Solved Formatting external hard drive (from mac to windows) Recover deleted files from external hard drive after formatting from windows to mac Formatting a Mac hard drive with a Windows 7.
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.
Formatting From a Mac To format a drive as FAT32 from a Mac, follow these simple steps. 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. Select MS-DOS (FAT) as the format. 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. Establishing the partition layout. 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. 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. Formatting From a PC Select your hard drive, and choose 'Convert to MBR Disk'.Here's how to create a FAT32 partition from a Windows 7 PC.
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. 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.
Formatting the partition. 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.
If you have an external hard drive or USB flash drive that you’d like to use on both Macs and Windows PCs, choosing the right file system to format the drive can be confusing. Learn a few ways to make your drive Mac and PC friendly. Need to access or transfer files between Mac and PC? As simple as this task sounds, it’s not very straightforward for inexperienced users.
Since Mac OS X and Windows use totally different file systems, the way a drive is formatted can determine what type of computer it will work with. In fact, there are four ways you can format an external or USB flash drive to achieve varying degrees of compatibility between Macs and PCs. Let’s take a look at them: HFS+ Mac OS X’s native file system is HFS+ (also known as Mac OS Extended), and it’s the only one that works with Time Machine. But while HFS+ is the best way to format drives for use on Macs, Windows does not support it.
If you’re only going to be using your external or USB flash drive with certain PCs – such as at home or the office – you might be interested in a program called. When you install MacDrive on a Windows PC, it will be able to seamlessly read & write to HFS+ drives. This isn’t a good solution if you need your drive to work on any PC without installing software, though. NTFS The native Windows file system is NTFS, which is only partially compatible with Mac OS X. Macs can read files on NTFS drives, but it cannot write to them. So if you need to get files from a PC to your Mac, NTFS is a decent option. However, you won’t be able to move files in the other direction, from Mac to PC.
FAT32 The most universally supported way to format your drive is with the FAT32 file system. It works with all versions of Mac OS X and Windows. Case closed, right? Well, not so fast. Unfortunately, FAT32 is a very old file system and has some technical limitations. For example, you cannot save files that are larger than 4GB on a FAT32-formatted drive.
This is a deal-breaker if you work with huge files. The other limitation is the total size of the partition. If you format your FAT32 drive in Windows, the drive partition cannot be larger than 32GB. If you format it from a Mac running 10.7 Lion, the drive partition can be up to 2TB. Much better, except for that pesky 4GB limit. ExFAT The exFAT file system eliminates the two major deficiencies of FAT32: the largest partition and file sizes it supports are virtually unlimited by today’s standards.
Awesome, it’s perfect! Almost since exFAT is fairly new, it isn’t compatible with older Macs and PCs. Any Mac running 10.6.5 (Snow Leopard) or 10.7 (Lion) supports exFAT, while PCs running Windows XP SP3, Windows Vista SP1, and Windows 7 are compatible. If you know you’ll be using computers running updated versions of these operating systems, exFAT is the clear best choice. Format a drive using Disk Utility on a Mac. Launch Disk Utility (Applications Utilities). Select your external hard drive or USB flash drive from the list on the left.
Click on the Erase tab. Select the format – Mac OS Extended (HFS+), MS-DOS (FAT32), or exFAT – then name the drive. Click the Erase button and the drive will start formatting.

Be aware that formatting a drive deletes all of the files on it, so back up anything important before completing this step. Format a drive using Windows. Go to Computer (or My Computer in Windows XP). Select your drive from the list and right-click on it. Choose Format from the contextual menu. A window will pop up where you can choose the format – NTFS, FAT32, or exFAT.
Make sure the allocation unit size is set to default and type in a volume label. Click Start to format the drive. I did exactly what you said to do in order to format a LaCie 160gb external hard drive to exFat for use on a Mac (OSX 10.7 Lion) and a PC (Windows 7). Unfortunately, now my Mac doesn’t “see” the hard drive anymore and my PC tells me the device is not working properly (error Code 43 in Device Manager). Before reformatting from a NTFS, the LaCie worked fine on my Mac and my PC “saw” it but I couldn’t access it. It is connected via USB 2.0 and AC/DC power. Where could I go or what resource(s) is/are available for me to solve this problem?
I heard using a firewire might help. I just got a Seagate GoFlex Desk External Drive, and after reading your article, I tried to format it for ExFat but got an error: Invalid Option. Seagate tells me that they do not support ExFat. They say “Reformatting a drive in ExFAT is something that we don’t support. It can be an unstable format that can cause data corruption without warning.” Have you found that other hard drive manufactures say they don’t support this format for the same reason? Should I turn the hard drive back in, and get a different one, where the manufacturer supports this format. Is what Seagate says true?
I just got two Western Digital 3TB external hard-drives. I want to be able to use them on both Mac & PC.
When i go to format it on my Mac, FAT32 is not an option, and every time i try exFAT i also get an “error: Invalid Option”. I then tried to do this on two other Macs & it still wouldn’t work, but then I tried it on a work-mate’s Mac today & it formatted in exFAT fine How unstable is exFAT? I don’t want to lose the media i store on this drive.
I don’t mind formatting it in FAT32, but it’s not an option when trying to format this hard-drive. Any suggestions? Is there a free formatting application that is good to use instead of using the “Disk Utility” on Mac.? I have an IMAC running OSX 10.7.5 I recently bought a Trekstor DataStation pocket light 500 GB external portable hard drive 2.5″ I need it to transfer 190 GB of video and audio files to give to an editor. I received it and a small paper inside said it’s not compatible with my IMAC. Only to READ files.
I’m not sure what system the editor will use and after reading all the comments above, I’m really hesitant to re-format the disc before moving the files onto. Now the files are on another TrekStor external drive that the camera guy lent me. I am not very technical and don’t want to screw anything up. Can anyone help?
I do hope you can help me with this I was using my sisters Mac temporarily and before giving it back to her I copied all my files onto a thumb drive. Tonight I copied those files to the hard drive of my PC laptop and removed them from the thumb drive. For whatever reason I am trying to open a few of the files in a certain program, but it keeps telling me that the file I am trying to access is not supported. Someone mentioned that maybe it has something to do with the thumb drive. I have no idea what to do and I am praying that I didn’t lose any of my files. Thanks so much!! I’ve read too many posts from people having all sorts of problems using exFAT to consider using it.
Maybe one day, but for now, “not ready for prime time!”. The best solution I found was: 1. Format your hard drive, or every partition on it, using NTSF.
You’ll end up with a drive that is: – Stable, so your data is relatively safe (priority #1) – Capable of handling large files – Readable/writable in Win 7+ – But only readable in Mac OS X 2. Make the NTSF drive both readable and writable in Mac OS X. There are different ways to do that. Method 1: Mac OS X is actually capable of writing to a NTSF drive, just not by default (don’t ask!). So you need to activate it: 1.
Go to “utilities” and start the “terminal” app. (enter your password if prompted) 2. Type (copy/paste): sudo nano /etc/fstab Press “return” Type: LABEL=TEST none ntfs rw,auto,nobrowse Press “return”, CTRL+O to save, CTRL+X to exit the terminal. Unmount your drive, then plug it back in. It won’t show up anymore. Back in the terminal, type: open /Volumes press “return” There’s your NTSF drive!
Now you can do whatever you want with it in Mac OS X. (tip: create an alias of the volumes so you don’t have to go back to the terminal every time) Another free method: “EaseUS ALL-IN-ONE Partition Manager” software I’ve not tried it myself, but I’ve only heard good things about it. You can download it here:. Make sure to download the “free for home user” version. The other methods involve using 3rd party drivers such as: Paragon NTFS or Tuxera NTFS. They’re not free, but they won’t break the bank.
I hope this helps. Thank you so much for this easy to follow and understand explanation. I have OS X 10.7.5 running Lion. Bought the new Passport 1T today and even though the package says it can run on MAC OS X, when I tried to format with the company instructions it wouldn’t let me and stated “It will only run on 10.8 or above”. I looked at my old passport in Utilities and it was formatted as NTFS (Mac OS Extended) and wanted to follow the exact same since my old Passport has been excellent for my needs. I formatted the new Passport with NTFS and it works like a charm. Really appreciate how you explained everything in simple terms, so not only was I able to do the formatting, I also understand what I am doing and why.
I can now drag and drop files on to the new passport and they copy fast. Thanks a bunch.
