Latitude D510 Boot Problems

Today I had a slight problem with my computer and when I boot my computer, I recieve an error that tells me the following: “Windows could not start because the following file is missing or corrupt: \system32\ntoskrnl.exe Please re-install a copy of the above file” I have booted my computer up using the Window XP Professional disc I recieved with the computer and attempted to run the recovery console, I load up the console and get to the console and where I should have the ability to select a hard drive, there is none to try to repair this problem I then ran a diagnostic test and got the following error: “Error code 1000-0146” I then proceeded to run the following test and got the following error in a series that seemed to never end and the Msg: Block section seemed to repeat indefidently in the number (continuing up one-by-one): “Test Results : Fail Error Code 0F00:0244 Msg: Block 262556887: Uncorrectable data error or media is write protected” Is there anything I can do to recover this information or is the Hard Drive done for? Any help is much appreciated, thank you. Message Edited by RJohnson11 on 05-18-2007 02:37 AM
