Hi threre..

Well I have a serious issue which i tried to resolve or get any insights on it on insanelymac and others but I wasn't lucky enough to be able to solve it. so I hope I may get a little help here...

my mainboard is ga-p31-ds3l, its a gigabyte, and it does not support AHCI, so i use the Combined or Enhanced mode
so both the sata and pata disks are able to boot.

the sata controller is ICH7 .. it should be compatible out of the box. still..
my problem is that using any sata harddisks in my hackintosh produces recurring disk I/O errors in the console at random times, till it ends up damaging the disk directory which finally leads to giving me the error: invalid node structure in the disk utility.., and if i try to do a surface scan on the disk it reports bad blocks due to the I/O errors..

still my IDE drive working without a problem. it seems that its only related to sata controller ?

anyway i tried hocking my sata drives with a sata to usb adaptor.. to my usb ports and boot from it... and surprisingly, those problems does not happen anymore, and also surface scans does not report any bad blocks.. so now I am sure that the disks are fine.. so the problem now relies in the sata controllers!

I didn't install windows before on this mainboard using sata hdds.. so I don't know if this is a problem with the mainboard sata controller or is it related only to osx86!

so I am not sure if the problem was related to the mainboard controllers what would windows OS react to this issue hence it uses a different format table... etc..

I was hoping if anyone have any insights that could help me identify the source of the problem.

thanks to you all in advance.
