Hi all,

I have a 80GB Freecom USB HD, I had it partitioned into 2 (which I did using Leopard disk utility).

I wanted to erase all data and revert to 1 partition, so I started up disk utility and selected erase from the options but it just froze.

Now my HD is not recognized by my Alu Mac, but still shows up in disk utility and I can not do anything with it at all.

The HD shows up in device manager on my PC but thats it.

Please tell me it,s not broke.

Wayne.
 
So it shows up in disk utility right?

Use disk utility to repartition and format.

It must not be showing up on the desktop because there are no correctly formatted and recognisable partitions.

Tried that, but disk utility freezes, I then have to force quit and the whole OS also freezes.

I am still new to Mac and this is getting to me now. Everything has been fine up till now.
 
Can you post a screen shot of what you see in the disk management window?

Its formatting now but as NTFS. There was no option for FAT 32.

Never knew about that manage option.

Will let you know how it goes.

Many many thanks.

NTFS is not writeable from OS X. Still, if you can at least get it formatted with something readable, you can then give it another go in OS X Disk Utility. Delete all partitions, recreate and format with Mac OS.

Thanks again, whats the correct order? Do I need to erase first.

What I'd do....

Let the NTFS formatting complete on Windows.
Make sure the disk shows up in Windows.
Move drive to Mac.
With Disk Utility kill of the NTFS partition and make a new one.
That *should* be it.

I had to go out earlier, just got back in. The HD showed up in XP and works fine under windows, I tried to reformat it using disk utility, but still no joy. Came up with input/output error.

Back to square one. I will try it again with XP.
 
Not working with XP again so reformatting, looks like a problem with Leopard disk utility. Once XP has done it stuff I will try again with Leopard.

Now I come to think of it, I am certain that I formatted the disk using Tiger and partitioned it with Leopard.
