I suddenly started getting a "microSD is not ready" error. I've ejected both the mSD and the Gateway cart itself, but it didn't make a difference. I've tested it on multiple devices, and checked that the mSD can be read by a PC (it reads fine). I've run Gateway's diagnostic tool multiple times with inconsistent results during consecutive tests, but it generally fails. I've also attempted a forced update to the Red Cart by holding R while booting, the installation and verification succeed, but it still fails the diagnostic test. Anybody encountered this before? If yes, any suggestions or solutions? I'm prepared to buy another if necessary, and I suspect it will be.
