Best format for external drive readable in OS X and Windows?

I have an external drive that will need to be connected at different times to both my Mac (Leopard) and my Windows XP & Vista machines. I had it formatted for Mac OS (Journaled) but it wasn't readable in XP or Windows.

So what is the best format so that all can read/write to it normally? NTFS? It needs to be able to handle larger files (4GB and bigger).

If it needs to be able to handle large files than your only choice is NTFS. However, just know that OS X only supports reading and not writing to NTFS drives.

Crap. Thanks for the info though.

Is there a way around this? Could I partition the drive so that when the drive is plugged into the Mac I can move files onto the Mac partition, then move the file to the NTFS partition? And if so, would I need to plug it into a Windows computer to be able to move from once partition to another?

The drive is being formatted to work with this so I'm not sure that will work. I will be creating and transferring files on the computers then connecting the drive to this device to view them.

If the Mac is only machine and PCs are numerous, then make it NTFS and get Paragon NTFS for Mac (read/write).

If the PC is singular, and Macs are numerous, then make it HFS+ and install MacDrive on the PC (allows read/write of HFS partitions)

The best bet for most uses is FAT32 file system. For more security, other file systems are available, but you need to get third party software in order to allow windows or mac to read/write respectively.

NTFS (Windows NT File System) is the most advanced Windows system, developed for NT, and used in windows NT, 2000, XP & Vista. Macintosh systems can read NTFS, but cannot write to it unless third party software is installed. This software may come at a price (usually around $25-$30)

HFS+J (Mac OS Extended (Journaled)) is an advanced Macintosh file system that is probably the most secure way to go, however Windows systems cannot read or write to this file system unless third party software is installed.

FAT32 is an old windows file system that is used universally among many devices. This file system also has a size limit of 4GB. It can store many files as long as each single file is less than 4GB. On Windows VISTA, you cannot copy groups of small files totaling more than 4GB at a time. Macintosh and Windows systems, as well as other systems like Playstation 3 can Read and Write to FAT32 without third party software. There is no third party software available for Ps3 to date.


Here are some Third party Software choices that have been suggested my other macrumor members. I will recommend Paragons NTFS for mac, as I have tried it, and it worked for me. I was able to access an NTFS drive, remove important files, and then format it.


MacFuse & NTFS-3G

Paragons NTFS For Mac

Mac Drive (For Windows)



--------------------------------
Format Instructions:

Open Disk Utility (HDD/Applications/Utilities/Disk Utility.app)

When it opens, select the the External drive from the side bar, then select the "Partition" tab in the main window.

From here you can select how many partitions you want. If you wish to use the entire drive, select 1 partition. Under "Volume Information", enter a name, and select a file system. For FAT32, select "Ms-Dos File system".


You can now click the "Partition" button in the bottom right hand corner.


Small USB sticks may require an extra step in order for OS X to format it as FAT32. Their small size makes the OS format it as FAT16 (also ms dos).

To format a USB stick properly, follow the above steps, but before clicking "Partition" click on "Options..." and make sure "Master Boot Record" is selected.

FAT 32 is probably the most convenient trouble free format...

That is if you can live with the 4GB limit.

Right. The link above is to a WDTV device that I was using with it (I have since switched to the PopCorn Hour) and almost all of the files are over 4GB, so that wasn't an option.

I ended up going NTFS and installing the Mac software to let me r/w to the NTFS drive.

I've actually had a lot of problems with drive formatting and mounting with the PopCorn Hour, though not by any fault of the PCH device. I preferred to use the internal drive option, which formats the drive as EXT3. There is an EXT3 driver for OS X but it's older (2006 I think) and does not work with Leopard. I ended up installing VMWare Fusion on the Mac and handling file transfers either via Windows XP or through wifi file transfer (which is slllloooowwwww).

So by installing this mac drive on Windows, I can insert my Mac OS formatted harddrive in my windows comp and I can both read and write files on it?

Does it cause any problems?

Thanks i.shaun, that's is all very useful information!

I have a 1TB iOmega external drive that I want to use on my Macbook as a media file backup destination, then hand it off to my friends XP machine. I am going to point him to "Mac Drive" as a solution.
