Copy syntax for command mode from XP HD to Win7 HD

Much appreciated. Tomorrow is another day.

I've looked up the wiki on robo copy and the syntax is above. Is there a preference to those here
who still use the old DOS commands? Perhaps I would make less errors using Robocopy?

Something has gone wrong here and I don't know how to fix it.

I'm showing a Reserved Disk letter at Computer Source drive which I don't understand. My target drive 1Tb drive shows 3/4 of it's space free but my 288 GB media folder transfer gives the error of not enough disk space.

How complicated can transferring one file be? Is there a better way than with these long DOS commands and how to I get rid of the errors? The target drive is fresh. There should be no hidden or reserved info connected with it.

One followup.

I tried something different-- just entered the root directory of both drives and asked to copy the big folder from the source to target drive.

It looks like it's going in ok-- I'll know after some time for the big folder.

But I don't know what I'll have afterwards with Shadow drives or whatevs in MyComputer.

And I don't know why the DOS command with the long string of qualifiers failed to find enough space.

I'm thinking we can mark this solved unless there is comment yet on robocoy as an alternative.
Only thing I think of for the command failing is at the System level it somehow does not see the available partition space.
