SUMMARY

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.

Older firmware versions in the Quantum LPS240 IDE controller can corrupt data or return incorrect data even though the data on the drive is correct. To determine the kind of disk you are using, run Registry Editor (REGEDT32.EXE) and look at the following: 
   HKEY_LOCAL_MACHINE\hardware\devicemap\atdisk
Under each controller listed, there should be a key for each disk controlled. Under the disk key, the value entry form identifier generally has a string with the make of the drive. The firmware value entry should have the firmware revision for that drive.

Quantum LPS240 should have a firmware revision of 6.x or later. Earlier versions of this drive may need to be returned to the manufacturer since the 6.0 firmware requires a PCB swap on the drive.
