I've tried goggling but nothing seems to be working.

Could someone give me a step by step tutorial on how to do this, please. I'm trying to get rid of my lagspikes/freezes.

Were you Googling or Gargling? When I enter how do I downgrade Seagate Momentus XT firmware from sd28 to sd26, the first hit (http://forums.seagate.com/t5/Momentus-XT-Momentus-Momentus/firmware-downgrade-Momentus-XT-500GB-ST95005620AS/m-p/159984) contains step-by-step instructions for the procedure. Admittedly, these appear somewhat tricky to follow.

I recommended you try this in a previous thread to confirm if the SSD portion of your hybrid hard drive (SSH) had failed, since the SD26 firmware supposedly disables the SSD caching of that drive. I recommended if SD26 confirmed your SSD caching was defective, you could then contact Seagate for an RMA.

In http://rog.asus.com/forum/showthread.php?26531-ASUS-G73JH-Skipping-Issues&p=221720#post221508, you reported you replaced your SSH with a HDD and eliminated the freezes every few seconds when gaming, another way of confirming your Seagate hybrid SSH is defective. So you should now be able to RMA to Seagate (unless they claim you have to RMA to ASUS).

As I understand it, if you use SD26 to work around your freezing issue, you will reduce the disk performance of your SSH to that of a normal HDD. Is that what you want? You already stated you didn't like the slower performance of the HDD in your previous thread.

I haven't confirmed that performance drop myself. I don't own any Seagate hybrid drives, it's just what I have read. If you'd like to confirm if it is actually true, I recommend you post a thread on the Seagate forum to clarify any questions you have concerning the firmware downgrade to SD26.
