Disk Utility won't allow Master Boot Record?

3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to MBR then click on the OK button. Set the format type to MSDOS (FAT32.) Click on the Partition button and wait until the process has completed.

Did you do the above?

I had the same problem. When you erase the media from Disk Utility select...

Format: MS DOS

Scheme: Master Boot Record

Click Security Options and drag the slider one to the right.

This will properly erase the media.

Im having the same problem. I want to format my USB (Kingston) to "master boot record", but you cannot change the scheme on El Capitain. there is no options, no volume . you can only select partition, but there is no option to change to master boot record. you cannot change it from scheme 'guid partition map'. you can name the partition, choose the format, thats it. on the left is a blue circle, it has a facility to change how much blue there is like a pie, but i don t know what this means.!! I want to use this USB for djing on pioneer cdjs. unless i do this apparently the usbs won t work on the pioneers. can you help. ?!!

Hi I just found out how to do this I hope.!!!

but it will erase everything so you need to back up or have a new USB,

So..

when you open disc utility, choose the top option on your USB. the Tool bar should then appear at the top of the screen box. Select 'erase'. there is a dropdown box that appears, you can select the 'scheme' here to 'master boot record.'. its the third option, you change the USB partition name as well, then you select 'erase" then when its done . you can see the white box below that the "partition map " has changed to 'master boot record'. you can then change the format if thats what you need to do after that. hope this helps. Im not to techy though.

Drive Preparation

1. Open Disk Utility in your Utilities folder.

2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.

3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to MBR then click on the OK button. Set the format type to MSDOS (FAT32.) Click on the Partition button and wait until the process has completed.

Hi there, I have a Lacie 2big thb disk, 8tb, I'm trying to partition it to MBR, but I'm not given the choice to select MBR, it's not active in the window in disk utility, what am I doing wrong here? Do I have to set each partition at max 2TB?....

Hi Kappy, Thx for your reply. I actually did that, but couldn't select MBR as it wasn't "active", only option was to choose GUID or Apple.... :-(

Probably the drive is already partitioned MBR and formatted NTFS (it's a new drive.) So all you need to do is reformat it using MSDOS in Disk Utility or FAT on a PC.

You can also partition the drive GUID and make two partitions. The first partition will be Mac OS Extended, Journaled. The second is formatted MSDOS. Use one for the Mac and the other on the PC.

Could also be the plain fact the Sony Blu Ray can not 'see' a HDD of that size ? you may need to partition it into more than one drive for the player to 'see' and mount the drive.

Custom mini.

Thx, I'll try that tomorrow, need some sleep now ;-) . Ill report back when I've tried the above.

Hi, I did format the two drives in OSX disk utility as MS-DOS FAT, went to windows, tried to make a stripped disk, the wizard did go all the way through, but in the end there poped up a window saying "there isn't enough space to make the desired action¨

The drives are not partitioned MBR, it's GPT partitioned, and I can't figure out how to partition it to MBR...

When I look at the drives in windows disk management, I can see there is 3 partitions on each disk, one at the start 200MB (EFI partition), one in the middle, the main disk 3.8GB, and one at the end 128MB. I'm only able to delete the middle and the last partition, NOT the first......maybe that's why I can't make it work...?

Should I try to use another disk management tool, instead of the standard in OSX and Windows?

How to partition and format a WD drive on Windows (8, 7, Vista, XP) and Mac OSX

Thx Alberto, I actually did all the steps mentioned in your link, but still no luck- one thing I couldn't do, and will have to look further into, is to initialise the disks...I'll be back ;-)

Are you actually selecting "1 partition" under Volume Scheme?

Hi, I've asked lacie, and they stated that once it was configured in RAID0 in OSX, then there is no return, and thats why it's not possible to make a RAID0 in windows... Bad luck :-(
