Check smart external usb drive??

Zitat von ryuks

Would be possible to shown that info in order to check general status of external drives??

Yes, it is possible. But it depends of the SATA2USB-bridge controller which is used in the external drive case. That means it not depends of OMV but the capabilities of the used hardware and firmware of the controller.

E.g. I use a Fantec DB-ALU3-6G (Model #1659) USB3.0 case for USB backup. This case uses a ASMEDIA ASM1153E bridge controller. This controller supports SMART via USB also (By the way: It does not do 4K sector translation with drives > 2TB. This was the main reason why I bought it).

Does this device supports UAS? It could be that OMV has a problem for this device. You could try to blacklist UAS for this device in OMV and then make another SMART trial.

See here: No SMART access to Seagate devices under Linux if UAS is used

Which hardware do you use for OMV (x64, ARM...)? For Raspberry PI4 one solution is explained here: Rasberry Pi4 + Seagate External USB3.0 = No spin-down, no S.M.A.R.T. (100% resolved)

On my OMV system under Debian the solution is a little bit different.

Most tools have trouble passing the SMART status of hard drives over USB. Your best bet for getting the health status from the drive over USB from a generic tool
