Just letting you know but this happens to my HP-1 from time to time. I know this thread is about the x36 models but it just wanted to throw that out theirThis is MY 2nd report!
So my 436HP batteries ran low, but not enough to power itself off. So I had spare batteries, swapped them out, now I get the Message SD Card access Error message.
Unfortunately I had not had time to put my spare card inside the scanner. So not 100% sure if the SD card is the problem or what is going on. I will swap this SD card into my 536HP first to see what happens!
Original SD card
Will update when I have more info.
