For the next few months, I'm going to be zeroing out a lot of disks. I managed to get hold of a Host Bus Adapter (i.e. a PCIe to SATA expansion card) to give me an extra SATA controller in my tiny mid-tower, but there's no longer space in the tower itself to mount a drive, and even if there was, the temporary nature of the wiping means that there wouldn't be any point in doing so.
Whenever wiping a drive, I mount it on my desk and connect the SATA cables from my open tower to it. This works fine except for one problem - it puts some strain on the right-angled SATA power cable connected to the drive:
My worry is that after so long of being in this position the cable will start to wear or otherwise get damaged, so I want to balance the drive out and make it sit straighter on the desk. I did some experimenting and realised putting a flash drive underneath the disk balances it out nicely, but this still isn't ideal because: a) it doesn't prevent the drive slipping on the desk's surface, b) it might damage the flash drive, and c) I need my flash drive.
Is there anywhere I can maybe get a piece of rubber that's about the same size as a Kingston DataTraveller 100 G3? Or is there a less low-tech solution for something like this - some sort of external case that allows for the drive to be more comfortably mounted? Open to any solutions that work at this point, low-tech or not.
N.B. Any significant hardware upgrades are currently out of the question for income reasons.
