Actually I booted with the Windows XP install CD and when it got to the partition listing to install/recover the type said 'unknown'. I am using NTFS-3g in uncached mode (all the defaults after an install). It may have crashed awhile ago. I can still access the drive in Mac OS X, I just can't boot it if I switch to windows. Could someone please help me. When I plug a NTFS drive into my Mac it’s recognised but I cant save files onto it. I can’t reformat the drive as it’s also shared with my families and friends Windows computers. How can I save files onto the NTFS disk. Thank you for any help you can give.

Summary: This post will show you solutions to fix the Mac not recognizing internal hard drive issue. Also, you can learn how to recover lost data from unrecognizable Mac internal hard drive with data recovery software for Mac - iBoysoft Data Recovery for Mac.
Usually, the internal hard drive is the startup/boot drive for a Mac. It not only loads the operating system but also is responsible for storing data. Therefore, it is frustrating if your Mac doesn't recognize the internal hard drive and you can't access the data on this drive. What's worse, when Mac can't find the internal hard drive, your Mac is unable to turn on.
Luckily, according to your situation, this article will provide 4 feasible solutions for you to fix Mac not recognizing the internal hard drive.
Scenario 1: The internal hard drive can be recognized by Disk Utility
If your Mac doesn't recognize the internal hard drive, you can check if you can find the hard drive or not in Disk Utility under Recovery Mode. This really matters because if you can see the drive but the internal hard drive is not mounted in Disk Utility, your internal hard drive has no hardware problem and you can try the following solutions to fix your issue.
- Repair the hard drive with First Aid
- Try to boot Mac in Safe Mode
- Recover lost data and erase the unrecognizable internal hard drive
- Replace the internal hard disk if it's dead
Solution 1: Repair the hard drive with First Aid
macOS Recovery is part of the built-in recovery system of your Mac, from which you can get to macOS Utilities to repair certain logical errors of the internal hard drive. The issue that Mac doesn't recognize the internal hard drive could be fixed with First Aid under Recovery Mode.
- 1. Restart your Mac and immediately boot into macOS Recovery Mode with the following steps, then release the keys when you see the Apple logo or 'Loading Startup Options'.
- 2. Get to macOS/Mac OS X Utilities, select Disk Utility, and then click 'Continue'.
- 3. Select the internal hard drive that Mac doesn't recognize, and run First Aid to check and repair errors in this drive.
Solution 2: Try to boot in Safe Mode
If the internal hard disk drive is not found by Mac, booting Mac to Safe Mode can check the errors in the directory of your internal hard drive. To boot in Safe Mode, you need to restart the Mac and hold 'Shift' immediately, and release it until you see the login window. When you see a 'Safe Boot' message on the startup window, you can restart the Mac.
Solution 3: Recover lost data and erase the unrecognizable internal hard drive
If the internal hard drive is not recognized by your Mac still, then the file system of this internal hard drive could have corrupted. Is there any other way that you can access the data on this unrecognizable internal hard disk?
Of course. You can recover lost data from this unrecognizable internal hard disk with Mac data recovery software like iBoysoft Data Recovery for Mac. Then, you can reformat this internal hard drive so that you can use this drive again.

| Tuxera NTFS could not mount (on OS X) I installed ntfs-3g-2010.5.22-macosx apparently successfully. However, whenever I start the computer (a Mac running OS X 10.6.4), I get the following error message:
'Tuxera NTFS could not mount /dev/disk1s1 at /Volumes/Elements because the following problem occurred:
/Library/Filesystems/fusefs.fs/Support/fusefs.kext failed to load -(libkern/kext) link error; check the system kernel logs for errors or try kextutil(8).
the MacFuse file system is not available(71) _nfts_volume_release(): Inode 9 still have 1 references.'
MacFuse appears to be installed. At least it appears on 'System Preferences'.
What is bad is that my external disk is not even visible after installing ntfs-3g.
I would appreciate any help you could give me.

| Re: Tuxera NTFS could not mount (on OS X) Hi,
If you need to quickly get back your NTFS drives you can just disable NTFS-3G from the NTFS-3G preference pane in System preferences (Apple menu->System preferences->NTFS-3G).
It seems that MacFUSE is broken, or you're trying to use the software with an unsupported configuration such as the newer non-standard fully 64-bit kernel.
If you think that MacFUSE is broken, then try the following procedure:
There is an icon for MacFUSE in System preferences as well (or at least there should be one). Please click it and select 'Remove MacFUSE'. Then reinstall NTFS-3G (which will install MacFUSE with it if you don't deselect MacFUSE when installing). It's possible that this procedure fixes the problem.
Regards,
- Erik
| | Mon Jul 12, 2010 06:36 | Hi. Thanks for the prompt response. It seems that MacFUSE is broken, or you're trying to use the software with an unsupported configuration such as the newer non-standard fully 64-bit kernel. I'm running my iMac in 64-bit mode. I did'nt know this was non-standard, though. Somewhere I have seen that there is a mixed mode so that apps that require 32-bit mode will run 32-bit and the OS as well as apps that can take advantage of the 64-bit processing will run in 64-bit mode. I haven't been able to figure out how to do this. As far as I can see the system gives me a choice between the two modes. It would be a bit unfortunate if you have to have a slower system in order to be able to use NTFS drives. If you think that MacFUSE is broken, then try the following procedure:

Then reinstall NTFS-3G (which will install MacFUSE with it if you don't deselect MacFUSE when installing). It's possible that this procedure fixes the problem. Thanks for the tip. One thing I'm not clear about. I installed MacFUSE separately because it was my impression that you needed to do that with the free NTFS-3G version (as opposed to the comercial Tuxera-NTFS version which installed MacFUSE automatically). So if I install ntfs-3g-2010.5.22-macosx.dmg, this takes care of installing MacFUSE for me? Again, thanks a lot for your help. JM

It would be a bit unfortunate if you have to have a slower system in order to be able to use NTFS drives. This is a common misunderstanding. You do not have to do anything with your computer in order to do 64-bit computing and take advantage of the capabilities of your 64-bit processor. The stock kernel is a hybrid 32/64-bit kernel, fully capable of running 64-bit applications and giving them a 64-bit address space. The fully 64-bit kernel (RELEASE_X86_64) is to be used with systems that have more than 32 GiB of memory (the hybrid kernel cannot address more than 32 GiB), like the Xserve rack servers. For other systems it does not offer any signficant advantage (in general 64-bit code will use more resources because of the larger pointers needed, so it could even be slower) except perhaps in very special cases... We are working on bringing support for the fully 64-bit kernel to our products, but in fact most people shouldn't use it yet (it's mostly for server use at this time). If you think that MacFUSE is broken, then try the following procedure:
There is an icon for MacFUSE in System preferences as well (or at least there should be one). Please click it and select 'Remove MacFUSE'.

So if I install ntfs-3g-2010.5.22-macosx.dmg, this takes care of installing MacFUSE for me? Yes, both NTFS-3G and Tuxera NTFS for Mac come bundled with MacFUSE to make installation as easy as possible. Regards, - Erik
| | Mon Jul 12, 2010 10:26 | Hi Erik and thanks a lot for your prompt and informative reply. This is a common misunderstanding.

OK, as you say the misunderstanding must be pretty common because I've read in many forums and sites (some of them looked like they were run by people who knew what they were talking about) that things run generally faster if you are in the 64-bit mode. I only have 8GB of ram so according to what you say I should be in the default 32-bit mode. But just see this sample of what I was talking about: http://macperformanceguide.com/SnowLeopard-64bit.html If you note, they do claim that 64-bit apps will run faster. I cannot find other links now where they claim that the whole system will in general faster and more efficient. Perhaps they were talking about previous versions of OS X and now things have improved?

JM The main difference would be between 64-bit and 32-bit user space applications. CPU intensive applications are supposed to spend most of their time in user space so any difference in performance between kernels would be hard to notice. The comparison that you linked to confirms that only for very specialized applications there's any noticeable difference at all... but if you want to squeeze out that last 1-2% of a video rendering session you may be helped by the 64-bit kernel. There is a reason that Apple don't turn on the fully 64-bit kernel by default, and it's simply that they don't consider it necessary until the machine can support more than 32 GiB of memory. The hybrid kernel is more compatible with legacy software too, and any difference in performance is marginal, so for the vast majority of people it's the right choice at the moment... but yes we are planning a release that supports the fully 64-bit kernel, though no release date is known yet. Regards, - Erik
| | Mon Jul 12, 2010 20:54 | OK dokey. I'll follow your advice, which sounds pretty sensible. I can always logon in 64-bit mode when I need to do those big rendering jobs.

| | Mon Jul 12, 2010 21:07 | I didn't remember about this but Apple itself contributes to the confusion we were discussing. I went to change the mode back to 32-bits and I see a message that says 'When your computer is restarted, it will run the following version of the Mac OS X kernel:
32-bit (slower, uses less memory, better compatibility)
64-bit (faster, uses more memory, some older kernel extensions will not load)

You have to either edit the NVRAM settings, the boot config file, or press '6' and '4' while the computer is booting to get the fully 64-bit kernel if you are not using any third party 'switching' app.

This message is from an app called SixtyFour Switcher. I just wasn't thinking when I said it was from Apple. JM
| | Mon Jul 12, 2010 22:42 | I am running into the exact same problem on a stock hexacore Mac Pro I just bought.
I don't even know how to switch the kernel between 32 and 64-bit modes, so it appears that Apple is now preinstalling kernels in 64-bit mode. What is the fix?

The latest release candidate of Tuxera NTFS for Mac supports the fully 64-bit kernels. You can grab it from here: http://www.tuxera.com/products/tuxera-ntfs-for-mac/ We would love to have your feedback on how the driver works for you under the 64-bit kernel. If you would prefer not to run a 'release candidate', you can switch to the 32/64-bit hybrid kernel with a simple click of a button using an application called K64Enabler: http://timesoftware.free.fr/k64enabler/ I hope this helps.
