Hi,

I have a couple of HDDs that I want to wipe.  There were part of a RAID 1 operating system drive.  I plan to attached them via a USB adapter (so they don't get recognized as RAID / Boot Drives).  

What is the best utility to erase all partitions on these drives, to effectively restore them to "as-new" state?

Here is a couple of solutions:

Any recommendations for these or others?

The quickest is hook them up as the primary drive on a Pc, start the install process, delete the partition, create a new one, let windows start installing into that partition and shut the system off.

That partition will be blown and all files that were on that drive will be toast.

You don't have to do anything.  Just install the new O/S.  It will write 1s and 0s where it needs to and ignore the rest.

I recommend DBAN.
That's what I use for hdd's that I donate, and never had problems.

Can be a bit slow sometimes, but after a few passes you're sure that the data cannot be recovered by mere mortals...

HTH,

All good answers.  Thank you.

But, I want these drives and backup drives (not for future Win OS Install).
Just really want to wipe the partitions quickly.

DBAN looks like the closest fit to what I am after.  
Although a quicker partition delete would be handy in this respect.

If you just delete the partitions then data can still be recovered from them.  The only way to completely erase the data so it's unrecoverable is to run a wipe program like DBAN, as has been mentioned already.  I typically run the DoD Short wipe, which is a 3 pass process.  On large drives this can take a whole day.

If you just want to wipe the partitions, open Disk Management, right click on a partition and choose delete. It's that simple.

deleting the partition(s) leaves all data intact to be recovered
if you don't want that, you can use Dban, or any other utility - but it is not what you ask here "Just really want to wipe the partitions quickly" - it will take HOURS
most disk diagnostics also have a utility, like write zero to the drive, which is sufficient to render data unrecoverable  for most uses

Just put linux on a USB stick and type in dd if=/dev/zero of=/dev/sda count=1 and this will blow away the partition in a fraction of a second. But as I wrote, you don't have to do anything if you want to repartition it. Just  delete the partition with whatever O/S you are running.

There is no such thing as an "as new" partition.

I see.

I had trouble deleting the partition at one stage.  But I think because I plugged it in to the server it came from.  And I think the RAID controller saw it and the BIOS saw the boot sector and tried to boot it.  So it wouldn't let me delete the partition that way.

It all got a bit easier once I put the HDD into a USB enclosure and connected it after booting.  Yes it was easy to just delete the partition then.

But thanks for all the tips
