I gather that you had no backup copies stored in another location? That's unfortunate and the data may be all that you can recover. It's likely that the drive failure damaged the copy you had--was it open at the time it failed perhaps?
This is the software they used http://www.ufsexplorer.com/
If you have the hard drives, it may be worth the time to try another recovery.
If they are SATA drives and your computer is a desktop and has SATA connections, install the drive.
If you can not install the drive, you can buy a SATA to USB converter. http://eshop.macsales.com/item/Newer%20Technology/U2NV2SPATA/
If it is partitioned and formatted for Linux - ext2 or ext3, the fastest simple attempt would be to boot your computer with a Linux Boot CD.
PuppyLinux is small, simple and free. http://puppylinux.com/
If the drive is not recognized or files shown, another method can be used.
If the drive is not FAT or NTFS formatted, you need to use a utility that can read other formats or is looking at the structure of the drive and not the file system.
TestDisk or PhotoRecover are often used. http://www.cgsecurity.org/wiki/TestDisk
DataRescue 3 is another utility I use, though the scans can be time consuming. The demo will scan and allow one file to be recovered, tested, before paying to unlock the software. http://www.prosofteng.com/products/data_rescue.php
I would focus on backups rather than the current database, if they exist on the drive.
There are better backup strategies than the one you were using.
