nosammai Posted June 24, 2012 Share Posted June 24, 2012 I installed a second hard drive into my Alienware M14x by replacing the optical drive with a caddy. I installed lion on the second hard drive, and it boots fine, but it's really slow after it boots. Sometimes when I click on anything, it just hangs for about 10 seconds then loads, but it's pretty inconsistent - sometimes its fine, sometimes it hangs. It's odd because I had lion working perfectly fine in the primary HDD bay, but when I move it to the optical drive caddy, it's slows down. I was having this same problem in Windows, but I fixed it by installing Intel's Rapid Storage Technology drivers. Is there some sort of equivalent Kext, or something else that I should be doing to make it work properly? System Information says it's got an Intel 6 Series chipset. I know the optical drive port is only SATA 1.5 Gbps, but I don't think that should really affect it as much as it is. Link to comment Share on other sites More sharing options...
nosammai Posted June 24, 2012 Author Share Posted June 24, 2012 I got everything else working(QE/CI, Ethernet, sound, USB, PS/2), but I can't seem to figure this one out. It's not that the disk is getting slow transfer speeds - they're up where they should be for a SATA 1.5 Gbps HDD. I opened up Activity monitor to look at the graph for disk activity, and it looks like there are spikes of I/O (Of normal speed) separated by valleys of 0 I/O. The spaces are all similar in length. I also did a benchmark in OSX on the HDD and it came out normal. Again, I was having almost the same issue in windows that was solved by installing the Intel RST driver, but I'm not sure what the equivalent would be in OSX. I've been going at this for about three days now, and it's getting really frustrating. Any and all help/suggestions would be greatly appreciated!

3.14r2 Posted June 25, 2012 Share Posted June 25, 2012 What chipset and south bridge the PC has? Are both drives using the very same disk controller? Link to comment Share on other sites More sharing options...
nosammai Posted June 30, 2012 Author Share Posted June 30, 2012 I believe it has the Intel HM67 Chipset Link to comment Share on other sites More sharing options...
xplus93 Posted March 6, 2013 Share Posted March 6, 2013 I know this is old, but the ODD uses SATA I/1.5 compared to the SATA II/3.0 of the HDD. Hope this helps, just use the secondary drive for storage space and you'll be fine. Link to comment Share on other sites More sharing options...
