Do you have the 360 and PC chassis connected together to share a common ground?
You did install the drivers for the Via SATA card before formatting and making the USB stick as well correct?
I always power the drive externally, makes turning it on/off for the 10 second trick easier, which I've always done around 2 seconds on. This is how I do the ms28 drive...
1. With the PC off, connect the SATA cable to the card and drive. Also connect whatever you're using to power the drive, but do NOT turn it on yet.
2. Boot the PC from your USB stick and when you get to the C: prompt power the drive on, either via the 360 or Xecuter/Xeno kit, which ever you're using to power the drive.
3. Type in mtkflash r /m /sata orig.bin OR iDump 1234567 12345 (depending on which you're using the Xtreme Boot Maker or iPrep formatted USB stick) and press enter.
4. The list of any SATA devices it's detected should come up and one will be named XTREME, at this point power the drive off, select which ever number is the XTREME one and then power the drive back on, should only take ya a couple of seconds to do it. If all that was done right it should take off and dump the FW in 5~10 seconds.

make sure your drive is connected to the master sata port and not the slave
There are no Master/Slave when using SATA ports.
