Had some issues with big 32 gig card in my old Vogues, things like slow search and long gaps between songs even when player is in gapless mode. Have found only a couple of things that help:

(1) Format FAT32 with 16KB cluster size. This should result in the same RAM requirement as an 8 gig card with default FAT32 cluster size, as far as what the file allocation table needs.

(2) Using a ROM with at least 32MB pagepool size. That's about 30% of the 116MB of RAM available in my Vogues with custom ROM. Have tried pagepool size at 40MB, but other things get compromised, like opening large file folders takes forever. Your HD2 probably has alot more RAM, so you might do well with a 48MB pagepool size.
