Post subject:  Update for Seagate Mach 2 2x18 drive with SC02 firmware?

Got two rare dual actuator drives with even more unique SC02 firmware. Now searching for an updated firmware. The only relatable firmware for this model I can find is SN03 which is not compatible.

With some research I found that firmwares starting with SC may come from Lenovo, but I'm still not sure about it, and there is no mention of dual actuator drives from any lenovo docs.

Anyone has any clue about it? Thanks.

Why do you want to update the software?

Would you be able to upload photos of the PCB, component side?

Because SC02 firmware seems to make the actuators do a seek action every few seconds no matter if it's idle or busy. I have another of these drives with SN03 firmware, and it does not have this kind of behavior(or it's less often, making it less annoying).

does this thing show up as two luns on the bus?
it seems like there are 2 complete controllers for each actuator, just as if it was 2 hdds except for the spindle...

The sata version, on some NAS platforms it showed two luns, but on windows it's a single drive.

nice way of building selfdestruct raids... if one component fails, you are finished :)

More like a JBOD. It came like this not what I chose to build.

I thought Lenovo firmware versions were LVnn, not SCnn.

Here is an SC25 video drive that has no hint of Lenovo OEM branding:

Yeah I saw a lot of Lenovo drive firmwares starts with L.

Wondering which vendor's firmware starts with SC.
