In Disk Management, the disk contains only Unallocated space. I re-plugged the disk, but it stops showing in File Explorer. When the PC booted to Windows again, I got an error message saying, "Windows detected a hard disk problem". Yesterday I connected the external HDD and unlocked it to transfer photos, but there was a system crash. I have a 1TB external hard disk to store family photos and videos and I encrypted it on a Windows 10 computer with BitLocker feature.
