Sorry to see that there was no response to this thread. Are you still in need of assistance?

Dear writhzinden
Yes i still looking for assistance
thank you

As the messages indicate, the drive is in danger of failure. Loss of SMART data is an early warning. Have you done as it suggests:

Hard disk 1 (301)

There are a number of programs to test the drive, but the one that comes to mind at the moment is HD Tune.

Thanks for the help. and do we know about serial number not found. my hp assistance guide me to install new bios and so i did later on when my laptop restart an error has occur (serial number not found)

I doubt that this error is caused by flashing the BIOS, but anything is possible. However, the logical progression for the process of elimination is to test the drive, before doing anything else.

EDIT: Why did you flash the BIOS in the first place?

I installed new operating system from win7 to vista while on the process i did partition too. In HD tune Health it shows me
(05) reallocated sector count 93 93 140 855 failed (Highlighted with RED Color)
(B8) (unknown attribute) 100 100 97 0 ok (Highlighted with yellow color)

The part that matters is the data for (05). It clearly states that the drive doesn't measure up to minimum on that parameter. The solution should be to replace the drive. Do you have or can borrow a spare drive to test with?

I looking in ebay soon i will buy it. Do we know (solution) about SERIAL NUMBER NOT FOUND error
thanks

It seems to me that we have already covered that question. The only way that I know of to be absolutely certain is to replace the drive and see what happens.
