'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;
$ sudo fdisk -l /dev/sdc
