Not at all surprising on that mobo, u really need CentOS on
It still should not be that slow, should it?
that puny thing?
It will be a dhcp/dns server.
It will eventuall be booted from a solid state drive, but doing development on the sata drive.

Is this one of the new 4096-bytes-per-sector Seagate drives? If so, you need to do some research around the 'net to find recommended procedures for aligning partitions. without partitions properly aligned (so that they start on a 4096-byte boundary) things are said to get veeeerrrrrrry sloooooooowwwwwww (though I have no personal experience of it, so I can't speak to HOW slow.)

What do you get from running 'iostat -kx 5' (be sure to wait until the second report) while the formatting is running?

Check your BIOS and set the SATA controller mode to 'NATIVE'. Right now, I'd be willing to bet it's in 'Legacy' or something similar which causes the drives to run in IDE mode, hence why your drive shows up as hdb instead of sdb. This translated legacy mode is horribly slow.

it shouldn't be as slow as it is if its using IDE UltraDMA. but its using IDE PIO, which *is* horribly slow. I wonder if the SATA chipset this board uses is unsupported?

The bios gave me a choice of IDE/RAID, RAID=kernel panic.
Next setting was to disable OnChip IDE Channel1, no increase in speed.
Re-installing.

Well I put the drive in a usb 2.0 enclosure, formatted in just a few seconds.

Why is my SATA drive showing up under /dev/hdb?
That was my hunch:) Config your bios to use AHCI, not compat/ide/or whatever mode it's in now...
Watch your fstab/initrd(if custom) if you boot off this disc. If you are using default lvm/initrd, you'll be ok with a change like this.

I have seen this problem solved by just adding ide0-noprobe ideprobe=0 to the kernel line in the menu.lst of grub at least in in some model of HP desktops. adn a reboot of course.
I have seen performance jump from 10MB/s to 50+MB/s in the hdparm -tT /dev/<devname>
No bios changes/upgrades etc.
YMMV..

I have seen performance jump from 10MB/s to 50+MB/s in the hdparm -tT /dev/<devname>
No bios changes/upgrades etc.
I've got the same experience with HP DC7800 and DC7900's.
CentOS needs these boot options, newer Fedora's don't.

I've never used these options to fix the problem.
I use:
hda=noprobe hdb=noprobe hdc=noprobe etc.
Must be used when installing and added to /boot/grub/grub.conf after installation.

Your motherboard is running in IDE emulation mode and exposing the SATA drives as IDE drives. Many motherboards have this mode to make things 'easier' for certain older O/Ss.
What do you get from running 'iostat -kx 5' (be sure to wait until the second report) while the formatting is running?
This is running faster than during the install ( I have done a yum update now at 2.6.18-164.15.1.el5)

Unfortunatly, there is no option to change this. I will search for a new BIOS for it, but as the system will be running off a flash drive in production I am not in a hurry.

you might just see if you can enable DMA with the hdparm command.
first off...
# hdparm -i /dev/hdb
I only have a IDE cdrom handy on on a centos 5 box (my HD's are all scsi, hardware raid, or fiberchannel), it displays...
# hdparm -i /dev/hda
/dev/hda:
Model=TEAC CD-ROM CD-224E, FwRev=K.9A, SerialNo= Config={ Fixed Removeable DTR<=5Mbs DTR>10Mbs nonMagnetic } RawCHS=0/0/0, TrkSize=0, SectSize=0, ECCbytes=0 BuffType=unknown, BuffSize=0kB, MaxMultSect=0 (maybe): CurCHS=0/0/0, CurSects=0, LBA=yes, LBAsects=0 IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio1 pio2 pio3 pio4 DMA modes: sdma0 sdma1 sdma2 mdma0 mdma1 mdma2 UDMA modes: udma0 udma1 *udma2 AdvancedPM=no
* signifies the current active mode
note the * mode. in my case, its udma2 which is fairly fast (I believe 66MB/sec). a modern hard drive should do udma3 or 4 (100 or 133Mhz).
try...
# hdma -Xudma3 /dev/hdb
.dev/hda: setting xfermode to 100 (UltraDMA mode3)
use at your own risk.

That's exactly the reason your HDD is so slow.
Have seen this before on an 1,5 TB, SATA Samsung HDD (please don't laugh), with IDE Emulation in BIOS. Took me about 2 days to format it and to install the OS on it. As soon as I switched to native SATA in BIOS, everything went smooth: less than 30 mins from start to end.

Your motherboard is running in IDE emulation mode and exposing the SATA drives as IDE drives.
How about this instruction? This MB uses AWARD bios with via CX700M (same as your MB). See the page 3-12 on URL http://www.logicsupply.com/pub/docs/MS-9802Manual.pdf

My options do not include any "SATA" choices. I think I should hold off until I upgrade the BIOS.
