Compatibility issue between OS6 and OSX

[FrequencyX]

Hello, I am new here and have limited experience with Mac systems. My father in law uses his Mac CxII quite frequently untill recently. He received the flashing question mark error message when trying to boot into the OS.

He did not have any Apple utlities or boot disk's for attempting to repair the issue. I told him I could try to extract the data and I proceeded to take the SCSI hard drive with me and picked up an Adaptec SCSI card.

We have a G4 here at work that I hooked it up to and it detected it just fine and loaded the Disk Utility with the famliar message "We could not detect the volume etc"..with the choices initialize,ignore and continue. I tried initialize but I do not have any option to chose and First Aid will not even check the drive. It doesn't seem to really let me do a whole lot. I was assuming the OS's were using the same type of file system HFS etc..

Any ideas on how to retrieve this information from his hard drive and extract it to the G4 so I can burn a CD? There is very very critical information, and I am trying to help him out to the best of my abilities.

Any help would be greatly appreciated.

Thank you
