I have a big problem with my Emtec 8 GB SD Card. Currently there is a latest version of Raspbian on the card, I copied it through Win32DiskImager. Whereas the system actually boots with no problem I messed something with it and I couldn't use apt-get. I want a clean install of the OS but I can't delete the partitions in any possible way. Every time I want to delete partitions, in any possible way - diskpart,gparted (from live cd),paragon partition manager, easeus pm, and so on, it gets to the moment when I select to delete 2 partitions that are left (56 MB FAT32 and 7,3 GB ext4) and then I try to create new, only one and big 8 GB Fat32 partition - it throws errors depending on software used. The content isn't deleted because I can still boot Raspbian. I tried on different computers with different card readers... Any ideas? Maybe the card got corrupted somehow?
