Hi All, Slightly OT as this is on a Centos 6 system I'm getting the fdisk message "partition does not start on a physical sector boundary" on a 4096 sector disk. I understand why this has happened. I just want to be sure of my parted syntax before I really mess things up. (before anyone says it - I know - do a backup) parted says that the offending partition 5 begins at 512 byte sector no. 462999615. Its the first partition in the extended partition that begins at 462999552. If I just want to move the partition back to the nearest 4096 boundary, which is 462999608, would the syntax be unit s move 5 462999608 Will parted sort itself out copying sector nos 462999615 to 462999608 and then 462999616 to 462999609 and on an on? Or will it not cope with jiggling the partition down the disk by 7 sectors? Thanks Ken -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
