• USB Mass Storage Device problem

  I have the HP Pavilion Elite E9120f desktop computer. Whenever I start the computer, it shows that I have USB mass storage drives, G, H, I and J. However, there is no attached USB mass storage device. No one knows why this happens? I just usually click on the removal of the safety equipment and remove false devices. I get the message "this device can now be deleted without the computer problem. This machine runs Vista and has a 1 terabyte of hard drive. Thank you

  Bart, have you checked in 'My Computer' when this happens to see if the drives are there?  Almost looks like you have a virtual drive on your computer program.  Check also in start/startup to see if he is there that nothing listed that could cause this to happen.  Four readers Ghost is really strange.

• Problem ejecting USB Mass Storage Device [Unlocker doesn't work]

  Hey everybody,

  Just like everyone else, I get a pop-up message when trying to eject my external hard drive WD: "problem ejecting USB Mass Storage Device. Windows can't stop... "and so on." This does not work when I've only sailed on the disk, but it does, for example, when I made a mistake - check or make a backup. I already checked the forums, but unlike everyone else, third-party programs do not work for me.
  I did the following:

  -closed open task

  -disabled virus scanner

  -used Unlocker and Process Explorer, but he can't find any process that locks my drive. What happens here?

  -rebooted in safe mode

  -disabled indexing

  It makes me crazy that I have to restart whenever I want my drive to eject.

  Oh, and I use Windows 7.

  Can someone help me solve this problem?

  Hello

  (1) is limited to any specific USB device?

  (2) did you try to connect the device to a different USB port and check if you are facing a similar question?

  This problem may occur if there are handles open with all the files in the USB (Universal Serial Bus) mass storage device are in use by another program. Follow these methods and check if that helps.

  Method 1:

  I suggest you run the hardware and devices Troubleshooter to check if it helps.

  Open the hardware and devices Troubleshooter

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

  Method 2:

  I suggest you to check and clean the boot if any third-party program is causing the problem.

   

  How to troubleshoot a problem by performing a clean boot in Windows Vista and Windows 7

  Warning: After you used the clean boot in order to solve your problem follow step 7 to reset the computer to start as usual.

   

  Connecting and disconnecting USB devices:

   

  Most USB devices can be removed and disconnected at will. When you unplug the devices of storage, such as USB flash drives, you should be sure that the computer has finished saving all the information on the device before removing it. If the device has an activity light, wait a few seconds after the light has finished flashing before unplugging.

  If you see the icon remove the device safely in to the far right of the taskbar notification area, you can use this to ensure that devices have finished all operations in progress and are ready to remove. Click the icon and you will see a list of devices. Click the device you want to remove.

  You can use any USB port when you plug in a device you have installed beforehand. However, the first time you connect a device to a particular port, Windows will install the driver for this device again.

• External USB HDD PX1269E - 1 50 cannot be recognized on computer

  Hello

  I recently bought an external hard drive, Toshiba 500 GB external USB Hard Drive PX1269E - 1 50 I want to use it on my Pentium 4 3.6 ghz memory 1 GB 400 GB internal hard drive and motherboard ASUS P4P800.
  I installed Windows XP Profesional SP2 on this PC.

  We have 4 pc at home and he answered on any of this.
  The next problem is that after I pluged in the USB 2.0 conector, nothing happens? In the close computer store, I asked the seller to try it on one of their computers and the seller pluged it in one of the laptops and my external hard drive has responded immediately!

  After the test to the computer store, we have purchased a pci usb 2.0 card because we thought it was the problem of usb, but after installation of the usb hard drive adapter has failed, either.

  What could be the problem?

  Hello

  The dealer has tested the HARD drive and it worked.
  It seems the exterior works of HARD drive and can be recognized on the computer.

  In my opinion it s is not a HARD drive problem. For the most part this external HARD drive needs more power that can provide a USB port. My brother uses external USB HDD and it was delivered with a cable from USB 2. His HARD drive must be connected to the 2 USB ports on the laptop.

  I think that if you have a single USB plug cable, so you should use an external power supply for the HARD drive or try to connect it to the USB hub with external power supply.

  Maybe it will work

  Hi Troy382438,

  1. is this startup crashes before windows loads?

  2. you have SP2 installed on your computer?

  If windows hangs at the POST (Power-on-self-test), you may need to update the drivers from the motherboard.

  If windows crashes after windows loads, you can try the following steps.

  Step 1

  Install SP2 if it is not installed.

• "This USB mass storage device can transfer information faster if you connect it to a USB 3.0 port Superspeed ' when the device is already connected to a USB 3.0 port.

  I just bought and installed a USB 3.0 card. It is the Startech PEXUSB3S2 PCIe card. I installed the card in a PCIe 2.0 X 1 slot. The manual says it's exactly the slot, that it supports.

  The Manager device displays NEC Electronics USB 3.0 Host Controller and NEC Electronics USB 3.0 Root Hub are installed and are working correctly. I have a Thermaltake BLACX5G 5 G USB 3.0 hard drive caddy. The transfer rate is only 35 MB/s using the HDTune benchmark. It is a USB 2.0 speed.

  When the player is turned on, windows displays the message "this USB mass storage device can transfer information faster if you connect it to a Super speed USB 3.0 port»

  For some reason, the system doesn't see the caddy to drive USB 3.0 as being plugged into a USB 3.0 port, when it actually is.

  I remember having this same problem with Windows XP, when I bought a USB 2.0 card. The only thing that fixed it at the time was upgraded to XP SP2.

  This should not be a problem because I know that Windows 7 pro 64-bit supports USB 3.0.

  My motherboard is an ASUS P5QL-EM support an Intel Core 2 Quad and 4 GB of DDR2 memory. According to the manual owner the PCIe x 1 slots support architecture 1.0 and 2.0.

  Edit: I just tested the external hard drive and expansion card USB 3.0 on my motherboard Gigabyte of friends running Windows XP. Everything worked perfectly, no problems at all.

  Here, there is a problem with Windows 7 or the motherboard. Still unresolved, currently installs a floppy drive so I can update the firmware of my motherboard.

  I checked the implementation of the card several times, removed and installed in another motherboard to test, then removed and reinstalled again in my motherboard ASUS check several times for a fit course.  It still does not work. I have just completed update the firmware of the motherboard with the latest version, and I also did a new install of Windows 7, install the drivers USB 3.0 immediately after installing Windows over. None of this solves the problem.

  I'm running out of ideas on how to fix this without doing something drastic as a replacement for my motherboard. I don't want the speed of USB 3.0, but I don't think I'm ready for an another two or three hundred dollars to get it.

  I've been all over the ' net trying to find a solution and read tons about USB USB 3.0 specifically and in general. I can find no reason why the drivers would install and report that they are working correctly, but fail to connect to 3.0 speeds. I think that this would generate a certain type of error instead of such a strange symptom.

  EDIT:

  Here go us. I knew that is was a bad idea to buy one main (ASUS P5QL-EM) card that had to be overclocked to 1066 MHz for DRAM memory. I did all this work, and every time I reset my BIOS or updated it would always be the frequency DRAM back to where it should be (1066). After a reset of the computer was the starter and I just let it start instead of setting the DRAM frequency and, suddenly, USB 3.0 card worked perfectly. I confirmed this by setting the frequency to 1066 and looking at the USB 3.0 card fail again. I guess it must have something to do with the clock being sent to the PCIe bus.

  In any case, the USB 3.0 card works perfectly and gives me a transfer rate HD Tune to 99 MB/s on a drive from WD SATA 7200 RPM and 86.1 Mbps on a Samsung drive hard 5400 RPM / MIN 3,5 "SATA. These are the same reference points I get when these drives are connected to my internal SATA connectors. I'd say USB 3.o works perfectly now and maxing out the hard drives performance.

  Thanks for any help.
