[O/T] raptor 10000rpm ide disks

[Neal D. Becker]

I just got a pair of WD raptor disks, which are SATA 10000rpm.  Sweet, right?  
No!  They are connected to Asus A7N8X MB, which has SiI3112 Serial ATA 
(according to dmesg).

hdparm -t shows TERRIBLE slow results.  
/sbin/hdparm /dev/hde

/dev/hde:
 multcount    = 16 (on)
 IO_support   =  0 (default 16-bit)
 unmaskirq    =  0 (off)
 using_dma    =  0 (off)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    =  8 (on)
 geometry     = 4500/255/63, sectors = 72303840, start = 0

OK, now try with DMA turned on.  Locks up machine.  Here's what was logged:

Nov  4 11:30:56 rpppc1 kernel: blk: queue c03c61e8, I/O limit 4095Mb (mask 
0xffffffff)
Nov  4 11:31:01 rpppc1 kernel: hde: dma_intr: status=0x51 { DriveReady 
SeekComplete Error }
Nov  4 11:31:01 rpppc1 kernel: hde: dma_intr: error=0x10 { SectorIdNotFound }, 
LBAsect=1099511642367, high=65536, low=14591, sector=0
Nov  4 11:31:21 rpppc1 kernel: hde: dma_timer_expiry: dma status == 0x21

This is with kernel 2.4.20-20.9.

This is not a Fedora kernel, and also doesn't contain SATA
drivers. (not that the generic ones should crash but...)

    It's not the Raptor drives that are at fault.  I get >60 with hdparm 
-t.  Your kernel doesn't do dma on the sata controller which will give 
you roughly a factor of 10 slower.  Try a newer 2.4 kernel, the libata 
patches, or 2.6.

Fedora doesn't used 2.4.20-9.... wrong list? Anyway, I have the same
board and a maxtor/seagate sata disks (7200 RPM/8 MB both). With the
kernel you're using, I get a meg or two in transfer rate. With the
fedora kernel (or my own) I get just above 50 MB/s.

Yes,  I apoligize for the O/T post (that's why I said it was O/T), but it 
really isn't entirely O/T - because you answered my real question, which is 
whether I should try fedora to see if it fixes the problem.  Thanks.

Yes (just to chime in here)  -- I've also got two of the WD raptor
disks, and am running Fedora.  But mine are hooked up to an ABit MAX3
motherboard, using the Intel 875 chipset as the controller.

In a software RAID 0 config they are very very fast :-)

IIRC, better support for the Silicon Image SATA controller was very
recently added to the 2.6.0-test kernels, so if you're having trouble
with the SI controller, try upgrading to 2.6.0-test9.  

(My experiences with 2.6 recently have been very positive.)

You need ASUS BIOS 1005 or higher for some boards with Nvidia chipsets. 
You may also need current 2.4.x kernel driver bits

LBAsect is bonkers so you may have data corruption, bad memory or possibly
too old a BIOS rev.
