External Case for DVD-R/RW doesn't show atapi driver

Posted on 2004-09-10

Hey guys,

I have a question relating to my external case.  After numerous times of trying to write to a DVD, I keep getting "scsi command aborted".  I looked in the log from Nero and this is what I got.


Windows XP 5.1
WinAspi: File 'Wnaspi32.dll': Ver=4.71 (0001), size=45056 bytes, created 8/14/2002 3:03:36 PM
ahead WinASPI: File 'C:\Program Files\Ahead\nero\Wnaspi32.dll': Ver=, size=160016 bytes, created 7/22/2004 5:33:44 PM
Nero version: (Nero Express)
Recorder:             <LITE-ON DVDRW SOHW-1213S>Version: TS0D - HA 2 TA 0 -
 Adapter driver:      <>                        HA 2
 Drive buffer  :      2048kB
 Bus Type      :      default (0) -> ATAPI, detected: ?
CD-ROM:               <LITE-ON  COMBO SOHC-5232K>Version: NK0A - HA 1 TA 0 -
 Adapter driver:      <atapi>                   HA 1

=== Scsi-Device-Map ===
DiskPeripheral       : SAMSUNG SP1604N                  atapi Port 0 ID 0  DMA: On
DiskPeripheral       : WDC WD600AB-32BVA0               atapi Port 0 ID 1  DMA: On
CdRomPeripheral      : LITE-ON COMBO SOHC-5232K         atapi Port 1 ID 0  DMA: On

=== CDRom-Device-Map ===


You will notice under the adapter driver for the DVD, there is no adapter driver listed, just <>.  Also under the CDRom Device-Map, the Drive isn't listed.  The DVD-R is seen under "My Computer" with a drive letter, and the external enclosure that it is in has worked with other devices in it (hard drives, cd-rw's).  I am going to try to get a usb cable that is 2.0 certified but I don't think that is it.  The Chipset for my external enclosure is from Oxford Semiconductors (uf922ds) if that is any help.  I tried uninstalling and reinstalling the drivers for the DVD drive also, and still no luck.   Any suggestions to get my enclosure listed under CDRom Device Map and have an ATAPI driver associated? Thanks alot!

Hmmm can I just ask something, when your using Nero does it support your DVD drive.  Many versions of Nero are locked to a specific drive.

You will need to check this from within Nero when you select the drives to write to, otherwise it will abort the writing process.

You could try deinstalling Nero and re installing it again to see if it then picks up on your DVD drive.

Thanks pj for the prompt response.  

Yes, I am using the Nero that specifically came with the DVD.  I also used the "General Clean Tool" after uninstalling all of Nero's programs.  I believe it has to do with my external case and dvd being recognized.  The drive is supposedly for internal use and then I put it in a external case.  I'll try it on another computer to see if it is recognized but I'm still curious if anyone knows how to get the atapi driver associated with the external drive (I guess I can also try another drive in the case and look at the log file also).


PS- it is just kind of wierd that the drive is found and has a drive letter but just not the atapi driver.  Also wondering how I can see if the atapi driver is associated with the drive without having to look at logs after the burning attempt.

Its a a USB connection from the case I take it!

I seem to remember and I am saying that because its been a while since I have seen one of them!  I presume there was some software that came with the Case?  

Or there should be for you to be able to use it through the USB, I may be wrong here by presuming your using a USB caddy.  If you are then which one are you using?

Yes it is a USB 2.0 connection.  There is also a firewire connection which I should try to see if it makes a difference.  I also think there was software that came with the case but if my memory serves me correctly, it was for windows98se only, and it was suggested to use XP's OS drivers for XP.  This link is where I got the drive from.  I never heard of the manufacturer before, but I will track down info relating to the drive to see if I can find some drivers.

the atapi driver bundled with the nero is only for the ide interface. try using the software for the external case or check with the manufacturers website

Hmmmmmm interesting they only had windows 98 drivers?

That is a bit behind the times isn't it!   You know what I would do?    I would throw it away and get one that has XP drivers, i don't think your going to get drivers for this.  If it has a PCB board inside the caddy then your screwed.

Just a suggestion it may not be suitable for you but thats honestly what i would do and stop wasting my time with it!

Anyway all said and done with it I wish you the very best of luck and I hope that if you don't decide to get one thats going to work that you manage to resolve the issue.

Thanks pj for your assistance.

After extensive testing and creation of numerous coasters, it seems to be specific to the USB connection on my crappy Gigabyte motherboard (7n400 proII).  Not the connectivity to the internal drive in a external casing, not the software nor outdated drivers or firmware.  After connecting it via FireWire, there were no more problems.  I tried my DVD writer on 2 other computer connected via USB and with no problems (tested it with Norton Ghost, Nero Express and InCD).  On the computer with the Gigabyte, I even tried updating to XP Service Pack 2 (shows how desperate) to update the USB drivers as I could not find newer drivers on the net.  Also tried forcing the ASPI.  The reason why the DVD drive was not showing up in my Nero log is because after the scsi command aborted error, it would take at least 5 minutes for the drive to stop.  After waiting impatiently, I would manually turn the drive off and as a result the log would not list the drive under the Device Map.  With "Intel" manufactured usb connections on other computers, the drive worked fine- with the "Standard Enhanced" listed on the Gigabyte computer, it did not.  Next I'll try using Intels drivers if possible.  Thanks for all of your help.


ps-  I hate throwing away something you pay for!   :-)

-----Update to the reason why "scsi command aborted"-----

It seems that the error was not solely based on the above statement but also based on the media I was using.  After I purchased and tested out 8x's +R media and it worked out great.  Guess it is just trial and error sometimes.
