Internal memory unknown format

I have the same problem as Tanglust.. Do u have the solution for this problem? Thank u. Problem:posted by Tanglust on Jun 30, 2006Report abuse Got this message "internal memory unknown format". Went to Rio's site, 1st suggestion is reformat drive -- not able to because drive is not recognized. 2nd option do a flash. The flash software does not see the rio. I double checked all the drivers, they are all working fine. But description of drive is unknown. I just upgraded to windows xp professional. And it shows as two different storage files. I am soooooooooo confused can you think of anything else I can do ?

It can't play songs that are save to it, i have songs saved on my x20 but when i take it off from the charger it says that there are no songs saved

With your player off, and not connected to computer via usb, hold in the menu button.

2. Still holding the menu button, press the power button. Continue to hold both the menu and the power button until you see the option to format internal memory.

3. Format the internal memory.

Your player now works again icon_smile.gif

File system errors / possible firmware bugs.

Here are some observations.

With the internal memory formatted by the player itself:

1) The player always has multiple malformed root directery entries that don't show up as files in Windows Explorer. Particually, the "Services" folder is slightly malformed. On some systems, the Services folder won't show up in Windows Explorer (like Windows 98).

2) Any memory formatted by the player whether intneral or a microsd card, will be completely missing a partition table.

If the internal memory is formatted by anything else other than the player itself:

1) The player will not be able to write the library database and user settings to the internal memory. The song and artist names will always be "Unknown" and "rebuilding library" every time the player is truned on. The library database and user settings files show up as multiple zero length files in the root directory, one with the same name for each time the player is turned on.

2) The Audible directory will be created and filled with many, many garbage files with garbage names with very big sizes that don't actually take up memory space.

3) Trying to use a microsd card that was formatted by anyhing else results in the player hanging when rebuilding library when it tries to scan the external microsd card. The player has to be shut off buy holding the power switch.

Flash error please format the player

Have you tried formatting the player. It sounds like the internal memory is corrupt. If the unit is under warranty have it serviced. Otherwise replacement is your next best option.
Thank you,

Press the MENU and turn it on, as soon as the word RIO shows on the screen release the power button but do not release the MENU button until it says upgrading
Plug the USB cord to it and install Rio Forge Firmware_120
Turn the mp3 off then on normally
Put the music back on your mp3 and it SHOULD be fixed. but your music will be gone..

hope this helps,

You need to connect the Rio to a PC and then use the Windows Explorer format disk feature to reformat the Forge's flash memory as a FAT32 partition.
