System : OpenBSD 4.8
Details : OpenBSD 4.8 (GENERIC.MP) #359: Mon Aug 16 09:16:26 MDT
2010
[email protected]:/usr/src/sys/arch/i386/compile/GENERIC.MP
Architecture: OpenBSD.i386
Machine : i386
>Description:
Raw copying disk blocks with /bin/dd of an original Macintosh 500GB HD
on a MacBook Pro 13" laptop gives an input/output error at the
LBA48_THRESHOLD (0xfffffff or 128GB).
This is not related to a hard disk failure, but (suspected) to the
way Macintosh EFI Bios and Apple HDD Firmware interacts with the wd(4)
hard disk driver.
This problem shows up only with the Hitachi HTS54505050B9SA02
hard disk furnished by Apple, and OpenBSD installed from scratch, or
with the 4.8 OpenBSD i386 install CD starting up single user at the
shell.
This Hitachi hard disk label reads: Apple HDD Firmware 2009 500GB
2.5inch AT 9.5mm P/N:0A78255 MLC:DA3350
This Hitachi hard disk was not wiped or zeroed before installing
OpenBSD.
When using a 1TB Western Digital Scorpio Blue WD10TPVT SATA disk
in place, the problem could not be reproduced on the MacBook Pro.
On a "normal" PC (ASUS Motherboard, no EFI or Apple firmware) and
a LBA48 wd(4) SATA disk, the problem could not be reproduced.
The fix below is also used on this "normal" productive server, without
regression.

>Fix:
Removing the optimizations of the wd.c code wich where inserted between
revisions 1.23 and 1.24,
revisions 1.31 and 1.32,
revisions 1.40 and 1.41
fixes the problem
