Connecting up HDDs and CDs

This has probably been asked before, but I can't seem to figure out the right phrases to use to search the forums for it. I currently have 2 IDE HDDs, and a CD drive. I'm going to be adding an additional CD-RW/DVD combo drive to the system, and was curious about the best way to hook it up.

I currently have 2 IDE HDDs, and a CD drive. I'm going to be adding an additional CD-RW/DVD combo drive to the system, and was curious about the best way to hook it up.
 
I only have 2 IDE channels on my mobo, and currently I have the 2 disks chained together and the CD is on its own.
 
My C drive has WinXP and my applications, the D drive has all my games on.
 
I will also want to do CD-CD copying.
 
So, should I hook up the C drive with the CD on one channel, and the D drive and the CD-RW on the other? Or is there a better solution?
 
Sorry for being dense, but it's been ages since I've had to think about this stuff and can't for the life of me remember the best solution

I would leave both the hard drives on the primary channel, and install the new cdrw/dvd drive as the master on the secondary channel.

In that situation I've always gone for:
 
Primary Master: Main HD
Primary Slave: Second HD
 
Secondary Master: CD-ROM / DVD-ROM
Secondary Slave: CD-RW
 
Currently because of RAID controllers I'm able to hang all the HD's off of the RAID controller and my DVD-ROM & CD-RW each get Master on their own IDE channel.
So like you it's been a while since I've had to think about running four devices off of on-board controllers

Okily dokily, that's what I'll do then. I knew I could count on you guys to point me in the right direction

it doesnt really matter.
it's all gotta go thru the system bus anyway and ide is limited to single duplex.

you could always get an extra ata100 or 133 controller card

I could, but I'm not sure how many PCI ports I have left. I also have a FireWire card I need to bung in for my digi-camcorder.
 
I'll see how I get on. If things start getting bogged down, then I'll consider it.

There is something else. I have
primary master: Maxtor 40gb
primary slave: Maxtor 40gb
 
secondary master: cdrom
secondary slave: cdrw
 
I use nero burning rom and when I try to copy a cd on the fly, nero compains about source and destinarion device beeing on the same cable.
 
I don't use on the fly copying, but is it better to have each cd device on different cables?

In a perfect world, yes, I would have seperate IDE channels for each device, and if I am correct, that's how SerialATA will be. Also, I would recommend you set your cdrw drive to master, and the cdrom as a slave.

SerialATA will only have one device per cable/connection.
The advantage is the size of the connector - only small connector with a few pins (can't remember how many, but it's only about 6) - which means that you can get several SerialATA connectors in the same space as 2 or 4 IDE connectors.
At the moment, they are limited to 133Mb/s, but that's more a limitation of motherboard designs (i.e. the SerialATA controllers are connected via the PCI bus). Second gen SerialATA should transfer at 300Mb/s...can't wait

I would go with tis configuration:
 
Primary 1 [HD1 - With WinXP]
Slave 1 [CD Drive]
 
Primary 2 [CDRW/DVD Drive]
Slave 2 [HD2]
 
That way data transfer between hard disks is faster (different channels), so you could have the Page file on the second.
Faster transfer from HD1 to Cd Buring (different Channels)
More reliable Disk to Disk copying, again because they are on different channels.
 
Anyway thats what i'd do,
 
Oh yeah when playing games that require a CD, faster data transfer, different channels.
And when watching DVD's different channel from Operating system, so probably smoother.
 
Cheers,

Nero complains, but it doesn't cause any trouble for me.

I have four channels (built in HPT controller) so all four devices are masters in their own right.

HD1 (HPT-1)
HD2 (HPT-2)
CD-R
CD-RW

I thought that you should not connect ATAPI devices to RAID controllers... I had read somewhere about the interface being slightly different, and some controllers/optical drives had problems.

Guys I have the same situation as the poster
 
I have 2 ata-100 Hds and 1 dvd-rom drive and cd-rw drive. I do have room to use a ATA-100 promise Ultra100TX2 controller I have if need be but would it be better and faster performance wise to have both HDs on the mobos primary channel since the mobo supports ata-100 and have the dvd-rom drive and cd-rw on the secondary channel? Thx
 
sorry about asking in this thread but I did not want to create a whole new post about the same topic

Don't know about PCI-card contollers for sure, as I have Abit boards with integrated Highpoint (HPT) raid controllers. Here the manual clearly states that you should not connect "non-disk devices" like CD's to the HPT controller.
 
BTW, each controller (normally) has two connectors, and you can, using the master-slave setting, connect two devices to each. As I've understood it: if you have two controllers = you have four connectors = eight IDE channels.
 
Finally, if you only need to connect four devices I've never heard any arguments why you shouldn't connect each device as a master on its own channel. Chaing up two devices means that they compete about the available transfer rate in the channel, and that can not speed things up.
I doubt that you will detect any speed difference depending on which controller or connector you use for a certain device (as long as its not slower than the device), but thats easy enough to test, just switch the connector for a HD between two controllers and measure with HD-tach in between.

Which model HPT is that? Highpoint mention on their website that the HPT372 (which I'm not saying is the one on your board) is backward compatible with all ATA devices. They make no mention of it being limited to disk devices like a couple of their other controllers.

I'm not quite sure whether to believe it or not though...

I have three of 'em:
 
Abit KG7 with HPT 370A
Abit KA7 with HPT 370
Abit BE6 with HPT 366
 
All three manuals contain the recommendation "Thus we suggest you don't connect non-disk devices that use ATA/ATAPI interfaces such as CD-ROM to the HPT3xx connector." The manuals are downloadable on Abits site (at least they used to be) if you don't believe...
 
Besides, the ATAPI interface, which a CD rom uses, is not precisely the same as the ATA 100 or ATA 66 interface. Just compatible.
 
But why on earth would you want to connect a CD to the Highpoint controller in the first place ? You bought the thing to get your HD's up to speed, didn't you ?

Thats not really what I meant.... I was actually referring to Highpoints claim that the HPT372 is backward compatible with all ATA devices. (unlike all their other controllers that I looked at, this one didn't explicitly mention it was limited to disk devices.)

I don't intend to use them for RAID purposes but rather to put all 4 of my IDE devices on seperate channels. I only have one HDD, the other three IDE devices are an LS-120 drive, a DVD-ROM and a CD-RW.

Well, I guess you could buy an PCI - IDE controller card... Likely to be cheaper (?) than the a RAID controller. On the other hand, I guess you could keep those 4 devices you've got just straight on the standard 2 IDE channels, why do you want them as four master devices? You propably need to experiment a little to find the best master/slave combination. I guess I'd start with CD and DVD on one cable, HD and LS-120 on the other (unless you copy DVD's to CD's of course)

It'll be integrated onto the motherboard (An Epox 8K5A2+) so buying an extra controller is probably going to be the more expensive option.
 
The LS-120 is a PIO device (and not a DMA device like the other three) which throws a huge spanner in the works. I want at least that to have it's own channel so it can't screw with anything. The hard drive is less important but that'll be on the RAID controller anyway. I'd rather the CD and DVD-ROM have their own channels too but if that isn't possible I guess they'll just have to share the remaining channel on the regular IDE controller.

Makes sence, altough keep an eye on the HD, that is is performing as fast as it can, thsts one of those things that makes a noticeable speed difference for the user. Try the LS-120 on the HPT controller, if everything works dandy then you have every device on its own controller.
