If you open the utility via Start-menu, it will be called 'Disks'. If you are on Manjaro like me (or any Arch-derivative I imagine): Here is a guide how to automount your NTFS-partitions: any partition/device really. Sdf is the specific device, in this case my USB-adapter. It's 1 command: sudo dd bs=4M if=/dev/sdf of=/home//rpi.img You never know when you have to wipe OSes or partitions or the drive just fails. Always save a backup in more than 1 place. In case you want to move the backup to your Windows partitions. It's also easy to mount/automount your NTFS partitions if you want. 'sudo blkid', 'sudo lsblk', 'sudo fdisk -l'.Īnother, graphical way, is using Gnome-disk-utility. You might need 'sudo' before the command. To find out which device it is on your system, run lsblk, blkid or similar in terminal. I make backup image in Linux because why wouldn't I have Linux installed. Plug it into adapter and plug adapter to PC. Shutdown your RPI, take out the microSD-card. I use an adapter for this: one of these from any shop. It’s in the System Tools section of the start menu. Launch gparted from within the Raspberry Pi OS GUI. Boot your Raspberry Pi off a different microSD card.ģ. Put your source microSD card (the one you want to copy) in a reader and connect to your Raspberry Pi.Ģ. To do the shrinking, you’ll need a USB microSD card reader and a second microSD card with Raspberry Pi OS on it.ġ. Then you can copy just your partitions over to the USB drive. So the solution is to shrink the rootfs partition of your microSD card down to a size that’s just a little bit bigger than the amount of used space. If you don’t shrink the rootfs partition, you will end up copying all 64GB over to your external drive, which will take a lot more time to complete and will require that you have at least 65GB of free space. What’s particularly frustrating is that, by default, the dd file copy process makes an image out of ALL the space on your microSD card, even the unused space.For example, you might have a 64GB microSD card, but only be actually using 6GB of space. img.gz file you create in the tutorial above should be much smaller than your source card, you still need enough space to accommodate the uncompressed. If you want to make a disk image of a microSD card, but don’t have an external USB drive of a greater capacity, you have a problem. How to Shrink a Partition on Raspberry Pi You can copy this file to your PC, upload it to the cloud or send it to a friend. This process will also take several minutes but, when it is done, you will end up with a reasonably sized image file called. sudo dd if=/dev/mmcblk0 of=/myimg.img bs=1M count=7000 The amount of data is equal to count * block size (bs) so 7000 * 1M means 7GB. So, to be on the safe side (better to copy too much data than too little), we rounded up and set dd to copy 7GB of data by using count=7000. For example, in our case, we had had a 16GB card, but after shrinking the rootfs down to 6.5GB, the card only had about 6.8GB in use (when you count the /boot partition). However, if you shrank a partition on the source microSD card, you’ll need to use the count attribute to tell it to copy only as many MBs as are in use. sudo dd if=/dev/mmcblk0 of=/myimg.img bs=1M Copy all your data to an img file by using the dd command. However, you can’t and shouldn’t do that if it’s already mounted.ĥ. If your drive isn’t mounted, try rebooting with the USB drive connected or you can mount it manually by typing sudo mkdir /dev/mysub to create a directory and sudo mount /dev/sda1 /dev/myusb to mount it. Your USB drive will probably be mounted at /media/pi/. Actually it is a lot more than that but I am going to refrain from a stream of ’ll see a list of drives connected to the Raspberry Pi and the mount point name of each. So I am curious - has anyone else ran into this before ? Is there a workable solution or do we just end up writing our own version of CopyImage? This is just so incredibly annoying. WTF ! This is the behaviour on WinNT4 but NO OTHER system performs like this!!! Which is correct ? Do we just use 0 ? ![]() If this flag is not specified, a new object is always created. Returns the original hImage if it satisfies the criteria for the copy-that is, correct dimensions and color depth-in which case the LR_COPYDELETEORG flag is ignored. Sure enough I checked on the latest MSDN docs for this and they read: > a new bitmap and uses BitBlt() to copy the image from source to target. > way, you could very easily create your own CopyImage() which creates > color depth in which you ' re running on the various machines. > The difference in behavior is either a bug in NT4, or due to the > wouldn ' t satisfy your request is if it's a different bit depth. > you're asking for 0 width and height, the only way the original ![]() > that you will get back the original if it meets the criteria. ![]() I don ' t think I understand - the docs for LR_COPYRETURNORG state
