CDR setup ?



According HP manual setup of my 9110I recommended is that CDwriter and CDrom is both on the same IDE (secondary)and the Harddisk on the Primary IDE , but running Nero I got a message BUFFER UNDERUN and that the problem is that I have both CDdrives on the same IDE , which is not good for read and write process , so which is better both CD drives on the same IDE or each on a different IDE ? Thanks .

it would help a lot if you create an image on the HDD first then burn your cdr rather than direct from cdrom to cdr

Yes, you should have your optical devices on the same channel, and the secondary is best for this purpose. Installing an optical device on the same IDE cable with a hard drive will only slow down the drive, as a device on an IDE cable can only run as fast as the slowest device.

(Note 1: There <i>are</i> newer devices and software that can avoid this limitation ... but this isn't applicable in your current situation.)

(Note 2: An HP drive may not be properly identified by Windows if installed with a hard drive on a primary channel. And you might run into some difficulty upgrading the firmware for the optical drive unless it is the Master on the secondary channel. It is also best that the HP CD-RW temporarily be the only device on the cable during a this kind of upgrade.)

In this scenario, when copying CD-to-CD, you should first copy the data to the hard drive, and then to the CD-RW. You should also turn off any other running processes, in order to avoid buffer-underrun errors, even if you are burning data directly from the drive, and <i>not</i> copying a CD.

Ordinarily, I wouldn't recommend any other burning software than Nero, but for older HP optical drives, you may actually get better results using the software that ships with the drive, which is Easy CD Creator and Direct CD. In my experience, you are much less likely to run into these kind of errors with Direct CD. While the software has it's limitations, older HP writers, without BURN-Proof, simply function better with this burning program.

Remember, you can only have one burning program at a time; Nero and Easy CD Creator don't get along well on the same machine. Whichever you choose, the other must be uninstalled, or you'll have to install some kind of boot-loader to select the program when you start the computer ... and this can get a little complicated.

I'd also suggest that you update the firmware for the drive, if you haven't already.

If you need the installation software for the drive, it can be ordered here:

And here is a link for drivers and downloads ... I don't know what OS you are running, so you'll need to choose for yourself:

<A HREF="" target="_new"></A>

You'll be able to find a link to the latest firmware in this section, which is 1.0c.

Your only other options are to either upgrade the optical drive to one with BURN-Proof, or buy a SCSI drive with a SCSI card. The former, in most respects, is the cheaper solution.
