I bought a new WNDR3700 router a few days ago and since it has a USB port to add network drives, I decided to buy an external hard drive (WD Elements) to use with it for Time Machine since I was living dangerously by not having backups of my important files. I plugged the portable drive into the router to test it and it showed up in the network at first; but afterward I reformatted to HFS+ for Time Machine. After reformatting, it no longer shows up in the router. I am guessing it is because it was originally formatted NTFS and the router must not support HFS+. Is there a downside to reformatting to FAT32 so I can use Time Machine wirelessly? (I did some searching before and found that I would need to use FAT32 to get it show up with the router, but I don't know anything about file systems). Or is there any other way to get the WNDR3700 to recognize a drive formatted HFS+? Edit - Hmm, after doing more searching it looks like FAT32 can't have partions larger than 32GB, so I guess that won't work for me. Any WNDR3700 users using Time Machine wirelessly have suggestions?
