Encrypted an internal hard drive with DoE compliant enrcyption is disk utility, need to format witho

[zeuzzz]

Ok so I lost the long password I made for one of my secondary hard drives. I can not even format the disk as the option is greyed out in disk utility. Is there any way to do this on a mac ? I don't care about loosing data it was basically empty anyway.

You should be able to do it anyway
Have you tried the Partition tab?
Select 1 partition and hit apply

Thanks but I think since I did the DoE compliant encryption this opition is not available to me. All the options you just linked to are blank in my OS. See attachments.

I need to get access the drive and format it in a way before disk-utility tries to mount the image (which I think is where the encryption comes in?) But I cant see a way to do this in the standard version of OSX.

Use terminal:

[B]diskutil cs list[/B]

This will list your encrypted HDD's (Disconnect everything to avoid problems, leaving your encrypted HDD ONLY, you don't want to lose any data, do you?)

Copy the UUID, it's in this format:

XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX

And do this:

[B]diskutil cs delete XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX[/B]

After that, go to Disk Utility and you should be able to format it
