I figured out that my drive not working because it does not read any DVDs (including dell supplied reinstallation CD/DVDs).
I removed the drive and noted the model TS-L632 but not sure it is SATA or IDE. This confusion arised when I looked out for the same model to purchase in Amazon.com and the product says "Toshiba TS-L632 8x DVD±RW DL Notebook IDE Drive (Black)"
Could someone help to figure that the product match my laptop. Thank you!
