Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Ι see it is a 4TB Hitatchi hard drive, so it uses 4KiB sectors for sure.
Gparted Live defaults to the MiB alignment since some years. win visa and win 7 align partitions to MiB, too.
Do you use Ubuntu 10.04? It is highly possible that it doesn't support properly such hard drives. I think these "advanced format" drives are in the market since 2010, so this distro version isn't up to date. Furthermore, 4TB drives are even newer, 1 year or less.
Sorry there C-9; I didn't know what other info was necessary, without cluttering up the post...
Allocation unit size is 32K (NTFS). Does THAT make a difference?
I presumed that when physical divisions of disk space are in MULTIPLES of the default / smaller units, then NO application could have a problem when looking at the disk, regardless of Windows or Linux environment...
Is there any chance that with 10.04 booted, a mis-mount / mis-read could occur, that causes boundary failure, or data loss? Everything IS backed up out of the machine (yep - I do have 34 TB of drives, FULL TOO!!! )
10.04 is used to manipulate W7, which is 'modified', and occasionally needs encouragement :wink: .
Wow, diging up info on hitachi has got harder since they got bought by WD.
Eventually though I found some data- it appears to be another '4K reporting as 512b sector' drive. Annoying.
32K cluster size wont make any difference. Some basic backgorund on advanced format drives here, and in patricular this bit (and its worth checkign the link if only to see the graphics that go with this statement)-
With the emulation of 512B sectors, there’s the risk that a partition could be misaligned compared to the 4K physical sectors - where it would be unwittingly started in the middle of such a sector. As a result, the clusters of a file system on that partition would end up straddling 4K sectors, which would cause performance problems.
