I deal with computer problems often, but this was a new one!
My Sandisk Ultra+ 256 (SDSSDHP256G) was purchased about a week ago, and comes bundled with the latest X2306RL firmware. I put it in a Thinkpad X200, and when it boots the BIOS shows a “Device Error” until I manage to soft-reboot the system. On the second POST, the drive is detected properly and boots fine. This behavior is consistently reproducable on every boot from power-off.
The X200 has this problem on both its original 2011 firmware and the latest 2013 firmware update. Apparently these run the Intel Montevina platform, so I’m curious if anyone else with a similar chipset has this problem.
