I just built a new computer and got it up and running. I have an 80 gig Intel SSD for the boot drive. Everything seems to be working great, but my storage drive (750 GB Caviar Black) isn't showing up in My Computer. I have Windows 7 Home Premium 64 bit.

It shows up in the BIOS and it shows up in Device Manager. It acts like it recognizes the hardware, but Windows doesn't recognize it. The drive has not been formatted. Currently the SSD is drive C and the Blu Ray is drive D. Windows acts like the drive isn't even there.

Any ideas on what is wrong?

Go into drive management where you can partition the drive and format it. It will then show up in My Computer.

Windows will be aware your new HDD exists as a piece of hardware, BUT it still will not show up in My Computer. You need to use Windows Disk Management to do two jobs: Partition and Format that new unit. Click on Start at bottom left and in the menu RIGHT-click on My Computer and choose "Manage" from the mini-menu to open a new window. On its left click to expand "Storage" if necessary and choose "Disk Management". This will open two panes on the right, each of them scrolling to reveal their whole contents. The upper one shows you only the devices Windows already knows how to use. The lower one also shows you the hardware Windows can see, including some devices Windows does not yet understand. Each device is represented by a large horizontal block. On its left end is a smaller label block with things like "DISK_0", a size, and a few other bits of info. To the right will be one or more large sub-blocks representing Partitions already defined. Each of these will have a letter name like your C: drive, its size and File System, and a bit more. If there is some space not yet assigned to a Partition, it will be a block further to the right called "Unallocated Space". The main block representing your optical drive will not have all this stuff because you cannot define a Partition on such a device.

Now, your WD 750 GB disk should be here with no letter name and no info beyond its basic label on the left end. RIGHT-click on its Unallocated Space and, from the menu, choose to Create a Partition on the drive. You'll have a choice of how big it should be and most likely want to use all the drive in one volume. (You can use only part of the space. If you do, when you are finished come back here and find the remainder shown as "Unallocated Space". You can create a second Partition or more in it if you want.) For this first Partition, make it the Primary or Active Partition, and NOT bootable because this drive is for data only - you already have a boot drive. What you do next depends on which Windows you have. If there are no other options to choose in the menus, go ahead with the Partition operation. BUT some systems will have popped up a Wizard when you started to Create the Partition, and you will still have places to set options for the second step, Format. Choose the NTFS File System option. A Quick Format will do the job in 5 to 15 minutes. A Full Format will do a Quick Format, then go though every sector of the drive and test it, marking off any faulty ones (very rare) so they won't be used. Full Format takes many hours!

Now, if you were NOT inside a Wizard and the Partition Creation stage did not include Format options, that stage is done separately. In that case, once the Partition has been created you RIGHT-click again on the new Partition and choose to Format it. Set the options as above and run it.

When you are done, exit out of Disk Management, reboot and your newly prepared hard drive should show up in My Computer as an empty unit ready for use.
