USM16GLX 16GB MicroVault Click Excellence - capacity issue

[supersub70]

Hi - I've been given a Sony USB stick which is marked and sold as a 16GB drive however when formatted it only shows as 4GB avilable. I have formatted the drive in both FAT32 and NTFS and both return the same total capacity (4GB) - Is it possible a 16GB chasis has been mixed up with a 4GB stick at the factory? Or is there something else I'm missing here?

Regards

Cancel that! My USB had been partitioned for use with a Juniper Device (somehow).

for info I ran a cmd.exe then as follows;

1. Diskpart

2. Select disk 1 (assuming the USB is assigned disk 1 - check in Windows Disk management first!!!)

3 .Clean

4. Create Partition Primary

5. Select Partition 1

6. Active

7. format fs=fat32

8. assign

9. exit

NOTE: I actaully only followed to point 3 then went to the Windows Disk Management console to do the rest.

Happy Days

Hi,

I'm having a similar problem, although my 16gb shows it has the 16gb free.

when I try to transfer a file of 8.5gb it says the file is too large, same with 4.5gb. Anything below 4gb does fit however.

So is there a file size transfer limit?  Or is the software that comes with it meant to 'simulate' a larger drive, and it's actually only a 4gb drive?

thanks

Hi littlejon87,

The 4GB transfer limit would suggest that the Flash Drive is formatted as Fat32 – 4GB being the maximum file size that can be stored on a FAT32 volume. Fomating the drive as NTFS should solve the problem.

Thanks for the info!  Re-formatted it and works a charm - thanks

When I reformatted it, it asked for allocation unit size?  Do I need to bother changing any of this? I left it at 4kb

Hi littlejon8,

Please to hear that this solved your problem

4kb is the default and max cluster size for the drive capacity you are using. If it is working leave well alone.
