How do you turn off write protect on your hard drive?

Yes, it is possible to protect your hard drive using the lock

command. E.g.

Lock sys: on - this will lock your partition Lock sys: off -

this will unlock it.

If you wish to lock a drive other than your main partition

simply substitute Sys: for the drive name.

I have a question for you: How do you turn ON write protection

on your hard drive to begin with? As far as I know you can't. Hard

drives were designed to be written on. You can't install an

operating system on it without writing to the disk.

The only way to prevent someone from saving something would be

through the operating system's security management. Before you can

disable what you think is write protection, you need to understand

what is protecting it to begin with.

Simple! Click Start Button > Type: Create and format hard

disk partitions > Enter > Right click on your drive (the one

that's write protected) > Click Offline > Right click again

> Click Online. Voila! tnt4real!

Some hard drives have a jumper on them for write protect. You

need to check the jumper settings

I just had this issue with one of my external hard drives. It's

an internal drive that I installed into an external case and

connects to my computer via FireWire. I knew it couldn't be a

jumper setting, because the drive has not been removed from the

case since it was put in there. I did NOT turn "ON" write

protection at any time. I've been writing to this disc with no

problems (daily) up until today. I tried copying a file to it, it

popped up a message saying that can not write to disk, disk is

write protected. I did nothing to cause this. No settings,

attributes, etc. After looking around a bit with no luck (not even

from here). I tried a couple of my own things. Found I could not

change attributes (cause disk is write protected).

I finally unplugged the drive from the firewire port and waited

a few minutes. Plugged it back in and let the computer "find" the

drive again, and all is well.

The write protect is in your bios. You select "enable" write

protect and it will ask you for a password. Note: not all bios

versions offer this option.

I'm considering cleaning up my hard drive of all unwanted ware,

especially spyware, and then turning on "write protect" for my hard

drive to keep the stuff out. I'll be using a flash pen to surf with

which can be cleaned much faster than a hard drive full of stuff

and zillions of places for things to hide.

The post above said you turn on this feature in the bios. Can

you elaborate on this as to how it's done? I have a Thinkpad r40

and can't seem to find anything on how to do it at ibm or


Thanks in advance...

I just had the same thing happen. Hard drive said write

protected. Not even a floppy at boot would work. Then I realized

when I hit delete for setup, both the hard drive and floppy were

flipped to write protect in the bios.

I had the same thing happen to an old P III 800mhz computer;

"write protected" message. After reading this I looked in CMOS for

a setting for hard drive write protect, I have never heard of this

as a bios option (floppy write protect yes, but not harddrive), did

NOT find a setting for write protect for either floppy or hard, but

I went ahead and did a reset CMOS to optimal setting anyway, booted

and all was right with the world!

Thank you for the helpful info. I had tried everything,

including fdisk/MBR, cloning to new hard drive, trying to do new

install of OS on fresh drive... all failed, thought motherboard or

IDE subsystem was hosed. Resetting CMOS WORKED.

If you download Windows SteadyState you have the option to limit

who has access to what. You also have the option to lock your HDD.

Everything you save will be undone the next time you boot. Here is

the link to the download for you.

Just copy and paste that website into your browser. Also this is
