Hi everyone, New Mac user here, and I must say I love both the hardware and OS X. However, I ran across one problem I can't seem to solve. I have an external HDD hooked up to my iMac. It's from Freecom, and I believe it contains a Seagate ST310005 disk. I formatted the disk, and set up Time Machine. It seems to go well, TM makes the first back-up without any problems. But, even though TM is turned on and set to back things up, nothing I put on my PC after the initial back-up gets backed up. I put a folder on my desktop, put some files in it, and they are nowhere to be found in the TM back-ups. I made sure the folders are not excluded from TM. Can anyone help, please? Thanks, Mark Veldhuis.
