greetings.

centos 6.7 [current]


'disk utility' has started showing message;

  WARNING: The partition is misaligned by 2560 bytes. This may
  result in very poor performance. Repartitioning is suggested.

for sdc5 - /home partition.

  /dev/sdc5      302243312 156348604 130534968  55% /home
  /dev/sdc7       80854912     57088  76683952   1% /hdd/c/07

other than time involved to backup sdc5, repartition is not a problem.

to my thinking, but not recalling,  with fsck;

  fsck -rN -t ext4 /dev/sdc5  * to check repairs
  fsck -r -t ext4 /dev/sdc5   * to repair


gparted was used to partition drive. is pmagic live a better choice,
or should i return fdisk because;
