Windows 7: Disk formatting

Disk formatting

I had installed win 7 on a HDD that was then being reported as having read write probelms. I pulled the drive and installed another drive and installed win 7 on the new drive. Now I would like to reformat the old bad drive which is now drive d on my system. But windows 7 will not allow me to format it. My guess is because it has the OS on it. I have tried to delete the OS on Drive D but am told by the system that it can only be done by a "Trusted Installer". Does anyone have a suggestion on how to either format the drive or to erase the OS from that drive?? I have tried formatting from the DOS prompt and it asks for the volume ID and will not accept what I enter.

One way would be to put the win7 dvd in and do the same as you did with first install. But when you get to choose which partition to install windows on, delete the d: partition and format it, then EXIT the installer and reboot into your installed windows.

Providing that your current (working) installation has no dependencies on D:, could you not do it by taking full ownership/control of the drive and then reformatting it through diskpart?

You could try that but depending on the size of the drive and types of system files on it, it might be hard.

How so?? If the the administrator has full permissions/control of the drive, running the 'clean' command in diskpart would just wipe the drive wouldn't it. I've done the same for my own 300GB drive and had no issues.
For example
Code:
  • diskpart
  • list disk
  • select disk #
  • clean
  • create partition primary
  • select partition 1
  • active
  • format fs=ntfs
  • assign
  • exit
  • exit
