    Before you begin your restore, choose Disk Utility and verify and, if needed, repair your hard drive. You should be able to erase that partition and begin your restoration.

    The "Apple guy" was probably doing a one-pass format, zeroing out the data on the drive. You can do a 7-pass secure erase but that takes days sometimes and isn't necessary if you're keeping the drive.

     

    There's really no need to securely erase your drive if you're not selling the machine. Do you have a version of OS X installed on the drive now? If you have a 2011 or later machine, you can boot holding down the command, option and R keys and boot from Apple servers. From there you can reinstall the OS and then begin your restoration from your Time Machine backup.

     

    Make sense?
