here's a good one.

I am trying to install Linux on a PIII 550 with a Promise UDMA Ultra 66 controller card. I have a second hard drive on the primary IDE controller that I would like to install Linux on. When I boot into the install and come to Disk Druid or any other mechanism for partitioning I see only 1 hard drive hda with partitions hda1 and hda2. I initially had this drive installed in another computer with Linux on it awhile ago however I want to play with some other Linux flavors. Which drive is HDA1. That seems to me to be the the first partition off of the primary ide controller...<br>
or is it? Can anyone help me?<br>
<br>
Thanks,<br>

OK, someone please correct me if I'm wrong, or confirm if I'm right, cos I don't want to give War some advice that will mess his disk up...<br>
<br>
Linux numbers hard disk partitions and devices in the order the appear on the IDE chain. ie, first IDE channel master, first IDE channel slave, then second IDE channel master, second IDE channel slave.<br>
<br>
So, first partition on primary disk on first IDE channel is /dev/hda1. Second partition on primary disk is /dev/hda2. When you move on to the slave disk on the first IDE channel, these are named /dev/hdb1, /dev/hdb2, etc.<br>
<br>
<br>
This means you're right when you say that /dev/hda1 is the first drive on the first controller.<br>
<br>
However, I'm surprised you can't see your second hard disk in Disk Druid. Can you see the second disk if you boot into Windows? (If necessary, format the second hard disk under Windows first. You can always change things back later.)<br>
<br>
Hope this helps.

Your correct with your information,<br>
<br>
hda Primary Master<br>
hdb Primary Slave<br>
hdc Secondary Master<br>
hdd Secondary Slave<br>
<br>
any number after the hd* is the partition number.<br>
If you are connecting the two hard drives and you put a udma card on a pci slot, then your primary interface on the motherboard will be disabled by the bios, maybe the secondary will be disabled as well if the pci controller wants to take over the both channels, so connect both hard drives to your card, put your udma66 on the primary and the other on the secondary, the controller card is backwards compatible with pio modes and udma33 so it will still work, as far as I know anyway.<br>
<br>
Try this anyway. If your cdrom is ide and not udma66 then stick this on the secondary slave, this will make sure you get maximum performace from your udma66 drive and the channel will not be slowed down by a device that is not udma66.<br>

The CD is attached to the secondary controller on the motherboard. MS Fdisk sees both disks. When I had to install RH 5.2 on machines with UDMA cards I had only one option and that was to include:<br>
<br>
linux ide0=0x1440, 0x1436,10 <br>
<br>
on the boot line. I tried this here and had the same result. I will try as you suggest.<br>
<br>
1. I will first fdisk and format the second drive and see if MSWin sees it. I will then set up the second hard drive on the promise controller. I will let you know the outcome.<br>
<br>
Not today though, I am home sick with the crud and am going back to bed. Thanks.

The hard drive sequence is controlled by the jumper settings on the hard drive itself. Set the second drive to slave, cabling doesn't matter. I used Disk druid and it found both drives jusat fine. Sijones is correct with the partitions, hda dor the first drive, then hdb for the second.
