Cowon D2

Ah, it all becomes clear! Those are all single-bit errors, which is almost certainly because the NAND driver does not yet implemented any error correction (ECC). Nothing to do with the FTL, phew!
It should be relatively straighforward to add ECC, but try as I might I couldn't get any errors to show up on my D2 at all, so it makes testing rather difficult! It's another one for the to-do list I'm afraid...

I've got a 8GB D2+, maybe that matters.
UP: Then again, since grantmasterflash gets the same kind of errors on his 16GB D2, probably it doesn't :-X

In my experience, I find one of these error-inducing files approx. every 10-12 tracks - for example, one track per flac album on D2 exhibits this problem. If you rip a few CDs to flac (or convert 20-30 audio files you have, whatever you prefer), transfer these to your D2, load them into a playlist, and start listening, I would bet you'll encounter this issue (or at least I hope so, for the sake of getting to the bottom of the problem).

So how about a "how to reproduce" ???
If a bug is easy reproducible by someone that knows how to fix it, i'm pretty sure that it will be fixed. So if you really want to fix this thing ..why don't you give a hand ??
- steps required:
1) find Rockbox versions used
2) pick n tracks, [free tracks if possible :) ]
3) clear the player [delete all files except Rockbox - maybe a clean install would help more ]
4) copy files to the player [describe how...if you think it might help]
3) listen to the skip, mark it down somewhere
4) repeat procedure - see if reproducible
5) zip everything
6) if possible ask others to reproduce [with the zip]
6) file a bug (you know ..we have buttons in the left up :) )
7) then ask what can be done in order to help more the debug
Since you said is easy ... it shouldn't take you too long, besides...do you know how frustrating is to try to fix something that you can't reproduce ?? and it might take a lot of time, to find the bug...time that could be invested in other ....bugs.
