If your Iomega® disk asks for a password when you try to write to it, you will need to either supply the correct password to unlock the disk or long format the disk.
STEP ONE - Remove the protection by using the password
Use the following steps to remove the write protection from the disk.
You are now ready to write to the disk.
STEP TWO - Long format the disk Warning: A long format will completely erase all of the data on the disk. A long format can take up to twenty minutes to complete. Once the format is complete, you should be able to write to the disk.
