Could not format Kingston SSD SV200S37A/128G after firmware upgrade

Hey there, gorlum.

This sounds pretty odd. I gather you have no important data on it if you're trying to format it. First of all, if I were you, I'd run an SSD diagnostics tool to see if there are any issues with the drive. You could also try it with a different computer or at least with a different SATA port and cables on yours, to see if the same thing happens again. If you still have issues with the drive, I'd suggest that you contact the SSD manufacturer's customer support and ask for assistance.
You could also try secure erasing the SSD. Here's a tutorial on how to do that if you decide to try out this option: http://www.makeuseof.com/tag/securely-erase-ssd-without-destroying/ (note that I'd recommend that you contact customer support before trying this out).

Hope that helps.
