Hooboy, this was rough going for me. I didn't want to crack my case open and hook my 1tb Seagate direct so I dug out my Kingston SNA-DC/U enclosure and prepped it for GPT and ExFat at to test this out. Like a moron, I blew 2 hours installing all my games from a backup instead of just a few games because I was really hoping I could replace my 640GB with HDD-OSD 2.0 with this. My experience was pretty horrendous. It took forever to get my HDD detected, and once detected, it took over 30 minutes with the spinning icon for my games list to show up. From there art work was slow loading and while every game I tested worked fine, it took over 3 minutes to get passed "saving config", and the game loading. After an IGR, it takes over 1 minutes for this build of OPL to load. Just very very slow and sluggish, and my Kingston SNA-DC defaulted to formatting this drive with a 512k sector size and that was a definite factor. Then when I went to reinstall the previous drive, I ran OPL ExFat by mistake and it never booted. Just chewed on the HDD and after 20 minutes, I put a stop to it. Launched the lastest mainline beta and all was well. Alas, that's all the testing I can do - I've done packed up my PS2, PS3, and Xbox 360. I need to put everything in storage and be out of this apartment in 2 weeks ... Gotta spend the weekend packing up and finding shelter somewhere ...
