Hi,
I recently bought a SSD disk to pimp ye ol X40 notebook. The device is a
"Mach Xtreme Technology Nano 44Pin Series 1,8 Zoll PATA SSD - 60G" (see
dmesg below). Currently, it looks as if my expectations towards gain in
snappiness, power consumption and quietness are met.
After roaming a number of lists however, I learned that SSD disks are best
aligned along 128k boundaries due to the erase block size. That's what I
intended to do when installing the system again yesterday (current
snapshot):
As the BIOS of the X40 does not support setting (and showing) drive
parameters, I have no idea what the BIOS thinks is the disk geometry. The
only way to guess that is looking at the fdisk C/H/S values, however this
might potentially also be set by the disk driver.
fdisk reports the geometry as 7732 cylinders / 240 heads / 63 sectors,
which is ok, since it at least divisable by 8 and aligned to 4k.
I want to change that to 9320 cylinders with 224 heads (32*7) and 56
sectors (8*7) in fdisk interactive mode (disk). However, I cannot set the
right cylinder size, since fdisk says that the "BIOS Cylinders" must be
between 1-1024.
The reason is that src/sbin/fdisk/cmd.c has "BIOS Cylinders" hardcoded
(maxcyl = 1024, roughly 8G then). Is there any necessity for limiting this
value? If not, could we raise it to something more contemporary, like 2^16
or more (I'd prepare a diff if I had a suitable machine at hand right
now)?
If I would save the MBR in interactive mode, the values given with the
disk command would actually persist and I'd be done. I mention this,
because the C/H/S values do not persist, if I issue an "fdisk -c 9320 -h
224 -s 56 wd0". The next call of fdisk gives me again the old geometry
(even when I use -u before).
I'd be happy if anyone could give me a hint on how to arrive at a point
where I can set the disk geometry persistently (and correct).
Thanks in advance,
/Markus
