What is “Please insert a disk into removable disk” error?
Computer users are very familiar with USB stick which is portable and provide space to store multimedia files. However, USB disks often bring about trouble when it is damaged or appear unexpected errors. For example, it may become unreadable accidentally. When you try to open it by double clicking drive letter in Windows Explorer, you got error message “Please insert a disk into removable disk” or “There is no disk in drive. Insert a disk and then try again” on a message boxed named “Insert disk”. If you check properties, the USB disk shows 0 bytes. Windows can’t detect the actual size of the flash drive.
Besides, if you check Device Manager the flash drive placed under Disk drives has a different name, which means the controller fails to load manufactures firmware and is booting into fail-safe mode. In Disk Management, the disk has a drive letter but does not have media. That’s because system can’t mount the drive and controller tells Windows that is a Mass Storage device without delivering any information. If you format the disk you might get error message “Windows was unable to complete the format”.
Here is a real case found from Microsoft community:

It shows up in Windows explorer, but when I click on it, it says ‘Please insert a disk into removable disk (G:)’. I disconnected and reconnected the USB drive again, but still get the error. I’m in panic mode, as I can’t access psd and ai files in this disk. Any advice to fix it or recuse my data?”
Causes of “Please insert a disk into removable disk” error

Manufacturers may use poor-quality or generic NAND memory chip which might contain bad sectors. Manufacturers count on controller to record bad sector and repair bad sectors with error correcting code, which won’t be noticed by end users. Memory with poor quality consists of frequent writes to flash drive, but each sector is only good for a limited number of write. This flash controller can’t compensate for high failure rate by adding more error correcting code.
