Wanted to throw in my 2 bits here... I purchased a Sandisk 256M SD card last year, and it began failing miserably on me withing the first week. By the end of the week the card would not even reformat in my card reader. There were a large number of similar complaints around the same time period, all related to Sandisk 128M and 256M cards. The interesting thing was that I found someone who had the same card with the same exact date stamp, and his was working fine. So it appears that the cards were randomly failing. I exchanged my card for a Lexar, and have had no further problems.
Now a question... Has anyone taken current measurements from any of these cards? I\'m not familiar with the technology of serial memory, but I wonder if there is any additional drain from larger capacity cards? 1GB SD sounds incredible, and I have yet to use up my 256M card yet.
