Hi,
I have developed an eVB application for a client who needs to keep critical data on his PDA (model is QTEK 2020).
To prevent memory loss on hard reset, I keep everything on the internal "Memory Card" (the 14.5 Mo on the ROM, no SD card), in a subdirectory under the \storage\ directory. This is supposed to be nonvolatile memory.
The problem is that one user ran out of battery, and when the PDA was reset, the application and data had totally disappeared from the storage folder.
So here are my questions: is it possible that, under certain circumstances, the internal storage space can loose data? Has this ever been reported? Would an SD card be a more reliable solution?
I first suspected the user had done something wrong (such as unwanted deletion of folder), but this seems quite unlikely as she performed very basic operations.
