There's no such thing with PCI/PCIe anymore. Each device driver needs to register interrupt handling code, and these are chained together.

First check your power settings. Do you have your laptops set to power off drives to save power? I have only seen this once and it was because the drive was powered off to save power and when it was the only way to get it back in that laptop was to pull and insert drive. ________________________________________ From: Ben Scott [mailvor...@gmail.com] Sent: Wednesday, September 29, 2010 9:24 PM To: NT System Admin Issues Subject: Re: Strange disappearing DVD Drive.

I just don't know how to troubleshoot that though. For some things, one thing you can do is use DEVCON to restart the device node. However, since the optical drive is attached via SATA, that will likely disrupt the hard disk's SATA connection as well. Windows gets very upset when you take away the hard drive. I suppose you could try it anyway, if you've got good backups. :) Does the parent device node in Device Management also disappear or otherwise act funny when the trouble happens? Again, view Dev Mgmt by connection (rather than the default of by type). Anything in the Event Viewer log? Is there anything you can do to induce the problem? Any pattern to when or how often it occurs? -- Ben ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe ntsysadmin
