This has been covered a million times, but technically with paul's new patch you can have some ridiculous amount (2.2 Terabytes I think?)

If you wanted 2 HDDs you would need a switch - they don't both work at once, yet.

2 to the power of 48 bytes is the maximum

281,474,976,710,656 Bytes
27,487,789,757 K Bytes
26,843,544 M Bytes
26,214 G Bytes
25.6 T bytes

think thats right

so, bung whatever the hells the biggest you can buy and it'll work

The 'protocol' to the IDE drive is known as LBA48 - allowing up to 48 bits per sector number.  But, the MS kernel only uses 32 bits for a sector number - that's a limiting factor.  Before LBA48, the limit was 28 bits.

So, with the "LBA48" patch, I've only enabled up to "2 to the power of 32" bytes of storage (approximately 2 Terabytes).

Again, there's possibly/probably a limitation in FATX that makes 2TBytes an unreachable size, but it'll be a while before we have drives physically large enough for us to worry about that.

(Edit) Correction: when I refer to "2 to the power of 32" bytes, I meant to say "sectors" (not "bytes").  Multiply "sectors" by 512 bytes to get the # of bytes (works out to about 2 TBytes).
