Unable to change powermode seagate expansion +

[atokje]

Hi.
I have an issue with my new 2.5"HDD, where it doesn't automatically spin down or go in to sleep mode. I have tried installing openSeaChest with the latest git pull. unfortunately I'm unable to change the power settings on it, and get this error message:

/dev/sg0 - Expansion+ - NA***** - SCSI
Failed to check if drive supports modifying power conditions!
ERROR: Could not change power mode settings.

It also seems to me that I don't get all the info from the HDD:

Is this a bug within the openSeaChest, or is it just the lack of support from the HDD firmware?

Hi @atokje,

If I understand this correctly, pass-through support on Seagate USB products with UAS support is blocked by the Linux kernel, so it is not possible to issue the necessary commands to the drive to change these settings.
You may be able to do this in another OS, like Windows though (although I know that is not a good solution either).
If you look at this link from the smartmontools documentation, they have a lot of detail about the issue and how to work around it, which may make this work for you.
