Disk Utility does not display my drives (Mac)


 If the options in Disk Utility are dimmed, you are not logged in as administrator. If you know the name and password for an administrator; click the lock icon (Tiger and prior) and enter the information. If the MicroNet device volumes are still not appearing, turn off the MicroNet device, check all cable connections, wait 10 seconds and re-power on the MicroNet device.You may need to reboot your Macintosh for the drives to be seen.


How do I format my disk drive for use on MacOS X?



Most of Fantom Drive's disks come preformatted at the factory with the NTFS file system, the native file system for Windows. Linux and Mac OSX hosts require a third-party driver such as NTFS-3G to achieve full read/write capability with NTFS volumes. If you intend to use this drive exclusively on MacOSX it is advised to reformat your disk with the HFS ("Mac Extended") file system.
Formatting a hard drive erases all data contained on it. Please be sure to create a copy of the files you wish to keep to another location before reformatting.
Formatting the drive in Mac OS X
1. Launch the “Disk Utility” application located in Applications/Utilities.
2. Highlight your new drive and select the “Partition” tab
3. Select the new partition map type.
4. For each partition in the volume scheme, select the desired file system format and volume name (optional)
Although it is possible to format using the DOS file system, we do not recommend this as an artificial capacity limit may be imposed on the drive and performance will be unpredictable.
5. Click the “Options” button. Select “GUID Partition Map” in the dialog box and click “OK”.
6. Click “Apply.” Your Fantom Drives GForce3 Mega is ready to use!

I can't safely remove my Fantom Drives disk. When I try, I get the message “The disk "my disk” is in use and could not be ejected. Try quitting applications and try again." What can I do?


The operating system is informing you that there are still files open by your operating system, and the OS is preventing the unmounting of the volume to avoid data loss. This can be either because there are still files that are meant to be written but are still cached, or that the operating system is using the drive for background processes such as indexing or temporary space. To identify the process that is accessing your disk, you may use Mac OS X's built in utility to identify open files, lsof (click for more information.) Alternatively, you can use third party applications such as What's Keeping Me from HAMSoft  to identify which files are open on your drive.

I have a disk I use on my PC. When I connect it to my mac, it's showing up "read only".


Disks formatted as NTFS will be available for Macintosh computers in read only mode. NTFS has limited compatibility with Mac OS natively (requires 10.4 and newer, read only.) Full read/write compabitility can be achieved using NTFS-3G (Free) or it more featured commercial version, Tuxera. You can find information on both here: http://www.tuxera.com

Full interoperability for both Windows and Mac systems have two strategies:

1. Format the disk HFS+ (Mac native)


HFS Plus or HFS+ is a file system developed by Apple Inc. to replace their Hierarchical File System (HFS) as the primary file system used in Macintosh computers. HFS Plus is an improved version of HFS, supporting much larger files (block addresses are 32-bit length instead of 16-bit) and using Unicode (instead of Mac OS Roman or any of several other character sets) for naming the items (files, folders.)
HFS+ volumes can be accessed by Windows machines using third party software such as MacDrive from MediaFour, www.mediafour.com.  
2. Format the disk NTFS (Windows native)
NTFS is the best and most current file system for Windows hosts; NTFS has several improvements over FAT and HPFS (High Performance File System) such as improved support for metadata and the use of advanced data structures to improve performance, reliability, and disk space utilization, plus additional extensions such as security access control lists (ACL) and file system journaling.
NTFS has limited compatibility with Mac OS natively (requires 10.4 and newer, read only.) Full read/write compabitility can be achieved using NTFS-3G (Free) or it more featured commercial version, Tuxera. You can find information on both here: http://www.tuxera.com/
Please be aware that these solutions are not endorsed by Microsoft(R), Apple(R), or Micronet/Fantom Drives.

I'm trying to copy files to/from FAT32 volumes or network shares, and it keeps failing.


FAT32, HFS+, and other file system formats allow different standards of filename length or use of special characters. Rename the offending file(s) and try the operation again.


My computer does not recognize the Drive.


 First, check to make sure that all of your connections are secure, and that the power switch is in the "ON" position. Then check if your MicroNet device is listed in the Apple System Profiler. If the problem persists, verify that the port used is functioning.


My Macintosh computer is unable to format my 1.0tb (or larger) external hard disk.


to format large (1TB and greater) partitions under MacOS you will need to repartition the drive with a Mac partition scheme. In Disk Utility, go to the Partitions tab, where it says, "current" select "1 partition" and then click "options" at the bottom of the page.  In the window that pops up please select either APM (Power PCs) or GUID (Intel Macs).  Click Apply and then Partition, the format should complete within a matter of minutes.


Since upgrading/installing Mac OS X 10.7.x, I can no longer access my NAS by AFP, and can't use Time Machine.


Apple has removed access to prior versions of Apple File Services in MacOS X 10.7. As a workaround, you may re-enable access by following the procedures described in this Apple knowledgebase article:

When formatting my MegaDisk MDEXXXX external eSATA/USB hard disk on my Mac OS 10.5.x or 10.4.x computer I receive the error message "Resource is busy" or "Input / Output error" and cannot complete the format.


MacOSX has difficulty working with drives of larger than 1.0tb in size. There is a firmware update that when installed on the drive will allow you to use the drive normally. Fortunately, upgrading the firmware on the drive does not require a great deal of technical ability, just a special utility.

MacOS 10.5.x http://www.siliconimage.com/docs/57xxSteelVineManager_V5.1.24.leopard.pkg.zip

MacOS 10.4.x http://www.siliconimage.com/docs/57xxSteelVineManager_V5.1.24.tiger.pkg.zip

The link above is the utility in question. Run the file inside the zip, and install the program. You'll then find it in your applications folder in a folder called "57xxSteelvineManager" The application is run by double-clicking the "SteelVine" icon inside this folder.


The above file is the firmware, download it to your desktop and unzip it.

If you ran the SteelVine application while the drive is connected (this is necessary in order to update the firmware) you'll see some colorful buttons across the top and some information about the drive to the right. In order to upgrade the firmware you must click the second from the last button on the top (when you mouse over it you will see "Specify Firmware"), click this button.

The software will ask for a password, the password is "admin" without the quotes. In the window that pops up click "browse" and then locate the file that you unzipped onto your desktop. Finally, you must click the "Install Firmware" button on the bottom right.

While the firmware installing DO NOT disconnect the drive or turn off your Mac. This process takes a few minutes and you will get a pop up window telling you that the process was completed successfully when it is done. You must restart your computer and the drive at this time.

Once that is done you can format the drive. In Disk Utility, please go to the Partitions tab, where it says, "current" select "1 partition" and then click "options" at the bottom of the page. In the window that pops up please select either APM (Power PCs) or GUID (Intel Macs). Click Apply and then Partition.


When I leave my computer idle and return a short while later my drive does not work properly.


The most likely cause of this is that your computer is going into sleep mode. The immediate solution is to shut down your computer and turn off the drive, and then restart your computer. Once your computer is completely booted up, turn on the drive and it should be available again. To prevent this problem from recurring, open the “Power Settings/Energy Saver” and disable sleep mode for the drive(s).
