ERD

I'm not sure what you mean with ERD: Emergency Repair Disk, Engineering Review Diagram, Estimating Requirements Document or External Requirements Document? If this is a document you wish to transfer to another computer, you can use pkzip or winzip using the multiple diskette spanning option. If this diskette is to be bootable you will need to determine which files will be on disks 1 or 2.

An ERD can't span floppies. I'll be back in a minute with more info.

An ERD can't span floppies.

When you use the /s command-line switch with the Rdisk.exe tool, the Sam._ and Security._ database files are copied to the %SystemRoot%\Repair folder and to the ERD. If your repair information exceeds the capacity ofa single floppy disk, you may not be able to use the /s command-line switch when you create the ERD.

To create an ERD without copying the Sam._ and Security._ database files, run the Rdisk.exe tool with no command-line switches. Use the Update Repair Info option, and click Yes when you are prompted to create an ERD.

I am assuming you are making an ERD for an NT 4.0 server. I am not confident that you can bridge more than one disk for an ERD. You can, however, Update your Repair Info, which is done prior to making an Emergency Repair Disk in order to catch thelatest system updates and registry information. This "Update" process does place copies of system information into the %systemroot%\Repair directory. These are the files that are placed onto an ERD.

MS Q196603 and Q164471 contain additional information regarding what system files are used from an ERD during an emergency repair and how to modify the Setupdd.sys file. The first does contain, "NOTE: If there is not enough room on the ERD for the file you are replacing, any files other than Setup.log can be deleted from the ERD to make room. This makes the ERD unusable for other repair functions, so keep the original ERD in a safe place. You can also use a second disk containing the file to be replaced and insert it when prompted for the"nt40 repair disk". Read the articles to see if these procedures would assist you.

It still sounds like you need all to be on one disk at some point. Can you copy the ER files onto a network share and create two disks from there? Maybe, but sure better test your Emgergency procedures several times over in the lab first!

Good luck.
