I just got a m230 512Mb from my wife as a little gift, and after putting a few songs on it and tested it out, It worked great, good sound and FM from a little device. I then wanted to put a good mix of songs on it for working out and to fill up it’s space. after placing all of the songs on it I wanted I unpluged it from the computer, and let it update it’s library as I slept. When I get up I go to it and turn it on to see it will not get past the initializing screen. There are no fermware numbers just the Sandisk logo and initializing below. I plug it into my computer but it is not seen in mycomputer or if I go through any other programs or means. I have tried the fermware updater and it does not see or respond to it eather. I am wondering if there is a manual reset to the device or if there is a software “backdoor”. I like the little thing but I only heard it play music once and now it’s froze up.
