disk no longer readable. Intialize doesn't work

[stunt monki]

Hey.
I'm using a new i-mac and one of my external drives no longer is readable on the Mac. I can't do a disk repair or verify. I just get this message.

Verify and Repair volume “Monki 1”
Checking Journaled HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Invalid record count
Invalid record count
Volume check failed.

Error: Filesystem verify or repair failed.

I'm running OS 10.5.7
Does anyone have any suggestions?
It does say it is online.

DiskWarrior. The end-all, be-all of disk repair programs. If it don't work on your drive, nothing short of a very expensive, professional data recovery service will be able to do anything to it.

This finicky drive -- is it your boot drive?

I have an older copy of Disk Warrior. My Mac will not boot up from that disk. It is an older copy, that may be the problem there.
The finicky drive is not my boot drive. It is an external drive that I mirror raided and use for video.
Do you have any thought or on prosoft's data recovery II? That one also is supposed to be really good.

You mean Data Rescue II? Its a good program. Should find whatever is on there provided the drive has not been overwritten or the drive hasn't failed. I think they have a deal going where you can try it out and it will recover a limited amount to see if you want to spring the $100.00 for the full version.
