My apologies for the length but am unsure of specific diagnostic data needed for trouble shooting responses. From perusing the threads, there are a lot of competent people who are really sharp in these matters. If additional info/diagnostics are needed, let me know. I've researched a lot of Liteon/Microsoft/Intel et al web sites but haven't found the resolution, as yet.
I've posted the following on other boards with one response that has provided some assistance but am still plagued and mystified by the problem. The following was my original post. Current status follows the initial post.
:sad: PROBLEM:
Disappearing Drives
(sometimes hours after startup; sometimes minutes after; Reboot resets drives; Reads previously burned CD-RW info OK):
Internal: LITE-ON LTR-24102B Firmware:5S54 Driver:cdrom.sys (5.1.2600.1106 (xpsp1.020828-1920)
Internal: LITEON_DVD-ROM_LTD163 Firmware:GH5E
Driver: cdrom.sys (5.1.2600.1106 (xpsp1.020828-1920)
(Afraid to flash updated firmware until issue(s) are resolved)
When Intel Application Accelerator is installed, Event Viewer shows Idechndr is not responding within timeout and the error cycles every 5 seconds slowing system response until it shows both the devices (CD-RW and DVD) disappearing from system.
Tried using Intel Accelerator to slow the drive speeds down to PIO (per Intel guidance) w/o success. Intel Accelerator initially shows the CD-RW as Master on Secondary IDE Channel and DVD as Slave. Hard Drive is shown as Master on Primary and Empty on Primary Slave until devices disappear.
Uninstalled Intel Accelerator and now the event viewer shows error of Device\Ide\IdePort1 and then IdePort0 failing to respond within timeout and they disappear from system.
Have disabled Imapi but have noticed that Event Viewer shows sending a start Imapi CD-Burning COM signal, then it show Imapi starting then stopping just before each Error of either Idechndr or atapi Error starting up

The above was posted on dvdrbase.com and the thread's administrator offered it may be an Intel Mobo/chip/Intel Application Accelerator issue (seems there are Intel issues with similar problems) Unfortunately, resetting the bus to a standard Dual Channel PCI IDE Controller and standard windows drivers only changed the Errors and the drives continue to 'disappear'. :sad: :evil: At least I was able to flash and upgrade the drives' firmware to their current versions but the issues continue. For his responses and my current circumstance/pending next steps, see: http://www.dvdrbase.com/showthread.php?t=36131
Any assistance and/or insight into possible causes/solutions the members of this board might offer would be greatly appreciated.
