  • Where and how can I reinstall the external hard drive to the new HD to the computer?

    Original title: HD crashed.

    I want to thank the person who answered my question about the HD crashed I saved all my data and window xp. My next question is, how and where can I reinstall external hard drive for the new HD to the computer? Should I send it to drive c or where? I'm not strong when it comes to computers. I know just enough to get me in trouble. Thank you.

    Hello!

    You will need to use a full copy of Windows XP.  Should be a sticker with the product key on the side of your desk or below if it is a laptop.

    Once you have this drive, you can reinstall Windows XP.  After you have installed all the software and drivers, you will be able to transfer all your data to the new HARD drive.

    If you don't have a copy of Windows XP, you can probably get a copy of the recovery from the manufacturing of computer media.  Just to provide the model and serial number and they should sent it.

  • reloading the files of the external hard drive to the new computer laptop

    I'm trying to reloaded files etc. from an external hard drive to my laptop. I took the files of my old office that was on is way out, so just in case I lost them all I copied them. I tried setting up my external hard drive and transfer just a couple of files just to see if it would work. I sent them to my desktop from my laptop and they also went to my documents, but once the hard drive is disconnected files will not open. I do not know what I'm dong wrong as I am not very computor spirit, so that the answers would be useful in silly English thank you. Sorry to be so long-winded.

    Hello @shedeval

    I understand that you have copied your files on an external drive from your old computer.

    You tried to copy the files to the new computer, but when you disconnect the external hard drive the files are no longer accessible.

    I think that you have created or copied a shortcut to the new computer and not the actual files.  When you're logged out outside the new computer had more disk access to open files.

    I would like to redo the copy and when you finished externally, log out and then try again.

    Good luck!

    I currently store my pictures on and an external hard drive.  Lightroom 6 was not able to find the picture momentarily files.  I inserted an external Flash DRIVE after removing the hard drive and the computer renamed the stick with the same drive letter that has been designated by Lightroom to store my photos.  I could go into my Windows 10 and reset the player to the letter that Lightroom has given at the beginning of the external hard drive.   However, I know this can happen again, if I connect any stick USD or another device, while the external hard drive is not connected to my laptop.   I found the information that I can do the new designation of the final drive by choosing a letter it is 1/2 way or higher in the alphabet.   I would like to turn an external hard drive on a strong letter, warns we hope this previous problem.   My question is, if I already have a lot of pictures on this external hardrive with the designation of the current drive, how it becomes a higher letter and have 6 Lightroom recognizes files, now under the new designation of drive letter without having to go to each photo individually and manually force Lightroom 6 find each photo.  It would take more time than I'd like to lose.  Is there a way to get just 6 Lightroom to recognize the new disk designation has changed and is able to find all of the existing files?

    I have read the ADOBE LightRoom 6 manual and seem not to be able to find anything on how to do it.

    Any help would be welcome.

    Thank you!

    So in Windows, you can select a drive like q letter (or any other letter you want only towards the end of the alphabet)

    Then in Lightroom, you can reconnect to the photos on q: the following instructions (see specifically 4 Figure and related text)

    Hi Robert!

    Looks like you want to make a backup during import. If this is the case, you can designate a different location for a second copy when importing.

    1. Check the mark a second copy of box in the management of the files Panel and choose your external drive in the menu drop-down
    2. Then you set regular destination of Lightroom in the Destination panel.

    However, if you mean that you want in the foreground images in Lightroom, but have them physically located on an external drive, then all you need to do is choose this drive in the Destination panel. Lightroom Catalog can be on a different drive.

    I find it useful, however, to use the automatic backup in file management Panel in case.
