Advanced Format Hard Drive with CentOS 6.4


I installed CentOS 6.4 on a new pc that has an advanced format hard drive. The results of an "fdisk -l" command report that my partitions do not end on a cylinder boundary. Is this going to cause me any trouble? Is there any way to fix this? thanks

This link should help.

There is a section for linux. parted is the tool to align the partitioning correctly.

There is a performance hit with incorrect alignment. I have read several articles indicating pre-mature disk failure if you do not align the partitions correctly. I have no proof of that, however, I do have one dead WD 1 TB ears drive that is 100% read only. It was not correctly aligned.

No problem whatsoever. While it can be important that partitions start on properly aligned boundaries (which, BTW, have absolutely nothing to do with the fictitious CHS geometry), where those partitions end is of no consequence whatsoever. Furthermore, when partitions are made with the recommended sector units and 1-Megabyte alignment, it is pretty much inevitable that they will neither begin nor end on the "cylinder" boundaries that fdisk likes to complain about.
