Just as we have been exchanging this mail, clean all command finished, so all is well now. Thanks for your help anyway. Just for the others who will possibly do this, the clean all process was 5 hours long for me.

Great news.

Yeah, "Clean all" take a long time to finish, and should really only be used if you're giving or selling the drive to someone else.

Very quickly---seconds. Similar to a quick format.

Clean all would take hours.

Thanks for a very interesting discussion and especially Brink for all his input. I have read evry post on this topic and haven't seen my problem discussed. Somehow my 160Gb Western Digital HDD has been reduced to 137Gb of unallocated space by using Clean All with my Windows 7 installation disk. The rest of the space has disappeared as shown by Windows 7 Disk Management, DiskPart(Installation Disk), or Seagate Disk Wizard, with the drive connected to an IDE port or a USB interface. The drive, my Bios, and the USB interface are 48bit LBA capable. Any suggestions?

Hello Woody, and welcome to Seven Forums.

That would be about right. For more information on why your HDD or SSD may not be the size as advertised, see:

HDD's - the Advertized size vs the Actual size

Please go ahead and post a screenshot showing the drive in Disk Management to see what it shows.

Thanks again Brink for your quick response. As requested, here are the screenshots of pertinent programs, DiskPart, Windows DiskManagement, and Seagate DiskWizard.

I probably confused the issue by stating my drive was limited to 137 GB. The drive is a Western Digital 1600BB-22RDA0, advertised as a 160 Gb drive. This shoud be interpreted as 160 x 10exp9. If you do the math and convert to an exponent of 2exp30 what you will find is that all these programs should tell me the drive is 147 GB. I'm wondering if I did something in DiskPart that wiped out something on the drive used by it for property information. Perhaps someone out there has had a similiar experience.

Woody,

I don't see any other partition that could be using the space for your K (Disk 6) drive.

I agree that by the math a 160GB hard drive should show as 147GB, and not 128GB. Possibly a mislabeled drive. If it's still new, I would return it for one that's not shorted.
