SUMMARY

When you add multiple SCSI adapters with Windows NT, it is possible to give disk 0 a drive letter other than C:.

This is because Windows NT gives the drive letters according to the order that the SCSI device driver is loaded, which is determined by the tag order of that driver. By changing the tag order of that driver, you can change the order of which driver is loaded.

Step-by-Step Procedure

WARNING: Using Registry Editor incorrectly can cause serious, system- wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.
  1. Run Registry Editor (Regedt32.exe).
  2. From the HKEY_LOCAL_MACHINE subtree, go to the following key:

    \System\CurrentControlSet\Services\%adapternam


    You will see a parameter called TAG on the right-hand side of the split screen.
  3. Select the TAG value, and press ENTER to open the DWORD editor.
  4. Reset the values in the fields. The lowest number should be the adapter you want to have initialized first.
  5. Shut down and restart Windows NT.
  6. Run Disk Administrator to verify changes were made correctly.
