This barrier was overcome with Int 13H extensions, which used 64 bit linear address and therefore allowed access to the full 128 GB and more (although some BIOSes initially had problems handling more than 31.5 GiB due to a bug in implementation). ATA-6 introduced 48 bit addressing, increasing the limit to 128 PB (or 144 petabytes). ................
