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?
