I’m finding that when I after I sync a bunch of aac (m4a) files from my library onto the 16 GB Micro SDHC card in my Clip Zip, the device freezes up during its “refreshing” cycle. I can scan some of these files on fine, but when I try to do my whole batch at once, it freezes. I’ve been able to sync a similar-size batch (1500 tracks) of mp3 files without a problem, and I’ve tried this with two different versions of the Clip Zip firmware installed (01.01.12 and 01.01.18) to no avail. I’ve also tried syncing through the card reader and then inserting the card into the device, but that seems to make no difference.
My guess is that there is a corrupt aac file in my batch somewhere, but it would be nice if the device could identify the problem file or even just skip over it rather than freeze up. Does anyone have any suggestions on how to fix this? Does anyone know of a program that scans for irregularities in aac music files so that it might be able to spot the culprit?
