Batch file for Windows System Recovery

[Dusty]

I want to write a batch file to run in Windows System recovery. This batch
file would be used to do a chkdsk of all partitions with the /r parameter.

I can successfully run a batch file that checks all partitions but cannot
figure out how to add the parameter.

I tried for example:

chkdsk d: /r
etc............

chkdsk "d: /r"
etc..........

chkdsk d: "/r"
etc..........

None of those seemed to work.

Thanks
