Unfortunately the 160GB drives were decommissioned by Dell a few years ago, after the warranty stock was exhausted. So do to that and their age, I don't see an ability to get one from Dell. The drives actual part number is YF439. If you do a web search for that part number, you will see several 3rd parties that offer the drive.
Sorry I couldn't have better news for you.
Let me know how it goes.
Thanks a ton Chris.
Could you please confirm if YF439 part number would be fine here before i buy refurbished one. i only know the model no and DCM no.
Thanks once again.
