Hi

I have an external hard drive that for some reason now does not mount to my Mac desktop, nor is it visible in Disk Utility unless I restart with "cmd + r" and even then the options for it are greyed out? It is, however, visible in the System Profiler under the USB section. Any suggestions as to how I can get this drive to mount?
This drive was previously onlt used for TM back ups and my other external HDD is still working fine?

Thanks
