It could be the HD failing, the onboard controller failing (meaning the motherboard, or more importantly the laptop is toast), or it might simply be that the HD connection to the controller just needs to be reseated. The first thing to try is the HD test built into the BIOS. It should give a clearer idea of what is actually happening to the LT.

Sounds like the disk drive has errors probably caused by a mechanical failure. You had a number of previous failures before this one and the disk is most likely unusable.
A local computer shop (not a big box store) MIGHT be able to recover your data but not your programs.
Hope this helps. I would appreciate your feed back.
HI rogerspie200 , actually problem is related to your Hard Disk Drive Bro not to BIOS and other hardware problem so please first of all check your Laptop Hard disk drive for whether it is working or not , if it is working then just format your pc
Hi I have the same problem - when I turn on my compaq nc 6230 it says "1781 Disk 1failure ", I click enter button and it's starts to boot windows xp and works good without any poblems. I took the HDD out and install into different nc6230 and it works good and no any erro "1781 Disk 1 failure" at all - so it's NOT an HDD problem ! Can somebody help to troubleshoot ! Thanks.
