[ATA] Increase lba48 max-sectors from 200 to 256.
So was it for LBA28 or for LBA48?
As for LBA28, it might be quite dangerous. Particularly, I know
that IBM drives used to mistreated 256 as 0 in the past (bumped into
that on a 8-year old drive which is still alive though).
That's a typo. The first description ("lba28") is correct.
Let me know if your IBM drive has problems with current
libata-dev.git#upstream...
It's not likely I'll be able to try it. But I'm absolutely sure that drive
aborted the read commands with the sector count of 0 (i.e. 256 actually). The
exact model was IBM DHEA-34331.
255 sectors actually seems more safe bet.
