I have a problem with usb drive

I reinstalled xpsp2 and now flashdrive doesnt work when plugged in. Ive tried two different kinds. I reinstalled the chipset drivers and still doesnt work. I have a optiplex 270. Can someone help me

Have a look at the top of the usb forum for the sticky... there is a link to a very useful tool which should help you sort out what's wrong.

Do you get the double bleep when you plug it in? In computer management> disk management, does it show up there without a drive letter?

It makes that one dongle noise. Yes it shows up without a letter

so it is working... tried right clicking on it in disk management and assigning a drive letter?

I did that and its still assigned to the other drives i see the safely remove hardware icon on the tray but thats it no drive is shown?

other drives? Are you saying you have no spare drive letters?

the flash drive isnt showning at all just as a remove hardware under system tray

errrm, in disk management, you said it was showing up... have you downloaded that utility yet?

yeah I assigned a letter for it and I can open it from disk managment,but why doesn't appear with my other drives? maybe I got it configured wrong here is the ini config:

[Settings]

;this activates balloon tips and sets their show duration in milliseconds
ShowBalloonTips=1
BalloonTipTimeout=4000


;here you can let USBDLM remove driveletters of cardreaders as long
;as there is no media present
NoMediaNoLetter=0


;here you can let USBDLM execute the open= line in an autorun.inf file
;on the attached drive
AutoRunEnabled=1

;here you can define a key for the AutoRun feature; Only if the same line
;is found in the autorun.inf file then the open= line is executed
AutoRunKey=



;here you can let USBDLM write a logfile, default is _USBDLM.LOG in the USBDLM folder
WriteLogFile=0
LogFile=
LogLevel=3



;here you can change the balloontip text to your language, default is english
Text_drives=
Text_partitions=
Text_media=
Text_mounted_to=
Text_and=



;-------------------------- the drive letters ---------------------------------

;here you can define new default drive letter for USB drives
[DriveLetters]
Letter1=I
Letter2=J
Letter3=K


;here you can define new default drive letter for USB drives with a
;certain minimum size in megabytes
[DriveLettersSize1]
MinSizeMB=
Letter1=
Letter2=
Letter3=


;here you can define new default drive letters for multislot card readers
[MultiSlotCardReaders]
Letter1=
Letter2=
Letter3=


;these letters are excluded, USBDLM will assign a different letter when
;XP assingns one of these to USB or FireWire drives
[ExcludedLetters]
Letter1=C
Letter2=D
Letter3=G



;many other options are documented in the Help files

So the drive doesn't show up in disk management and doesn't show up in the utility? Have you tried it in another machine?

It shows up in disk managment now. I can open it from there. Why doesnt it show up with the other drive though?

what do you mean... the other drive?

I have 3 hard drives. Normally, when I plugged in a flash drive,it showed up as another drive along with the other hd drives in my computer. Now that I've reinstall xp sp2 I don't see it under my computer. I have to go to disk management to open the flashdrive. How can I fix this?

Assign a drive letter to the flash drive.

I did and it still isnt showing up under my computer

What drive letter did you assign? What other drive letters are assigned to which devices?

c: ntfs drive Ide 37gig
f: fat flash drive 16 gig
d: ntfs ide 80 gig
g ntfs sata 200 gig

Now that this thread has gone a couple days and still no fix I'll offer my probably bad advice:

This site discusses a very similar issue:

http://www.softwaretipsandtricks.com...ve-letter.html

and thus refers to this:

http://www.duplexsecure.com/en/faq

which says to do this:

"A: If your system has some problems with SPTD installation you can do as follows:

If your system is already running then go to step 2 directly. Otherwise start from step 1.

Step 1. Boot in safe mode and press ESC key when you see on bottom line of display: "Press ESC to cancel loading SPTD.sys". This will abort loading of SPTD layer.
Step 2. Find "HKEY_LOCAL_MACHINE\System\CurrentControlSet\ Services\sptd" registry key in REGEDIT and set DWORD Start value to 4 (i.e. disabled).
Step 3. Reboot again in normal mode and check if your issue is solved.

To reenable SPTD restore the DWORD Start value back to '0' and reboot your computer."

NOTE: In my comp I have CurrentControlSet0001, 0002 and 0003 BUT use 0001 if you have that.

Note: In my comp the DWord Start value is set at 0 now - check your BEFORE you change it.

Note: Never hurts to set a restore point BEFORE messing in the registry.

You have a 16GB flash drive?

Certainly is a good week for strangeness! I don't suppose you've used any software to repartition the drive, create hidden partitions or the like? I know Corsair supplies this on their 16 GB drives. I've also seen a couple of reviews that suggest OCZ 16 GB drives may exhibit some strange performance issues (mostly slow transfers).
