GoFlex Home - IDE Reset powers off device (7 replies)

Appears to be a great community and knowledge base on this forum which has helped a lot over the last few weeks.
Any help would be greatly appreciated.

The Issue
As the GoFlex Home boots I get an intermittent green LED for a number of seconds, I hear the SATA disk begin to spin up, then the entire GoFlex device powers off.

Brand new disk, up-to-date uboot and new-ish kernel & rootfs.
See below for more details.

Background
My trusty GoFlex Home has been running great for a number of years with Arch, but I now wanted to fit a SATA disk with more storage space.

The uboot was very out of date and I wanted to switch to debian.
I therefore fitted the brand new SATA disk and updated to the following listed below with the respective guide links.

UBoot 2017.07 - https://forum.doozan.com/read.php?3,12381
Debian 5.2.9 Kirkwood (25/08/2019 as per first time install note) - https://forum.doozan.com/read.php?2,12096

I was able to boot fully (through uboot and the kernel) and use the distro fine from SSH prior to the issue existing.
However ,every boot now powers down the GoFlex (appears to be at the point "ide reset" is issued); NC output below.

Just in case it helps, on the last successful boot, I issued:
apt-get update
apt-get upgrade
reboot (and then powered off for a number of days)

Note: As indicated in the Debian rootfs guide, if apt-get updates initramfs, uInitrd should be re-generated. Which I did as specified before powering down.

Other notes
-I have also used CloneZilla to create an iso from the new disk prior to the issue presenting.
-Exactly the same occurs when the 3.5" SATA disk is fitted within a powered USB SATA caddy and connected to the GoFlex by USB (to rule out power draw of the new disk).
-A USB flash drive boots successfully within the GoFlex and I can SSH in (without the SATA disk connected).

NC output when issue occurs
Note nothing else is listed as the device is then "offline".
