Disk Utility Input/Output Error

[Daron]

Zephyroth's Leopard 10.5.1 DVD is the only one that seems to load up the installation process for me. so I'm trying to stick with this and get it to work...

Whenever i try to partition/erase my disk or any partition, it tells me that there is an Input/Output error. i've tried verifiying and repairing disk through the disk utility. nothing seems to work.

I have 2 partitions. the first is an NTFS with vista on it. the second is a blank partition.

Things I've Tried...
setting the second partition to "af" through Acronis
formatting the partition to Fat 32, Fat 16, and even No Format at all
setting the partition to Active
switching the SATA cables between 1st & 2nd port (this is both the HD and the DVD)
*and a combination of the things listed above.

I do not own a MAC or know anyone that does so i dont have access to any Tiger Installation disc, which i've been told might work.
there are no IDE ports on my mother board. i do not own any USB drives.

I've also read that i might have to set HD or DVD to master and slave or vice versa. there are no visible jumpers to make that selection and as they are SATA they connect to their own ports not on one ribbon like an IDE might be connected to make the selection.

what i find wierd is that DiskUtility can read info about the disk and even the NTFS. including the info about of space used, the amount of space left and even the number of files on the partition (the NTFS partition that is).

it will not mount the second partition either, unless its formated as NTFS. but even there i still cannot modify the disk or either partition due to the Input/Output error.

Please help me in anyway possible to get this working.
