Re: Weird situation with a 128GB thumb drive

It does have a few more which are not included in Windows by default and require the download of additional Microsoft utilities. The point is that the
help
command only gives brief descriptions, while the website discusses their usage in more detail with examples.

Hi Carlos,
Curious. Does the web site have more of these command lines,
than say, help.txt

You can change the drive letter in Disk Management if you like.

The various commands are documented hundreds of places on the
web. However, one useful resource is here.
http://www.ss64.com/nt/index.html
You can also generate a list of available commands with basic
descriptions on the root of your C drive by typing
help>C:\help.txt
from the command prompt followed by Enter.

Well, I guess you might be a wee bit of a genius but, dont
you go getting a big head.

Yep, I got my 128GB thumb drive back. It now has its default
exfat format with its default alocation size. And, my C drive is
actually still there.

The thumb drive letter did bump up from F to G but, I guess
that doesnt matter.

Ill slightly revise these notes so I will better remember
them.

Carlos, where can I find a list of all of these command lines
that you use?

Many thanks for getting my drive back. And, especially for
sharing your knowledge.

Yes that is correct. Each command has to be followed by Enter
as you described.

OK, starting with the clean command, how many different
commands were there? Do I hit enter after each command?

For example:

1. clean followed by enter
2. create partition primary followed by enter
3. select partition 1 followed by enter
4. format fs=exFAT quick followed by enter
5. assign followed by enter

Carlos,Sorry for my lack of experience . I am however,
learning more almost every day. .

Thanks,

James B

Try repeating the procedure again. I have occasionally
received an error when using the
clean
command for the first time to remove unusual partitioning.

Well, Im starting to wonder if dropping this thumb drive
on a hard tile floor a couple days back may have damaged it.

I got through your directions up to clean.

Then I got an error message so I stopped.

The drive now shows 0 free space. 0 used space. Unknown
drive size etc.

This turned out to be a PSY thumb drive. I have enough
drives around that it isnt important.

Thanks for your help,

James B

Actually upon further consideration, I don't know what you
used to write the ISO image to the flash drive or how the drive
may have been partitioned by that utility, but yes it may in fact
be a similar cause.

No, the problem I was considering is generally associated
with Linux distros which will change the file system on the disk.
You can try the following, but make sure to backup any important
files as this procedure will wipe all existing data from the
drive.

1. Press Windows key+R to open the
"Run"
dialog and type
CMD
followed by Enter.

2. After the command prompt opens type
diskpart

3. When the diskpart utility loads type

list disk

4. Carefully listen to the information displayed.
Review it with the JAWS cursor or equivalent if necessary. You
have to figure out which disk number is assigned to the drive you
want to use. The size column should give you an idea. Warning,
be absolutely sure that you have the correct disk number before
proceeding with the next steps or you could cause yourself
serious problems. If you are not confident that you have the
correct disk number, then I would strongly suggest that you not
proceed.

5. Once you are sure that you have the correct disk
number, just as an example type

select disk 1

1 is just an example and you should replace it with the
disk number which was displayed for the drive in the previous
step.

6. After it displays the message
"Disk 1 is now the selected disk",
type the following commands in order.

clean
create partition primary
select partition 1
format fs=exFAT quick
assign

7. Type
exit
to close the diskpart interface.

8. Finally, type
exit
again to close the command prompt window.

Now look in Computer/Explorer and see if the full 128 GB
capacity is available.

I dont know if this is similar but I tried to use it
for creating a Win10 Creator recovery bootable drive.

I had already tried 2 smaller thumb drives for the same
purpose with no luck. All 3 attempts led to failure around 40%
in to the process.

The other 2 drives were not affected.

Also, have you recently used the drive for booting a
Linux distribution or anything similar?

I doubt it ever had the higher capacity Formatting
probably undid whatever fraudulent configuration was on the drive
to make it report higher numbers.

Hi all,

I recently formatted a cheap generic 128GB thumb
drive. Its original configuration was exfat with 128KB
allocation units and it had a capacity of 128GB.

After a quick format, the capacity changed to 32GB
and fat32.

I did a full format with Windows set to make the disk
exfat and that did work but the size is still only 32GB.

Its no big deal because this was a cheap free thumb
drive. However, I admit to being very curious.

Anyone know why the size of the thumb drive changed
after even a full format?

James B
