corsarul2012 Posted June 7, 2015 Share Posted June 7, 2015 (edited) Hello, I decided to install Windows via USB and i don't know what happened, but after re-formatting my USB, it had less space than before. Initially it was having 7,89 GB and now it has olnly 7,44 GB. What could I do, to recover the lost space?(I have treid command with clean and create partition primary with cmd, but it had no effect). Thanks in advance! P.S: I wouldn't like to resoft the USB, but if I have to do so... Edited June 7, 2015 by corsarul2012 Quote Link to comment Share on other sites More sharing options...
SteveSi Posted June 7, 2015 Share Posted June 7, 2015 You may need to repartition it, use Windows Disk Management (diskmgmt.msc) to look at the drive partitioning and re-partition.. Quote Link to comment Share on other sites More sharing options...

SteveSi Posted June 7, 2015 Share Posted June 7, 2015 Google for diskmgmt.msc - plenty of youTube videos, etc. Quote Link to comment Share on other sites More sharing options...

Mr-Protocol Posted June 7, 2015 Share Posted June 7, 2015 You may need to repartition it, use Windows Disk Management (diskmgmt.msc) to look at the drive partitioning and re-partition.. Windows does not see multiple partitions on USB thumb drives. To the OP: Hook it up to a linux box and wipe it with dd at least the first few sectors. Then you should be able to reformat it and have all the space available. Quote Link to comment Share on other sites More sharing options...
corsarul2012 Posted June 7, 2015 Author Share Posted June 7, 2015 Will it work with Ubuntu format tool? Quote Link to comment Share on other sites More sharing options...
Mr-Protocol Posted June 7, 2015 Share Posted June 7, 2015 Maybe, but wipe it with Ubuntu first to blast out any partition table or MBR that may be on there. Then use the formatting tool on whatever OS you want. Quote Link to comment Share on other sites More sharing options...
corsarul2012 Posted June 8, 2015 Author Share Posted June 8, 2015 Ubuntu format had no effect :( Quote Link to comment Share on other sites More sharing options...
fugu Posted June 8, 2015 Share Posted June 8, 2015 I'm not responsible for any damages so make sure you know what your doing! but you might try $ sudo apt-get install gparted $ sudo gparted find which drive your usb is (/dev/sdc, /dev/sdd, etc) so you don't nuke your hard drive exit gparted, then $ sudo dd if=/dev/zero of=/dev/ofyourusbdevice bs=1M then go back to gparted, recreate the partition table, then format it how you want, (for windows probably fat32 or ntfs) Quote Link to comment Share on other sites More sharing options...
Mr-Protocol Posted June 9, 2015 Share Posted June 9, 2015 Easier option with Ubuntu: lsblk Will list block devices and associated partitions if they are recognized. Example of output: protocol@Zion-VM:~$ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 80G 0 disk ├─sda1 8:1 0 78G 0 part / ├─sda2 8:2 0 1K 0 part └─sda5 8:5 0 2G 0 part [SWAP] sr0 11:0 1 1024M 0 rom protocol@Zion-VM:~$ Find your sd[X] for the one matching thumb drive. Make sure to use the name of the type "disk" and not "part". Wiping out the partitions will not help you. If I wanted to wipe out my hard disk with the above output, I would use sda instead of sd[X] below. Chances are your USB drive will be /dev/sdb or /dev/sdc. sudo dd if=/dev/zero of=/dev/sd[X] count=5 It will default to 512 block size, and you really only need count=1, but a few extra won't hurt. Make sure to wait until the program returns "Records In" and "Records Out". It tends to hang a bit when writing to removable media due to the "lazy write"/write cache. Then just reboot the computer just to make sure it actually wrote the data, and format with whatever OS you want. Should do the trick. If that doesn't fix it, I would begin to think there are hardware issues with it. Quote Link to comment Share on other sites More sharing options...
UnKn0wnBooof Posted July 31, 2015 Share Posted July 31, 2015 I know I'm late BUT everything could actually be done from Windows ;) Press WinKey + R (Opens a run box) Type "dispart", press "OK" Grant Admin priviledges Type the following commands, each line represents a return: list disk select disk [disk number that matches your drive size] clean convert mbr create partition primary format quick Done! :D Quote Link to comment Share on other sites More sharing options...
