Why can't I clone a Hard Drive in Disk Utility
I have asked this question a few times in different posts on here, but no one seems to be able to answer my question.
My tale of woe is this.
I bought a new Western Digital MyBook 1tb Hard Drive to replace the 250gig Lacie Hard Drive that I have been using for Time Machine. I want to clone all the old Time machine info from the old drive to the new one.
I was advised I could do this in Disk Utility. And to do it format Mac OS Journalled. I ran erase as Mac OS Journalled and it finished, but then when I went to restore it the new partition is greyed out, so that I can't select it to use as the destination. In fact no matter how I format the drive, it is always greyed out. The only way I can select it is to reformat the drive as FAT32. So then I try to clone the old drive but it errors out because apparently I can't copy a file over 4gigs... considering the drive I want to copt is almost 200gigs of info this is no good to me.
Whenever I try to do anything I just get errors like this...
I get this error when I try to partition it into a Mac OC Jounalled

As you can imagine this is driving me mental. Does anyone have any suggestions at all?
I know the new drive is fine because it mounts when it is FAT32 and I can copy files to and from it.
Thanks in advance.

I do clone my HDD with super duper. It works flawlessly.
If you just want to clone your HDD get that app. Its only $29 and it will pay for itself when you get a new HDD or restore form a cloned drive.
If it still won't restore, try using superduper or carbon copy cloner to copy everything over.
Maybe try changing your partition scheme in the partition tab of Disk Utility, which appears if you select the drive itself. Click on options and switch from Master boot Record to GUID partition table. Choose the format as Mac OS Extended (Journaled). Then hit the partition button.
If it still won't restore, try using superduper or carbon copy cloner to copy everything over.
Okay, I have finally completed the task that I set about trying to complete a week ago.
I reformatted the drive s instructed above as one partition of GUID Mac OS Journalled format.
I then wanted to clone my Time Machine back up hard drive to the new hard drive in Disk Utility. When I tried using the restore function, it would copy all the back-up's that had been created using "Backup", but would error out on the first app when copying the time machine backups.
Confused, I then tried Carbon Copy Cloner and it too errored out, but on the third app in the apps folder of the first time machine back up file.
Before giving up I tried to clone the hard drive using Super Duper!
11 hours later I now have a perfectly working cloned hard drive. I redirected my time machines to the new hard drive and it backed up to the correct folder as if nothing had changed. So all is good now and I just wanted to thank everyone for their advice.
Thanks.
