Disk Utility starts the first partition on an MBR formatted disk at sector 63. This is a problem because:
1) There is not enough room for Grub if the OS is installed on RAID and LVM 2) Causes partition misalignment with physical sectors for modern disks 3) Causes partition misalignment with erase blocks on SSDs 4) Windows now defaults to sector 2048 so Disk Utility is behind the times 5) I cannot find any way to change this in Disk utility 6) Disk utility is the default GUI partition editor in Ubuntu I would expect Disk Utility to start the first partition at logical sector 1024 or 2048. I beg to differ that this has low importance. It can lead a user to not being able to reboot their system after an upgrade to 12.04 because the Grub core.img is so huge it no longer fits within 62 sectors if the system has RAID and LVM. THIS WAS REPORTED 1 YEAR AGO and STILL PERSISTS IN UBUNTU 12.04???? Good grief. Presumably this is an easy peasy fix so just do it, please, and release an update. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-disk-utility in Ubuntu. https://bugs.launchpad.net/bugs/802153 Title: old /wrong starting sektor on new harddrives with 4k Status in “gnome-disk-utility” package in Ubuntu: Confirmed Bug description: When creating a new partition on an empty hard drive, the starting sektor is 63, not as it should be now 2048. # fdisk -lu /dev/sdb Platte /dev/sdb: 2000.4 GByte, 2000398934016 Byte 255 Köpfe, 63 Sektoren/Spur, 243201 Zylinder, zusammen 3907029168 Sektoren Einheiten = Sektoren von 1 × 512 = 512 Bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0007d0f0 Gerät boot.

Gparted does use starting sektor 2048 as well on standard settings. The fix should be: change the starting sektor on a new partition to 2048.
