When wanting to eject, message reads the device is currently in use. There is no program using the device. Is it safe to disconnect from computer?

As per the Microsoft Window’s latest update, it is ok to connect & disconnect USB or any other external drive while the PC is on & at working mode but to be on a safer side, it’s always recommended to go for a safe ejection of any external drive or USB drive from the system because not doing so, may lead to some serious data loss situations. So, if you’re habitually ejecting the USB or any other external drive while the PC is on then always have a backup of your data or else be prepared with any data recovery software like Stellar Data Recovery, to recover data in any data loss situation.
