• Tecra S1: No drive letter for USB keys assignments

  Hello!

  Once from time to time, two of our portable Toshiba S1 will not assign a drive letter to a USB drive attached.

  Win XP Pro recognizes and loads the drivers, but they will not get a letter. Oddly enough, this doesn't always happen. Sometimes, a drive letter is assigned. It also happens with sticks that hard worked prior to fine, but it won't work again later, the.

  Obviously, uninstall the drivers help temporarily.

  Is there a permanent solution to this problem?

  Hello

  Have you already checked if there is a new update of the BIOS for your laptop model? Maybe update the BIOS can help. In any case I don't know if there is a solution, because as you know it's always more fun with USB keys. Some of them work well, and some of them are not recognized by the operating system.

• Cannot change the letter of the drive on a USB key in windows 8

  I have windows 8.  My wife has windows 7.  With each computer, I am unable to assign a number of drive on a used USB that I recently received.  My theory is that it's a disc designed to be spent as a backup drive that the OS of the computer can recognize but don't know how to interface with.  I was hoping someone might have some ideas.

  Each computer recognizes the drive, said it works fine with the latest version of the driver, and ready to use, but it does not appear as a disk on the DESKTOP.
  When I go to manage storage-> disk management, disk comes with two partitions in good health.  One is called EFI system partition.  EFI seems to mean "Extensible Firmware Interface".  I'm guessing that it is designed to act as the interface between the OS of the computer and the USB key.  The other is called primary Partition.  While all other readers list their NTFS file system, these two partitions do not list a file system, which makes me wonder if the operating system can recognize the format.   With a partition, if I click right, all options except "help" are grayed out.
  Any ideas?
  Thank you.

  Hey Joe,

• No drive letter for USB PCMCIA card reader

  I use a card reader Addonics AEPUDDU Digi - PCMCIA (USB for PC connection) drive with a desktop XP computer.  Now, when I plug in any card memory PCMCIA (I tried several), the card reader recognizes the insertion of the card (the Green led lights up), like the PC (the icon appears in the system tray), but it does not affect no matter what drive letter to the map, so I can't access it all (through Windows Explorer).  If I click on the icon to eject, I get the usual pop-up message ("Remove USB mass storage device"), still only refers to a drive letter.  Clicking on this message gives the 'Safe to Remove Hardware' popup normal.

  Moreover, this habit of work very well, and then several weeks ago began this strange behavior.  Some days it works OK, a few days would not work.  Sometimes restart would fix it.  Today, it doesn't seem to help.

  Why XP will not assign a drive letter to this device, and how do I fix?  Thanks for any help or suggestion...

  Moreover, this habit of work very well, and then several weeks ago began this strange behavior.  Some days it works OK, a few days would not work.  Sometimes restart would fix it.  Today, it doesn't seem to help.

  Assuming you are trying to read of the same type and media memory size that used to work and other USB devices plugged into the same USB taken work, it seems that the device failed.  That means Addonics offers technical support?

  I guess that you tried to connect the unit on different USB Sockets.

  Open the Device Manager (start > run > devmgmt.msc > OK).  I don't know where this device will be displayed.  Look in the hard drives and the Bus USB controllers.  Are there error icons?  If so, double-click the name of the device and see which appear under the heading "status of the device.

  If nothing is reported as bad, it is possible that uninstalling and reinstalling might help.
  Double-click the Device Manager entry and select uninstall.
  Then disconnect the device and reboot.
  Then plug in and let Windows recognize it and install it.

• Reformatted a hard drive now in a closed Chamber. Not an assigned drive letter. Installation in a NTFS folder empty?

  Hello.

  I have a few external hard drives. I want them to be little permanent on my laptop or desktop for creating media. The only way seems to be to not assign a drive letter and let windows assign/change it a whenever I connect it or assign a drive letter or install it in a NTFS folder. Currently only disk management is recognizing the readers, because they are not assigned or mounted.

  I have a few questions about the editing of this property. I want to have several drives working independent of drive c as possible.

  If a folder is placed on the c drive: 1. how many resources are required by c-drive?

  2. what concerns me is: these devices should not access drive c. drive c. If the mounted folder still behaves like an extrnal device? Or is it considered an internal c drive folder/position?

  3. I want a usb2, usb3, firewire400/800 or eSATA connection to have the maximum speed, not to be a bottleneck in a c drive thinking that she keeps "access itself. I'd rather have a c drive do it of thing and pull of external device, its weight as it is supposed to independently (or "independently" keepingin mind records temp and temporary files, etc...).

  4 is it windows search for NTFS files if the device is not connected? I guess not, and I would get a message saying something like "cannot access this folder, no content inside" or "please connect the device to access the contents of folder and it is mounted. What concerns me is: sometimes my computer does not start up if all devices are not enabled (usually after an accident, mistake, bad closure or a change of equipment). For example: I need my printer usb2 lights sometimes, or I just get a black screen in these situations. Then I get all the usual startup screens, etc.

  My alternative is to connect specific devices in a specific order to every time I use my computers for the purpose I want. Speed is my main concern, but I know that sometimes I can not connect external in the order because of what I'm doing, travel or I want to conserve their life and do not plan their use.

  Thank you.

  It's just a mount point, a symbolic link to the external volume.  Readers will work like any other drive, but they are assigned to a path to the drive rather than a letter, below all the NT object Manager handles this as a drive letter, the C: drive will do nothing to hold or store the link.  In a sort of way, that it would not much more different to a regular shortcut to another folder on another drive on your desktop, the office is on the C: drive, but when you access the file on the other drive via the shortcut it does not affect the C: drive.

• Cannot re - install Windows7 from USB key created with Dell Datasafe Local Backup

  Hello

  I created Dell Datasafe Local Backup recovery media and stored on a USB key.

  However my laptop Dell Inspiron has only USB 3.0 ports so when I try to boot on the USB it tells me: "cannot find the image of system recovery. "If you try to restore your pc from a USB 3.0 (blue) USB Port please connect to another USB Port, restart your PC and try Recovery.

  If my laptop has no former USB 2 ports and, apparently, Windows 7 doesn't come with native support USB 3 so how can I re - install my system using the USB that I made Dell Datasafe Local backup?

  I tried to make a set of Dell Datasafe DVD, but it is not I think that there is a bug in the routine of Datasafe Local Backup DVD recovery media.

  Am I better off Dell asking to send me a re-installation OEM DVD set? How would I do that?

  Thank you.

  First of all try to change this setting in the BIOS Setup disable USB 3.0 features to install Windows 7 from a USB Flash drive

  Regarding the DVD of Reinstalaltion demand that I recommend. For US customers, there is a relocation brackets online application form.

• Cannot change drive letter external (Windows Vista)

  I connected an external hard drive to my laptop (3.5 "), but it can not display in Windows Explorer.
  I have Windows Vista installed on my laptop

  The external hard drive is recognized in disk management, appears in good health, but has no drive letter assigned.
  When I want to change the drive letter, this and every other option is grayed out, except the option 'Delete Partition '.

  All the world is facing this problem before?

  Thank you

  Nielke

  Hi Nielke,

  I'm sorry to know that you still have the problem.

  You can try plugging the external drive to another PC to see if the device works it.

  If it is detected on another PC, you will need to take backup of the data on the external hard drive and try to format the drive by following the steps mentioned above to the PC where it detects.

  After formatting the drive, check to see if it detects is to change the drive letter.

  Hope this information is useful.

• HP Pavilion m7667c, try to install Vista 32 bit. No OS - the charge not assigned drive letter.

  My HP Pavilion PC m7667c console was at the origin of many blue screens. After several diags that does not solve the problem, I replaced the power supply because the block is dead.  Then replaced the motherboard.  The XP PC operating system will not recover because the BONE had already improved Multimedia Pro XP to VISTA. I can get the VISTA OS to run from my CD to upgrade to VISTA, but the operating system is not found, because there is no drive letter assigned to the drive.  I tried a replacement for the HD signal cable but no help.  I can't on a screen so windows help.  At this point, I'm ready to reformat the hard drive then maybe I could partition and assign a drive.  Any suggestions?

• Windows 7 will not assign drive letter to e-SATA drive

  I have a Seagate 1.5 TB SATA disk mounted in a Thermaltake case which has an e-SATA connection. The drive has been formatted NTFS on a Windows 2000 computer and a backup on this computer has been correctly written to disk. When I connect this drive to my 64-bit Windows 7 computer (Gigabyte GA-P55M-UD2 m/b using an e-SATA port connected to the Gigabyte SATA2 chip) Windows recognize the drive where the disc is displayed in 'Remove hardware safely', but Windows 7 does not allocate a drive letter.

  The disk appears in disk management (currently Disc 3) without a drive letter. When I right click on the blue band to the right of the box Disc 3, Windows cross-hatches the white rectangular box below the blue band. When I click on 'change drive letter and paths' I get the following message «the operation failed because the view is not updated...» "None of the proposed remedies work.

  The results are the same regardless of whether I start the computer with the drive connected and running or hot plug disk.

  My e-SATA 1 TB Fantom drive works fine on this computer.

  I would appreciate any suggestion you may have.

  Hello

  Look in Device Manager if there is an item under "storage volumes", called "unknown device". If there, uninstall the driver to do this and as soon as I reconnect the windows disc and see if it assigns a drive letter. If it isn't

  Try this;

  Go to Device Manager

  (1), look for an entry that says "Unknown disc" or something similar. This entry may not be marked with the error icon.

  (2) after you locate the entry, right click and select "Uninstall".

  (3) after you have uninstalled, press F5 or select "Search the hardware changes" in the action menu.

  (4) the pilot is then reinstalled correctly.

  P.S - I found these answers in other forums showing the same error message. Try them and let me know if it was just a waste of time.  :-)

• Cannot install Windows 10 from USB key on the MacBook Pro mid 2015 with OS 10.11.4

  I get this Windows error message, after formatting the partition with NTFS BootCamp: "we could not create a new partition or locate an existing one. For more information see the installation log files. "I think I have meet the hardware requirements for Windows 10 and defined a 50GB partition - don't know what the problem is.

  See map of partition of the disk. There are GUIDS. The drive is probably Master Boot Record.

  Even if it is already GUID, I got the same message the first time that I went to install Win 10 on a disc that I knew (and verified) as GUIDS. Win 10 would not install until I've repartitioned the drive completely.

  You probably have one of these drives to multi format card on your XP machine who caught a lot of drive letters.  If you don't mind not reconfigure your Outlook rules one last time, I suggest assignment drive letter Z (or something else, towards the end of the alphabet) to your external drive.

  • Right-click on the drive letter in the upper pane corresponding to the external drive and select "change drive letter and paths".

  • Select the new letter drive and OK your way out

  This is the result of not not more likely USB ports. You can try to update the drivers of usb device, but if the problem there is not a lot you can do otherwise than to buy an expansion usb card. You can disable usb error reports to stop seeing the error.
