I have a whole bunch of topics to address with my Lenovo PX4-400D NAS but I'll do it one topic at a time.

 

Is there a way to stop UNRAID from seeing the it's 1GB internal flash drive? I want to buy the Basic package but it's taking up one of my 6 valuable device slots. It's showing up as:

 

Name:

Dev 1

Identification:

_USB_DISK_2.0_65003C1BAA4A2A08-0:0 (sdb)

 

It's an unassigned device but it's getting just as many reads (millions) as the drives assigned to my array.

 

I suppose I can eventually figure a way to boot UNRAID from it, but it's really too small to do anything with. Currently I'm booting off a 64GB USB 3.0 flashdrive.

1GB should be enough to boot Unraid from.

@HDGuy, or you should be able to just remove it physically.  (Flash Drives are notorious for having high failure rates compared to most electronic devices...)

It's embedded memory.

I'm trying to boot from it following this guide but when I get to the point when I'm supposed to restore the boot block it won't let me do it (says files aren't there, they are). I think it has something to do with running a linux program off a Fat32 drive.

IF this is true, there may be a setting in the BIOS to turn it off.   (Still find it hard to believe that Flash memory would be soldered to the MB.  I have heard of a one other manufacturer who had a flash memory inside their product but it was a standard USB flash drive connected via a header on the circuit board.  The reason I know about it is that there were a lot of questions about replacing it when it failed.)

The LenovoEMC PX4-400D was originally a NAS running a modified BIOS, so there is no way to turn off the internal flash memory (at least none that I could find). I already had the motherboard out to upgrade the ram to 8GB and install a PCIE NVME controller (yes, it has a PCI-E slot), and while it might have a header somewhere for the internal flash somewhere on the motherboard, I wouldn't know where it was. The motherboard doesn't seem to be one that was commercially sold. 

 

If I could get it to boot Unraid off the internal flash it would solve a lot of problems for me. I have no idea how Azxiana did it without encountering the same error. I tried contacting her a few times but she hasn't responded.

If it isn't a "normal" flash device probably can't be used to license Unraid anyway.

If you look at that link I posted Azxiana appears to be running a licensed version off it.
