Retired, curious, like to walk with my dog and listen to old rock music.

There are a lot of threads on the net about that, the most hilarious is one on a Texas campus site https://wikis.utexas.edu/display/ISO/Breaking+ATA+password+security Then, a bit more serious http://hackaday.com/2011/02/18/hard-drive-password-recovery/ Last I will help you and for free to get rid of that password !!!! First just to grab a copy of MHDD prior to the latest version. Download MHDD 4.5 from here : http://hddguru.com/content/en/software/2005.10.02-MHDD/You will need it because it contain the ATA terminal that you will need for our little experience. Also use the floppy version, if you use the CD ISO you will end up with a "virtual ram drive" when you boot the MHDD and not the real a: assigned to the floppy. Then open your notepad and past the following script : ; rm modul id 42 reset waitnbsy regs = $57 $44 $43 $00 $00 $a0 $8a waitnbsy regs = $00 $02 $00 $00 $0F $E0 $21 waitnbsy checkdrq sectorsto = 42.bin ; End. save the file with a simple name, like "wdpwd" and remove the .txt extension to the file. You should end up with a filename without extension. Save that file to the "Scripts" folder of your MHDD 4.5 Now boot your MHDD copy and detect the locked drive. Mhdd will tell you the drive is locked. Don't worry and issue a .wdpwd or whatever you named the file. You should end up with a file named 42.bin on the disk you used to boot MHDD. If you have booted from cd you will have to copy the file out of it to a floppy, etc ... Post the content here, if you can't figure out where the password is Happy unlocking for free ! Without expensive tools. That experience will also give you an idea about the true importance of vendor-specific ata commands, and in any case will teach you a bit about HDD Have fun! Cheers
