Disk1s1: device is write locked

[Maria_33]

Hello,

I have a problem with my mac and I hope someone here can help me...

When I turn on the mac, it iniciate in utilities. I run disk utility and everything appears to be ok so I start in single user mode. When I run fsck comand everything is ok, but when I run /sbin/mount -uw the message is: "disk1s1: device is write locked"

I have data unsaved inside the mac... What can I do to start it normally or to save the data? Thanxs!!

Hi Maria and a warm welcome to Mac-Forums.

disk1s and it's like, usually refers to your Recovery Partition which is a vital part of your Mac's Operating System (OS), allowing you to go into Recovery Mode from which you can carry out First Aid on your HDD, re-download the current OS and much more.

It is not to be tampered with.

The Link below, a little dated, gives a very lengthy & complicated explanation of all of this.

Maria,
It sounds like your Mac starts in Recovery mode each time. Please try this: Start the Mac and immediately hold down (keep holding) the Option/Alt key. This should give you a startup choices menu (icons). Select the normal drive and click the right arrow button to start normally.
Tell us the result.

Thanxs for the responses!


Gsahli when y press the alt button I only have the recovery partition as option and when y choose it, it opens utilities again...

Iwt thanxs for the info, is so interesting.

I think my best option is reinstall the full system and try to recover the data

Rather strange and it sounds like that's your only option as it sounds like you don't have a working system, unless you made a bootable backup preferably using CCC or SD! that you could use.

What ghapopens if you just boot and press no buttons.

It really does sound like the Mac's startup drive has died. Do you have a Time Machine or a clone backup? If so, you could startup from them?

 

[Maria_33]

N, Ferrarr, I dont have a clone or a timemachine :S

If you really really really are not able to boot into the main partition on the storage (HD or SSD) inside this computer...then booting from an external source could be the next thing to try. External source being for example...an external HD with the MacOS installed on it.

And just so we know in case it helps...can you tell us exactly what model Apple computer this is? More specific than "iMac, MacBook Pro, MacBook Air, etc.". Lol

Also when you ran Disk Utility...did you try "Repair Disk"?
