USB Flash Drive

[Guest]

Hi

I have recently purchased a Bytestor 512Mb USB Storage Device.

I use a Sony Vaio laptop.

When I plug in the device, the drivers install but it assigns either A: or B: drive letter to the device. My laptop doesn't have a floppy, so it assigns A: is my USB floppy is not present, or B: if it is.

The problem is that the device then only shows as having available space of 1.44Mb when it's as above. The device does not show in Computer Management, so I cannot change the drive letter (why would it show in My Computer but not Computer Management?)

The device correctly shows as a Mass Storage Device in the 'Safely Remove Hardware' balloon, but always the USB Floppy Device is installed also, and it's this driver my laptop seems to insist on using. Under Disk Drives in Device Manager it shows a USB Mass Storage Device, but also lists it under Floppy Drives.

How can I disable it from being installed as a floppy drive and recognised correctly as a 512Mb device? I've tried the drive on 3 other laptops and it works on only one, with the same problem as above on the other two!

Any advice greatly appreciated as I'm stumped.

right click "my computer"
click on "manage"
click on "Disk Management" in right window pane
in bottom left window pane
locate the thumb drive and reassign a dafferent letter to it.

Unfortunately, as I wrote, the drive does not appear in
Disk Management - so I can't assign a new drive letter!

Can anyone shed any light on this?

Click Start-Run-Type REGEDIT and click OK. Now expand to the following:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\USB\Vid_Xxxx

Check under each of the Vid_Xxxx and see if any of them list your Pen
Drive as the DeviceDesc or LocationInformation.

If you manage to find the one your Pen Drive and/or Floppy drive is
listed under, right click on the folder it is listed under (the one
starting with Vid_Xxxx) and delete it. Now reboot and plug it back in
and see if it fixes the problem.

Hi

I have recently purchased a Bytestor 512Mb USB Storage

Device.

I use a Sony Vaio laptop.

When I plug in the device, the drivers install but it

assigns either A: or B: drive letter to the device. My
laptop doesn't have a floppy, so it assigns A: is my USB
floppy is not present, or B: if it is.

The problem is that the device then only shows as

having available space of 1.44Mb when it's as above. The
device does not show in Computer Management, so I cannot
change the drive letter (why would it show in My
Computer but not Computer Management?)

The device correctly shows as a Mass Storage Device in

the 'Safely Remove Hardware' balloon, but always the USB
Floppy Device is installed also, and it's this driver my
laptop seems to insist on using. Under Disk Drives in
Device Manager it shows a USB Mass Storage Device, but
also lists it under Floppy Drives.

How can I disable it from being installed as a floppy

drive and recognised correctly as a 512Mb device? I've

hello alex,
i see this problem was some time ago but perhaps I can help from my own
experiences with a bytestor device. It is normal for the bytestor to
assign a floppy drive to A or B but in order to access the remaining
storage it looks to assign an additional letter. I had a problem on my
work pc where I could see the floppy drive(assigned as B ) but the
usbdiskpro drive showing the remaining storage never appeared. I
noticed that all my devices up to F were assigned and F was
assigned(mapped) to a network drive. I disconnected the network drive
to free up F: and immediately the USBDISKPRO drive appeared as F:
So to permanently solve the problem I remapped the network drive as G.
Not sure if the problem is the presence of the network drive or whether
it only searches up to F: but anyway this fixed it for me.
I hope that this situation will somehow match your set-up. If not
perhaps this information can be useful to someone else searching for a
solution in this forum.
