Re: 'ERROR CODE:0141, MSG ERROR CODE: 2000-0141, HARD DRIVE:- NO DRIVE DETECTED'
I did a bit of research on this and i find this system has been tested with 500 GB 5400 RPM Sata II HDD from Toshiba and Samsung.So ideally 500 GB HDD 5400 RPM Sata II should work on this system.
So in your case you may try updating the BIOS and see if that helps.(However updating BIOS sometimes may cause motherboard failure.Hope you are aware of it and if the system is out of warranty Dell will not be able to replace motherboard free of charge, in case of motherboard failure while updating BIOS).
If you want to update BIOS, use the link below to download the latest BIOS version A17 for your system.
