Partition USB Pen Drive

Urthboundmisfit said:

The Windows Master Boot Record (MBR) partition structure supports a total of only 4 partitions per HDD / SSD, they can be either 4 Primary partitions or 3 Primary partitions and a single extended partition. By replacing one of the four primary partitions with an extended partition, you can then make an additional 24 logical partitions within the extended one.

Partition / Extended : Logical Drives

This is irrelevant in the context.

@JDobbsy, Try to define a partition and format the space (e.g. in Fat32) and assign a drive letter. I would use Partition Wizard to do that. But it may not work with Partition Wizard or Disk Management.

whs seems to be on the right track. I'm interested in what Diskpart thinks about the partition.

If you've already formatted it, I can try it here (different devices, different results)

If you haven't formatted... would you do me a favor?

Open an elevated Command Prompt and type

Diskpart
lis dis
sel dis 1
lis par
lis vol
sel vol 4
det dis
det par
det vol
exit
exit

Make sure you SELect the correct DISk - I went by the Disk Mgmt. screen shot above.
The LISt PARtition shows you the partitions on the drive
The LISt VOLume shows you all volumes
If I counted correctly volume four (4) is the 19.29 GB
The following gives more.... detail about the objects.
DETail DISk
DETail PARtition
DETail VOLume

thanks.

What are the details about the flash drive - Make model....

I will test in the morning when back at work, thank you for the help/suggestions.

Not so clued up with all this so here are the screenshots as the drive is right now.

Hope this helps:
The pen drive is a 32GB USB 3.0 DataTraveler G4

Odd. I'll check mine in a bit on my W8 system.

I may have done something in the wrong order or formatted it wrong at some point so maybe i have missed something very simple.

Lol, Jimbo do you ever bother reading threads starting at post #1?

Thanks JDobbsy,

Did you follow this post by whs, or did my long post bury that suggestion?

It's difficult to guess at the partitions from this side of the screen. You followed what I posted, but seeing the data now, I should have asked you to select partition 0 on the flash drive.

If you get the chance, try displaying the detail for that partition - there isn't any volume on the partition, so don't worry about the vol command

Using the information from your previous screen shot
The key information you're looking to grab is for the 19GB Logical (extended) partition.
in an elevated command type:

Diskpart
lis dis
sel dis 2
lis par
sel par 0
lis par

the selected object (partition) has an asterisk on the left of the object name
i.e. * partition 0

det par
exit
exit

Thanks,

Bill

Your Disk Management pictures look very similar to mine. On both sticks (a 16GB and a 128GB) I defined a storage partition after I installed Mint Mate on the stick. For the definition of those partitions I use Partition Wizard. They work perfectly well under Mint but there is no way to assign a drive letter for Windows.






If you want to know more about the process I use, read this tutorial. Chapter 2 describes the creation of the storage partitions.
