Windows 7: Win7 not recognising new 3rd HDD

Win7 not recognising new 3rd HDD

The BIOS sees it. System Info for Windows sees it, but shows no drive letter. Device Mangler lists all 3 drives, but is not much help because Properties shows no Volume or capacity for any of the HDDs.

Can I assume this drive is an unformatted blank? How do I format it if Win is not seeing it?

Any help really appreciated.

Before we can offer the best advice we need to see a screenshot of your fully-expanded disk management layout please.

By fully-expanded, we need to see not only the partitions but a full view of their respective titles.

If the drive hasn't been partitioned Windows won't see it.

No... what is needed is a screenshot from running DISKMGMT.MSC.

Then maximize it to full-screen and spread the columns so that the test in each cell of the upper-half is fully readable.

Thanks again guys. I think I am seeing the answer but I will ask you to confirm. The disk is a blank.

See attached, but also when I ran diskmgmt.msc I was told that I had to initialise the new drive before it could be used. That seems pretty definitive.

EDIT: Uploaded a better shot.

Initialising a drive is the same as giving the drive a partition.

Every new drive needs to be intialised and formatted before you can use it.

Just right-click the drive in question, choose the option to create a new volume (partition), then give the new partition a quick format and a drive letter.

Windows should then see it, but you may need to reboot first.

OK. Thanks.

I was worried that maybe Win 7 was not seeing the drive, although it had data on it. I realise that an empt6y drive will not be seen by Windows. I was worried that somehow Windows would not see a drive that _did_ have data on it. I think that has happened.....:)

As I said, when I started to use the diskmgmt.msc utility, I started to believe that the disc was empty.

So. Thanks for the help guys, again.

I'm still not quite sure. The diskmgmt.msc app is still under windows. Can I be sure that the drive is empty, based on what I am seeing? I do not want to unnecessarily lose data. As I say I would just like confirmation.
