Hi I have a weird problem that occurred today that's got me completely boggled. Any help would be much appreciated. I appologies for the vagueness at times, I could only post now because my internet's been down thanks to Telstra (hense why I tryed using their wireless service, which would seem screwed my Hard drive. yeh!) I installed a small application from Telstra (main telecommunications company in Australia) that allows you to connect via a USB modem to the internet wirelessly. After completing the installation, it prompted me to restart and I did so. However, before it shut down a dialogue came up saying it had to clear/reset the system cache or something like that. I clicked ok (only thing i could do) and my computer restart as normal and I had internet. The problems started when my time machine tried to backup; where it stopped while "preparing to backup" and came up with an error dialogue saying something like Time failed because it couldn't find the directory. I restarted my mac once more without the USB modem attached and tried the backup again, whereby i new error came saying it couldn't mount the drive. One more restart later and I now have a Time Machine that doesn't backup or see prior backups, and a Hard Drive that not only can't be mounted but isn't recognised as even a Media device by Disc Utilities. I have no idea what's going on so any help whatsoever would be much appreciated. EDIT: Forgot to add, I tried deleting the program but couldn't because the file "Mac_Swapper_Demon" was in use. I went into Activity Monitor and there was the process. I stopped the process and was able to delete the file. Until now, i've never come across this process.
