The reason why your external hard drive is lost while installing Windows may be due to flaws in the Windows installation process. Knowing what to do after removing partitions on your Windows hard drive or external storage devices will help you effectively prevent data loss. Here are some suggestions about what you ought to do:

1. You should immediately stop using a partition after it has been deleted or lost from a hard drive or portable storage device. Do not create a new partition or save any data on the device.

2. Some users may be able to recover lost partitions or data using CMD commands. The only use of the commands "list disk" and "select disk #" is to recover a deleted drive letter.
