I am using Windows XP SP3.

My external hard drive isn't showing up in windows explorer. It does show up in the disk manager and it says healthy.

I have tried changing the drive letter and that didn't work. I have also tried plugging it into a different usb port.

It has never done this before. What is going on?

Post the data reflected in Disk Management for this drive, please.

Both from the upper and lower levels of the Disk Management screen.

Sorry about the delay.

I'm not sure if this is you wanted me to do, but I'm including a screen capture of the Disk Manangement screen.

I've also have tried plugging in my MP3 player and that doesn't show up either.

Yes, I can hear it power on. I just tried a new USB cable and it still doesn't show up.

Could it be something as simple as a service turned off?

I'd run the appropriate hard drive diagnostic.

Up until now, the only times that I can recollect where drives showed in Disk Management bu5 not in My Computer...

a. Malware.

b. Damaged file system (NTFS/FAT)...or failing drive.

c. Same drive letter assigned to 2 drives. I don't even think that can happen today.

What is the appropriate diagnostic? I have ran CHKDSK on it twice.

Chdsk only verifies the file system to check the actual hard drive there are test to make sure you dont have a defect in your drive

you can look in here http://www.bleepingcomputer.com/forums/topic28744.html or http://www.tacktech.com/display.cfm?ttid=287

Find the appropriate manufacturer (WD,Samsug, ect and download the application for that test.

I have a WD and I needed to check if my drive have a defect I would look for WD diagnostic test in that link I provide

When I plug in mp3 playing into my computer, via USB, it also cannot be found in windows explorer. I've tried several different cables, in every one of my USB slots, with the external hard drive and mp3 player, and still nothing.

I don't think the problem is with the hard drive. What else could be preventing stuff that I plug into my computer from showing up in windows explorer?

EDIT:

Ok, this is weird. Now when I change the drive letter of the external hard drive, it'll show up in windows explorer if I have windows explorer open, but when I close windows explorer and then re-open it, the external hard drive is no longer there.

Try this:

Start/Run...type devmgmt.msc and hit Enter. Scroll down to Universal Serieal Bus Controllers...double-click.

On each item which reflects "controller" in the description...rightj-click and then Uninstall.

Do this for every item under USB Controllers...which haa "controller" in the description, do not bother with any other devices/items listed under USB Controllers.

Reboot the system. see if things work properly now.

That's a very interesting observation.

I have a suspicion (and it is only a suspicion) that malware may be at play here.
  • I am thinking "rootkit".
  • I suggest posting a new topic (or having this topic moved) to the Am I infected? What do I do? forum and requesting help to check the system for the presence of malware, and in particular a rootkit.

Hello, let's do three scans and see if we can spot something.

Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware Posted Image and save it to your desktop.
  • Important!! When you save the mbam-setup file, rename it to something random (such as 123abc.exe) before beginning the download.
Malwarebytes may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.

  • Make sure you are connected to the Internet and double-click on the renamed file to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • Malwarebytes will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button and continue.
  • If you cannot update Malwarebytes or use the Internet to download any files to the infected computer, manually update the database by following the instructions in FAQ Section A: 4. Issues.
  • Under the Scanner tab, make sure the "Perform Quick Scan" option is selected.
  • Click on the Scan button.
  • When finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box, then click the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked and then click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows the database version and your operating system.
  • Exit Malwarebytes when done.
Note: If Malwarebytes encounters a file that is difficult to remove, you will be asked to reboot your computer so it can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally will prevent Malwarebytes from removing all the malware.

-- Some types of malware will target Malwarebytes and other security tools to keep them from running properly. If that's the case, go to Start > All Programs > Malwarebytes Anti-Malware folder > Tools > click on Malwarebytes Chameleon and follow the onscreen instructions. The Chameleon folder can be accessed by opening the program folder for Malwarebytes Anti-Malware (normally C:\Program Files\Malwarebytes' Anti-Malware or C:\Program Files (x86)\Malwarebytes' Anti-Malware).


>>>>
Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

    Posted Image
  • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.
-- If you encounter any problems, try running GMER in safe mode.
-- If GMER crashes or keeps resulting in a BSODs, uncheck Devices on the right side before scanning
.



>>>>
Please download aswMBR ( 511KB ) to your desktop.
  • Double click the aswMBR.exe icon to run it
  • Click the Scan button to start the scan
  • On completion of the scan, click the save log button, save it to your desktop and post it in your next reply.
