On a drive there is also the filesystem, which might not be finished with its work. When a program writes to the disk it gets buffered by the OS/filesystem driver first, so that the program can finish, before the data is actually on the disk. So there is no fix, because there is nothing to fix. If you remove the device before the OS tells you you can, you risk missing data or corruption.
