HEar this scenario.
1. bought a new Western Sigital Caviar SE 80Gb serial ATA HDD
2. hook it up to my 2 wk old MSI KM4M motherboard. thing won't spin up. Not recognized by bios.
3. disconnect data cable and leave power cable plugged. drive spins, but obviously still won't detect (no data cable!)
4. return it to store and it work fine on their motherboard, show up in bios and everything. Tech puts jumper on drive for power management
5. Still won't detect or spin up when I returned home (see 2., 3. above). change data cable, SATA port, power cable, unplug other devices, check bios settings. no effect. mobo bios is most recent verson. I currenty have another WD 200GB SATA that has been working fine.
any ideas??
