SOURCE: a service section installation INF is invalid.

Just to be clear, no special drives are necessary. MSC mode will work out of the box with just about any OS. MTP mode will work as long as you have WMP 10 or 11 installedFirstly, lets explain MSC mode and MTP mode a bit.

MSC stands for Mass Storage Class. When your player is in this mode, the computer will see it the same way it would see a flash drive, as a removable disk. It will assign it the first available drive letter, as well as one for the memory card (if applicable). This is probably the more popular of the 2 modes, and is a more "open source" type of standard. Most comptuers detect the player in this mode without a problem.

MTP stands for Media Transfer Protocol. It is a Microsoft standard and is Microsofts solution to connecting digital players and cameras to a window based platform. MTP mode must be used in order to transfer ANY Digital Rights Managment (DRM) protected content. Services like Rhapsody and Napster will only function in this MTP mode.

SanDisk has provided both of these modes at the users options on MOST of the entire Sansa Line mp3 players. The c200, and The View, do not have these 2 options in every version of firmware. Instead those players use an "Auto Detect" function that is suppose to Automaticly use MTP mode. If MTP mode does not work for any reason, it should default to MSC mode.




Switching between MSC and MTP modes


  • Turn the Sansa on, if it is not already
  • Navigate to the main menu of the player; this is the same menu that gives us options such as Play, Record, Info, etc...
  • Navigate to "Settings" on the main menu of the player.
  • After navigating to "Settings", we should see an option that states "USB" or "USB MODE"
  • From here we can select MSC or MTP modes (could vary based on player model)
  • Highlight the desired mode and select it, at this point it will roll back to the 'Settings' menu
  • Connect the player to the computer and verify it is connecting in the desired mode.
It should be noted, when a device is in MSC mode, it will appear as a "Removable disk". When connected in MTP mode, it will show up as an "Audio Device"
You can also try to reinstall Windows Media Player 10 or 11. Next W*ndows has a update to fix if all else fails try this. http://www.microsoft.com/downloads/details.aspx?FamilyId=A2E73160-E862-4F19-BB26-C0CAFE798955&displaylang=en

Cant install u-disk to pc


Do you have internet access with this computer?

If so, you should be able to google the brand and model number and find a driver to download.

I would give that a try.
There is no need to reinstall windows to fix this. The driver or inf file is damaged. Visit another computer with win xp, search for files named usbstor. Copy files usbstor.inf and usbstor.pnf into windows/inf folder and usbstor.sys into windows/system32/drivers. Now just search for new driver and that's it, usb storage will be recognized.

Computer cant detect the printer


Hello,
Go to C:/windows/inf and look for files called oemXX.inf oemXX.pnf.

Open the .inf files one by one and look for the EPSON label in them and when you find one just delete the .inf and .pnf file equivalent. There might be more than one EPSON files in the inf library.

Then unplug the printer, restart the computer, and the add wizard should pop again when you replug the printer.

Hope this helps.

Windows xp will not load


Ah, the "Blue Screen Of Death".

Solution as follows:

To resolve this problem, start your computer in Safe mode, remove the display adapter, rename the .inf files that are associated with the display adapter drivers, restart your computer in Normal mode, and then update your display adapter drivers. The following steps describe this procedure in more detail:
  1. Start Windows in Safe mode. To do so:
    1. Restart the computer, and then press F8 while the computer starts.
    2. On the Windows Advanced Options Menu that appears, use the ARROW keys to select Safe Mode, and then press ENTER.
    3. Use the ARROW keys to select the operating system to start, and then press ENTER to start Windows XP in Safe mode.
  2. In the message that states that Windows is running in Safe mode, click Yes.
  3. Click Start, click Run, type msinfo32 in the Open box, and then click OK.
  4. Under System Summary, expand Components, and then click Display.
  5. In the right pane, note the information that corresponds to the INF File item, for example, Nv4.inf, Oem0.inf, or Atim128.inf.
  6. Quit the System Information utility.
  7. Click Start, right-click My Computer, and then click Properties.
  8. Click the Hardware tab, and then click Device Manager.
  9. Expand Display adapters, right-click the display adapter, and then click Uninstall.
  10. Click OK.
  11. Click Start, click Run, type cmd, and then click OK.
  12. In the Command Prompt window, type the following commands, and then press ENTER after each line: ren %systemroot%\inf\INF file name from Step 5.inf *inf.old
    ren %systemroot%\inf\INF file name from Step 5.pnf *pnf.old
  13. Close all open windows, and then restart the computer in the typical manner.
  14. Log on to Windows by using an account that has administrative privileges, and then wait for Windows to detect new hardware.
  15. When the Found New Hardware Wizard starts, click Cancel.

    If you receive a stop error after you remove the updated display drivers, restart the computer and use the Last Known Good Configuration option. To do this, restart the computer, and then press the F8 key while the computer starts. On the Windows Advanced Options Menu that appears, use the ARROW keys to select Last Known Good Configuration, and then press ENTER.

    If you receive a "System Has Recovered from a Serious Error" message when Windows starts, restart the computer again. This error message does not recur.
  16. Obtain and install the latest drivers for your display adapter.For information about how to contact your computer manufacturer, visit the following Microsoft Web site:

Unable to access my 4 GB Transcend pen drive with Windows Vista Home Premium Edition. Able to access it with Windows XP successfully but always prompting "Unable t find driver" when tried with Vista


Here are the 3 possible solutions to this problem,

SOLUTION 1 :- 
Make sure the you have the Service Pack 1 installed for you vista computer.
You can find it out by opening the run command and type "winver" (without quotes) there. If it's not showing SP1 please update Windows Vista to Service Pack 1 which includes the update to fix this problem as this was the problem when vista was launched but fixed with SP1.

If updating vista does not resolve the issue try the solution provided below:

SOLUTION 2 :- 

Manually locate the driver within the Vista operating system. 

Microsoft Windows Vista may not find any driver for the device that is plugged in the USB port because the usbstor.inf (for MSC device) or wpdmtp.inf (for MTP enabled devices) is not present inside the C:\Windows\INF folder.  

To resolve this issue, you must copy the driver files to the C:\Windows\INF folder. 

Browse to the following folder:

1. C:\Windows\System32\DriverStore\FileRepository. 
2. Look for the folder that starts with usbstor.inf_. 
3. Copy all the files inside this folder to C:\Windows\INF. 
4. Disconnect and reconnect the device. 



If the problem still persists, try this Solution: 

SOLUTION 3 :-
Clear hidden devices and make changes to the Registry

First backup your registry by  following these steps,
1. Click Start 
2. Type regedit on the start search field, then press Enter. 
3. Click File then select Export. 
4. Under Export Range select All. 
5. Type in the desired name to be saved. 
  
STEP 2 - Remove Hidden Devices 
1. Click Start.. 
2. Type cmd on the start search field , then press Enter. 
2. Type set DEVMGR_SHOW_DETAILS=1 and press Enter. 
3. Type set DEVMGR_SHOW_NONPRESENT_DEVICES=1 and press Enter. 
4. Type start devmgmt.msc and press Enter. 
5. Device Manager window will appear  
5. Click View, then select Show hidden devices. 
6. Click + to expand Imaging devices, Unknown devices, and USB devices. 
7. Verify if there are any devices and unknown devices (including grayed out devices). Uninstall. 

STEP 3 - Remove all oem*.inf files 
1. Click Start. 
2. Type cmd on the start search field and press Enter. 
3. In the command line, type in the following commands and press Enter after each command: 
  cd \windows\inf 
  ren infcache.1 *.old 
  ren oem*.inf *.old 
  del C:\windows\setupapi.log 
  exit 

STEP 4 - Remove entries under HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\USB 

Remember,if you have a USB keyboard or mouse, do not remove the VID entry for these devices, otherwise, Windows may not restart correctly. 

1. Click Start 
2. Type regedit on the start search field, then press Enter. 
3. Click on the "+" symbol beside HKEY_LOCAL_MACHINE 
4. Navigate to \System\CurrentControlSet\Enum\USB. 
5. Highlight and delete all the VID_xxxx entries. 


Please note that if you have a USB keyboard or mouse, do not remove the VID entry for these devices, otherwise, Windows may not restart correctly. 
  

After this turn off your PC completely then with the PC turned off, plug the USB flash drive to a USB port and then turn on the PC. 
Now, a New Hardware Detected balloon will appear and the USB drivers will load automatically.

Please let me know if the problem persists.

Service installation section in this INF is invalid


If the player is showing up in your Windows' Device Manager under "portable devices" with a yellow "!":

1.) Right-click the yellow "!" and choose "update driver".
2.) When given the option to connect to Windows Update, choose "no, not this time" and click next.
3.) Choose "Install from a specific location (advanced)" and click next.
4.) Choose "Don't search. I will choose the driver to install" and click next.
5.) Click the "Have Disk" button. Browse to C:\Windows\inf and choose the file marked "wpdmtp.inf"

I can't believe the generic players have such crappy support when so many people have this problem! I think the Windows file problem might be caused by "compressing old files" when you do a disk cleanup.
