Rockbox

When recording to the microSD card on an e200v2 the message "The disk is full. Press PREV to Continue." is splashed when the recording is stopped. The recording may or may not exist when you look on the microSD card. If the recording does exist, it has been truncated. The microSD card had approximately 100mb available.

Recording on the internal storage works fine. When recording in mp3 mode, the file was 1k larger than shown on the recording screen.

Rockbox build = r23746

Steps to reproduce:
1. Create a directory for the recordings on the microSD card.
2. In the file browser, highlight this directory and bring up the context menu.
3. Select "Set As Recording Directory"
4. Next, I went to Settings -> Recording Settings -> Format and chose "MPEG Layer 3" but the default PCM Wave also caused the same failure.
5. I started FM Radio and through the context menu started recording (MIC recording also fails)
6. On the recording screen, press the play button to actually start recording.
7. After some time, press the play button to pause recording. Make note of the size.
8. Press the power button to save the recording.
9. The disk full splash appears.
10. Press PREV to clear the splash.
11. Exit the context menu and the FM Radio.
12. Browse to your recording directory. If the file exists, check the properties. It will be smaller than the size noted on the recording screen.

Here are some of the recording size to file size comparisons I noted:
80.4 -> 79k
106k -> 95k
508k -> 493k
243k -> 238k
