In order to get SeDiv to run, you may need to wind back your system date to the date stamp of sediv.exe.

You will need to access the drive via its TTL RS232 port. To do this, you can use an adapter such as the ones described in this thread:

HDD Unlock Wizard "cannot detect hard disk"
Disk is connected do my Dell Latitude via eSata or via Sata

Are you sure that the drive is locked by an ATA password, and not any other kind of problem?

Is the drive shown with the correct make, model & capacity in the BIOS disk setup screen of the PC?

What are the steps which led to this situation - what changed between the drive being usable, and now?

Or follow the suggestion from Doomer

i'm sure disk is locked by ATA password.
Tomorow i have to buy new drive (Seagate Momentus XT 500GB)
Now i'm sure RMA will be the best for me, but time is money

OK, since you have a plan then I'll stop here. Good luck!
