Character Corruption For Example - ogg to oŧg & .ogg to Įogg

Hi All

I updated my late 2007 nonstandard version of Rockbox to an official version after I found that it now supported Album Art & a Last.FM Scrobbler log

I did a clean install on a freshly formated Fat32ext 30Gb HDD & renewed the Bootloader on my IAudio X5L

Since then I have had what I first thought to be a HDD problem, but the nature of the corruption looks more like a UTF-8 / Unicode mix-up.

I have since updated the builds mainly to keep up with the Scrobbler problem like *Panic* Unexpected Event on shutdown, which I got rather regularly. But the random character corruption continues.

It happens most often after I have written a file or folder to or read from my IAudio X5L using the PC.

But is also shows up even if I don't involve the PC.

Out of nearly 5000 files it only strikes 2 or 3 at a time. But if they are Rockbox files, then I can get a boot failure. Until I install a fresh build after which I can delete the old file.

Sometimes the corrupted character shows up as a dotted rectangle.

Apart from if the corruption hits the file extention. The only problem is finding what the new name of the file is.

I also use the Blackglass WPS that uses nedore-9.fnt.
The other fonts installed are helvR10.fnt & nimbus-12.fnt

Other details:-
This is my longest address:-

R:\Classical\Felix Mendelssohn Bartholdy\Calm Sea & Prosperous Voyage Overture Op.27\Oliver Dohnányi - Slovak Philharmonic\01 - Meeresstille und gluckliche Fahrt Overture.ogg

This is the most extreme of the names:-

R:\Anime\Mahou Sensei Negima\Dai Mahora Matsuri Live CD 02\10 ハッピー☆マテリアル（メルディアナ合唱団バージョン）.mp3

Examples of change :- Rockbox.iaudio to Ųockbox.iaudio or Œockbox.iaudio

Also I am getting an occasional glitch in freshly installed music files. This I fix by deleting then reinstalling the affected file or folder.

The glitch is not regular & not a dropout. Like you get with a buffer or CPU Bandwidth problem. More like a random error spike. Not surprisingly I am wondering could this be related to the above?

nls:
The fact that the filename corruption only happens to a few files combined with the glitches you get in audio files strongly suggests a problem with the disk in the player. Or possibly something corrupting data while transferring.

Denzyl:
Hi Nls

The only disc check programme i had that would recognise the X5L HDD was XP's own but it found no errors

I also tried a XP search for all files on the X5L to see if it was transfer related & ended up with 143 corrupted entries.

The thing is the corruption fell into groups:


* In 37 files ogg became oŧg
* In 28 files 07 became Ä°7 + none of the other track numbers were affected
* In 14 files .ogg became Įogg
* In 13 files R became Å’
* In 9 files r became Ų
* While in 9 files L became Ō
All the other types of corruptions occurred at least twice. The files themselves are still playable, before & after name correction.

So I will check for the obvious dirty connections and check all the cabling as well.

Thanks for the help.

Run a full surface scan using XP (Select the 'Scan for and attempt recovery of bad sectors' option).

Also try connecting to a USB port which is directly on the motherboard of the computer (usually one at the rear, rather than at the front).

Hi Yapper.

Well my PC is a bit ancient. It's an AMD64 3500+, so I only have the 4 USB ports at the back. Currently I have my Zip 250, X5L Cradle & Printer plugged in. But only power to the Zip & X5L are active, I aways only run one item at a time. Bad memories of USB ports & Win95  ;D

I also checked & cleaned all the connections on the cable, cradle & X5L

As you suggested I ticked & ran the 'Scan for bad Sectors & attempt to fix them' on the XP disk checker. After a short while it came up with the Finished Scan Button 'OK'.

I have manually checked the files rather than do the search after running the Disk Checker.

I found 10 versions of this file ųolitaire.rock in the games section interestingly they all reported creation times related to 10 earlier installations before the date & time of the Current Build of Rockbox installed. I deleted 1 of them and they all disappeared???

That was it.

The X5L is now playing a random selection of music to check files while I write this. No glitches so far :)
