We have an embedded system running Windows Embedded Standard 7 (SP1 beta) on an SSD hard drive. We log data periodically on a SD card.
We had a power loss while the software was running (therefore the SD card was being written) and it corrupted the file system.
When I tried to format the SD card, I was able to sucessfully format it but the old file system kept coming back.
I had to finally format it using SD Formatter 3.0 (http://www.sdcard.org/consumers/formatter_3/) to get it back in shape.
Can anyone explain what happenned ? Why did the file system get corrupted ?
