Hello and thank you for your question. Please let me know if you still require assistance and I would be happy to help you.
It sometimes takes awhile depending on how many experts are available. Do you know how the HDD became locked?
Okay. Please understand we are very cautious when it comes to assisting in unlocking BIOS or HDD passwords since we have no way to verify the owner. I have two options for you. The first is to check this LINK for a utility that should work for you. In case this fails, you will need to contact Toshiba to have them assist you. They will require owner verification before they proceed.
