Hi Patricia, Ok, I've got my disc and after a few hours of struggling, I've partitioned it into two partitions successfully.
I plugged my new dis into a usb port. It showed on my desktop. I opened disc utilities and selected the disc in the table of all available discs. I then chose to erase it to be sure that the formatting is what I want. I did not wish to use the disc with any other operating system, nor did I want to use any backup software that came with it so I chose the mac os journalled and GUID option with it. The disc was erased and reformatted. I then made sure it was selected in the table of available discs and pressed "partition" button in the toolbar. Looking from the left to the right, you first have the name of your disc. That's reassuring. :) Then you have the pie chart area. You need to interact with it. You will probably see there the name Untitled with the number of GBs or TBs and you will also hear VoiceOver say whether it is selected or not. It says something like "selected, yes". This is again to reassure you. At this point, this is the only partition available after reformatting the disc. Stop interacting with the pie chart area and move to the right. You will encounter the name of the existing partition, which is in all likelihood "Untitled", and then the same name but this time it will be in an edit field so that you can type a new name for a new partition. Do so. I just called it for now "partition1'. Then move to the right and you will see the size of the original partition - in my case, it was 2 TB i.e. my entire disc space. I changed it to 1 TB which is what I wanted for the new partition. Then move right skipping through buttons like "add" and "remove" and "cancel" till you get onto the 'apply" button. Press vo+space on it. The resizing and partitioning will begin. When it's over, the "done' button at the far right will become active. click on it. You will find yourself back on the table of available discs. Go back and reactivate 'partition' button in the toolbar. Find the pie chart area, and you should now have two entries in there: "partition1" in my case and Voiceover will announce how big it is and whether it is selected or not, and move to the right to hear "untitled' with its size and it will probably say selected no. This pie chart area is a good reference point to make sure how many partitions you have and what size they are. If two Partitions are enough for you, then close disc utilities and on your desktop you can rename the "untitled" partition to whatever you want. I assume you know how to rename files and folders by pressing enter on them and enter again wen you have typed in a new name. I must say that I have failed to resize the existing partitions after I have created them. When I attempt to resize them, i.e. I highlight a partition I want, and then right a new value for size in the edit field, instead of changing the size of the selected partition, disc utility creates a new partition making another partition smaller. There's obviously something here I fail to grasp. When you put VoiceOver cursor on the pie chart area, it tells you to drag the slider to the desired size of your partition but I don't know whether we can do it without sight. I tried and tried various tricks but failed. If by any chance you create an extra partition you don't want, you can select it in the pie chart area with vo+space and then press "remove" button. Vo+spacebar will highlight / select a partition in the pie chart area if it is not already selected. Listen carefully to what VoiceOver says: it wasn't obvious to me initially because of the way VoiceOver announces it. It says: "select yes" or "select no". So at first I just didn't get it. I hope this will help you somewhat. Best wishes Andrew > On 14 Dec 2015, at 17:21, Patricia Solis <[email protected]> wrote: > > Hello: > I’m sorry, I should have been more specific.
