    Since switching to Mac I haven't been able to edit anything on my externals. I can copy data onto it, but nothing else. I've just noticed that I've formatted it to NTFS, is this why? Do I have to re-format in FAT32 (I think that's it's name), the reason why I formatted to NTFS when I was using windows was because I wanted to transfer files over 4gb, how do you guys do this on a mac? If that's the problem.

    Macs do can write to NTFS out of the box. If you want to transfer large files you are correct: FAT32 will not work. You could install MacFUSE and NTFS3G (Google will help you find these) and get write access to NTFS from Mac OSX. It's free...

    Yes, NTFS is why.

    If this external is only to be used on a Mac, format it as Mac (using Disk Utility), its more efficient, and means you dont need to defrag it ever. (obviously (?) reformatting will wipe whats on it now)

    If you'll be switching the drive between Mac and PCs , search for NTFS in this forum and you'll see pointers as to the drivers you need to install to be able to write NTFS as well as read.

    If I format it as Mac does that make it a FAT32 drive? If so, does this mean there will be the 4gb transfer limit?

    No, FAT32 is a Microsoft format. Native Mac is HFS+. It does not have a 4Gb limit but it cannot even be read by Windows (as Microsoft choose to only implement their own formats). You can install MacDrive on Windows to read/write HFS+ but it's not free.

    I think you're best option is to follow the suggestions I made in my first reply.

    Format to Mac OS Extended (native OS x format) and on you Windows machine install MacDrive. This way your Windows machines can read/write to an OS Extended drive with no problem.

    Microsoft will not license NTFS to Apple or anyone else. However Apple will license their format to other manufactures.

    I don't understand what you are saying. Out of the box OSX can read NTFS but not write.

    I changed what I was writing half way thought and cocked it up. Macs can actually write to NTFS out of the box, but it's turned off which was why I changed what i was writing…

    Searching hard drive connected to Airport Extremeover network=no results! help!

    I have a LaCie hard drive attached to one of the USB ports on my airport extreme. I don't use it for back-ups, as I use an iomega drive for that, but simply storage of extra files. The odd thing is that I can't seem to search the drive over the network from my laptop. Yet when I connect the hard drive directly to my laptop, it works just fine.

    I have enabled file sharing in airport utility. Also, I just noticed that while my Epson printer is connected to the other port and I can use it just fine from the print menu, it doesn't show up under the printer menu on the airport utility.

    This drive is mac-formatted, but I thought I'd pose this question here, as many of you seem to be knowledgeable enough to figure this out.

    Any ideas?

    Thanks!
