Okay, looking over the xbox360 2.6.20 kernel patches I found out they disabled ATA_TFLAG_POLLING.. maybe this could be the reason why TS-H943A can not be detected.

xenon5.patch
"This adds support for the HDD and DVD SATA controller on the xenon southbridge.

It also disables ATA_TFLAG_POLLING in libata-core, which prevented the DVD drive
from being detected. It needs to be investigated what exactly is wrong here."


http://www.ussg.iu.e...703.3/1938.html

libata: clear TF before IDENTIFYing

Some devices chock if Feature is not clear when IDENTIFY is issued.
Set ATA_TFLAG_ISADDR | ATA_TFLAG_DEVICE for IDENTIFY such that whole
TF is cleared when reading ID data.

I'm guessing all we have to do is enable ATA_TFLAG_POLLING again. Use this current patch to clear the TF. Then both Drives should be detected.

Nice finding! Have anyone tested this? If it is working, please report it to the wiki at http://www.free60.or...nel_Development
