Mint 5 was running perfect on my old hard drive.
My son bought me a new hard drive for fathers day so I copied my mint 5 on to it from my old hard drive using Acronis Backup.
Everything is working great ,but, if I go into Partition Editor swop is off !
I have to go in and turn it on Manually in Partition Editor each time I restart my computer.
How do I fix it please?
Swap off !

Look in your file system and post a copy of your /etc/fstab file. Also post the output of from a terminal.

Re: Swap off !
That looks normal. I thought maybe the partition numbering had been altered when it was copied to the new HD. You can check to see if it is being used with Also try turning it on with See if these commands give you any relevant errors. Check with the partition manager to see if the swap partition is active, and what flags it has(right click on the partition). If none of that gets you any closer, then probably the easiest thing to to would be to use a live CD and the partition manager to just deleted and recreate the swap partition.

cat /proc/sys/vm/swappiness

sudo swapon -a

Re: Swap off !
Also its worth verifying the UUID (ubuntu based systems use UUID instead of partition numbers)
from fstab:
# /dev/sda6
UUID=c07ff63a-1b38-4d06-a2b5-432d0ada70aa none swap sw 0 0
Just the swap partition still has the same UUID (run vol_id /dev/sda6, probably as root), If they are not same, update the entry in fstab with correct UUID and try. If not , you can try out 67GTA's suggestions

I restarted the computer with the cd ,deleted the swap file , re installed it.
turned computer off then on again ,went into partition editer the swap file is turned off !!
I have to click on swapon to turn it on.

Re: Swap off !
You might have some UUID issues, edit fstab and change the UUID to /dev/sda6 (assuming that is the swap partition).
Re: Swap off !
I think MagnusB and rbanavara have it right. Open a terminal and run This will show you the UUID of your partitions. Check your UUID for sda6 against the one shown in fstab. MagnusB has the best solution for fixing that.

Re: Swap off !
Thank-you very much for your help ,you've solved my problem
the UUID'S were different, edited the fstab one and everything is OK now.
Best wishes
