750GB limit? Why?

[larry moe 'n curly]

Why do some older hard drive controller BIOSes have problems with
drives larger than about 750GB or 1TB? IOW why are there limits at
750GB and 1TB, as there are at 8.4GB and 137GB?

Some affected controllers use the VIA 6420, 6421, and 8237x SATA chips
or Silicon Image 680 PATA chip. Silicon Image released a BIOS update
to take care of a 1TB limit on RAIDs.

There should not be a limit in that range. The next one
is 32 bit (SCSI) sector numbers with 512 byte sectors,
i.e. 2TiB. I am not disputing your statement, I just do not
see a good explanation. Maybe planned obsolence?

There is anyway.

Mindless conspiracy theory. Its MUCH more likely that someone ****ed up.
