Feature changed by: Greg Freemyer (gregfreemyer) Feature #312273, revision 3 - Title: fix bug in yast disk + Title: Update yast-partitioner GUI to reflect they way it works + internally openSUSE Distribution: Unconfirmed Priority Requester: Mandatory Requested by: Andrew Joakimsen (joak0) Partner organization: openSUSE.org Description: Summary Description yast-partitioner was updated for 11.3 and newer to stop using CHS information as its primary partition alignment strategy. The user interface was never updated to match. The user interface for yast2-partitioner should be updated to allow the user to select legacy CHS presentation and the more modern presentation units of sectors / MBs / GBs or other units more appropriate to raid strides.

If you'll post the openFATE link to your proposal, I'll add my vote.
Greg >> > The current functionality is a bug and I have long ago reported it as such. Disks are addressed by logical sectors this millenium. It's a bug to show an obsolete, not-convertible unit. serves no purpose unit. The fix to that bug is to show the relevant unit. -- Med Vennlig Hilsen, A. Helge Joakimsen
