Your photo says sector 1 and sector 2, it is sector 0 you actually want, or am misreading the picture. PCs typically have the partition table starting at 0x1be on sector 0 Michael www.cnwrecovery.com

That is not a partition table. For one thing, the starting and ending sectors of partition 2 are located completely within partition 1, and the ending sector for partition 3 is less than its starting sector. >Here is a digital photo of the contents of sector 1 >http://web.telia.com/~u84408784/Avis/Sector_1.png > >I have not seen Svend around here in a while.

But then a DVDR doesn't boot from the hard drive, and it probably doesn't make any sense to partition it. - Franc Zabkar -- Please remove one 'i' from my address when replying by email.

Hmm, I forgot that the DVDR uP is not an x86 type. - Franc Zabkar -- Please remove one 'i' from my address when replying by email. |
