I was trying to upgrade to a bigger hd and couldn't lock my new hd after cloning the original. Is that drive gone for good now?

Not all drives can be locked...

The drive wasn't on the compatablity list so I thought I would try it. It's a Maxtor 5T040H4
Since I can't lock it, is the drive useless now?

No you can still format it and use it in your computer or what ever

My PC won't recognize the drive anymore...i'm assuming because it's unlocked.
How can I lock it or what can I do to get my PC to recognize the drive?

I think it is unlocked....I unlocked it and when using xboxhdm got the error that it wasn't lockable. Now my PC won't recognize the drive.

You can use an unlockable drive in an xbox (as long as you're not soft modding) but you will not be able to boot M$ bios or use live.

I'm softmodding

My PC recognizes the drive but it doesn't show up in My Computer...I'm confused

Just right click and format it if you plan on using it in your pc.

This is pretty simple. Don't fret.

An unformatted drive won't show up in My Computer. You just need to format it.

You can use Partition Magic, but you don't need to. You do need Admin access on your PC.

Go into the Administrator Tools. Go into Computer Management. Click on Storage and then Disk Management.

You should see your unformatted HDD. Format as you please.

Thanks for the tip finding the hd in computer management. I can see the drive but how do I format? I can't find that option anywhere.
Thanks

You might need to fdisk it depending on what partitions exist.. I'm not sure if there is a way to do it in windows without hunting for certain software.. I don't do stuff like that in Windows, if I could eliminate Windows from this planet I would..

You dont need fdisk. Right click on the drive and click on new partition. Make it the maximum size. Once it creates it, right click on it again and click on format. That should do it.
