Clip Zip - Files that play on int 4G but not ext 32G card

[dksca]

 First, I want to say THX for all the effort from everyone for supporting & making this SW available.

I've been using CLIP ZIP 4G + 32G SDHC for 3 mo. , heavily - OK, D/L dev builds daily (last d66c167).  I make
files from my CD collection using the latest EAC, Lame, Flac, EncSpot & Mp3tag for many years - no problems. Today I've
come across some FLAC, WAV & mp3 (actually CD) that play on the int 4G but stop at 0:00 on the ext 32G
(doesn't crash the player). They play fine in Winamp thru the USB from 4G & 32G card & from PC.

01 The Band - Strawberry Wine.wav
03 The Band - Time to Kill.mp3
07 The Band - The W.S. Walcott Medicine Show.flac

Noticed I can't attach them total size 50Mb zip. Would like to make them available for testing purposes.
Any comments / help / reality check would be greatly appreciated 

PS - unrelated - USB crashes the Clip Zip in at least a half dozen situations but more on that another time...
       IMHO - the Sandisk SW is useless...long live open source

First, please use full words, not your own abbreviations. I very nearly replied saying Rockbox doesn't support ext file systems, until I realised you meant external.

If the tracks play fine on the internal storage, then it is unlikely that they are the issue themselves.  How are you copying them to the sd card?  Could you try copying them from within Rockbox (i.e. from the internal flash to the sd card)?  It might be worth doing a disk check on the sd card (either fsck.vfat or chkdsk depending on Linux/Windows), but it sounds like Rockbox might be having trouble with your sd card.

Sorry for the vagueness thanks for the help. I agree the suspect files are probably not the problem.  I copy files from my Windows XP SP3 server thru home network to my Windows 7 SP1 Home laptop where the Clip Zip is attached (Drive E: & F:) via (short) supplied USB cable. Chkdsk shows OK sd card thru the USB. If I remove the 32G card and plug it directly into the USB (tiny adapter) the suspect files play fine in Winamp, Chkdsk shows OK sd card.

I tried deleting them from sd card (thinking indexing) adding some new stuff and recopying the suspect files and now they play correctly!

I'm still checking if any other files have problems. I may have intermittent sd card or Rockbox problem? Will keep looking...THX
