easy, and only a small pozi screwdriver, and a sharp knife (to cut the cable ties) was needed.
I purchased a 3.5" SATA USB3 HDD caddy from Ebay for ÂŁ13, I chose this one because it's constructed from aluminium & vented so it should stay cool, although similar caddy's are available from AliExpress from ÂŁ5 delivered.
The HDD simply pushes onto the caddy interface, and then 2 screws hold the lot together - very securely
All done!
I formatted the drive, and then ran SeaTools on the drive for an assessment of it's condition, which came back OK, so next stage is to attach a Pi and install an image.
