Through trial and error - I think I have it sussed out now, not a solution but a reason why.
there was no indexing, no scheduled scans, no write caching enabled, it was optimised for quick removal and I still couldn't safely remove it, however my antivirus was running, so I turned it off temporarily and tried to safely remove hardware and Hey Presto! it worked. Turned the AV back on again and wouldn't work again. Tried turning AV on and off a few times and the AV is the culprit.
If I want to power down completely now I'll turn the AV off, not an ideal solution. X Activa.
