Yeah, that's the very first memory card that's ever failed me, and I have a drawer full of SD, MS, MS Duo, MS Pro Duo, CF, CF2 cards. I don't even recall having any HDDs fail on me either.

I find it strange that a memory card can just fail for no apparent reason. It's not like I've ever taken it out of the N810 before. Once it's in there, it stays in there for good.

I'll wait a day for Patriot to get back to me on the RMA (5 year product warranty), and then I'll try newegg for the RMA. It's only $30, so cost isn't an issue. It's all the lost GPS tracking data (that I wanted to use with geotagging), lots of xournal good sketches that my daughter did, my maemopad+ lists for everything important to organize my life, some voice recordings for meetings that were recorded, etc.

I think I've decided to write a pull-script to backup the N810 from my Linux server at home. I'll post those cron scripts here when they get done.
