I have a number of old external drives in "My Folders" lightroom thinks are still active mostly because the computer has assigned a new drive letter to the same drive several times. I would like to delete these from Lightroom and assign a new letter to the current drive I am using, Any ideas how to remove the old drives?
I just tried this, and it worked. My Lightroom was displaying a drive that I no longer have. There were folders showing on that drive. I highlighted all of those folders, right clicked, and chose to remove them. Once all of the folders were removed to drive disappeared.
This is only advisable if you really no longer have the images contained in those folders!
If they are somewhere, just not at this drive, you should relink them to their present storage location, otherwise you will loose all LR knowledge about them.
If just the drive letter has changed, you should display the highest parent folder on that drive, and relink it to the current letter.
Assigning a letter from the second half of the alphabet, and a different one per drive, makes this need less frequent.
Thanks for the info, all photos are on the drive which I have renamed 'W' I will deleta all photos related to the old drive and reimport the new drive 'W' hopefully this will fix the problem
You will loose your LR work in doing so!
Just update the folder location of the drive, which is not kniwn to LR as W.
If you delete and reimport, you throw all LR records about your images away and create new ones during new import. You start from scratch, reading what is in the image.
I have a little different grasp of what you are doing than I did previously. I understood that you didn't have the drives OR the images. I guess that was a bad assumption on my part. If you have moved those images to another drive or drive letter, the best thing to do is as Cornelia has suggested. Just search for the missing folder, and show Lightroom where the images are now. By doing that, you will retain all of the adjustments that you have made to those files.
After you have found all of the missing folders, and Lightroom isn't looking for images on that old drive anymore, the drive will simply disappear from your folder list.
