Installing an mSATA disk in an empeg

2019-03-29 15:25:00 +0000 empeg

Background

The hard disk in my spare empeg player died at some point. It’s getting harder to find 2.5” PATA SSDs, so I opted for a Kingston mSATA disk (240G) and a JMicron-based mSATA to PATA adapter.

But that left me with a problem: I had no way to install the player software. Ordinarily, you’d download the .upgrade file and apply it over a serial port with empegUpgrade.

But I don’t have a suitable Windows PC any more. I have a Surface Go, running Windows 10. It only just runs emplode correctly. I think my odds of getting empegUpgrade to work on Windows 10, with a USB-serial adapter are slim-to-none.

So: how to get the player software installed?

I do have a Linux desktop PC, so I bought an mSATA-to-USB 3 adapter, and connected the disk using that.

Partitioning the disk

Connect disk to Linux PC. It appears as /dev/sdd.

Partition it:

roger@roger-pc:~ $ sudo fdisk /dev/sdd
