This chapter contains troubleshooting information for the secure hard drive. If you encounter any of the
following problems when using the secure hard drive, refer to the corresponding answers.
Q: Why could I not enter user mode after I connect the secure hard drive to the computer and input the
correct user password?
A: Input the administrator password or user password when the indicator is red.
Q: What can I do if I forget the user password?
A: You can create a user password. To create a user password, do the following:
1. Enter administrator mode. See "Enter administrator mode" on page 7 for more information.
2. Delete all user passwords. See "Delete the user password(s)" on page 11 for more information.
3. Create a new user password. See "Add a user password in administrator mode" on page 9 for more
information.
Q: What can I do if I forget the administrator password?
A: There is no other way to retrieve the administrator password except a complete reset of the secure hard
drive. After a complete reset, all data will be lost and you need to manually set up the administrator password
and initialize and format the secure hard drive. Then you are able to use the new administrator password. For
more information, see "Completely reset the secure hard drive" on page 12 and "Initialize and format the
secure hard drive after a complete reset" on page 13.
Q: Why does the operating system not recognize the secure hard drive after I completely reset it and enter
user mode?

to "Initialize and format the secure hard drive after a complete reset" on page 13.
Q: Can I initialize and format the secure hard drive with a Windows user account?
A: No, it is a limitation of the Windows operating systems. You should use the Windows administrator
account to initialize and format the secure hard drive.
Q: How do I use the secure hard drive without a password?
A: As a full disk encryption product, the secure hard drive can never be used without a password.
Q: What encryption algorithm is used in this product?
A: The secure hard drive uses the Advanced Encryption Standard (AES) 256-bit algorithm.
Q: Why could I not initialize, partition, or format the secure hard drive?
A: Ensure that you have administrator privileges. You can use only the Windows administrator account to
initialize, partition, or format the secure hard drive in administrator mode.
Q: Why could the operating system not be started from the secure hard drive?
