It should work OK.
If you want to exchange data between a PC and a MAC then then hard disk will need to be formatted on a PC in FAT32 file system. if you only want to use this hard disk on a MAC then you can format the hard disk with your MAC in HPFS file system.

SOURCE: external hard drive is dead

Hello

Okay , so there are some steps to figure out what is wrong with your external.

Firstly , if your computer makes a sound when you plug in your external , go to Start-Control Panel-Administrative Tools-Computer Management-Disk Management , and see if your external drive is listed here with your local drives. If it is listed , right click on the drive and change the drive letter to make it appear in "my computer".

If your drive does not make a connection sound when connecting to your computer and also does not show up , please follow the next step.

Remove the hard drive from the casing if possible and install it in your computer case or another external case.If the drive works , the problem is with the casing and you can ignore the drive.

Now , if the problem is with the casing , there are still 3 possibilities.

  1. The USB cable between the drive and the computer may be damaged.
  2. The circuit board which connects your drive to the interface of the external may be blown.
  3. The power supply (if applicable) may have a blown transformer.
The latter is the easiest to diagnose , does your external light up at all when you plug in the power? If not , then this is probably your problem. On the bottom of the adapter is a label which you will be able to use to have a new adapter made at your local electronics shop and this will cost about $30 max. They will also be able to test the adapter with a clamp meter to see if this is really the problem and this should be free.

The second component you want to test is the USB cable. If you have a printer , swop out the cables and see if your printer functions normally. Most externals use the same connector so you should be able to test it in this manner. If the cable works go on to the last step. If the cable is defective , replace it with a new one which you can find for about $10 at most electronics and chain stores.

The last component to test is the circuit board. This is a bit of a grey zone as you probably won't be able to spot the blown component unless it failed really badly. With the casing already opened , locate the external's circuit board and check to see if you have any blackened components or fluids leaking from some components. If all the other components of the external worked perfectly , then this is the faulty part. It is not really economical to replace the circuit as most of the time it is out of production by the time you need to replace it and it still costs a lot even if it is available so if your drive is working perfectly when connected via sata or IDE on your computer , the best is to buy a new casing and place your old drive in the new casing.

A casing costs about $50 and you could get it at most tech shops and big chain stores like Best Buy.

I hope this solves your problem and please reply if you need more help.

Kind Regards
Andrea

Tip

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.

• 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.
-----------------------------------------------------------------------------------------------

Can i transfer information to a mac


If the external hard drive has been formatted on a PC in NTFS file format then the MAC cannot read data off this hard drive.
The FIX..
Connect the USB external hard drive to a Windows computer and copy your data off this hard drive to the computer.
Then format the external hard drive in FAT32 file format. (the MAC can read and write to data to and from a Windows PC)
Now copy the your data from the computer back onto the external hard drive.
Now you can connect the external hard drive to the MAC and download your data to the MAC.

My mac is reading my transcend storejet 25 mobile 320gb, but i cant copy files from my mac unto it


Hello Kinoshia,

It seems that Transcend external hard drive have different file system. This is because the Mac machine is not able to transfer the files on to external hard drive. Please format the Transcend external hard drive from Mac machine and then hard drive is ready to accept the data from Mac machine. The drive either has to be formatted for Mac( HFS & HFS+) or FAT32 partitions. If you want to use
Transcend external hard drive for both Windows and Macs than format the drive to be FAT32.

Cannot copy files to Iomega 500 GB external hard drive.


It depends on how you formatted the the drive.
If it was formatted FAT it will work on both Mac and PC.
If you formatted to HFS+ (the native mac format) then it will only work on a mac.

You have not yet formatted the drive to work with you MAC. You will need to use your MAC's Disk Utility to format the drive in order to write to the drive, but be aware that formatting will erase everything already on the external drive, so back up anything on the drive you want to keep first.
