I have a customer with an IBM Lenovo ThinkCentre 58e model 7259 with XP Pro SP3. We had a motherboard problem that couldn't be fixed so sent it back for warranty replacement. Got the new computer last Saturday (they replaced the whole computer). Installed everything just fine. Got system stabilized and then came back on Tuesday to burn recovery CDs. The DVD was now missing. I tried system restore to the day I set everything up...still no drive. So I went into registry and deleted the upper and lower filter in the current control set of the class on the local machine based on a post I found elsewhere on Experts Exchange. I restarted the computer and the DVD came back for a few minutes(less than 5). I went to burn the recovery CDs and it had reverted to a CD but was still visible. After going thru various attempts to get the drive to show up correctly, including re-seeding the drive, cleaning the connections, etc. decided to exchange the computer but pull the hard drive and put it in the new computer because I didn't want to have to reinstall everything for a 4th time and the place we got the computer decided the laser must have gone out on the DVD. We put the hard drive in the new computer and initially it saw the drive as a DVD but within 5 minutes, it is now showing as a CD.
I don't think it's the drive but I don't want to reimage and reinstall again. I have to have a working DVD/RW to move forward and I'm not sure what to do. I'm thinking I need to edit the registry again but I don't know to what. I will buy an extrernal DVD/RW if necessary but the customer isn't going to be happy and I will be out even more money & time. Any suggestions?
