Problems Formatting HDD

Hey guys, I have two HDD in my computer, a WD 1TB Black with Windows 7 Professional on it and an older WD 320GB. The 320 was used as a backup for vista when I had it installed and now that I have 7 installed I would like to format that drive and use it as a backup for 7. When I try to format the 320 windows says it can't format the drive. Why? There is nothing that I need anymore on this drive and would really like to prepare it for backing up my 1TB. FYI.....I did a clean install of 7 from the upgrade version of 7......if this makes any diference. I did have the 320 plugged in while the clean install was taking place. I thought Iread something about this a few months ago but I can't seem to find what I maybe read. Thanks in advance.

If you really don't need anything on the drive start "Computer Management" then click on "Disk Management" highlight the 320GB Drive and delete the partition. Once that is done re-create the partition and format it. Note: You will need to do this with Administrator Rights.

Perhaps the new install is using the old drive as the boot drive. Attaching a picture of your Disk Management window might help us see what is happening.

It's likely the 320gb contains the boot critical files for Win7 if it won't delete in Disk Mgmt.

Post back a screenshot of your full Disk Management drive map, using the Snipping Tool in Start Menu, attaching file using paper clip in Reply box. We can advise you the exact steps to fix this then.

Normally the procedure is to mark the drive inactive, mark Win7 HD active, then run Startup Repair from the booted Win7 DVD up to 3 separate times with reboots to write the MBR to the Win7 partition.

However we need to see the screenshot to advise you with certainty.

Here's the Disk Managment.

Now I remember what I read about that but I still need to fix it.

How do I mark the 320 as inactive and the 1TB with Windows 7 on it as active?

First set Win7 HD as first HD to boot in BIOS, or swap HD cables, making sure Win7 HD is first HD to boot in BIOS boot order, after DVD drive.

Boot into Win7 DVD, select Repair my Computer on second screen, click through to Recovery Tools list, open a Command line and type:

DISKPART
LIST DISK
SELECT DISK # (# for Backup HD)
LIST PARTITION
SELECT PARTITION # (# for Backup partition)
INACTIVE
SELECT DISK # (for Win7 HD)
LIST PARTITION
SELECT PARTITION # (# for Win7 partition)
ACTIVE
EXIT

Now return to DVD Recovery Tools list, run Startup Repair up to 3 separate times with reboot to write the MBR to Win7 partition.

I list disk 0 as inactive and disk one as active? Why is disk 0 the backup? Wouldn't the drive with 7 on it be listed as 0?

It has to do with what port you plugged HD's on mobo.

The screenshot shows Backup partition as System Active which means the MBR was derailed to there during Win7 install, as installer looks for first active partition to place MBR. It now needs to be marked inactive using diskpart or free bootable Partition Wizard CD, so that MBR can be recovered to Win7 partition where it belongs.

If you want to make Backup DISK1 so that it can't derail the boot again by accidentally becoming marked active, then swap the cables to HD's. Make sure Win7 is HD set to boot first in BIOS boot order, after DVD.

using DISKPART commands given earlier or Partition Wizard booted CD, Determine which HD is which by size and partitioning, then select backup partition to mark inactive using exact DISKPART commands given or rightclick in PW to Modify>Set Inactive.

As Win7 partition is already marked active, as long as it is set first HD to boot in BIOS boot order (after DVD), the MBR should be recovered by booting Win7 DVD Repair console to run Startup Repair up to 3 separate times with reboot, to write the MBR to Win7 partition.
