USB Stick 16GB many partitions (GPT)

[bartzokn]

Hey guys
So after few weeks ago i installed hackintosh in a laptop and the guide i followed suggested to convert the bootable usb to gpt efi from mbr.After the installation i tried to format the usb stick and i ended with this situation.Many partitions of 1 mb and allocated space of 14GB.I have tried a lot of things fix it such as known softwares and from the cmd but everything failed.I just want to fix it so i can have it for installing OS's.

P.S
I have attached a photo from Storage Manager of Windows 7 if it helps

Delete the all the partitions and then reinitialize it.

I tried that many times.I delete them and when i refresh they are still there.And i am not getting error about deletion

I strongly suggest you make or make sure you have a recent backup of your pc because the there is a chance that you can mess up the following and erase the wrong drive. You've been warned.

Search for CMD but do not run it. Instead Right click it and select Run as Admin

type in DISKPART and hit enter

type in LIST DISK and hit enter.
- this will list out all the disks found in your system. Determine which disk is your Flash Drive.

type in SELECT DISK # (replace # with the number for your flash drive) and hit enter

type in CLEAN and hit enter (this erases the drive)

type in CREATE PRIMARY PARTITION and hit enter

type in FORMAT FS=FAT32 and hit enter

type in EXIT and hit enter.


You can close the CMD window now. Your flash drive should now be formatted and usable if it is still in working condition.

I tried that and i get the following.I must say it does not let me also to delete any partition (you can see them in the photo in my first post).

No usable free extent could be found. It may be that there is insufficient
free space to create a partition at the specified size and offset. Specify
different size and offset values or don't specify either to create the
maximum sized partition. It may be that the disk is partitioned using the MBR di
sk
partitioning format and the disk contains either 4 primary partitions, (no
more partitions may be created), or 3 primary partitions and one extended
partition, (only logical drives may be created).

What was the result of the CLEAN command?

 

[bartzokn]

Clean command was successfull.After that i also tried to start disk management with the hope to initialize the usb but i couldnt

I'm at a loss to resolve this.

I was hoping you received a message that the flash drive was write protected, which is often fixable with a registry edit.

It wouldn't hurt to try a 'clean all' instead of just a clean, this will take a little longer to complete as it will try to zero every cell on the flash drive.

 

[bartzokn]

Tried clean all and it was succesfull in about 1 sec but still the same.I think the flash is corrupted.Thanks anyway for all the answers

 

[popatim]

Yeah, that was my belief when Clean did not work. Sorry.
