New CD/DVD drive - 80-wire cable detection failure

New CD/DVD drive - 80-wire cable detection failure

[Nick Warne]

Hi all,

Please CC, not subscribed.

kernel 2.6.23

My DVD/CDrom stopped reading DVD's, so I purchased a new one today.

Old:
Oct 10 21:01:01 linuxamd kernel:     ide0: BM-DMA at 0xd000-0xd007, BIOS 
settings: hda:DMA, hdb:DMA
Oct 10 21:01:01 linuxamd kernel:     ide1: BM-DMA at 0xd008-0xd00f, BIOS 
settings: hdc:DMA, hdd:DMA

Oct 10 21:01:01 linuxamd kernel: hdd: ATAPI 48X DVD-ROM DVD-R CD-R/RW drive, 
2048kB Cache, UDMA(66)
Oct 10 21:01:01 linuxamd kernel: Uniform CD-ROM driver Revision: 3.20

New:
Oct 18 17:32:20 linuxamd kernel:     ide0: BM-DMA at 0xd000-0xd007, BIOS 
settings: hda:DMA, hdb:DMA
Oct 18 17:32:20 linuxamd kernel:     ide1: BM-DMA at 0xd008-0xd00f, BIOS 
settings: hdc:DMA, hdd:DMA

Oct 18 17:32:20 linuxamd kernel: hdd: ATAPI 48X DVD-ROM DVD-R-RAM CD-R/RW 
drive, 2048kB Cache, UDMA(33)
Oct 18 17:32:20 linuxamd kernel: Uniform CD-ROM driver Revision: 3.20

For some reason the new drive produces:

hdd: TSSTcorp CDDVDW SH-S202J, ATAPI CD/DVD-ROM drive
hdd: drive side 80-wire cable detection failed, limiting max speed to UDMA33

I boot with hdd=ide-cd

How to debug this to find out what is going on?

Thanks,

Nick

No help anyone?  Did I buy a taboo drive?  

nick@linuxamd:nick$ /usr/sbin/hdparm -i /dev/hdd

Any help to get this fixed (by me) would be welcome.  I cannot find any 
information on why this happens (or rather why the 'drive side') refuses to 
see 80-wire ide cable.

Did you try another cable?  DId you try using both the old IDE drivers
and the new PATA libata drivers?  What is the hdd=ide-cd supposed to
do?  Do you have a device present as hdc and if not, then why not?
(Hint: ATA spec requires a master before you can have a slave, even
though it frequently does work with just a slave.  Of course cable
select seems even nicer since then the device at the end of an 80 wire
cable is automatically master, and any additional device added to the
middle connector on the cable becomes slave, and you should not connect
a device to the middle connector without one on the end).

Also make sure the right end of the cable is connected to the mainboard,
just in case that matters.

I have (since 2.6.15 at least) hda, hdb, hdc, and hdd.

hda and hdb are mounted at boot.  hdc is not mounted, as I leave that drive 
for backups and mount as needed.

All I done was replace a duff cd/dvd drive (hdd) with a new one.

Ah, so the patch won't help (sorry, I didn't pay enough attention).

Len's advices are worth the try, also please send the output
of hdparm -I /dev/hdd.

Thanks,
Bart

Yes, Len's advice has me wondering now.  Do I have a dodgy cable? I will have 
to change that tomorrow.

But more info.  The old drive played DVD movies etc. OK, but slowly it became 
worse until I couldn't read any one of them 9 times out of 10.  CD play 
back/burning was OK 100% all the time though - so I guessed the dvd laser 
(whatever it does) was dead - hence why I bought a new one. 

The new drive works perfectly, but for the udma33 issue.  If it was the cable, 
why would it read/burn CD OK, but not DVD sometimes on the old drive?

hdparm -I

/dev/hdd:

ATAPI CD-ROM, with removable media
        Model Number:       TSSTcorp CDDVDW SH-S202J
        Serial Number:

        Supported: CD-ROM ATAPI-3 -4 -5 -6 -7
Configuration:
        DRQ response: 50us.
        Packet size: 12 bytes
Capabilities:
        LBA, IORDY(cannot be disabled)
        DMA: mdma0 mdma1 mdma2 udma0 udma1 *udma2 udma3 udma4
             Cycle time: min=120ns recommended=120ns
        PIO: pio0 pio1 pio2 pio3 pio4
             Cycle time: no flow control=383ns  IORDY flow control=120ns

BTW, thanks for help all.

Well older DVD drives often only did udma33 so they would even care if
you had an 80 wire cable or not.  Newer once often require more than
udma33 for full operation.  I got a new drive about a year ago, and
burning dvd+rw at 4x worked great, but all dvd-r at 8x failed.
Eventually I realized I had to change the 40wire cable to an 80 wire,
and all problems disappeared.  The drive works fine in udma4 mode
(whatever speed that is).  My previous DVD-ROM drive had no problems
reading using a 40wire cable.

It should have been hdparm --Istdout (sorry, once again).

[ It is definitevely not my day, or rather trying to debug the problem

There is some confusion on this drive now.  Somebody sent me a link to tech 
specs and that states it only does udma2 mode - but the specs I found state 
it does udma4?

http://downloadcenter.samsung.com/content/UM/200708/20070823084759796_SH-S202J_ENG.pdf

So knowing what these hardware firms are like, maybe it _is_ only udma2?

Thanks,

Nick

I built a new kernel today 2.6.23.1, and looked very closely at kernel 
options.

Setting:

CONFIG_IDEDMA_IVB

did the trick!

hdd: TSSTcorp CDDVDW SH-S202J, ATAPI CD/DVD-ROM drive
hdd: selected mode 0x44
hdd: ATAPI 48X DVD-ROM DVD-R-RAM CD-R/RW drive, 2048kB Cache, UDMA(66)

Thank you all for looking at this non-issue.  Sorry for the noise!!!

Nick

Thanks, the identify block looks quite "interesting".

word 93 is 0x2000

bit 0x4000 is not set despite the fact that ATA spec (>= ATA-5) requires
it to be set (the device claims ATA/ATAPI-3/4/5/6/7 compatiblity, a bit too
optimistic since it looks like the firmware was based on ATA/ATAPI-4 spec)

bit 0x2000 is set which would indicate that the 80-wires cable is
correctly detected by the device

=> the device/firmware pair is a good candidate for ivb_list[]

There seems to be a new firmware (SB01) for this device:
http://www.samsungodd.com/Lib/popup/Download.asp?path=FW_FWDownload&fname=200710011656260232_SH-S202J_%20SB01.exe

It would be useful to know whether it has the same problem...

We want kernel to automatically detect problematic hardware and apply
needed workarounds, _without_ the need for manual user intervention.

[ + CONFIG_IDEDMA_IVB is gone 2.6.24 (but "idex=ata66" is still there) ]

Definitely not the noise, quite the contrary (valuable input). :)

Could you try this patch?

Interesting, I fully understand.

I cannot use this - I haven't used windows at home for a few years, and have 
no way to flash the device up.  It would be interesting though if this does 
make it conform.

Thank you!  This works very well!

Sigh I'd hoped that libata could avoid the word 93 mess but apparently
not. Bartlomiej - I've ported your IVB bits over into libata as a new
horkage type.

According to -
http://www.samsungoms-europe.com/samsung.php?section=product&id=SH-S202&group=multi
this drive only does UDMA2 and PIO4.
