I have installed a similar setup(dh55tc-i3 530) and it seems to work well with a recent build. The box is at school w/ kid and cant check the controller mode setting but am pretty sure i didnt make any changes there.. have you updated the bios to the most recent? 0036 is the latest--think i put 0035 on last--i was going with pci express if the red sata setup on the board didnt work as kids say the esata moves data faster than usb2. prolly didnt help u much but good luck....
Resolved - Sort of. The clue was the actual controller ID in Device Manager. Once I set the operational mode of the SATA channels to AHCI, the following boot replaced the 4-port host controller with a 6-Channel one.
The second part of my issue is the non-locking nature of SATA/eSATA cables. Since most external drive housings sit vertically the eSATA cable tends to pull itself loose. I finally inserted the cable tightly enough that it doesn' t pull away.A piece of "Gorilla Tape" now ensures the cable won't work itself loose again.
BUT every action on a PC has unanticipated results. Now with the SATA controller operating in AHCI mode, CD Burner XP pro no longer detects the presence of my SATA Optical drive.
Working on a computer is like untangling Christmas tree lights. Untie the 1st knot and move to the next......
Solution to CD Burner XP Pro issues was to install Intel Rapid Storage Driver Ver 9.60.1014. While not offered as part of the DH55TC drivers I downloaded from anoter Intel Series 5 product (DG45ID and it resolved my issue.
I have worried about the non-lock cables as well. dvd burner and original hdd have locking clips and the esata came with reg cable so will have to watch or just replace soon. and yes the string of lights goes on and on............
