How to format larger SD Cards for Raspberry Pi

How to format larger SD Cards for Raspberry Pi

If you have ever used an SD card with a capacity of over 32GB you may have run into some problems when using it with your Raspberry Pi. The reason for this is that SD cards of larger capacities will by default use a format unsupported by the Raspberry Pi to allow for the use of the full capacity of the SD card.

By default, many SD card formatters will format cards below 32GB as FAT32, and cards that are above 32GB as exFAT (which is not supported by Raspberry Pi). Fortunately, it is relatively easy to work around this problem using a minimal number of steps.

Formatting the SD Card

Before continuing, we’d like to point out that we did not have a larger capacity SD card to test this on, however, the principles remain very much the same. On a secondary note, you will need either a Windows or OS X computer with an SDXC card slot. Also, it is worth bearing in mind that reformatting SD cards will result in the loss of data, so make a backup first if there is anything important you wish to keep.

First, we must download and then use the SD-CARD associations formatter application. This is available to download from the SD-CARD association’s site. After you have this downloaded and installed we can move on to the preliminary formatting of the drive.

Strangely enough, the method of formatting SD cards seems to differ whether you are using a Mac or a Windows PC, even though the software is much the same. If you are using OS X ensures that you check “Overwrite Format” and select the “Option” button in which you must then check “Logical Address Adjustment” as yes.

 

In Windows this is slightly different, simply click the “Option” button and select “FULL (OverWrite)” for the format type drop-down and “On” for the format size adjustment dropdown.

Formatting as FAT32

To finalize formatting our “fat”, if you pardon the pun, SD Card we must reformat it so that it can be recognized by our Raspberry Pi. Thankfully there is a neat little tool we can use to reformat our SD card as FAT32.

The tool can be downloaded from Ridgecrop Consultants Ltd, unfortunately, this is for Windows only but alas OS X provides the Disk Utility application which can also do this for you. You should now be able to successfully use NOOBS off of your Raspberry Pi since the boot loader is now utilizing a recognized format. Take care when using the FAT32 Formatter for Windows by ensuring that you are formatting the correct drive, or else it could become a rather costly error.

Installing Windows 7 Without a Hard Drive

How to install windows 7 in DVD-R (W) /CD-R (W) drives – WME or Easy Install software. Windows Operating System comes free with your PC. Microsoft has bundled the operating system with the hardware so that you can run it without any additional software. But certain software programs are available free on the Internet.

These software programs can be downloaded and then installed by keeping the DVD-R (W) /CD-R (W) drive in the computer’s USB port.

System Requirements

System Requirements for installing a new copy of windows 7 in DVD-R (W) drives – WME requires both Windows XP Home Edition and Windows 7 Ultimate Product. You can check your computer’s requirements for running Windows XP Home Edition first. Windows XP Home Edition and Windows 7 Ultimate Product are different operating systems, but they have similar hardware architecture so that installation of one on the other can be a simple matter.

How to install windows 7 in hard drive partition –

Windows XP Home Edition and Windows 7 Ultimate Product can both be installed in a “barebone” configuration. A barebone configuration means just that, it is a configuration where nothing is pre-installed on the hard drive. In this case, the hard drive is simply formatted and Windows is installed in its default settings. In order to install windows 7 in a complete configuration, you need to include a software package such as Windows Media Player Recovery to repair your media player.

How to install windows 7 in a new partition –

In this case, the computer will not contain an existing partition for the installation of Windows. The only available option is to create a new partition. New partitions can be created using the Disk Partition Wizard. Just like when planning to format a physical drive, you will need to determine the disk formatting options. You can choose from FAT, NTFS, or FAT32 partitions.

If you are planning to install windows by booting up the computer, then you should use the Windows installation tool that was installed with the original installation process. The Windows installation tool will allow you to boot up the computer and then run through the installation process. If your computer has not been turned on, you can boot up the computer and then go to the settings. There, you will find the storage drives tab. Click on the existing disk that has the Windows installation tool on it. Use the browse option to select the drive that corresponds to your USB drive.

How To Create iOS 7 Icons In CSS

How To Create iOS 7 Icons In CSS

Introduction

With iOS 7 Apple went for a clean yet minimalistic design with their UI. This has allowed for the creation of certain iOS 7 icons through the use of CSS and CSS only. Images are no longer required to replicate the design and function of an iOS icon. Unfortunately, this tutorial or CSS trick poses no real-world value as it doesn’t really have a use for itself, although the end effect is certainly satisfactory.

What we will be creating

As you can see if you hover over either icon it will start to jiggle about a lot like the classic iPhone app animation that we are all familiar with. You can of course view the code from that embedded preview above, which is fine to copy however I will be explaining it all below. You may notice that the CSS animation goes a little wrong in that embedded CodePen, but I can assure you that it does work when tested locally anyway.

The HTML Layout

We will be using a very simple HTML layout as most of the magic is worked through the CSS for website design, not much really needs explaining here as it is pretty self-explanatory.

How To Create iOS 7 Icons In CSS

Here we essentially have two wrappers, one for the weather icon and one for the notes icon. Inside these two wrappers, we have the various components that make up the whole of the icon.

Weather Icon CSS

Although this isn’t necessary to the CSS trick I suggest you set a background other than white to ensure that certain elements of the icons show up more easily. I used #5fadd3 in this example.

The weather icon is deceptively simple to make. The base consists of a single 100 pixel by 100-pixel tile with a border-radius of 20 pixels, this gives an effect close enough to that of a true iOS icon. The sun is quite obviously a relatively small circle using a border radius of 100 per cent and of course the typical yellow colour of the sun. The cloud is the most complex part of the icon consisting of two oval shapes each of which vary in dimension and a small circle.

We will start with the main icon and the sun:

 

To simulate the icon of weather icon I simply used a gradient ranging from top to bottom specifying the colours shown above. To help with this step I did use a reference image of an iOS device running iOS 7, however, I of course have already done this for you.

We haven’t quite yet got to implementing the keyframes of the ‘jiggle’ animation so I won’t go into too much detail about that now. The sun is 40 pixels by 40 pixels again this was me trying to get the dimensions right relative to the real icon. We use a 100 per cent border-radius to ensure that we get a perfect circle, next we have to do a little bit of readjustment to get the sun in just the right place.

The reference weather icon image has slight transparency allowing the sun to shine through the cloud. To achieve this effect I applied transparency of 0.9 to the parent object. The following constituents of the cloud could then all have transparencies of 1.0 as they are relative to that of the parent object. Although this part is arguably rather complex there really isn’t too much to explain here as it is all about positioning the objects in just the right place.

Notes Icon CSS

The notes icon is somewhat easier to make as it doesn’t involve any complex shapes, although it can be quite finicky to get the lines in just the right place. For this icon, I set the main background colour as being the golden yellow colour. I then used a second element with a rounded left and right bottom border which overlaps the original gold colour. The lines were mostly made by repeating elements however there were a few exceptions.

 

The above CSS makes up the top half of the notes icon. Again as before we used a width and height of 100 pixels and a border-radius of 20 pixels. Note that we used the border-box tag on the note element as the border placed at the top of it causes the height of the icon to increase by 3 pixels. However, the border-box tag overrides this.

 

In the icon, I used three lines to match that of the reference notes icon. However, the final line had to be slightly altered so that it didn’t clip over the edge of the icon and cause it to look a little odd. To fix this we simply specified width of 90 pixels and a border radius of 3 pixels.

The ‘Jiggle’ Animation

The ‘Jiggle’ animation is fairly basic albeit may look slightly complex which is mostly due to the many prefixes that you see such as -WebKit, -mox and -o. Likely there are only really a couple of parts to understand.

 

The various keyframes are for Internet Explorer, Safari & Chrome, and Mozilla Firefox. As you can see this animation causes the icons to move one degree anti-clockwise and one degree clockwise roughly a couple of times a second. As you saw in the CSS code earlier we simply only have to call this animation. We use the infinite tag to declare that the icon animation should loop when the user has hovered over.

How to make Raspberry Pi use the Full Resolution of your Monitor

When I first used my Raspberry Pi, I wondered why the full 1920×1080 resolution of my monitor was not taken advantage of. In the preferences of the Pi, the resolution was set to the largest available (not 1080p), but after some research, I found you can change a few settings in a configuration file that will remove the black bars (‘overscan’) and enjoy your Raspberry Pi fullscreen.

To change the settings, we need to change a few things in /boot/config.txt. From the Linux command-line interface (without going into the GUI desktop), enter:

sudo nano /boot/config.txt

This will bring up the contents of the config.txt file, where you are free to edit it. As the instructions say, find the line which says #disable_overscan=1 and uncomment it (i.e. remove the #). Normally this should be enough, but if you used NOOBS (New Out Of Box Software) then there are a few more things you need to change.

Raspberry Pi

As you look further down the page, there may be another section with overscan and borders, and yet another disable_overscan=0, all of these which override our disable_overscan=1 above. Therefore, you’ll need to comment (i.e. add a # before each line) that mentions overscan (there are four), and lastly change disable_overscan=0 at the bottom to disable_overscan=1 and make sure it isn’t commented out.

Here is that last block of code as it should look after our changes (note your overscan number values may be different):

#overscan_left=24
#overscan_right=24
#overscan_top=16
#overscan_bottom=16
disable_overscan=1

Once you’re done, you can press ^X (or Ctrl+X) and follow the instructions on-screen (i.e. typing Y to save) to save your changes. You may need to reboot your Pi for the changes to take effect. If you have any troubles or can’t get this to work, leave a comment below.
