[Bug 548792] Re: parted fails to report partition alignment
No problem. My concern is that parted v 2.2 (included in Lucid) states this capability, and that some user will have a botched installation on a 4K sector HD or SSD. Once parted really supports the align-check, then it should be easy to code up a script for the install. -- parted fails to report partition alignment https://bugs.launchpad.net/bugs/548792 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I assume you advised to run all the commands on the SATA drive (WD15EARS) with the 4K sectors? That's what I did.

[Bug 548792] Re: parted fails to report partition alignment
Reassigning to parted since this does not have anything to do with e2fsprogs. I have the same drive and it appears that the problem is due to the drive lieing about its sector size. It reports that it uses 512 byte sectors instead of 4kb to the kernel, and parted uses the information that the kernel provides. It might be possible to have an init script detect the quirky drive and override the detected sector size, but I'm not sure. ** Package changed: e2fsprogs (Ubuntu) = parted (Ubuntu) -- parted fails to report partition alignment https://bugs.launchpad.net/bugs/548792 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
