48-bit LBA support?

OK I read about this support, and it was something so the OS can access the drives full capacity, which is something like 137GB. How come my SeaGate baracuda (which is 40GB, ATA-100) has this support? Is it also a data transfer mode aswell?

Should I turn it on? Or could that lead to a problem?

Thanks to whoever answers

the 48 bit support is only valid for large capacity drives, it essentially makes the system recognise a drive that is more than 137GB.

as you say you only have 40GB i suggest you leave it, atleast until you require the LBA support if you buy a larger drive.

No that will be the BIOS that has the support for it.

My other drive doesn't show that it supports it though

full ata compatibility requires '80 wire' connectors - make sure you have master/slave/cableselect jumpers set right, as well

Yep, I got an 80 wire cable with my mobo, both drives are plugged into that and are set-up as master and slave.

Just weird why one shows 48-bit LBA supported, and the other doesn't?
