An IDE to Serial ATA converter is designed to convert a standard IDE drive for use with a serial ATA interface.
Intel does not support the use of IDE to serial-ATA converters, however limited testing indicates that such converters may work with the Serial ATA feature of Intel® Desktop Boards. The IDE drive may need to be configured as a SINGLE drive (usually by setting a jumper). The drive may not be recognized by the system if it is set as Master, Slave, or Cable Select (CS).
Had the same Problem ,,, DG31PR MoBo + E5300/2.6GHz/dual wouldnt run a PATA with a SATA converter ,,, So I went and bought a new 320GB\7200 rpm SATA2 was only $54 can ( 1 tera is only 117 can),, as soon as I hooked it up to the sata 0 on the MoBo my old PATA HD worked with the converter I had bought for it set cable Select in the 1slot lol , funny thing is I bought a GIGABYTE MoBo with same E5300 chip and had the exact same problem with it too
