I have an interesting problem.
I recently upgraded from 80Gb to 250Gb HDD in my netbook using:
dd if=/dev/sda of=/dev/sdb bs=64k conv=notrunc,noerror
and using gparted to expand the partition afterwards.
This worked perfectly.
I found that the new HDD used much more power than the old HDD, reducing run time to an unacceptable level.
I bought a 128Gb SSD, with which to replace the new HDD.
I used gparted to shrink the partition from 250Gb HDD to 120Gb, and recreated the extended/swap partitions.
I then used dd to copy this image to the new SSD.
This seemed to work: the netbook boots fine and all works well, except when I try to use gparted to expand the partition to the full 128Gb. Gparted reports all the space on the SSD as "unallocated", even though Disk Utility shows the 120Gb ext4 & 4Gb extended/swap partitions.
I used gparted to shrink the HDD partition to around 80Gb and tried again, but the result is the same: gparted reports the entire disk as "unallocated" and I cannot expand the ext4 partition.
Any ideas?
