Well, I see good intentions, actually. Recovering data is possible after one uses the delete function. When we delete a file, the memory area used previously by this file is made available. Formatting a data area is quite different, as a null character is written to the entire data area.
Using a magnetic drive, there are methods of recovering the “ghost” data that has been overwritten. This is why we use special formatting software for secure data, which rewrites the area several times. Recovering the data following a flash memory format is not possible using this method.
I don’t have any “red” data on my Sansa, so no worries.
Using the guides I provided above, you can rewrite the reserved partition and recover your v1 (PortalPlayer processor) e200. It just takes a wee bit of time and concentration, especially if working in Linux isn’t familiar territory.
