I'm just trying to ensure I get rid of all the GPT partitioning completely. You can't use disk management to do this - you must use diskpart (or third party tool but there is no point really).Thanks for that mate. If you are formatting after without 'quick' option it doesn't matter but. There is also 'Clean all' which zeros the disk. You can't use disk management to do this - you must use diskpart (or third party tool but there is no point really). If you did a 'quick' format as mbr knows nothing about the second backup gpt structure it could in theory be retrieved.

If you omitted the 'quick' the second backup partition table would also be overwritten and could not be retrieved. If you just 'clean', 'convert mbr' and then format with 'quick' the first partition table will be will be overwritten certainly. GPT has a second (backup) partition table at the end of the disk and I'm not sure if clean deletes that. I have GPT formatting on one of the drives and need that back to MBR so that's why I'm asking about using Diskpart for the whole procedure'Clean' destroys the partition table. I don't think Delete Volume fully does that. Can anybody enlighten me a bit on what that means?Īs far as I'm aware the Disk Management Console doesn't contain the equivalent of the Clean command in Diskpart. Obviously it looks like it has Yes/No choice. Ive looked under detail volume for the flash drives and there's a No Default Drive Letter option but I'm not sure really what that means. I want it to be dynamically using E: but not fixed on it. Will the assign command set the drive letter as dynamic? Or does Assign set the drive letter to the next available letter and Fix it on whatever drive letter that is? In my case C: is system drive and D: is DVDRW drive.

How exactly does that work? I want my flash drives to dynamically assign drive letters each time they're inserted-I don't want a fixed drive letter. There is another command-Assign that I know can be added after Active. Are they the same for factory resetting a USB flash drive? I have some instructions I use when using Diskpart to create a bootable USB flash drive to install Windows 10. What is the correct way to do it with Diskpart? I know you can format the drive but I want to set everything up.partitions etc back to the way they were. Ive a couple of USB flash drives that I'd like to wipe clean and factory set them back to the way they were when I bought them.
