Cannot assign letter from external hard drive

Hello
I have an external hard drive and I am unable to assign a drive letter. I went through the MMC console for disk mgmt, but the only options I get are delete volume or help. Disk Management shows the drive is primary and in good health. (OS: Vista SP1)

Please help, as I have important documents on this drive.

Thank you!
Ahmed

A few things to check.

1 Event Viewer. See if there are errors. They can give clues as to what happened with the reader.
2. check the Device Manager and see if you have devices with a red or yellow marker on them.

This drive worked perfectly up to this point. I tried to restart, unplug the external drive and reconnect it and using a different USB port, but so far nothing has worked.

  • Windows 8 cannot connect to the external hard drive after you have added the drive case.

    Original title: I have my hard drive from my previous PC attached to my new PC with windows 8. My old PC had XP. How to access the external hard drive?

    I had problems with my XP operating system and could not transfer all the files to my new PC. I spoke with Dell who I believe created the problem with software support. I was told to get out the hard drive, buy a hard drive enclosure and get my files from there. I can't find the hard drive.

    Hello

    Thank you for the update.

    Given that the problem occurs when the hard drive is connected to a different USB port or another computer, it is probably related to the connection of the hard disk.

    Method 1: check if the problem occurs in another computer after removing the hard disk enclosure.

    Method 2:

     

    Step 1: Check if the hard drive is detected in Windows Explorer.

    To do this, follow these steps:

    a. connect the hard disk of the computer.

    b. press the Windows key + E to open Windows Explorer.

    c. check if the hard drive is present here.

    Step 2: Check if the hard drive is detected in disk management.

    To do this, follow these steps:

    a. on the desktop, press the Windows key + X , and then select disk management.

    b. check if the hard drive is listed there.

    Contact the manufacturer of the hard drive and hard drive enclosure for assistance.

  • How can I transfer images from external hard drive with the gateway settings to new computer?

    I used to use Adobe Bridge on a computer that no longer works. My computer tech then made the hard drive of this computer on an external hard drive. Now I want to transfer all those images with all the settings, I applied them to my new computer. My new computer is a PC with Windows 7 and I run Adobe Creative Cloud on it.

    Thanks for your reply. Where the xmp file?

    It depends on your preferences settings. By default, Bridge is set to store metadata in an XMP file. This is the file that has the same name as the original, but it only use the extension ".xmp" instead of Raw file extension.

    Bridge stores this file in the same folder as the original. If you use Bridge to move the files to another location it selects automatically the xmp files to travel with her.

    If you use the view menu / show hidden files, you will see what Curt meant by XMP are hidden files, all have a document icon.

    If you converted to DNG RAW format this data is written to the file itself, as is the case with other types of files such as jpeg and tiff, that can be managed by the cab.

    You should be able to copy the whole folder to your new system or bridge to the old disk, select the file in the content panel and the use of the Control Panel folder to navigate to the new location and use drag and drop
