How to create a batch file to repair and start corrupted mongoDB in windows?

Question

I am unable to start my mongoDB after an unclean system shutdown. There is a mongod.lock with a size of 1 KB. I want to delete this file and then repair the mongoDB. I deleted the file and tried the command

mongod --dbpath "%ProgramData%\mongodb\data\db" --repair

But I am getting an error message...

I STORAGE [initandlisten] exception in initAndListen: 72 Requested option conflicts with current storage engine option for directoryPerDB; you requested false but the current server storage is already set to true and cannot be changed, terminating.....

Please assist...

Try to add --directoryperDB like this:

mongod --dbpath "%ProgramData%\mongodb\data\db" --directoryPerDB
