  Hi FAH300,

  If you are not able to format the drive, there may be a hardware problem.

  I suggest formatting the disk using the instructions linked by wb2001.

• Wireless dead after reinstalling Windows. Device Manager can't see the map

  Hello

  I have a laptop model Lenovo 3000 N200 14W 0687.  It was teeming with virus so I wiped the hard drive and installed Windows XP Home Edition from scratch.  Now Device Manager can't see the wireless adapter and Wireless does not work.  I tried to download and install the Wireless driver on the Lenovo site (I don't have a disc of relocation); but I got errors.  Anyone know what could cause this and a fix?

  If you are interested, here are the details of what happened when I tried to download and install the drivers:

  Device Manager gives me the adapters three following network:
  Network adapter 1394
  Broadcom NetLink (TM) Fast Ethernet
  MAC bridge Miniport

  None of which resemble wireless cards. So I used the link http://consumersupport.lenovo.com/ot/en/DriversDownLoads/Drivers.htmlto try out. Enter my serial number L3X3516 took me to a support page client lenovo that says

  Total 13 drivers need to be repaired/upgraded, 9 drivers in need of repair, please click the "Download" button to begin to repair

  One of them was this:

  Intel (r) PRO/Wireless 3945ABG Network Connection

  I downloaded it and it says: 'the contents of this file cannot be unpacked. the executable file that you are trying to run has been damaged. You can get another copy of the file, verify its integrity, and then try again"

  So I used google to find this site:

  http://www.getpcmemory.com/drivers/download-Lenovo-3000-N200-type-0769-notebook-Windows-XP-Vista-DRI...

  who told me that my computer is a Lenovo 3000 n200 Type 0687.

  Using google once again, I found this page:

  http://www-307.IBM.com/PC/support/site.WSS/document.do?lndocid=MIGR-68011

  which was another version of the driver. So I downloaded and unpacked it. I then took a glance at the .txt guide provided with the driver. It is said:

  1. Start Windows XP and log on with administrative privileges.
  

  2. Double-click the driver package to extract it to your hard drive.
  

     The default location is C:\SWTOOLS\DRIVERS\WLLANINT
  

  3. Click Start, then click Run...
  

  4. Specify SETUP.EXE with the full path name where you extracted the
  

     package in step 2, and click OK.
  

     Example: C:\SWTOOLS\DRIVERS\WLLANINT\SETUP.EXE
  

  5. Follow the instructions on the screen to complete the installation.
  
  Unfortunately, there is no setup.exe file in the folder so this has failed.
  
  Regards,
  
  satherb
  

  configuration > wireless lan support > enabled

  for display drivers, re - install it: http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-67978

  and on Device Manager, please, provide the device id. (eg PCI VEN_8086 & dev_2929 & subsys)

  or if you know which wireless adapter you have, download drivers from the download page, then re - install.

• Why my XP does not recognize a Toshiba 500 GB USB external drive... it does not appear in disk management or in computer

  Bought a new Toshiba 500 GB drive external usb.  My XP desktop won't recognize/find this disc.  It does not appear when you view the disk management or work station.  I also have it on my new laptop (Vista) and it has been found immediately.  My research online only tells me to find the external drive in disk management and assign a drive letter to... but I don't think to assign a letter! Toshiba says that the drive is compatible with XP. I have another smaller disk capacity that work perfectly on the XP machine.  Please tell us what should I do to have my Office XP recognize the
  is the new external hard drive.  E-mail address is removed from the privacy * or * address email is removed from the privacy *.

  Three things that you have not yet mentioned are

  1. don't change you the registry suggested by the KB Article (see: a computer that is running Windows XP cannot detect a USB flash drive, an iPod from Apple or an external hard drive)?  I suggest do it manually instead of using the FixIt.

  2 represents the drive recognized in the Device Manager (start > run > devmgmt.msc > OK)

  3 is the drive recognized in your BIOS (press the corresponding key on startup).

  Reformat to FAT32 was probably not necessary (and you'll probably want to re - format to NTFS before use).  XP has no problem with large (> 500 GB) external USB drives.

• Toshiba Canvio USB external drive does not work well

  I hope this is the right forum for this question
  Please help me with my external hard drive, Toshiba Canvio usb e05a032bau2xk.

  It worked fine, but not now.
  My OS is win xp, sp3, home ed.

  The Toshiba drive is more steady and is almost impossible to work with now. I checked with Device Manager that says the drive is working correctly.

  I've uninstalled and reinstalled the driver, cleaned and Defrag the disk (when I was able to access) but it works still very badly now!

  What else can I do to find out what is the problem with this Toshiba drive and return it works reliably?

  Thank you

• Unrecognized USB mass storage device

  I have a Maxtor 3200 external drive that works very well with Windows 7 Home Edition.  However, today I can not get recognized by Windows.  It is listed in the Panel--> open devices and printers, and watch "the device works properly."  He also appears in the list on the icon ot safely closing devices.  But it does NOT show in Windows Explorer, so I can't access any data on this Maxtor external hard drive that I have to be able to do.

  When I connect a USB, Windows recognizes it.

  Hello

  Method 1:

  Run the fixit for the following Microsoft article, and if that helps.

  Hardware devices do not work or are not detected in Windows:

  http://support.Microsoft.com/mats/hardware_device_problems/

  Method 2:

  Run the hardware and devices Troubleshooter and check if that helps.

  Open the hardware and devices Troubleshooter:

  http://Windows.Microsoft.com/en-us/Windows7/open-the-hardware-and-devices-Troubleshooter

  Method 3:

  See the following article from Microsoft and then change the letter of the external drive and check if that helps.

  Change, add, or remove a drive letter:

• L750 satellite fails to record the external DRIVE of 1 TB as a HARD disk drive

  Hello

  I wonder if anyone can help with this problem?
  Please excuse the absence of computer terminology!

  I have a Toshiba Satellite L750/l755 (don't remember which) and my external hard drive recently failed to register as a reader. (Samsun Story Book 1 TB)

  For more than a year, it has worked without problem.
  Now, when I turn it on, it shows momentarily as a reader, even to the point of show files that it contained.

  If I'm fast enough, I can even open one of the folders, but then the reference of the car goes with everything, and I receive a notice indicating that 'G' refers to a drive that does not exist.

  Shows Device Manager hard drive external, and all, apparently, allegedly, works fine! I tried to assign a different drive letter, but nothing happens.

  My laptop accepts there is a reader connected, but fails to save it as a reader!

  I tried to use Knoppix to see if that could access it, but can't find where to change the bios to boot from the disk!

  I am at my wits end because I'm to halfway through writing a book and everything is stored on the outside! (Yes, I know now! "It is not safe to do!)

  Please can anyone suggest a solution?

  Thank you very much in anticipation.
  Alec.

  > I tried to use Knoppix to see if that could access it, but can't find where to change the bios to boot from the disk!
  While turn on the power, press F12 to get a menu where you can change the boot device.
  Then you should be able to boot from the CD from Knoppix (or other Live bootable drive)

  But have you tried to connect this drive external DRIVE on another computer?
  In my view the issue looks like problem with HARD drive and no system or laptop issue.

• My recently installed backup USB WD drive is a show in my computer. What can I do to make it appear?

  I have a Dell D830 running Vista Ultimate.

  Try to connect to another computer. If it does not, the cable or the hard disk enclosure can be bad. Try using another cable first.

  If it shows very well: go to Device Manager, expand Universal Serial Bus controllers, search for your device, do a right click and uninstall, then restart, it needs to be reinstalled.

  If that doesn't work, uninstall everything under USB controllers, then restart your computer.

• Device Manager can't see the DVD ROM

  I have a HP Pavilion dv9628nr notebook PC, with the version of BIOS F.31, running with Vista SP2.

  He stopped recently to recognize the DVD ROM, which does not show even as a device in Device Manager, so I can't uninstall or update the drivers.

  In the BIOS it is listed as a boot device, so it's there somewhere.

  I tried the Fix Windows, what has not worked as well as regedit to delete the LowerFilters registry entry (there was no UpperFilters one listed), but none of this has given me my DVD DRIVE in Device Manager.

  I wanted to try to disable AHCI mode for the drive controller in THE system BIOS, but it is not an Advanced tab available to get to this. And I don't know if this will solve the problem anyway.

  Suggestions appreciated. Thank you and Merry Christmas.

  Hello

  First, reset the defaults in the bios as follows.

  Shut down the laptop.  Tap here to f10 as soon as you start Notepad to open the menu of the bios.  Press f5 to load the default values (sometimes it's f9, but the menu below indicates the correct key), use the arrow keys to select 'Yes' and press ENTER.  Press f10 to save the setting and still use the arrow keys to select 'Yes' and press on enter.

  Check if the drive now appears in Device Manager - if it doesn't, try the following.

  Even if the optical drive is listed under bootable devices, it can still have a hardware problem

  An option here, you could try this will give a good indication that the problem is with Windows or the optical drive itself.

  Create a bootable Ubuntu CD

  The Ubuntu CD that you create should work as you start the laptop (IE outside of the Windows operating system), so if this works do not, the problem is almost certainly a hardware with the DVD player problem

  On another PC, follow the procedure on the link below to create a bootable Ubuntu CD and follow the steps described in the part 3 to 'Try' to see if this OS runs from CD.  The 'try' option does not need to install on the hard disk, it just runs from the CD.

• Windows 7 USB Flash drive - if I click on Scan and difficulty after you insert the disk, it erases my files

  Original title: Windows 7 USB/Flash drive problems

  In Windows 7, if I plug in my USB drive, the message box appears titled ' do you want to scan and difficulty of removable disk (e :))?»  If I click on Scan and Fix, he deletes my files (or so I thought).  I hope that the files are still there and I have simply can't see because the drive is FAT32 and not NTFS (it says that most of the drive is NOT of free space, so I assume that the files are still there).  What should I do to see / access files?

  Note: A reader, I never selected "Scan and repair"... so I can still see/access files.
  On the other drive, however, the first time I plugged it on Windows 7, I clicked Scan and Fix and it erased all the files on this drive (I guess).  This of course got me very angry.

  Hi MichaelGramm,

  It seems that the file format has been corrupted. You might consider formatting the drive in NTFS file system and check if this solves the problem. For Windows 7, the best choice for hard disks is NTFS.

  Note: Make sure that you back up the data before formatting the disk.

  See these articles for more information on formatting disks and flash player:

  Create and format a hard disk partition

  http://Windows.Microsoft.com/en-us/Windows7/create-and-format-a-hard-disk-partition

   

  Formatting disks and drives: frequently asked questions

  http://Windows.Microsoft.com/en-us/Windows7/formatting-disks-and-drives-frequently-asked-questions

   

  Caution:

  Formatting erases all existing files on a flash drive. If you format a flash disk that has files on it, the files will be deleted.

  Hope this information helps.

• Windows 7 64 bit does not recognize the USB external drive HARD Stor E art 3.5 "

  I buy the art external disk HARD Stor E 3.5 "and spend a few days in windows does not recognize the HARD drive. Try to connect the drive to other USB 2 ports and nothing happens. Use a USB to see if has been a problem with the USB ports, but all 3 are OK. Try it on the laptop Asus and windows 7 recognizes the HARD disk. I formatted the drive in NTFS FS. In managing records do not show the external HARD disk. What can I do to fix this?

  My laptop is a Qosmio F60

  This is a really silly situation. It can be recognized by other laptops but not your Qosmio.
  According to the description of your HARD drive when connected simply doesn t exist for your Qosmio laptop.

  Some other HDD is recognized correctly?
  What you can try is to reinstall the chipset driver, restart the laptop and test it again.

  Since when you have this problem? Some installed updates of the last days?
