Re: HP 50G says the SD card is write protected Message #2 Posted by Vieira, Luiz C. (Brazil) on 7 July 2010, 12:23 a.m., in response to message #1 by Daniel Perry
Hi;
what is the memory size of your SD card? I succeeded formating 1GB SD cards in a PC and fully use them in the HP50G, but I never succeeded formating SD cards bigger than 512MB in the calculator itself. Also, even after formating a 2GB SD card in a PC, the calculator never reads more than 1GB. I tried to format the 2GB in the HP50G and, after an error message (don´t recall which one), the calculator identified about 997MB and the card could not be red in a PC (the computer asked me if I wanted to format the media...).
I also recall reading something about format error due to discharged batteries, because the formating process demands some extra current.
Because you can format the cards in your computer I guess that there are no chances that the LOCK switch is in the wrong position, right?
In time: OS Rev. #2.15
Not much of a help, though...
Success!
