NEC ND4550A inside enclosure can't run on Inspiron 5150

All hardware mentioned and system info are detailed at the end of this post.

I have Coolmax 5.25" USB/Firewire enclosure which I have so far used only for 2.5 hard drives on my Inspiron 5150. Everything worked beautifully till days ago I put in my new internal NEC ND-4550A DVD burner.

The DVD burner inside the enclosure will show as “Removable Disk” under My Computer. With DVD-RW media loaded when I click on “Removable Disk” icon, it will ask, "“The disk in drive G is not formatted. Do you want to format it now?” When I choose OK, the next message will tell me, “The disk can not be formatted.”. Also with the above setup, the DVD burner cant be recognized by neither Nero or Alcohol 120%. In short, the NEC DVD burner just does not run on Inspiron 5150.

I am using Phoenix BIOS A01 that comes with my Inspiron 5150. I am using the Coolmax enclosure via Fireware interface.

I talked with Inspiron users at Dell forum. The problem does not seem to an old BIOS problem. I have read the BIOS releases notes for Inspiron 5150, but so far the notes did not specifically indicate that higher versions of BIOS would have better support for external peripherals such as DVD burner.

Can anyone kindly advise what might be causing the problem? What should I start investigation with?

Thanks for advising.

====Hardware mentioned in this post====

====System Info====

  • Dell Inspiron 5150
  • BIOS: Phoenix A01
  • 1GB RAM
  • Windows XP Pro SP2
  • Coolmax Enclosure USB/FIREWIRE COMBO 3.5"/5.25"

Your enclosure hold an Cypres chipset, not that compatible with nowdays DVDRW drives. No luck there unfortunately. :sad:
But then you can always try to connect enclosure with/to USB2.

Enclosure has its own “bios” thats why your dell bios has nothing to do with it.

Finally, a better solution might be to buy enclosure equiped with Prolific chipset.

Thanks but I am pretty sure that my enclosure’s chipset is made by Oxford Semiconductor. However I am not sure about
which type of the chipset is. Anyone who’s owned/used Coolmax Enclosure
(CD-510B-COMBO) can advise?

Hmm, the CD-510 “driver” file (dated 04/16/2003) at you linked to gives this info.





[B]CY="Cypress Semiconductor"[/B]
HDCClassName = "Hard disk controllers"
CY_IOSTB.DeviceDesc="Storage Adapter Bridge Module (CY)".

Odd. :rolleyes:

Under systray -> Safely Remove Hardware -> Properties, it is said that it is an Oxford Semiconductor’s chipset. Please see the attachment.

Under Device Manager -> SBP2 IEEE 1394 Devices -> Properties, it is said, “on Texas Instruments OHCI Compliant IEEE 1394 Host Controller”.

Indeed, it looks like your enclosure holds a Oxford chipset… :iagree:
Apparently doesn’t care that much obout its costumers regarding info and drivers.

I also have one of mine 3500’s in a enclosure with Oxford (911) chipset. Read about my experiences here.

Visit Oxford homepage (for “tools” and loader) and try to find out what version of chipset you have. :wink:
