Remove Write-protection from a disk

My Disk is write-protected. How can I remove its write-protection so I can copy the data to my C drive.
I am using a Windows 7 PC with an internal blu ray DVD drive.
Any input will be appreciated.

How is it write protected?

...  BIOS password-protected hard drive?
...  company PC with no-write policy on the C: drive?
...  drive properties set to Read-Only?


If the first, you MUST know the password;
if the second, you need to see your administrator to see if they will make an exception to allow writes;
If the third, and your account has administrative privileges, you can simply change it on the Security tab of the Properties page for the drive.

If something else, describe it here.

If you're copying *from* a write-protected disk, that should not stop you.  Write protection doesn't stop reading, which is what happens when you copy from the disk.

I beliee I've heard of copying software that tries to change the timestamp on a file.  That won't work.  But a simple utility like the drag-and-drop in Windows Explorer or the command prompt "xcopy" utility shouldn't have a problem.

But, it depends on the type of disk and exactly how copy protection is in effect.

Sorry, I thought I had misleaded everyone.
Typo... "My Disk" > "My Disc"
Actually I just find that it is a blu ray disc.
I can still copy some of the data from the disc, but most of them are burnt with write-protection.
I even tried to create a new image of this disc by other kind of software (e.g Nero) but happened with the same error and cannot be copied over:

"The disk is write-protected.
 Remove the write-protection or use another disk."

Yes, BluRay discs have copy protection.    While there are indeed programs designed to circumvent this protection,  it is against Experts-Exchange policy to help with this type of activity.
