Unlocking a Seagate drive by using Master password
A lot of people refer to a utility called ATAPWD. I must say that there is much better alternative: MHDD. This tool is VERY powerful, but be careful with it! Better read the doc...
Anyway. Run it, select your locked drive, then type the following command: ID. It should give you some information about your HDD, and if it is locked then you will see corresponding message.
Now type UNLOCK and press enter.
Program will ask you if you want to use master password or user password. Enter 1 here.
Now it asks you to enter the password. Now please note: you have only 5 tries! You have to re-power the drive after every 5 tries. So, now enter the password. It is one of the following (type exactly as shown here):
- Seagate (and after this word type 25 spaces. Yes, press your space key twenty five times).
- XBOXSCENE
- TEAMASSEMBLY
Last two are good only for xbox drives.
You will have to try all of them. After you enter a password and press Enter, look at the very first line of your monitor (ERR, INDEX, DREQ, BUSY, etc). If 'ERR' is NOT RED, then you did it! You found the password! Now, there is the second step:
Type DISPWD and press enter
Choose master password again by entering "1"
Enter your password once again.
