Windows 7 does not recognize the USB 32 GB

I have a Sandisk Cruzer 32 GB USB stick key, as I would like to transfer a single file of 9 GB between my two laptops.

The memory stick appears and works very well on a laptop (Acer) - while working.  However it does not appear on my other laptop (Compaq) after plugging him.  Laptop computers are Windows 7 Home Premium 64-bit, both use the NTFS system and the memory stick was formatted in this way also.

I used the disk on the Compaq Management and (after a while) the memory stick appears.  In order to avoid any conflict between the drive letters, I have re-assigned to the M: drive and that seemed to work.  However, it does not ALWAYS appear in the Windows Explorer, so I can't transfer any files to it!

Any help would be appreciated!

Thank you.

Hello Stephen,

When looking for hard drives, USB flash drives or CDs and readers of DVD using Windows Explorer, you may notice that some readers are not in Windows Explorer or the drive may disappear after a short period, or when Windows resumes or Hibernation. This may be caused by the following:

  • Your player does not have a drive letter assigned in disk management
  • The player can be disabled or offline
  • Your USB driver is maybe corrupted
  • Damaged registry keys may be the cause of problems with the connection to your CD-ROM or DVD drive
  1. When you connect other USB devices on the computer, they work well?
  2. What is the status of the Sandisk Cruzer 32 GB USB drive in the Device Manager?
  3. You have Kies installed on the computer?

  • DreamColor LP2480zx does not recognize the USB for calibration

    Hello

    I have a DreamColor LP2480zx, which does not recognize the USB connection to the computer during calibration.  I have my eye HP connected through this monitor, so I know the connection and the cable is good and mouse, keyboard.  My setup is like this:

    Reference Dell 690 running 64 bit + Windows XP

    DreamColor LP2480zx

    Apple Cinema Display 23 "

    I bought the DreamColor used, and in all other respects, it seems to work very well.  The original owner didn't have it calibrated within a certain time, but said that having had no problem with the previous calibration.  I installed the last APS (version 2.0) and updated to the latest firmware.  These updates produces no change in recognition USB problem.

    The interesting thing is, I was able to calibrate the Apple Cinema Display, using the same configuration of connection (mouse, keyboard, and HP eye connected to the computer via the LP2480zx) APS was able to see the USB connection and this very well calibrated monitor.

    I had trouble with this problem for a few days.  I've looked around quite a bit online and found a few others who have this same problem, but I did not yet find someone who can point out a solution.  If anyone has had this same problem, or has heard of results that correct it, please let me know, because it's very frustrating.

    Thanks for any help

    An update to my previous post, I realized a work around for this problem.

    Apparently, this problem has to do with the Dreamcolor screen and/or software APS do not like working with 64 bit systems.  I'm not saying that it is always the case, but I saw the other posts on this problem on 64-bit systems, and I spoke with two other people personally who told me that they also had the same problem, try to calibrate its Dreamcolor monitor when it was attached to a 64-bit system.  HP does not seem to be concerned about this problem, because they do not even recognize its existence, but since I'm far from being the first to report this problem, he's obviously not a one-time problem.

    My solution was this: I had connect the monitor to a regular running XP 32 bit system.  After I did, I could re - calibrate the monitor without the problem of USB connection.  This isn't a very good solution because not everyone has access to several machines, running different operating systems.  But it's a work around, and it worked for me.

    Hope this helps other people who have this same problem with their Dreamcolor monitors hooked to their 64-bit systems.

    Clay

    PS- I posted this as resolved, only because I was able to calibrate my monitor.  It's not really solved the problem, but it gets the monitor working again.  Maybe HP will address this problem in the future, but I'm not holding my breath.

  • Satellite A200-1AE does not recognize the USB 2.0 flash drive

    I have a problem because my satellite A200-1AE with Microsoft Vista does not recognize the USB 2.0 flash drive. He asks me a program/software!
    The same USB works without problem on other computers with vista!

    Someone knows what to do?

    Hello

    First of all, you must disconnect all USB devices and must remove the USB ports and controllers in the Device Manager.
    After this procedure, you must restart the laptop. After a new restart the Vista operating system should recognize the USB ports and should reinstall USB drivers again.

    Then you must update the Vista to the State! All fixes and patches must be installed. Please note that you will have to visit the MS Update site for all patches

    Notes; MS has released a beta of Vista SP1. I installed it on my laptop and it has solved several problems.

  • Install Windows 8 does not recognize the system drive

    I built a new machine (chart below). Since this is a new machine and not an upgrade, I bought Win 8 Pro 64 bit OEM to do a clean install. The SSD is my system disk that Windows 8 will be installed. Four data drives are mirrored, two for the other two. Construction went perfectly. The BIOS recognizes all six disks: 1 SSD, 4 HDD, 1 DVD.

    Insert and boot the disk of Windows 8. Accept the EULA, enter the product key. Arriving at the page "Where do you want to install Windows?", only four hard disks are listed. The SSD (installation to go) is not found by Win 8. ??? I tried to change ports SATA, cables, power supply - no difference. For each new change of hardware, the BIOS still sees everything. This isn't a hardware problem.

    The question remains: why the installation of Windows 8 does not recognize the SSD drive. All five disks are on AHCI. I'm not in RAID.

    I spoke with crucial technical support of all (manufacturer of the SSD). They were also surprised that the drive does not appear in the list.

    Does anyone have a solution? I spent all the money on hardware, as well as the new version of Windows and I cannot install it.

    This is the real kick in the teeth: Microsoft won't support me. The OEM of Windows 8 version is the same as manufacturers, such as Dell or HP. Support told me I had the support of the manufacturer. HA! I am the manufacturer. Either that or upgrade from an earlier version of Windows. This means that any that a new construction machine will get ZERO assumption of Microsoft. All just great.

    Thank you in advance for any assistance.

  • 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?

  • Windows 7 does not recognize the installation discs

    Hello

    I have a problem, and I don't know if there is a solution, but here goes.

    My laptop is a HP DV6-7029WM Windows 7, 64 bit.

    The hard drive was dead, and he was replaced last month.  I sent it to HP.  C is the hard drive, and was originally the recovery on D. Removable media were on E, and when I connected a USB stick or memory card reader it would on F.

    When I came back, hard drive was on C as it was originally, and there was no recovery drive D. D is now my removable media drive. When I put in a USB stick or a memory card reader, which is now on the E drive.

    After I bought this, I put the recovery on a USB key, but I've accidentally thrown out. (My mistake) So I ordered the installation diskettes after that I return my HP PC.  I had 2 DVD system recovery disks and an Application and a recovery DVD Drivery.

    I want to reinstall Windows back to the default settings. I put disc 1 (System Recovery DVD) and close.  I reboot and it goes directly to the office. I hear the whirring disc, but nothing happens.

    I go to the control panel > Recovery > advanced retrieval methods. I click on restart, and it loads files and then says DVD set, which I do. He told me that he does not recognize the installation disc.

    I googled this problem and found a poster on CNET that had the same problem as I do. Also, I can't do a system restore.  My problem is the same as this poster on CNET.  I can read DVDs and CDs.  Those that work very well.

    http://forums.CNET.com/7723-19411_102-568059/Windows-7-installation-disc-not-recognized/

    The files are on the DVD, because I see them.

    I don't know what to do. Should I send my PC back? Can I do to solve this problem?

    Thanks in advance.

  • Aspire One d255 does not recognize the usb connected external ssd drive

    I want to replace the original HDD 160 GB with a 120 GB Samsung ssd 750 evo but bios and win 10 does not recognize the ssd drive as an external drive connected via a usb connection, so I couldn't create an image of my internal hard drive.  Is there a way to clone my hard drive SSD, so I can exchange the disc later?  I need to update the bios, install a missing driver, etc. ?

    I used two different connections: one is a 2.5 "SATA case disc that I used with a disk 2.5" HARD and works very well with the HARD drive and the other is SATA/IDE connector combination with cables for SATA and power and none of these works.  I read in another forum during my research that the Aspire One d255 doesn't recognize any external SSD connected through a USB either.  Since my netbook has no data, and I had just a pure 10 Windows installed on his drive HARD internal, I removed the 160 GB HARD drive and replaced by a 120 GB SSD and installed another Windows own 10.  It worked and my system boots now in less than 20 seconds.   We can close this thread now since I now have a faster machine fully function.  Thank you!
