Subject: IDE corruption w/ 48 Bit addressing
Date: Sun, 16 Mar 2003 19:29:20 +0100 [thread overview]
Message-ID: <3E74C280.3000608@elitedvb.net> (raw)
Hi,
i'm having a PPC-405 based board (IBM STB04500 if anyone cares), and i'm
using a Maxtor 6Y200L0, a 200GB harddisk drive.
Obviously this uses 48bit addressing, and i'm using linucppc 2.4.21-pre4
devel. The same bug occurs with 2.4.20 release.
Users report harddisk corruption, and a quick test showed, that data
written to 0x1800000000+x (LBA sector 0xC000000+x/512) is also written
to x. (direct O_LARGEFILE-access to /dev/discs0/disc).
This will of course corrupt the filesystem.
Now my questions:
- is this a bug in the IDE low-level interface driver?
- or maybe in the kernel?
- or maybe fixed in newer versions?
- why does the corruption start at this lba sector?
User reported that this occurs with different HDD models and brands,
too, but only with 48bit-drives. Everything else works perfectly.
