Hello

When my F2-425 had TOS 6 I could see for example serial number, disk temperature and firmware on my external Seagate disk connected with USB but in TOS 7 it is not working. S.M.A.R.T is obviously not working anymore and in TOS 6 Ironwolf Health Management was working but not in TOS 7.
Does anyone know why? Is it possible to fix in a new firmware?

It seems to be working on my f5-221 (only nas I have with Ironwolf installed).
Smart-info also seems to be working.

I have a D4-320 with 4 x12tb Iron Wolf Pro which is attached to my F4-424 Pro and (smarts) is working.
Also for temps, I see them on the device monitoring overview screen



actually everything you are looking for, I see it this way

You can refer to the location shown in rfbjr's screenshot to check if the external hard drive information is visible. If you cannot see it, please provide screenshots of your page; alternatively, you can use the `smartctl` command in the terminal to check the drives for any anomalies.
Replace X with the actual hard drive letter.

Just to clarify or note, the drives in my D4-320 are mounted/attached to the F4-424 Pro as a storage pool.
