Cannot delete an active system partition?

Thanks a lot for the help everyone! I've got everything the way I want it now.

I've already backup everything; that's why I wanted to wipe that drive, heh.

Thanks again.

Glad that you've got everything like you wanted now.

Thanks karlsnooks. That worked perfectly. I had the same problem.

I recently had a similar situation which I could not resolve and called Microsoft. After being moved to a tier 3 tech, the following was attempted - with no promise of success - but it did succeed. They downloaded the Easus Partition Manager as a trial or something, they then chose the drive that wouldn't format as if to change its partitioning. However, they then left it as one partition. In this scenario, Easus gave the option to format the new partition. In this very round-about way, the drive was formatted as a regular drive again.

I write this in case the suggestions above do not work. This might.

Hi there. I've just started having this problem. My secondary drive started reporting a "S.M.A.R.T. Status Bad, Backup and replace" error. Now before I replace the physical drive I wanted to try completely wiping it and reformatting it first to see if that fixes the problem. However when I try to delete the partition from Disk Management is says it cannot because the partition is active.

Note. In my BIOS my secondary drive is listed to boot after my blu-ray/dvd drive. Should I change it so my C drive hosting windows boots after my dvd drive before I try anything else? (Or would my secondary drive likely still be 'active'?)

If so what should I do next? If windows launches should I try the diskpart command below? : -
LIST DISK
SELECT DISK n where n is the number of the disk you want to format.
DETAIL DISK (just to make sure you picked the correct disk)
CLEAN (this will zero out the first and last sectors)
CREATE PARTITION PRIMARY
LIST PARTITION
SELECT PARTITION 1
FORMAT FS=NTFS QUICK (this will format the partition)
ASSIGN (win 7 will assign next available letter; you can change later if you don't like)
EXIT

Or will I still have a problem? I'm just a bit confused on the order of how to fix this? When to use the dispart/when to boot from windows cd? Will I really need to unplug my secondary drive afterwards? etc?

Can I not just partition/format the secondary drive by booting from my windows dvd without using the diskpart commands?

Thanks!

If you clean the data drive it will lose any data, so back it up first.

You'll need to wait until after it is marked Inactive, or in Diskpart bring the Seagate drive Partition 1 into focus and write "Delete Partition Override" to delete it while still a System drive.

You can then run the Repair on C once marked Active without having to unplug the Seagate since it can't interfere.

Remember to set C HD as first to boot in BIOS setup.

Questions?

Hi there. I have this problem and want to be able to format/re-partition my secondary drive without having to remove it from my case. Please can you confirm the steps to do this? Will the following work? : -

Step 1. Make sure my 'C' drive (Windows) drive is the second drive to boot from my BIOs after my dvd drive? (Currently it's my problematic storage drive which is the second drive to boot in the bios which i thought was strange).

Step 2. (Assuming Windows starts) run the following Diskpart cmds: -

First to make the drive inactive: -

List Volume
Select Volume 2 (here I've used the letter 2. You use the correct one for your system)
Inactive

and then to format it: -

LIST DISK
SELECT DISK n where n is the number of the disk you want to format.
DETAIL DISK (just to make sure you picked the correct disk)
CLEAN (this will zero out the first and last sectors)
CREATE PARTITION PRIMARY
LIST PARTITION
SELECT PARTITION 1
FORMAT FS=NTFS QUICK (this will format the partition)
ASSIGN (win 7 will assign next available letter; you can change later if you don't like)
EXIT

When do I run the '"Delete Partition Override"' you mention?

Step 3. - Reboot and see if Windows launches and all is well? If not should I reboot with the windows dvd and go through the Startup Repair steps 3 times? This is the part I'm getting confused about. (And the order of the diskpart cmds above).

Thanks a lot

FYI I managed to get the drive into a non-acitive, non-system state by booting from the Windows disk, making it inactive via diskpart and then running Startup Repair a couple of times.

However I'm going to have to replace the hard disk anyway because I still get the "S.M.A.R.T Status Bad, Backup & Replace error" on startup. That seems like a hardware failure and a topic for another thread.

hey guys I have the same problem on mine which is similar, follow the link to see it E: drive formating problems, system prevents full space wanted
