Windows XP
Optical drives
never require a driver when used in any Windows os from Win95 up. Windows XP and Windows Vista both provide native support that allows an optical drive to read a data or music disk and to burn a cd-r disk. No support for playing dvd disks, avi or mpeg video files, or for burning cd-rw or dvd disks. For those tasks, compatible 3rd. party recording & dvd decoding software is required. Any modern optical drive is plug and play in all Windows OS’s beginning with Windows 95.
If your problem is non-detection, ie: drive is not listed in My Computer, there’s 4 different methods to fix this problem….
take your choice from below:
Fix #1: Please read post #24 in this thread: http://forums.driverguide.com/showth…t=21669&page=4
It contains manual instructions on the delete the upper and lower filters fix, that will solve the problem.
If only one of the two filters are listed, just proceed with deleting the one only, then resume.
Alternately, you can use any of the other fixes listed below: (Fix #3 is the easiest of all to use)
Fix #2:
Also, there is a STICKY posted in this forum that contains a file from Microsoft and instructions that will do this registry edit automatically instead of having to do it manually.
You can find this thread here: http://forums.driverguide.com/showthread.php?t=30011
Fix #3:
And here’s another method (CdGone.zip) that will do this procedure automatically for you if you’re afraid to edit the registry manually.
Fix #4:
Alternately, download and install the DVD fix from this Web site:http://www.dougknox.com/xp/scripts/xp_cd_dvd_fix.vbs
Download the file and save it to Desktop. Open an “admin” Command Prompt
Note: You must copy and paste (into Notepad) the text on the Doug Knox page then save it as xp_cd_dvd_fix.vbs
then run the .vbs file by typing the following at the console window:
wscript.exe “%userprofile%\desktop\xp_cd_dvd_fix.vbs”
Now…. after performing this fix, don’t reboot yet. Next, (in Device Manager), uninstall all optical drives listed
(if none are listed, continue with next step)…
Reboot the pc or “scan for hardware changes”. Your drive(s) should now be visible in My Computer and work properly.
If the drive still fails to work properly after performing any of these fixes, it most likely will need to be replaced.
Also, for optical drive problems in Windows Vista, read this HP web page.
Even though it’s for HP/Compaq machines, the same principals applies to all modern IDE optical drives regardless of brand.
If your drive stopped working after installing an Adobe product, please read this thread. Note: about 2/3rds. down the page
is a video that shows how to perform the “delete upper and lower filters fix”.
This is a multi-page thread dealing with issues of the optical drive and problems encountered in Windows XP and Vista.
It covers a lot of issues and the most common causes and solutions. Click here to read the thread.
You can get instructions for performing this fix from Microsoft at this page [in Windows XP] and from this page. [in Windows 2000]
Also, check the USB port(s) in Device Manager to insure it’s working.

In this Zimbra Administrator’s PowerTip, we’ll discuss how to move your instance of Zimbra to another machine. It applies to all version of Zimbra.

Administrator’s PowerTip

Introduction
Either you, or someone you know has been there. Almost out of Disk space, RAM is topped out, and the CPU is constantly running above 80%. It’s time to upgrade the hardware. But how easy and safe is it to move the Zimbra server instance? Well, it’s easier than you might think.
In this Zimbra Administrator’s PowerTip, we’ll discuss how to migrate your Zimbra server to another Machine or OS. The one big caveat is that both instances of Zimbra MUST be running the same version. So if your old server is running 4.5.5, then you’ll need to install 4.5.5 on your new server. This wouldn’t be the time to upgrade your ZCS version.
Part 1 : Backing Up
Step by Step:
- As zimbra: zmcontrol stop
- As root: ps aux | grep zimbra (make sure everything’s stopped)
- Mount external disc to location of your choice. ex: /mnt/migration
- As root: rsync -avH /opt/zimbra /mnt/migration (this may take a while)
Zimbra Network Edition contains a backup feature, and although it’s useful, we won’t be using it in this tip.
We have an external Hard Disc mounted to /mnt/migration. When rsync’ed, this is now your live copy (although it’s not live), and you should always have a backup of your live data. So, you might want to rsync again to another location to be safe.
Once you’ve rsync’ed all your data, umount the external drive, and put it somewhere safe.
Part 2 : Meet Your New Server
Step by Step:
- Install Newer (supported) Operating System
- Turn off older ZCS Server
- Set up newer ZCS Server’s Network/Hostname is it was on the older server
The only thing that really matters on your new server, is whether or not meets Zimbra’s server Hardware and the Operating System requirements.
It’s also very important that you have resolved any dependency issues. The ZCS installer for your newer OS should check for these.
Setup the newer server with the old server’s networking attributes. Make sure your older server is offline.
If changing the hostname, please see this wiki article: Set zmhostname
Part 3 : Create a “dummy” Install Then Remove It
Step by Step:
- Download the version of ZCS (ie 4.5.5 or 4.0) for the new OS you have
- As Root: Run the installer with the -s option: ./install.sh -s
- As Root: Remove the dummy install: rm -rf /opt/zimbra
The goal of this step is to get the rpm/dpkg databases correct. When you download ZCS, make sure it’s for your newer OS, and the SAME version of ZCS that’s rsync’ed.
Run the installer with the -s option. This tells the installer to only install the software, and not to configure the installation.
Once the installer has completed, delete it by rm -rf /opt/zimbra. This wipes any dummy data you have in that location.
Part 4 : Mount Your Backup HD, rsync, and Install
Step by Step:
- Mount external Hard drive
- As Root: rsync your backup to the new location: rsync -avH /mnt/migration/zimbra /opt/
- Unmount external Hard drive and keep it safe
- As Root: run zmfixperms located in /opt/zimbra/libexec
- As Root: rerun the installer without the -s option
Connect and mount your external hard drive. Then, rsync the backed up data to its new location (rsync -avH /mnt/migration/zimbra /opt).
Connect and mount your external hard drive. Then, rsync the backed up data to its new location (rsync -avH /mnt/migration/zimbra /opt).
Unmount your backed up copy, and keep it in a safe place.
Now that our data is all in place, we need to fix some permissions. Go into the /opt/zimbra/libexec directory and run zmfixperms. This helps insure that all the files are owned correctly.
Once that has completed, re run the installer that you downloaded. It will detect ZCS already installed, and ask if you want to upgrade. Select Yes.
