Satellite L20-100 cannot access a USB Flash drive

I recently bought Toshiba Satellite L20-100
I installed a USB in Kingston datatraveler flash drive and windows recognized it without problem.
but when I open my computer there is no icon for the reader (it works on another computer well).
the drive is recognized in Device Manager, but it is not given a drive letter.
When I open disk management and try to give it a drive letter it still does not show on my computer even after a reboot.

Although I can access the disk management flash drive and can open, copy & paste the files & to her.
same problem happened with a card reader.
other USB devices like cable modem & mouse work well

What is the solution

Hello

Is it possible that the USB is not formatted? Try changing the file system on the USB key.
You can also try to change the drive letter because the letter assigned automatically sometimes gives some conflicts with other readers.

Second possibility:
You can try to clean all the USB stored device settings and let Windows refresh their.

Create a file with Notepad containing the following lines and save it as a BOOKMARK. REG
-cut after this line-
REGEDIT4

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Environment]

"DEVMGR_SHOW_NONPRESENT_DEVICES" = "1".
-cut before this line-

Double click on FIX. REG and say yes to the merge into registry question.

Unplug ALL USB device.
Open the Device Manager.
View, show hidden devices.
Uninstall all devices under USB controllers.
Uninstall all devices in hard drives that you know are not present.
Uninstall all devices in storage Volumes. Say no to all reboot prompts until you are finished.
In addition, if a storage Volume doesn't uninstall, ignore her and move on to the next.
If you have a yellow? with unknown devices, uninstall all of the entries there as well.

  • Difficulty accessing FAT32 USB flash drives

    I can't access my usb on my PC flash drives, which are formatted FAT32. NTFS works very well. When I try to open the drive FAT32, windows asks me to format it. I have no problems to open on my laptop. I tried formatting in FAT32, which translates the format error and incomplete. I tried to remove the USB drivers.

  • 4 error code when a client system tries to access a USB flash drive

    I recently installed Windows XP in a guest operating system, using Workstation 6.5.5, but I am not able to connect a USB device to the host (8-64-bit Windows) system.   I have another desktop computer with a 64 bit Vista host and a Vista 32 bit comment system where it has never been a problem.  There must be a setting that I can't find which would allow this simple task off a flash of the host drive and its connection to the host. Under settings, I allowed to recognize all USB devices.

    Gordon

    Houston, Texas

    If the host system's USB 3.0 so as a workaround you may need to buffer the USB device between the host and he with a Hub USB 2.0, then the comments of Windows before Windows 8 OS should be able to access the device.

  • Satellite L675 - 11 H - cannot access and/or played on USB flash drive files

    Hi all

    I recently bought a Toshiba Satellite L675 - 11H and tried to transfer files from a USB Pendrive on my hard drive from Toshiba. The files were already transferred from my old laptop (HP - XP) on my USB flash drive.

    Unable to access the USB flash drive to any of the USB ports that I connect my new laptop flash drive. What could be the problem here? Thank you for your help or tips!

    Hey Rush,

    Can you post more detailes about this behavior? What happens if you connect your laptop HARD drive, you don't see that Windows installs the drivers for the new USB device or do you have an error message? If you have connected the USB check of Windows disk management if she s recognized there (Control Panel > system and security > administrative tools).

    Have you tried other USB devices such as USB mice? If they don t work too the problem might be connected to the USB ports. In this case, you must delete all the USB ports on the Device Manager and restart your laptop. Also the chipset driver update might help.

  • Satellite L20-100 can be started from a USB external hard drive?

    I recently bought Toshiba Satellite L20-100 and I wonder if:
    1. is it possible to boot this machine from a disk usb external drive?
    2. it is possible to attach another internal hard drive?

    Assuming that the two answers above are 'no', how can we solve the following problem: I need hard drive space, I need to launch 3 systems of separate Wxp operating on the same machine (Toshiba Satellite L20-100).

    You are right. The answer is no. Only thing you can do is to create 3 partitions and install on each a favorite OS. Using the Boot Manager, you will be able to choose one that fits in the beginning upward.

  • Strange behavior USB Flash Drive Satellite A100-626

    Hello

    I did install Windows Vista Business Edition on my Satellite A100-626 (PSAA9) following the instructions provided in the Web page of drivers.

    So far, everything works as expected, except for one little (or no) question.

    When I ask Vista to 'Remove hardware safely' my USB Flash drive, a Popup appears telling me to remove it. So far, so good :D

    The only thing is that the flash player is not put out as could be expected and and yellow question mark appears in Device Manager.

    Opening of the question mark can read what follows:

    "Windows cannot use this hardware device because it has been developed to remove safely, but it has not been removed from the computer. (Code 47) To resolve this issue, disconnect the device from your computer and plug it in again. »

    Following the instructions above, the light turns off, lol...

    Someone else met this strange behavior? If so, any solution?

    I tried a few USB flashes that run well on XP and they both do the same thing.

    Thank you, Nuno!

    Hi Nuno

    It's very strange. I have the Satellite A100-504 (comes with Windows XP Home edition). Last week, I installed Vista and all the stuff followed Toshiba document instructions facilities. I use the mouse wireless, external HDD USB web cam. With the help of these external devices together I never noticed a similar behavior.

    You have the same situation with all the USB ports?

  • How to create a backup for Satellite L20-100?

    My Satellite L20-100 crashed & it took me 24 hours to recover (using the provided factory product recovery CD) & for reinstalling other software & updates.

    Now I'm afraid, it may crash again & I have 11 GB of software. I had a function on my Windows XP console start > programs > Accessories > system tools > create backup disk (or recovery) before it crashed, but it is no longer present.

    ANY THOUGHTS? URGENT PLEASE!

    I recommend you to use a very good third party software called NORTON GHOST. I use it for a year. You can create own recovery DVDs and use any time when there is a problem.

    I do the same thing. This created individual image is recorded on the partition d. If I want to have the new facility that I simply start GHOST and the partition c is crushed.

    If you need more info please let me know.

  • Satellite L20-100: Nero does not recognize the UJ - 841S

    Hello
    Our computer is Satellite L20 - 100... He has a special CD burning program Sonic Record and it does not crush. I want to use Nero or Alcohol 120, but the computer does not support them.

    Is there a special driver or something that can allow the use of these programs? Or how to use Nero on my laptop? I'll be happy if someone can help me...

    Thank you

    Hello

    Nero it works without any problem on your laptop and you don t need no additional driver.
    But maybe the different burning applications have a bad influence on the only burning software. Try to use only a single application.

  • Satellite U400-10j - how to boot from a USB flash drive?

    Hello

    I have a Toshiba Satellite U400-10j.

    I have Ubuntu on my USB flash drive, now I want to boot from it.

    I can't find the option in the BIOS to boot from the Usb flash drive.

    Second, I noticed that the phone also has an internal memory card reader.
    I could load Ubuntu top then to start the memory stick as well?

    Your help will be very appreciated.
    Thank you.

    I think that it s not able to boot from a USB key on this laptop.
    The best way is to use a CD. There, you can start on this notebook and all other laptops.
    In the Internet there are many versions of CD of Ubuntu and other Linux systems.

    And as said Feliks, it s not able to boot from an SD card because it is not in the BIOS.

    Hello

    I agree with Akuma L20 supports a SATA controller and you need and 2.5 SATA HDD.
    Usually it s no matter which manufacturer is all 2.5 SATA hard drives must be compatible

    With regard to the 48-bit LBA:
    As far as I know that this could be just a problem with HDD IDE (P - ATA). SATA HDD should not be affected. So, theoretically, you could upgrade the HARD disk using larger than 128 GB.

    Regarding the upgrade of memory:
    http://www.orcalogic.co.UK/ASP/ProdType.asp?ProdType=20683&ft=m&St=3

    You need DDR2 533 MHz (PC2-4200) 200 - PIN SODIMM and you can use 2 x 1 GB RAM
