HDD/DVDROM conflict

[tvarad]

I have a Maxtor ATA133 80GB and a Shuttle SDVD-101 DVDROM that I am trying to connect on the same IDE channel. I have set the detection to auto in BIOS but when the BIOS boots up, it delays it's detection of the hard drive (with a "press F4 to skip" message). It then boots up normally and both drives are detected but when I work up the hard drive (e.g. by using Mehul's Backup to back up some files), it hangs and then crashes.

If I remove the DVDROM, the detection is instant and the program works fine. So it's obviously a conflict between the high speed hard drive and the DVD-ROM. Any ideas on how to resolve it?

Is one of the drives set as master and the other set as slave? Try putting the DVD-ROM on the secondary channel as the master. Hope this helps.

Yes, it is set as master and slave. I decided to put both my hard drives which are ATA100 compliant on one IDE channel as master and slave and have the DVDROM on the second channel and that seems to have fixed the problem.

The DVDROM used to work fine with an older UDMA33 drive as slave and master so there is obviously a conflict with the newer faster bus drives.

You might try "cable select" and see if that works if having them on the same channel becomes a must

A continuation of my problem: I have now connected my Maxtor 7200rpm 80Gb hard drive and Seagate Barracuda IV 7200rpm 80Gb hard drive on the primary IDE channel in master-slave mode. That seems to work fine. However, when I connect up just my DVDROM (Shuttle DVD-101 10X) on the secondary IDE channel in either Master or Cable Select mode, I have a bootup delay of over 2 minutes. This delay is somewhat less if I connect it in Slave mode. If I disconnect the DVD-ROM, bootup is fine.

Thx.

Maybe flash the firmware on the DVD-rom if that's possible? During the delay, does the DVD activity light come on? Maybe there's a BIOS update for your motherboard?

The last thing I can think of trying is to manually input the drive info into the BIOS instead of using the auto-detect feature. I haven't had the chance to play with the Maxtor ATA133 drives yet so I'm not sure what issues they would cause with slower devices.

Tried to flash new firmare but it just hangs. And there is no DVDROM listed in the types under the secondary master. I tried CDROM but that didnt work.
