Question about Iomega 1TB Desktop USB 2.0 Hard Drive

How do I reformat an external Hard Drive that came with NTFS to work with MAC OS X version 10.4.11? I've gone to Disk Utility but then I don't know what to do. The instructions say to use the Erase command, but that doesn't seem to be an option.

Disk UtilityTo completely erase a Macintosh hard drive that runs OS X 10.3.x or above—not just individual files on the drive—you can use the Disk Utility that is built into the Macintosh operating system.

How to Use Disk Utility to Erase a Macintosh Hard Drive (OS X 10.3.x or 10.4.x)

  1. You must reboot your computer using the OS X system CD that came with your Macintosh. To do so, follow these steps:
  • Insert the CD into the CD drive.
  • Hold down the C key during the startup process.
  1. Select your preferred language. You will then see the Welcome to the Mac OS X Installer window.
  2. From the Installer Menu Bar, click Open Disk Utility. You will then see the Disk Utility window.
  3. In the left pane of the Disk Utility window, click the drive you want to erase.
  4. In the right pane of the Disk Utility window, click the Erase tab.
  5. From the Volume Format drop-down menu, select Mac OS Extended (Journaled).
  6. In the Name field, highlight the existing text and type the name the hard drive is to be called after it's formatted.
  7. NOTE: If you ever plan to connect another computer running OS 9 to this hard drive, you'll want to install the Mac OS 9 disk driver, so that this disk will be visible from an OS 9-booted computer. If you don't know if you will do this in the future, it's best to install these drivers.
  8. The following are the available security options:
  • Don't Erase Data—This option only rewrites the headers on the disk. Files can be recovered by forensics, disk utilities, and other advanced recovery software.
  • Zero Out Data—There are forensics utilities that, albeit expensive and time consuming, can retrieve zeroed-out data.
  • 7-Pass Erase—This is considered sufficient by government standards to erase data from a disk. It writes random data over the disk seven times. It may take several hours or more to complete this process.
  • 35-Pass Erase—This makes it absolutely impossible to regain any data off the drive. This option takes an extremely long time, possibly more than one day.
  1. Click the radio button in front of 7-Pass Erase (recommended by UD).
  2. Click OK.
  3. Click Erase.
  4. Confirm you want to erase. The program will unmount the volume, partition the drive, and rename the volume to the name you typed in step #7 above.

Cant delete or add new files to my NexStar.3, I have it connected to a MacBook Pro


If you can SEE the drive on your desktop but cannot modify it's contents there is a good chance it is formatted as NTFS which is a Microsoft Windows format. Mac's can only read/copy information from these drives and not write/delete/modify them. You have 2 choices, you can erase the drive and reformat it as Mac OS Extended (Journaled) (Mac/Linux only) or you can format it as MS-DOS (FAT32) which is truly cross platform but slower to read and write to from a Mac. To reformat the drive you use Apple's "Disk Utility" program in your utility folder.

Formatting an external hard drive with Mac OS X's Disk Utility


Formatting your new external hard drive is not as difficult as you may think. In fact, you don't even have to be a computer techie or uber-Mac geek to perform this procedure successfully.

The tool you would use, to format your drive within your Mac OS X system, is the built-in utility application called Disk Utility.

Disk Utility is Apple Inc.'s defacto utility application, for performing disk related tasks within the Mac OS X volume.

47fc804.png

From creating new images, to burning CDs and DVDs to formatting hard drives, Disk Utility performs well enough to keep not only your Mac OS X volume on your hard drive error free, but keep your hard drive healthy and error-free as well.

I could go on in detail, admirably describing more features of this versatile Mac OS X tool, but the purpose of this FixYa tip, is to show you how to easily format your external hard drive. So that is where I will take you now.
-----------------------------------------------------------------------------------------------
There are generally two formats in Disk Utility that you can use to effectively format your hard drive.

Mac OS Extended (Journaled) - if you want a Mac readable hard drive only

MS-DOS (FAT 32) - If you want your external hard drive to be read by both Mac and PC.

-----------------------------------------------------------------------------------------------
--STEPS FOR FORMATTING YOUR HARD DRIVE WITH DISK UTILITY--
-----------------------------------------------------------------------------------------------
• First, make sure your external hard drive is connected securely to your Mac and is turned on.

•Next, from your desktop, click anywhere on a blank space on your desktop. Now you should see Finder listed near the Apple menu icon.

• From the Finder menu, click on Go, then Utilities from the
drop-down menu. This will take you to your Utilities* folder.

(*You can also get to the Disk Utility application via Applications > Utilities folder)

• Now, locate and launch the Disk Utility application.

When Disk Utility opens you will see a left side window, which will show
all connected hard drives and optical drives. It is here that you
should see your external hard drive listed in that window.

• When you locate it, simply select it and then select Partition
from the tabs on the right hand side.

a11d5a9.png

• Change the Volume Scheme from Current to 1 Partition

• Make sure to provide a name for your new external hard drive.

• Select Mac OS Extended (Journaled) from the Format
drop down menu, for a bootable Mac only external hard drive.

• Or select MS-DOS from the Format drop down menu, for a bootable Mac & PC external hard drive.

From there, click the Options button, located toward the bottom of
your window.


This will open a partition scheme selection window as seen in this screen shot:

04286c5.png


• Select GUID Partition Table for bootability on a Intel processor based
Mac.

• Or select the Apple Partition Map for bootability on a PowerPC based Mac.

• Click the OK button.

Finally, click the Partition button and allow Disk Utility to format your new external hard drive.

When this process is complete, you now have a newly formatted, ready to use hard drive.

Believe it or not, this process can be completed faster than you think.
Using this method with Disk Utility, I was able to format my new 1TB Iomega USB external in less than 20 minutes.
-----------------------------------------------------------------------------------------------
Final Note:
I used the external hard drive as the focus for showing you how to format and prepare your hard drive for use on your Mac, but this feature can also work with internal hard drives as well.
-----------------------------------------------------------------------------------------------
For more information about some of the disk repairing features of Disk Utility, here is a great support link for this nifty and quite effective Apple utility for the Mac OS X platforms:

Windows is unable to read the usb


When you formatted the drive for the Mac, you probably used the HFS format. Windows can only read NTFS or FAT formatted drives. You will need to reformat your external drive again. If you use a FAT32 format, all computers will be able to read the drive (Windows, UNIX and Mac - anyway). Note: the FAT32 option does limit the number of files in each directory and the maximum file size.

First back up any files that you have put on the external drive to another disc (your computer's hard disc, for example).
If you are using the M2 external disc for Time Machine backups, you should partition the drive into two sections. Format one to the FAT32 and the other to HFS.

The Disc Utility in OSX can repartition the drive and reformat it. However, sometimes it doesn't correctly format the new partitions. You may need to do some extra step, see http://www.cs.ubc.ca/~pcarbo/macnexstar.html for one set of reformatting steps. In Windows, there is a similar utitily in the Disk Management Control Panel. (Start > Control Panel > System and Security > Administrative Tools > Create and format hard disk partitions (Windows 7)) You can only format the disc to FAT or NTFS with the Windows utility.

Some third-party software is available for changing the partitions on a hard drive formatted for Windows use without losing the data on the disc. I do not know if similar programs exist for OSX.

Some versions of Unix have gparted which will also repartion and reformat a hard disc but can't keep the original data on the drive. (I've used the Windows and Unix partition managers, including Paragon Partition Manager which let me keep my original Windows data on the drive.)

I hope this helps.

How do I format my external hard drive with my macbook


Disclaimer: the following process will reformat your external drive, and also erase all the data on it. There is no possible way to reformat the drive while retaining the data, as reformatting requires erasing.
Press cmd+space to open up spotlight (or just click the magnifying glass in the upper right corner) Type "disk utility" and the first result should be an app called "Disk Utility" and has the icon of a hard drive with a stethoscope. Hit enter.
Connect the hard drive to your computer, and you should see it pop up in the box on the left side of the window. You should actually see two things: a disk icon with the size of the drive and maybe the brand and, below it and slightly indented, a disk icon with the hard drive's name next to it. That's the one you want to click on. In the top middle of the window, you should see an "Erase" tab. Click on it. Pick "Mac OS Extended"* in the Format drop down Rename it if you want to in the Name text box
Click the "Erase" button
It will then reformat the drive to be compatible with Macs.
*Use Mac OS Extended if you plan on using it to store files. If you want to install Mac OS X on it, choose "Mac OS Extended (Journaled)". If you want to be able to access the files from a PC running Windows, you should choose "MS_DOS (FAT)", though I would not recommend doing that if you don't have to, because it is rather slow.

My 2TB g3 station doesnt wanna work on my mac os x 10.4.11, it says it cannot be modified.


You problem is most likely because the hard disk is formatted using NTFS which can be read on MAC OS but does not allow writing data on it. Solution is to backup your data somewhere and give it a clean format.
Click on the spotlight icon (the magnifying glass) in the upper right corner of your screen, and typing "disk utility."

Once in disk utility, select your external drive in the list on the left of the Disk Utility window, and click "erase". Select FAT32 as your file format, name the volume, and click the "erase" option.

REMEMBER TO BACKUP YOUR DATA as everything will be wiped out during a format!

I have macintosh so when i put the external hard drive it works with no problems but when i want to get sth as a backup from windows ,,the pc cant see the hard drive,except if i formated the hard drive,how...


Your Mac can read Windows hard drives, but it can't write to them. There is a free software to allow the Mac to read Windows formatted drives, but it's a bit technical. You have to install Mac-FUSE (search Google) and NTFS-3g (go to www.macupdate.com and search for NTFS-3g).

There is commercial software that will allow Windows to see Mac OS Extended (HFS+) formatted hard drives, including MacDrive. I believe it's about $50. If you are using Windows on your Mac via Apple's BootCamp feature and you have Mac OS X 10.6 "Snow Leopard", make sure you install the drivers from the Snow Leopard disc that will allow Windows to read Mac formatted disks.

You can also format your external drive as FAT 32 from your Mac (use Disk Utility in /Applications/Utilities). But FAT is ancient. That's MS-DOS's filesystem. It's not great. But if you want to do it, use your Mac (yes, your Mac because it can format larger drives as FAT than Windows can):

**WARNING***WARNING*** this will ERASE all data on the hard drive. Back up first!***WARNING
1. Click the magnifying glass in the upper right corner of your Mac's screen.
2. Type: Disk Utility
3. Click the Disk Utility Application that comes up (or press Return if you're using Mac OS X 10.5 or 10.6).
4. Click the icon of your external hard drive.
5. Click the Erase tab.
6. Change the format to FAT 32 and Give the drive a one word name, no more than 8 letters.
7 Click the Erase button. ***WARNING*** This will erase your drive!
8. Now the drive can be read by Windows or Mac OS X.

Whew! Lots of info. I hope this helped. Please let us know if it helped. Let us know if it didn't, too. We'll do our best to help. If this helped you, please rate me.

Good luck!

I cannot copy files FROM my Western Digital 500GB


Hi,

Check the file system of your hard drive. If your PC is recognizing it, check if its a FAT or NTFS. If it is NTFS then you have to reformat it using your Mac and choose FAT. Mac OS recognizes NTFS as a read only drive. If you plan using it with your PC and MAC you should format it using your mac and choose MS-DOS in disc Utility. You cannot format the drive using your PC Computer with a FAT file system because of the capacity. Only Mac can format it with a FAT file system.

The Mac OS can't natively write to NTFS (it can write to FAT32 however). But if you install MacFuse followed by NTFS 3-G on OS X then you'll be able to write to your NTFS drive.

How do I reformat my 500gb external hard drive for my mac?


Well, you can plug it into your mac, and then open the applications folder on your mac(by opening the Macintosh HD icon first) and opening the utilities folder and selecting Disk Utility. Through disk utility, you can reformat any drive to Mac OS(preferably journaled.) so that you can use it with Time Machine, and the MAC OS.
