Fixing Ubiquiti Dream Machine (UDM) SE Hard Drive Not Detected Errors

Wed, 11 Dec 2024 02:34:43 +0000

My UDM SE can fit various hard drives. Ubiquiti have decided to have a cool tray the hard drive snaps into & slides into the UDM, which also means you have to have a very good fit. As it turns out, the fit may not be good enough without shimming the drive out!

I used a Seagate Skyhawk 4TB Video 3.5 Inch SATA (ST4000VXZ16/ST4000VX016) drive, which is reported as being compatible. In sliding the drive in there was no spin-up sound. I then tried rebooting it & repositioning the drive several times, it wasn’t clear if the hot-swap should work or not. But there was never a spin-up sound or a LED flashing on. Very annoying, especially if you are rebooting your houses internet for a “5 min project”!
