Memory loss 20896kb

[gr37]

Well, I open a new thread because there was a serious change since the last problem I encountered. Remember I couldn't get SPA to properly detect my Rio500 (combined memory=0Mb).
I had to reinstall my OS, so I figured I could give it another try with a totally clean install. And, delight, it worked!
Formating the internal memory and the extension card (128Mb) was a breeze BUT my first transfer to the internal memory failed. The system hanged so I tried the 'cancel' button of the transfer window. Nothing happened for 30 secs or so and then the transfer window disappeared, the Rio turned itself off and on.
Okay... At this point SPA could not communicate with the Rio. I closed it, ran audioport to check on the player: no folder and 20896kb used. I tried to format the internal memory but these 20Mb are still missing.
Now, I had read about these memory loss problems, but I thought it could only happen when the battery was close to empty! It was not my case: I was using a brand new non-rechargeable battery (I even had 3 bars on the on-screen display which is pretty rare). You can imagine I was really pissed. Especially after I tried afterwards to transfer to the external memory (no problem) and realized I had lost my log forever.
Then I thought, 'a 20Mb loss render my internal memory meaningless anyway, so let's try it again so that I have a log'. Bingo! It did it again!. This time however, the loss was only 32k.
No more words (and tears), here is the log:

Where do I go from here?

Reading about what has happened to you has really scared me. I'm sorry but I can't help you but I have a question for Spoon.

When Rios are getting written to, the tracks are all written and then the TOC is updated from what I take it, something along those lines. When memory is lost in an interrupted writing, the memory is lost because the TOC or whatever the Rio manages the ram with was not updated. Would it be at all possible to have Sveta write and register with the TOC one track at a time? Sort of like a slow safe mode so when you did have an accident, that you wouldn't lose too much ram.

I will have a go at recovering the 500s memory once I have it. Taken to email.

So it lost 20MB? Was the file you were transferring more than 20MB?

I don't think this memoy loss is the same that other people have. It is one of the things on my list 'to do' - that is create a safe write so only 32KB can be lost if things go wrong.
