long time no see, and again i'm stepping by with a computer-issue...
i have some weird problems with my computer... it's a "hackintosh"... i guess, none of you has experience with hacks, but as this seems to be a hardware problem, this doesn't really matter...
First of all, my system:
Intel Core i5 3570k @ 4 Ghz
8GB Corsair XMS3 DDR3-1600 (2x4GB),Asus GeForce GT 640 2GB
1TB Western Digital Blue WD10EZEX
650 Watt LC-Power Silent Giant - Green Power Edition
It's a dual-boot system with both OSX 10.8.2 and Win7, each on a 500GB partition on the same HDD. A few days ago, while working with OSX, my system went slower and slower and finaly froze. I tried to reboot, it didn't work, so i started it in verbose-mode, where it stopped saying "disk0s2 i/o error" (and much more, i didn't note it).
After some research i came to the conclusion, that it might be a HDD error, but wasn't sure, because Win7 still started without any problems.
I bought 2 SSDs - 60GB Kingston SSD Now V300 - which i had planned anyway, tried several times to install 10.6.3 on one of them and it always stopped, saying that it the installation was unsucessful.
I then tried to install Windows on it and it didn't work neither until i set the AHCI-mode to IDE.
After installing Win7, i set it back to AHCI and suddenly, Windows didn't boot anymore.
Installing OSX with AHCI set to IDE failed, as i had expected.
Now it looked more like a Controller failure to me, but then i tried it with the other SSD and suddenly everthing worked fine! I got OSX 10.6.3 up and running, haven't updated to Mountain Lion yet.
This made me somewhat curious, so i plugged the old HDD in a SATA 3GB/S connector (it was in a SATA 6 GB/s before) and suddenly my old system boots again without any problems...
old HDD on SATA 6GB/s: OSX won't boot, Windows boots.
old HDD on SATA 3GB/S: everything's fine
SSD1 on SATA 6GB/s: can't install OSX, Installing Windows works only in IDE-mode
SSD2 on SATA 6GB/s: Installing OSX works fine, haven't tested Windows
Any idea what's wrong here? Do i have some weird HDD error which sometimes occurs and sometimes don't? But why doesn't one of the SSDs work, then?
Or is it a Controller Error? But why do some Disks work on the 6GB/s and some don't?
