It's not bricked. You can't really brick a Moto Droid because there is a file called SBF that you can use to reset the phone pretty much no matter what as long as it isn't physical or water damage. But, this happens sometimes through Rom Manager for some reason. I fixed this by flashing the other recovery, and then flashing back to ClockworkMod recovery. I find it generally more reliable to download the zip on the computer and put it on the SD card and then flash it through the recovery that way. If you did a Nandroid backup as well, you just just pop out your battery and reboot into recovery via holding the "X" on the physical keyboard and power, then you can restore your backup there. If you did not make a Nandroid backup for some reason, it's still ok. Just reboot into recovery and go to Partitions. You can then mount your SD card to your computer and put another rom on there and then wipe both the factory data and dalvik cache, then flash the new zip, reboot, and enjoy.
