I'm hoping someone can help - my brother passed away suddenly and unexpectedly 2 weeks ago and in the process of sorting through his effects I have come across his Acer Aspire One D250 netbook. I have determined that he kept meticulous records on this machine for tax purposes and carried it with him always. He was obviously guarding it closely because he enabled both the BIOS password and the HDD password. I have been able to clear the BIOS but am now stopped at the HDD password. I came across the description below on this forum and have attempted the first section involving HDD_PW.EXE but to no avail. I have not been able to attempt the second section UNLOCKHD.EXE because I cannot find the UNLOCKHD.EXE program. As you know there is no CD/DVD drive on an Aspire One D250 but I have been able to create a DOS bootable flash drive.
When the machine is turned on and begins POST it goes straight to HARDDISKSECURITY PRIMARY MASTER WDC WD 1600BEVT-(the rest of the hard drive model number)LOCK.
I press Enter and it says:
PLEASE INPUT PASSWORD FOR WDC WD1600BEVT-(the rest of the hard drive model number).
of course I don't have the password so I go through this two more times and then it goes to a choice of
ENTER UNLOCK PASSWORD
CONTINUE SYSTEM RESUME
If I choose ENTER UNLOCK PASSWORD it goes to:
ENTER UNLOCK PASSWORD (KEY:63041378)
which of course I don't have so it goes through this 2 more times and then it says something like:
PASSWORD FAILED
If I choose CONTINUE SYSTEM RESUME I can then boot to the bootable flash drive.
I am able to get into BIOS and there I can confirm it says HDD PASSWORD - SET
Does anyone know where I can get UNLOCKHD.EXE or have some other suggestion other than 'forget it - you will never recover the data on the hard drive even if yo send it into a technician."
Since it provides an UNLOCK KEY there must be an algorithm that can translate that into a password.
