After losing 4 cards (1 G miniSD, 4 G ultra SD and 2 x 2 G SD, all Sandisk), and not being able to recover any of the I was about to give up. In my previous post I asked if anyone with a Kingston card had had any problems, and no one responded, so I tried one: 2 Gig SD. Its a week later and no problems (which is an excellent improvement on the half day that I got out of the las 2 sandisks) I have not been treating it with kid gloves either - have loaded a few movies and a number of albums onto it via wlan as well as usb between the n800 and pc. So far so good. if anyone knows of a blown Kingston please report here. Request for the moderators: is it possible to have a poll so people can give stats on their experiences?
