I have no idea how your master.dat could have been deleted,
especially if SQL Server was running (since it is in use).

You can't. The master.dat is like the FAT portion of a drive. It
tells SQL Server where the other files are and whats in them.
Without it, your emerald.dat file is just a bunch of binary
junk. Hopefully you had a dump of your database.
I had a somewhere lengthy post last month on this subject. You
might want to check the archives for it.
