NT ERD - never there when you need it

An up-to-date Emergency Repair Disk is critical when you need to repair a broken NT installation. When you add or remove hardware or make significant changes to your setup you need to update your ERD. This only happens when you explicitly chose the Update Repair Information option. You can bring up the Repair Disk dialog by typing "repair disk" in Start/Help/Index or by typing rdisk in Start/Run. Unless you have explicitly asked for the data to be updated, the information stored on the ERD and the information stored in the repair directory is probably that generated during the initial install. It will not help you 6 months or a year later (or 2 years later). You have added a different harddrive, changed out disk controller, added a partition, removed a partition, .... The ERD is not as important as an up-to-date \winnt\repair directory which has equivalent information. Using the AT scheduler, you can schedule an automatic update of the \winnt\repair files using the command

rdisk /s-

The /s parm tells the repair disk utility to update the erd and repair directory data. The /s- tells the repair disk utility to NOT request a floppy to generate an new ERD but to update the \winnt\repair directory only. Once you have this process automated, you will not need to worry about having a current ERD disk.

OK. OK. You say, what if my harddrive fails and \winnt\repair is GONE. If you are in a network environment, the updated repair data should be copied to a file server for use in this case. If you are on your own, keep pushing those floppies into drive A: and generate updated ERDs.
