Hello, can any tell me, why the GPT Table is broken by a linux installation I have a dual boot system, the GPT Table is created with Win "diskpart" This is a (U)EFI installation. With linux kernel 3.5.x, I have always this message in the log Sep 17 09:54:27 techz kernel: [ 1.204681] GPT:Primary header thinks Alt. header is not at the end of the disk. Sep 17 09:54:27 techz kernel: [ 1.204685] GPT:625137663 != 625142447 Sep 17 09:54:27 techz kernel: [ 1.204687] GPT:Alternate GPT header not at the end of the disk.

Sep 17 09:54:27 techz kernel: [ 1.212404] sda: sda1 sda2 sda3 sda4 sda5 sda6 When I like to repair this with parted the system is not booting and the Raid1 is destroyed. -- mit freundlichen Grüßen / best Regards.
