I am using Sandisk 8GB micro SDHC card on my MileStone. The card is detected , mounted. I can read data from the SD card. But cannot write to it. There is no error when I attempt to write to the Card.It appears as if its working fine.But after umount and re-mount , the data written is gone. Even if I format it , it will restore to the previous state. At last, i try to format it, but the operation system formatting utilities is not working , it says "Windows was unable to complete the format". Then i use the "SD Formatter 3.0 Beta" from "http://www.sdcard.org/consumers/formatter_3/" , and it says "The Memory Card is write-protected Please release the write protect switch", but i can't find any switch on my micro SDHC card and SD Card Reader. I see some useful information on that web site , it says "The SD/SDHC/SDXC Cards have a "Protected Area" on the card for the SD security function. The SD Formatter does not format the "Protected Area". Please use appropriate application software or SD host device which provides SD security function to format the "Protected Area" in the card." I think my card may be wholly protected and how can i format it .

Are you using a Micro SDHC adapter. Basically are you putting the Micro SDHC into a SDHC card, which in turn goes into the card reader. I ask this because the adapter can have a write protect switch on it, even if the Micro SDHC doesn't. Example of write protect - http://www.transcendusa.com/Products/ShowImg.asp?ModNo=195&vplay=yes If not your card has gone faulty. Save your data and return it to scandisk for a new one - http://webcache.googleusercontent.com/search?q=cache:ft-qKl6oGFAJ:communities.sandisk.com/sandisk/board/message%3Fboard.id%3Dmobile%26message.id%3D1005+micro+SDHC+write+protected&cd=1&hl=en&ct=clnk&gl=uk | |||
