Is it bad to have a secondaty HDD on same ide cable as CDRW?

[buzzinhornets]

Some told me not install a new secondary harddrive on the same ide cable as my CDRW dirve... is this true? why is it bad to do so?

[khelms]

Are you planning on burning discs from data stored on that secondary hard drive? As I understand it, IDE doesn't allow multiple operations to be going simultaneously like SCSI does, so you couldn't have a read operation to the hard drive and a write operation to the CDRW going at the same time. That might increase your odds of having a buffer underrun when burning a CD.

Is your bus, HDD and CDRW ATA/66 or above? If yes don´t worry! 8)

IDE cannot deal with interleaved commands but this problem only occurs if data transfers are = or above to bus maximum data rate

1 IDE 7200 rpm HDD and 1 CDRW (whatever the speed), even at maximum speed, cannot saturate ATA66 bus data rate. (I still don´t get it why manufacturers produce ATA100/133 drives if HDDs cannot REAL transfer HALF of that rate...)

Conclusion: If you have a good CDRW and HDD don´t worry! I have a 24x SONY CDRW and a Maxtor 20Gb 7200 rpm ATA100 in my IDE2 and I never got problems (even with 2 HDDs tranfering 5 Gb data between them and the CDRW recording at maximum speed from HDD2)

I have heard that you should never mix a hard drive with a cdrw or zip drive. The cdrom can slow the speed of the hard drive.

I don't think it should be a problem. I recently installed a Maxtor 60GB 7200RPM drive as a slave to my Acer 4x4x32 CD-RW and I have no problems burning files from the new drive.
I don't think the drive is slowed down either, it loads a lot faster than my old 17gb 5400RPM.

that's not the cable, look

5400RPM
7200RPM


Of course the 7200 is gonna be faster.
