I am currently having an issue on my G5 at work where if the G5 has been on for a while and I try and plug in a USB 2.0 External hard drive or Jump drive it will not mount. I have checked the System Profiler and it shows a USB2.0 Storage Device listed there. I have tried the command line to look for the volumes and I have also tried disk utility and it does not show up in either place. If I restart and have the drive plugged in or plug it in shortly after the system has been started it shows up just fine. Anyone have any ideas on how to rectify this. The system in question is a 1.8 Single Processor G5 PowerMac with 1GB of RAM. Thanks.
