HSFX is Mac OS Extended with case-sensitive file names. Run HFSExplorer (we're using Windows 7 64-bit here and it works fine) and ignore any message that a DLL file is missing. If the Mac OS Extended partition is not Journaled, please journaled it first. Run Disk Utility, select the Mac OS Extended partition in the left column, then select File and select Enable Journaling. In general, you’ll want Mac OS Extended (Journaled). You can use (Journaled, Encrypted) to encrypt the entire drive. However, this will make them a tad harder to work with in Disk Utility and won’t allow other computers to access the files.

I have a shared directory on a Mac Server that I want to map to my Windows 7 PC.

It worked fine on the old mac server as the hard drive was formatted as NTFS, but on this new one (which we got yesterday) the hard drive is Mac OS Extended (Journalled) and it's not happening.

Does anyone have any experience in this area?

Thanks

I don't know what you mean when you're talking about mapping the drive and how its formatting affects it. Typically if it's actually mapped over the network, it doesn't matter (other than with permissions).

If you want to share a Mac-hosted directory to a Windows system, use Samba (which is used for filesharing anyway.) Samba abstracts the permissions and filesystem from the clients. That's also why when you share drives from Windows you have sharing permissions AND file ACL's (from NTFS).

What you'll lose in sharing from the Mac is the finer ACL control from NTFS, since you have to use UNIX permissions to control file-level access. Or play with SAMBA permissions mapped to the Windows user for access control. But it works fine.

Otherwise you'll have to post details on what you're doing and why it isn't working (procedure, error messages, etc.) As posted your description is extremely vague.

Looking to share an external hard drive between a Mac and PC? The best way to do it is with a drive formatted as FAT32. Though this format has some limitations, it enjoys nearly universal support from active platforms, including Mac and Windows operating systems, and many gaming and Linux OSs.

The chief drawbacks of FAT32 involve file and partition size limitations. FAT32 imposes a size limit of 4GB on single files. So if you work with bulky video clips, for example, adopting FAT32 may not be a good idea. When formatting partitions, Windows 7's Disk Management utility won't let you create one that's larger than 32GB, whereas Mac OS X Lion can create partitions as large as 2TB using its Disk Utility application. Finally, Mac OS X's Time Machine backup utility won't work with FAT32.
Windows prefers to use NTFS (which stands for New Technology File System, though it has been around for nearly 20 years now). Macs running Snow Leopard or Lion can read from drives formatted as NTFS, but they can't write to such drives unless you install a third-party driver or muck about in the Terminal. Conversely, Windows 7 can't read and write to drives formatted as HFS+--also known as Mac OS Extended (journaled)--unless you install third-party software such as Paragon's.

Formatting From a Mac

To format a drive as FAT32 from a Mac, follow these simple steps.

1. Set up your drive following the manufacturer's instructions. Connect the power supply (if necessary), connect to the Mac via USB or FireWire, and turn on the drive. The drive should automatically mount on your Mac's desktop (if the finder preferences are set to show external drives). If the drive is not formatted, you may get a message saying that the drive is unreadable by Mac OS X and asking you whether you want to format it via Disk Utility. We're going to do this anyway, so open Disk Utility from the prompt or by navigating to /Applications/Utilities.

2. Mac OS X won't let you create a FAT32 partition larger than 2TB; so if your drive is larger than that, you'll need to divide the available drive capacity into multiple partitions. You can format the remaining space as a second FAT32 partition or as an HFS+ partition, or you can leave it as unallocated space. To create a new partition, click the drive in the list on the left side of the Disk Utility menu. Click the Partition button in Disk Utility's main window. By default, Mac OS X will use the GUID partition table to format the drive. You can use this and still share FAT32 volumes with a PC, but if you'll primarily be using the drive with Windows, and if the full capacity of the drive doesn't exceed 2TB, the wiser course is to wipe the drive and then use Windows' Master Boot Record (MBR) partition scheme.
3. Click the Partition Layout drop-down menu in Disk Utility, and select the number of partitions you want to create. By default, Disk Utility will divide the available space in half. You can resize the partitions by clicking the line between the partitions and dragging it up or down to increase or decrease the capacity of one or the other side.
4. Click on whichever partition segment you want to format as FAT32. Type a name for that partition in the Name field and choose the FAT32 option from the Format drop-down menu. Once everything is arranged as you want it, click apply. A progress bar will appear at the bottom right of the window as Disk Utility creates the requested partitions. Once it finishes creating them, you can move the drive between Macs and Windows PCs, and move files back and forth easily.

Here's how to create a FAT32 partition from a Windows 7 PC.

1. Open the Disk Management utility. To do so, select Start, Control Panel, System and Security, Create and format hard disk partitions. Alternatively, press the Start button and start typing partitions.

2. Find the drive you'd like to format; in my case, it was Disk 5. Click the disk number, and select Convert to MBR Disk ('MBR' stands for 'Master Boot Record'). Right-click the unallocated segment in the next field over, select New Simple Volume, and click Next when the wizard launches. Change the value in the Simple Volume size field to 32,768MB or less--it needs to be under 32GB, to satisfy the format's file limit. Assign a drive letter, and click Next.

3. Choose the drive letter to be assigned and click Next. Select FAT32 from the File System drop down menu, label the volume however you like, check the box next to Perform a quick format, and click Next. The resulting window tells you that you have successfully completed creating the volume. Click Finish and you're ready to go.
