If you changed the bios battery, or removed the hard drive, the machine will lock you out as it thinks it has been stolen. You will need to contact Acer to get this unlocked

When I turn my computer (aspire one *acer*) on it shows up saying "Harddisk Security" -Primary Master Hitachi HTS543216L9ALock


The hard disk is locked. Since you weren't the one that activated the hdd password it means that the hdd is defective - you will have to replace it and reinstall using an external CD_ROM unit and the recovery disk that you must get from here

I have a aspire one Acer and when I turn it on it says in a blue box, Harddisk Security and under it says Primary Master Hitachi HTS543216L9SLock. What can I do to restore it?


The drive is locked by a BIOS level Hard drive password. You can either contact Acer about a master password or replace the HDD since the password data is stored on the drive itself

Booting my laptop


This is a "security" feature, to allow _only_ the person who knows the password for the encrypted disk-drive to use (and boot from) the unit. There's no way to bypass this security.
