Above are fdisk stats.
Can anyone tell me how to fix sda1 so it ends on a cyl boundry? I know I need to resize it (yes I know risks) but I don't know what to resize it TO!
Thanks

leave it as is. This status was caused from a early fdisk-program. Manny but not all Fdisk-Programms can handle lba48 the correct way. or some of the bioses can't handle lba48, or some ide-usb-converters will fail on this kind of request. |

I need to fix it because I can't mount the partition... and I think this is the reason why.

I don't know how and which tool you have used for partitioning. so there is only speculation howto handle this problem with normal tools.
Best is boot with windows and backup all NTFS-Data. since linux cannot do this for you. Hidden StreamData at the end of the NTFS-Part.
Having done this. boot linux and use dd if=/dev/zero of=/dev/sda bs=1 count=numer of sektors. This will clear the whole sda.
Reboot linux again since there a no partitions on sda available. and now use the cfdisk or fdisk to create the partitons.
keep in mind to format first the newly createtd linux-partition.
Next Reboot with windows and format the created ntfs-partition. Restore the windows data. Thats it. |

To clear all partitions:
dd if=/dev/zero of=/dev/sda count=1
(default is bs=512). When you use bs=1 you have got 1 byte, not 1 sector as blocksize. |

And if Kano's solution don't work, IMHO, I would start from scratch. I think schnorrer hit it well by saying I don't know how and which tool you have used for partitioning. That said, What did you use ?. Plan out the sizes of your partitions and the "type" of filesystems you will be using ie. NTFS, Fat32, ReiserFS, Ext3, etc....Of course make sure everything is backed up that you need/want. Yes this is a pain in the arse, but once done "correctly" you can continue computing and not have to worry about resizing later. Use common sense and make your partitions bigger (alot) than what you think you need, so this won't be a problem in the future. |

Al,
the given link doesn't work. So I can make only general comments.
As far as I know the problem as you state it is not the real one: some partition on sda, not necessarily sda2, doesn't start on a cylinder boundary.
Under these circumstances resizing is too dangereous.
What I would do: make (possibly compressed) images of all partitions of sda on a separate disk, then delete all partitions on sda and play all partition-images back onto sda in turn, starting on correct cylinder boundaries.
Some image software:
Paragon (english demo-version):
