USB Flash Drives Not Showing in "My Computer"

by library_tech / September 22, 2009 11:32 PM PDT

System: Dell Pentium 4 - Windows XP Pro SP3 - on a domain

Problem: I work for a public library. We have several (not all of them) of our Public Access Computers (PAC) that when a patron plugs their flash drive into the USB ports, the computer recognizes it, assigns it a drive letter that does not conflict with any other drive letters and still does not show the drive in "My Computer".

Solutions I have tried that did not work:

1. Drive letter conflict due to network drive mappings.
Result: I have eliminated all partitions and network drives. The computers simply have a C: drive and the dvd/cd drive in D:. PROBLEM PERSISTS.

2. Removing Daemon Tools, including SPTD.
Result: The drivers and program were not found on the computers. I installed them simply to be able to uninstall them. After uninstall, PROBLEM PERSISTS!

Any help on this would be much appreciated.

You claim a drive letter is assigned but
by R. Proffitt Forum moderator / September 22, 2009 11:47 PM PDT

Does not show in Explorer (which is "My Computer". That's proper and supported. Research TWEAKUI HIDE DRIVE LETTERS and you'll see where Explorer does not have to show the drive.

Tried it...

I checked the registry and modified the entry to have explorer show all drives. Still unable to see the flash drives in "My Computer" or Explorer.

Thanks though.

This is more than one entry.

Remember you told me that the drive letter is assigned. But not showing in My Computer. There are POLICY settings at play too but a clean install of XP does not do that.

Be sure to enable AIN too. (google XP AIN if you forget it.)

That's no bug.

Hiding drives from My Computer is a well known area. I haven't read a reply or screen shot that shows TWEAKUI with the drives all good.

Nothing really busted here. Just keep asking why they locked out the drive letters from Explorer.

Since you're in a setup that may have various sorts of flash drives of all types and sizes, thus flash drives themselves can be a PITA, because they're junk. I exclude any OS acknowledgments, etc. to proceed. If used, is there a USB type firewall, check that? Our local library doesn't even provide USB access as the possibility of malware attacks. Then, there is the issue of rear and frt. panel USB ports, over time the frt. port(s) get hosed or lack the "umphf" to power USB devices. Next, there is the MAC and PC side effects, they may work or may not after use from either system to the other. Last, did you manually assign a drive letter to the flash drive within HD/computer(i forget) management? As you can see many things may effect the USB port, check these out.

I did try manually assigning a drive letter, and that didn't change anything.

Thanks for the advice though.

So, I have continued to try different things from reg edits to services to mapping, still no success.

However, I am able to open from and save to flash drives. When I open a program like "Paint" or "Word", I can open the flash drive and open a file off of the flash drive, I also can save to the flash drive. However, it still does not show in "My Computer". I have uploaded a screen shot that shows disk managment, my computer, paint, and the save as window from paint if you would care to see it. here is the url.

Go into your bios sand find where usb settings are and make sure that you set them usb 2.0 and check if everything ells in the usb settings are OK .Also try to enable P&P in the bios.

In reply to: Checked.

that if the machine uses usb 1.0 and the usb device is 2.0 it may do that and even the other way round.

I think the only way your going to solve this is get a new one

Just so you know.

This is not a BIOS, USB version or hardware issue. It's just a policy setting that you haven't found yet. The issue is well known so all that you need to do is find the setting.

find the setting...

Any idea what setting?

We've covered using TWEAKUI so what's next is to ask the person who installed the OS what policy they used on Explorer.

Some get confused over My Computer and Explorer. Explorer is what's running that show.

Always fun to re-discover or ask "now what did they do?"

There are many ways to lock down Explorer. Look at all of them.
