USB Flash Drives creation of "ghost drive" letter


Recommended Posts

Can any help? My laptop has C,D drives,E (CD drive). I add a flash drive

which shows as F. If I add one additional flash drive at the same time this

shows on the Control Panel as Removable Drive G and H (with the correct name

for the USB flash drive). Clicking on Properties for G shows Full and H space

available. I cannot transfer data to Drive H as the messages say the drive is

full. I am therefore unable to use the USB flash drive due to the extra drive

which does not exist. Can anyone tell me how to instruct the XP system to

recognise the USB drive and get rid of "ghost drive" G?

Mine does not do that, it reads F and G so it may be that you need to make

sore your USB drivers are up to date. Put the driver disk in and reload.

> Thanks Ian. My flash drives are USB, without drivers, and are recognised by the system. The problem is the extra drive shown up when it does not exist and this prevents me from adding data to the drive. My flash drive seems to have allocated a spurious number to itself. The struggle continues. Regards

Never heard about an effect like that. You could try an USB drive

cleanup. I've made a simple commandline tool for that:

http://www.uwe-sieber.de/files/drivecleanup.zip

 

It removes from the device tree non present

- storage volumes

- USB disk devices

- USB mass storage devices

 

If you start it while the nasty drive is _not_ attached, then

it's completely removed and will be redetected when it's

attached next time (as all other USB drives which had been

attached earlier and has been not present when DriveCleanup

was executed.

> Dear Uwe,

Thanks for your helpful reply. I ran your cleanup. Out of my 3 flash drives

2 were

recognised with their label name and correctly shown as Drive F, as follows:

Thumb (F)

Thumb2 (F)

the problem flash drive was shown as follows:

Removable Drive (G)

Thumb3 (H)

and not Thumb3 as I would expect. Clicking on Properties then Eject gives

an outlined (in blue) Removable Drive (F) in the case of the twp good drives.

It looks as though the 3rd flash drive has a mixture of two states, a) When

loaded ie Thumb3 (H) and b) drive clicked ready for ejection. This joint

combination is preventing the flash drive from being used.

 

Thanks for your help,Uwe. I shall still continue to try to catch the system

when its back is turned. Even renaming the flash drive did not fool the

system as you can see it still persists in giving totally wrong information

reports. All 3 flash drives were plugged into the same USB port one after the

other.

Regards and best wishes from UK,

Barry

Hi Dorset,

 

Is this a U3 enabled thumbdrive? U3 creates a VD for a CDROM

image that it uses. One drive the CDROM VD can not be

written to, the other drive is the on where you can actually

write to.

 

Note also that if it is a U3 drive it may have come with

software already installed and may be using up some of the

space on the drive. The first U3 enabled thumbdrive I bought

was a Sandisk. It was a 512MB drive and had 260MB of

programs on it.

 

You can go to the U3 site and download a program that will

remove U3 from the thumbdrive and make all space available

to use as one partition.

 

I automatically delete U3 from and thumbdrive I buy since it

will lock up a Mac solid if you plug it in.

 

Ciao . . . C.Joseph

> Thank you. I have decided to take the route of directing the file save to that drive letter which is declared by the system as being open. I have an Integral 2GB flash drive but am not sure whether it has U3, it certainly it had a password facility which I deleted. On analysing the flash drive it said that it was 12 bit and should be 32 bit FAT. As I am at the stone age part of this branch of rocket science I shall leave things as they stand. At least my other drives or OK. Grateful for your interest and help. Regards
