I have a WD160gb SATA for the master and a Maxtor Diamonmax Plus 9 80gb for the slave. I'm recovering the files from the IDE drive. (Corrupt XP files) SATA = no jumpers IDE drive is no jumpers for slave mode When I hook both up, the machine tries to boot from the corrupt IDE drive. The maxtor drive is connected to the secondary plug on the ultra ATA cable and I've switched SATA ports. I have no clue what the issue could be until I thought of a 'switch or something that would configure to either use the SATA or IDE for master the master drive. I've got this mobo... http://www.biostar-usa.com/mbdetails.asp?model=p4tsv ...and and right next to the SATA ports there are more pins that have jumpers. Could it be the reason why it's booting from the IDE?
