Previously, I started a post of http://forum.tabletpcreview.com/del...-moving-recovery-partition-usb-works-not.html trying to seek out the facts from many conflicting information. I believe I have done enough research to give a walkthrough. Acknowledgements - The following members had provided me their experience and inspirations. Thank you! St Lamar, dprice7, baxter, laaf2005 Background I own a 32GB Dell Venue 8 Pro. Out of the box, I get just a little over 10GB of free space. The #1 reason is due to the Recovery Partitions installed by Dell. Here is a snapshot: Code: 1.00 GB (Recovery Partition) 500MB (EFI System Partition) 22.00 GB (OS) 5.51GB (Recovery Partition) Note that there are 2 Recovery Partitions. And there is in fact a 128MB Reserved Partition between EFI and OS partitions. But it is a Windows thing and should not be touched. The 1st Recovery Partition (some of you reported to being 500MB) is WINRETOOLS. Which I believe is the Recovery Environment. One that gives you tile menus of Refresh, Reset, Restore, Boot, etc. The 2nd Recovery Partition is the actual system image that comes with your V8P that can be used to build factory image. What you need micro USB to USB A female adapter (a.k.a OTG cable) 1 (prefer 2) 8GB USB drive That's it. No 3rd party software needed. Moving Recovery Partition NOTE: Do not trust Dell's Recovery. Do not use Dell's Recovery and Backup software to move Recovery Partition because you will ended up with a USB that boots up and asks for power to be plugged in. I don't understand how this could get past QC. The proper way of moving Recovery Partition is use Windows's "Create a recovery drive". Open the search box and type "recovery drive" and click on Create a recovery drive. Leave the check box checked to copy recovery partition to USB. Click Next It will format the USB drive and make it bootable and copy the recovery partition over. The process will take a while depending on your USB drive. Allow at least 15 minutes In the end, you have an option to delete the recovery partition. Don't do it until you do some sanity test. To verify your USB drive Leave the USB connected and shutdown your V8P Wait until the V8P is completely shutdown press the power button, you will see the screen blink a little, immediately press "Vol -" once You will enter BIOS, go to Boot you make "Boot Option #1" your USB drive Touch ESC and save You can now boot into USB Choose US (Keyboard Layout) Choose Troubleshoot Choose "Reset your PC" Choose "Windows 8.1", there is a short wait and you will see some options You should now have good feeling that the USB works. Now, make another Recovery USB following the same steps above. In the end, choose "remove recovery partition". Congratulations. You now have 5.5GB more. Reset to factory default If you now want to reset your V8P to factory condition, you can boot back into USB and continue where you left off after "Reset your PC" After you touch "Windows 8.1", there is a short wait and you will see Hit "Next" You will be asked: I choose "No". (Note that you will only be asked once, if I later "cancel" and restart, it will not ask me again) Now you will be given the options of The two options all ended up the same. But the option 2 is slower as it attempts to erase your personal file with random data. You may want to use it if you have been using your V8P and now want to sell it. After you confirmed with 1st option, it will take about 20 minutes and V8P will reboot and you will be presented with initial setup. Your V8P is now good as new but the recovery partition will not be restored. That's what the USB drive is for! What about the 1GB Recovery Partition? I'm glad you asked! This partition is no longer needed since you can do it with the USB drive (in fact, it only uses 200MB). So I nuked it too! Here is the procedure: Search for Command Prompt Run as Administrator Bring up the keyboard and enter "diskpart" "select disk 0" "list partition" verify that the Recovery Partition is partition 1 "select partition 1" "delete partition override" "exit" - your recovery partition is now gone enter Disk Management (file manager -> computer (on top) -> Manage) The first partition is now freed. Create a simple volume (I choose cluster size of 4096, more on this later) Now you get a 1GB or 500MB D: for your use. What to do with this D:? What I did is I turned off hibernate (powercfg /h off) and then made this partition for my Windows pagefile.sys. You can find the instructions in the web. If I have time, I will write some more details on this. I don't know of any way to merge this partition to system partition since there are several partitions in between. After all this, I have 17.0GB free on my C: This is even after I installed all the recommended updates. Now I want to challenge you guys out there to free up more than 20GB on a 32GB V8P! Are there other ways to backup? Yes, Microsoft provides another way to backup your partitions. It backs up your current drive status including the system partitions but not the 5.5GB Recovery Partition. You can access the tool from Control Panel, then "File History". Toward the bottom left, you will see "System Image Backup". Launch it. It will backup your partitions (excluding the 5.5GB Recovery Partition). You can save the backup to a microSD card if you want. For me, the tool says I need 11GB but it only used 6GB or so because it compresses the files. However, I suspect it will refuse to save to an 8GB microSD card. Note that the drive you used for back up must not be FAT32 as files > 4GB will be created. Since the recovery USB is FAT32, I think this eliminates the possibility of using the same drive. The advantage of System Image Backup is it will backup your current state, i.e. your installed Windows with applications, documents and also your Metro apps (you can keep your version). The disadvantage is it will take up more space and it is not factory image. To restore, you can use the 8GB USB drive (or your can use the same "Create a recovery drive" tool on a 256MB USB drive and choose not to copy recovery partition). Instead of "Reset your PC", choose "Advanced options" and "System Image Recovery". I have not tried this System Image Recovery before so I cannot say it works or not. (Edit: laaf2005 confirmed that it works, see his post in Page 3). If you have a spare 16GB microSD, I suggest that you do it anyway. Backup image will be saved under a single directory, and you can backup the directory to your other HDDs and free up your 16GB microSD. Also, since microSD is used for restore, you can replace the USB boot drive with power.
