So I got this warning in disk utility that the partition is misaligned and it may result in very poor performance. I can't tell whether the drive is performing well or not because it's a new one and it's certainly faster than the 8 year old HDD I used to use. I've just created new partitions and installed operating systems. I've created partitions using gparted on debian wheezy on old HDD. Then I have installed debian on already existing empty partitions created by gparted. I'm not sure, but I think there was no warning at this point, although I don't remember if I checked disk utility. I had to do a reinstall due to graphics issue. I reformatted partitions using utility in debian installation. I think this could cause this. Now I don't know should I leave it or erase all and start all over again. I won't lose any data because it was copied from old HDD , but a little time for sure.
I've tried to remove empty space in gparted by resizing partition but it resulted in an error. Is there a way to fix this without formatting?
HDD is Seagate Barracuda 1TB.
90GB free space is left for future installations
