Lacey,
The error you are receiving relating to your HP 9100 series, appears to be related to the burner, NOT MicroStudio. The HP 9100 series is rather old. It was introduced before Windows 2000 (that’s when Windows 98 was king!) It needs specific drivers for newer operating systems
Windows XP does not support all capabilities of that drive; it only supports its reading mode, to use all these drive capabilities you need to install Windows XP specific drivers and perhaps you may have to upgrade the firmware.
HP has reported many compatibility problems with that drive, especially when it comes to using high speed CD-RW media. In fact, HP advices that only 1X-4X media be used. Any other type of media could cause damage to that media.
Now, if you want to continue using this drive, the first thing you should do is make sure that you have installed the latest drivers for your operating system and also check for any firmware upgrade. Once that’s done, we can start solving the rest of your problems.
Remember though, even if and after you get these installations, you still will be able to write no faster than 4X.
Does this drive truly supports CDGs? I don’t know, the specs don’t mention anything about it.
If you want to enjoy CDG writing to the fullest using MicroStudio or any other CDG software package, my suggestion is that you should consider buying a true CDG certified recorder such as the Plextor AND if you want a true guarantee, then you should buy one from MTU
as they test every single drive they sell before it’s shipped to the customer.
If on the other hand you decide to keep your HP, then we will do our best to get it running for you.
By the way, MicroStudio v2.312 works very well under Windows XP.
Best regards,
Jon
