[storage-discuss] Disk Size Limits For 32/64-bit Kernel

[Andrew]

To verify for myself before buying a 1TB drive I did the math.

The comparison in cmdk.c is:

if (#blocks - 1 > DK_MAX_BLOCKS) then fail

where 
DK_MAX_BLOCKS = 2^(32-1) = 0x7fffffff

#blocks = 2147483648 = 1024GB * 1024MB * 1024KB * 1024B / 512B (block size)
#blocks = 2147483648 = 0x80000000 = 0x7fffffff + 1

so a 1TB drive should work.
