Spreadsheet - Strange Content

[cyrille de brébisson]

Hello,

This strange "content" is how a "bad" real will display (your mileage will vary depending on your value of "bad").

This means that the memory was corrupted, somehow.

Since I am perfection incarnated, it could not have been my programming, so the memory corruption has to have been caused by some "act of God" (insurance definition thereof). Have you been in a place with a high level of cosmic radiation lately?


So, what can you do?
Well, corrupted memory, usually means that the device is likely to crash at one point in the session where the memory was corrupted.
Interestingly enough once corrupted memory gets saved to file and reloaded, the data stays corrupted, but the memory structure itself is NOT corrupted anymore!

So, let us look at the possible cases:
1) Memory is good, Some data is in spreadsheet in RAM, Some data is in spreadsheet in Flash.
- Reboot means loosing data in RAM (Flash data remains)
2) Memory is corrupted, Spreadsheet data in RAM is corrupted. Calculator will crash at one point.
- If you can SAVE the corrupted RAM data in Flash, AND if a subsequent reload does not Crash, you will end up with a NON corrupted memory, BUT Spreadsheeet content containing BOTH corrupted AND uncorrupted data...
3) Calculator crashed, spreadsheet DID reload (ouf!)
- You have ALL your DATA + corrupted stuff

1) is the normal state.
2) is bad as you will loose data in case of reboot/crash.
3) is "good" as your data is NOT lost. All you need to do is erase the crud.

So, obviously, what you want to do is go from step 2 to step 3 so that you can cleanup the "mess".

To do that, turn the calc OFF (which saved all the files to Flash), turn it back on and reboot (ON+Symb). This places you in step 3 (if all goes well), at which point you can recup your data if all goes well.

I am sorry to hear that this is happening to you. If you can find a reliable way to reproduce it, please do tell me!
