I'm using Mountain Lion 10.8.2.
Need to use my 2TB NTFS partition.
Until last Max OS, Tuxera or Paragon used help me detect my 2tb ntfs HDD.

After installing Mountain Lion, my harddisk is not detecting, it says
"The disc you had inserted is not readable by this computer"

please help

After installing ML, you may need to reinstall Paragon, which does work with ML.

after installing ML, i had installed my existing paragon setup, which didn't help me detecting my 2tb hdd

further, i downloaded the latest version from their website (which they claim to work for Mountain lion), but still it didn't help.

There's something faulty with either your ML or NTFS setup. Paragon's "claim," as you call it, is correct. Their NTFS driver for OS X Mountain Lion works well.

I had a similar problem.
Try repairing the hard drive in recovery mode.

Do you have the latest version of Tuxera or Paragon? I've been using Tuxera on my machines these last several years and haven't had a problem with it not working as I install new version of OSX (currently at 10.8.2).

nope, no limit of file size.

but if u must know the difference between NTFS and ExFAT.

Exfat can not be used in LINUX and NTFS can not be used in OSX.


just format ur 2TB to Exfat....and avoid those 3rd party apps all together that are sometimes unreliable

Yes, there are file size limits to both, but they are extremely high.

That's not true. OS X can natively read NTFS and writing can be enabled via several methods.

That's not true, either. Paragon is extremely reliable.

Format A Hard Drive Using Disk Utility (which is in your /Applications/Utilities folder)

Choose the appropriate format:

HFS+ (Hierarchical File System, a.k.a. Mac OS Extended (Journaled) Don't use case-sensitive)

NTFS (Windows NT File System)
  • Read/Write NTFS from native Windows.
  • Read only NTFS from native Mac OS X
    [*]To Read/Write/Format NTFS from Mac OS X, here are some alternatives:
    • For Mac OS X 10.4 or later (32 or 64-bit), install Paragon ($19.95) (Best Choice for Lion and Mountain Lion)
    • For Mac OS X 10.5 and later, including Lion, FUSE for OS X
    • For 32-bit Mac OS X, install NTFS-3G for Mac OS X (free) (does not work in 64-bit mode)
    • Some have reported problems using Tuxera (approx $36), which is an enhanced version of NTFS-3G with faster performance.
    • Native NTFS support can be enabled in Snow Leopard and later versions, but is not advisable, due to instability.
  • AirPort Extreme (802.11n) and Time Capsule do not support NTFS
  • Maximum file size: 16 TB
  • Maximum volume size: 256TB
  • You can use this format if you routinely share a drive with multiple Windows systems.

exFAT (FAT64)
  • Supported in Mac OS X only in 10.6.5 or later.
  • Not all Windows versions support exFAT. See disadvantages.
  • exFAT (Extended File Allocation Table)
  • AirPort Extreme (802.11n) and Time Capsule do not support exFAT
  • Maximum file size: 16 EiB
  • Maximum volume size: 64 ZiB
  • You can use this format if it is supported by all computers with which you intend to share the drive. See "disadvantages" for details.

FAT32 (File Allocation Table)
  • Read/Write FAT32 from both native Windows and native Mac OS X.
    [*]Maximum file size: 4GB.
  • Maximum volume size: 2TB
  • You can use this format if you share the drive between Mac OS X and Windows computers and have no files larger than 4GB.

Recovery System

OS X Lion or OS X Mountain Lion includes a built in set of utilities in the Recovery System. Restart your Mac and hold down the Command key and the R key (Command-R), and keep holding them until the Apple icon appears, indicating that your Mac is starting up. After the Recovery System is finished starting up, you should see a desktop with a OS X menu bar and a "Mac OS X Utilities" application window. Note: If you see a login window or your own desktop and icons, it is possible that you didn't hold Command-R early enough. Restart and try again.

Go into utilities, to repair your hard drive.

The format depends on how the OP intends to use it, which is why providing such details is appropriate. If you read those details, you wouldn't be posting misinformation.
