Dear POSSI:


Anyone KNOW whether this Is still true?

>From (2007),
"
On-disk filesystem structures

Jan van Wijk 

Filesystem on-disk structures for
FAT, HPFS, NTFS, JFS, EXT2 and ReiserFS
"
which says (p.13), about the HPFS,
"
FS-size upto 2 terabyte (2048 GiB) by design

OS/2 implementation limit of 64 GiB
  due to shared cache design
 (5 bits of 32 for cache use)
"

So, IF I read this correctly,
 my biggest HPFS partition can be 64GB in size? !


Sincerely,

Thomas Clayton

BTW, it does NOT matter WHAT size JFS partitions CAN BE, I'm asking about HPFS ones!
