harddisk not readable and not booting

Question

I have installed ubuntu 10.10 on my HP Pavilion dv-7 4285dx laptop. When I try to perform a smart test on the hard drive, it informs me of several bad sectors and shows message like this:

Current Pending Sector Count
Number of Sectors Waiting to be Remapped.If the sector waiting to be remapped is subsequently written or read successfully, this value should be decreased and the sector remapped. Read Errors on the Sector will not remap the Sector, it will only be remapped on a failed write attempt.

Answer 1

Your hard drive is having significant hardware issues. It is probably time to get a new drive, even if the sectors are remapped.
