I'm trying to install Plan9 on a computer (256MB ram, Intel Celeron 2.00Ghz,
160GB hard disk). At the installation proccess, I go up to part disk. Then
it shows me that it made the new Plan9 partition (2.45GB), so I type 'w' and
'q'. Then I get this:

 Preparing menu... read: i/o error

and it prompts me again to partdisk, and it never ends. I really don't think
that this is the hard disks problem, it's a barely used 160GB Maxtor drive.
Has anyone had any problems similar to this? Could it be because some of the
hardware? (Unlikely, but...)

Regards,
Yosyp

Sure about the disk? Disks may be broken when they arrive (broke on transport), etc.
'Not used much' may mean 'maybe I could not yet discover the issues'

So what is the controller involved? What chipset, etc?

I've been using this disk for data storage for approximately the last year
or so, but it's possible. The Linux partition on the disk has data on it,
and I'm able to read/write on it. (Last time I checked). Found some
information:

Intel Corporation 82845G/GL/GV/GE/PE DRAM Controller / Host - Hub I/F Bridge
Display is VGA 82845G/GL/GV/GE/PE Integrated Graphics Device

Then there're the 4 or 5 USB controllers, Hub interface to PCI Bridge, LPC
Interface Bridge etc. I will try installation with another disk in a couple
of hours.

try booting linux to see if you can write to the hd.  the output of lspci -vn
would be helpful if you find the disk to be good.

if this is an ich5 or ich6 motherboard with sata+pata (that would be all of 'em), 
you're going to have trouble with sata drives.  the port configuration is nonstandard
and the ide driver doesn't know about it.

if you do have such a system and you do have an ide-only system, there's probablly
a ide-only bios option that may let you boot.

this isn't quite the right info.  try lspci -vn from linux.

I'll try that, but I tried something different earlier. I put in an 80GB
disk, it has one ext3 partition on it (80GB). I resized the filesystem
(resize2fs), and I booted from a liveCD and trying parted, but it doesn't
want to go.

#parted
(parted) resize 1 0 60G
No Implementation: This ext2 filesystem has a rather strange layout! Parted
can't resize this (yet).

Then I  remove journaling to make it truly ext2;
tune2fs -O^has_journal /dev/hda1

#parted
(parted) resize 1 0 60G
No Implementation: This ext2 filesystem has a rather strange layout! Parted
can't resize this (yet).

Just if you're wondering, I resized the filesystem to:
/dev/hda1   Used:38436MB  Available:1699MB  Use:96%

>From the resize2fs() manpage:
If you wish to shrink an ext2 partition, first use *resize2fs* to shrink the
size of filesystem. Then you may use
*fdisk<http://www.die.net/doc/linux/man/man8/fdisk.8.html>
*(8) to shrink the size of the partition. When shrinking the size of the
partition, make sure you do not make it smaller than the new size of the
ext2 filesystem!

I've looked into fdisk(8), but found no way of shrinking a partition. I
might be able to delete it and start it at the same cylinder, but that
sounds risky.

That's exactly what the resize2fs man page is saying you should do.

I would stay far away from GNU parted.  I've had nothing but bad
experiences with it.

I shrunk the partition on this "new" disk (80GB), and left 27GB to
Plan9. Trying to install, go past configfs, to partdisk. I follow the
steps (it does the allocating automatically), then write it and quite.
No errors, but it puts me back to partdisk again, in a loop. This is a
different disk, and no errors are displayed, this gets me really
confused.
