Well, first, go into Device Manager and check to see if there is an IDE channel [Primary/Secondary Channels] that’s not in at least UDMA mode 2, ideally with all devices in UDMA mode 4 or higher. The LiteOn should be in UDMA mode 4. Then, if you find any channel with a device not in the proper DMA mode [except the channel with your main booting hard drive], uninstall it and reboot your system. The channel should be reinstalled, along with any device on it, and should install it with the proper DMA.
When bitsetting, did you try to use the option ending in EEPROM in ImgBurn? That option would put your choice to bitset in the drive’s memory, and it would be permanent.
