Some comments seem to indicate that the problem is due to alignment, and
some due to ncq. If it is an alignment issue that should be fixed since
partitions are now alined to 1 MiB by default. If it is an ncq issue,
then it's not a bug in parted, but a hardware defect that may be worked
around wit

This looks like the drive is rejecting IO requests that are not 4kb

Can you post the output of the following 3 commands:

But due to man mkfs.ext3:
stripe-width=stripe-width
Configure the filesystem for a RAID array with
stripe-width filesystem blocks per stripe.

Hi Colin,
So sorry for the delay - been up to my neck in work and kind of forgot about
your request.

Did you get a chance to get the tarball of /sys/block/sda/ that I asked
for? I'll need that to make sure I get the code right, I think.

Thanks for that! That doesn't look *too* bad, so I'll see what I can do
to get something similar integrated.
Could you attach a tarball of /sys/block/sda/, just so that I can make

OK... problem solved (at least, sort of...)
the installation failure is entirely to do with the ext4 file system.
using ext3 gives no problems whatsoever. this is irrespective of whether
or not the ssd is correctly balanced.
the correct balancing for a 128k erase block ssd (most ssd but not ocz)
The size difference is actually a red herring, and nothing to do with
this bug. GParted shows sizes in binary units (note the "i" in "GiB"
after the number) - a GiB is 1024 * 1024 * 1024 bytes. The installer's
partitioner, partman, shows sizes in decimal units (GB) - a GB here is
1000 * 1000 * 1000
and this is the partition manager screen photo...

It does sort of look like an alignment issue (and the fact that LVM
makes it work is very suggestive of this), but I agree that it's
surprising that that would make it not work at all. I don't have a quick
answer for you, but since this is important for performance on other
SSDs anyway I hope that

Please do a test installation using the desktop (live) CD up to the
point where it falls over, and then *before rebooting* attach these two
files to this bug report:

it doesnt work, the installer cd still mis-represents the size of the
partitions.
crucial support (us) also suggested using GParted to form a unformatted
partition which could then be used. once again, doesnt work
the installation fails universally at one of 3 points:

What happens if you make your partitions yourself using fdisk/gparted
before doing the installation? Afaik the alignment of partitions affects
performance on SSDs but shouldn't make it not work at all.

Apprently the 256gb SDD drive does only have 238.47gb of usable space...
so, therefore, my unit is fine.
What I'm guessing is that the installer disks are trying to partition to
the declared 256.1gb and so are crashing when unable to
