The only drive size limit is the 128GB per-drive limit of the original-style IDE drive register set.

The 2.2 kernel series used in the player does not support the new extensions for addressing drives larger than that size (although I could hack them into the player's kernel someday).

I don't know what the "max files" limit is -- that depends entirely on how the player builder software issued the "mke2fs" command to create the filesystem.. but that too is hackable.
