'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.

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;

suggestions for correcting above boundaries also appreciated.
help needed and greatly appreciated.
check it with:
blockdev --getalignoff /dev/sd
(if a '0' is returned, the partition is aligned)
-- LF
