When your secondary hard drive is a different make or model than the primary hard drive, the filter drivers installed for the primary hard drive may be incompatible with the slave drive. If this is the case, when you attempt to configure the slave, you receive:

There was a problem installing your hardware, Code 28 one of the Filter Drivers installed for this device is invalid.

To workaround this problem:

1. Copy / Paste the following to a NoSlaveFilters.reg file:

REGEDIT4

\[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\\{4D36E967-E325-11CE-BFC1-08002BE10318\}\]
"UpperFilters"=-
"LowerFilters"=-

\[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\\{4D36E967-E325-11CE-BFC1-08002BE10318\}\0000\]
"UpperFilters"=-
"LowerFilters"=-

\[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\\{4D36E967-E325-11CE-BFC1-08002BE10318\}\0001\]
"UpperFilters"=-
"LowerFilters"=-

2. Merge the NoSlaveFilters.reg file with your registry, or run regedit /s NoSlaveFilters.reg.

3. Shutdown and restart Windows XP.

4. Complete the configuration of your subordinate drive.
