SiI3112 Serial ATA Maxtor 6Y120M0 incorrect geometry detected
From: micah milano
Date: Sat Sep 25 2004 - 14:16:08 EST
I've got two Maxtor 6Y120M0 drives, same firmware, but they show up
with differing CHS when I attempt to partition them, however it seems
like other places on the system they are detected as having the same
properties. This is making setting up software raid-1 difficult.
Should I boot with a particular geometry specified on the kernel line
to make it correct?
Using fdisk -l on each disk you see that one reports 255 heads, 63
sectors/track, 14946 cylinders and the other reports 16 heads, 63
sectors/track, 238216 cylinders.
This is 2.6.7 (i'm here because the ipmi software from supermicro is
not working for 2.6.8 yet), and I am not able to follow this list, so
please CC me on any reply. I've tried to include all the useful
information, but if I neglected something, please let me know and I
will provide it right away.
Thanks for any insight, this is driving me a little batty,
micah
fdisk -l /dev/hde
Disk /dev/hde: 122.9 GB, 122942324736 bytes
255 heads, 63 sectors/track, 14946 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
fdisk -l /dev/hdg
Disk /dev/hdg: 122.9 GB, 122942324736 bytes
16 heads, 63 sectors/track, 238216 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes
parted says:
parted /dev/hde
Error: The partition table on /dev/hde is inconsistent. There are many reasons
why this might be the case. However, the most likely reason is that Linux
detected the BIOS geometry for /dev/hde incorrectly. GNU Parted suspects the
real geometry should be 14946/255/63 (not 238216/16/63). You should check with
your BIOS first, as this may not be correct. You can inform Linux by adding the
parameter hde=14946,255,63 to the command line. See the LILO or GRUB
Information: The operating system thinks the geometry on /dev/hde is
238216/16/63. Therefore, cylinder 1024 ends at 503.999M.
parted /dev/hdg (no error):
Using /dev/hdg
Information: The operating system thinks the geometry on /dev/hdg is
238216/16/63. Therefore, cylinder 1024 ends at 503.999M.

Additionally, if I try to partition /dev/hdg (which has no partition
table yet), using fdisk, it strangley doesn't ask me for much
information, such as how large it should be:
fdisk /dev/hdg
The number of cylinders for this disk is set to 238216.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
