If you ever clone sql server from other server. you might end up with this above error when you run any sql server agent jobs. Because name of the current sql server and oringally installed sql server is totally different.

Robocopy files to another Drive

Robocopy files to another Drive with estimated time to complete
If you ever plan to move the sql data(mdf) or log file (LDF) to another drive then try to use robocopy is much better than windows file copying and takes less time.

In that command prompt e.g:
F:\Robocopy  "E:\SQLData" "F:\SQLData" mydb.mdf mydb.mdf /ETA

E:\Robocopy  "D:\SQLLogs" "G:\SQLLogs" mydb_log.ldf mydb_log /ETA
