First of all, as you've seen the hard way, MCSE doesn't support this drive, so you should not meddle with it.
Secondly, what makes you think that flashing another EEPROM file will cure your drive?
Unlike firmwares, the EEPROM of each drive is unique (contains unique factory calibration data), so flashing another drive's EEPROM is risky and the drive might not work very well as a result. It is always a matter of last resort. Besides, if you already have an EEPROM dump of your drive (made before you miss-flashed it) then it would be quite unlikely that your EEPROM dump is somehow corrupt, particularly since the EEPROM Utility has let you flash it back...
Anyway, here's a good CA11 dump and also an EEPROM dump from a CA11 drive as well: http://www73.zippyshare.com/v/8872181/file.html
Try flashing CA11 again using the Firmware Utility. Restart your machine. If your drive still doesn't work, then try flashing the EEPROM next. I guess you've got nothing to lose at that stage. Restart again. If the drive still doesn't work, then I guess its bricked. I can't see what else you could do ... you could try crossflashing to other OEM firmwares, but I doubt it will make any difference.
Report back and if its still a no go, I'll let you have some OEM firmwares which you could try.
