Im trying to partition my hd but it is write protected. what can I do? How do I remove write protect from a HD?

check your bios settings

You may find the only way out is to perform a low level format which wipes everything off the hdd. Generally one can be downloaded from the hdd makers website. Then run FDISK to partition and format as normal. Good luck - keep us posted.

Is there no cmd to un-write protect the HD?

LOCK Command ************ SYNTAX LOCK [drive:] drive: Specifies the drive that needs to be locked. UNLOCK [drive:] drive: Specifies the drive that needs to be unlocked. EXAMPLES lock c: - This would lock the C: drive When typing the above command you will receive the following prompt: WARNING: The LOCK command enables direct access by programs that can CORRUPT file names and/or DESTROY disk data, resulting in the loss of files on your disk. Are you sure (Y/N)? unlock c: - This would unlock the C: drive It is important to know that if errors occur indicating that a process such as fdisk or a setup of a new program or operating system occur indicating that the process cannot continue because the hard disk drive is locked that using the unlock command will resolve this issue.

You need to know how and why it was write protected in the first place. Maybe a password is involved. e.g. it may have been on a slave on a network where the user(s) cannot be allowed to mess with the o/s. Good luck - keep us posted.
