As hard as MK and I worked on it after an upgrade it was dead. I was told there were imaged SSDs but not available at the time so I upgraded to an eISY. 

Now I want to replace an iSY994 for a low demand application. Can I resurrect the Polisy Pro?

Are the plug and play SSDs available again?

Can I re-image the current one?

@DreamerI90 that's a question best asked directly with UDI. I would open a support ticket to see if there's a way to repair the drive now or in the (near) future. There have been some recent issues with the 5.9.1 release that people were able to re-image existing drives of the Polisy, but it requires support help so best to just go that route now. Good luck!

Thank you Geddy!

DreamerI90, I suspect the hardware is still good and the data on the internal mSATA is somehow corrupted. If my suspicion is true, you may be able to resurrect your Polisy Pro hardware and use it for other purposes as I did. If that's of interest, please see the link that follows.
