Windows 11
Hello,

I have a Dell Inspiron laptop running Windows 11, version 24H2 (OS build 26100.4652)

I have 4 Western Digital External Hard Drives. I use 1 for my iTunes Music library files , 1 for my Acronis system image backups files and the others for photos, audio files, graphics and other assorted files and folders. Up until yesterday, I only connected 1 external drive at a time, so each drive was always recognized as the 'D' drive. Yesterday, I connected 2 drives at the same time so I could copy/paste and move files and folders from one drive to another. So they were recognized as 'D' and 'E'. Now when I connect the drive with my iTunes music files it is recognized as the 'E' drive and iTunes is searching for the files on a 'D' drive. Same with the Acronis program and a few others. I know that I can go into the programs and change the destination location to 'E', which should solve the problem, but I would rather have things revert to the way they were before; that is, as each drive, when connected alone, be recognized as the 'D' drive. How can I do that? Or is there a different and better solution?

Thank you for your time and help.

Welcome to Eleven Forum.
When a USB drive is connected for the first time it gets assigned the first available letter. When reconnecting a drive Windows tries to assign the same letter it used last time it was connected. Because you were already using D: for the first drive you connected you iTunes drive got reassigned with E:. If you had connected it first it would have got its usual D: and the other drive would be E:.

You can use Disk Management to change the drive letters of your external drive(s). Right-click on a partition to change its letter. Once you have re-assigned D: to your drive Windows should try to use it every time it is re-connected.

    fully 'Windows 11 ready' laptop. Windows 10 C: partition migrated from my old unsupported 'main machine' then upgraded to 11. A test migration ran Insider builds for 2 months. When 11 was released on 5th October 2021 it was re-imaged back to 10 and was offered the upgrade in Windows Update on 20th October. Windows Update offered the 22H2 Feature Update on 20th September 2022. It got the 23H2 Feature Update on 4th November 2023 through Windows Update, 24H2 on 3rd October 2024 through Windows Update by setting the Target Release Version for 24H2, and 25H2 on 30th September 2025 through Windows Update by setting the Target Release Version for 25H2.

    UPDATE - 11 April 2026: due to mechanical deterioration this PC has been retired from active duty. The OS with all software and files has been migrated to my System Seven in 'Other systems' to carry on as my general purpose 'main machine'.
