I ran into a major problem installing Linux on a flash drive and was hoping someone could give me some assistance: First of all, I am a newbie using a Linux Cert Guide for study purposes and went through a project for installing Fedora 13 (I need to use 13 since it is for an upcoming class). I installed the Basic Installation with GNOME on a flash drive and it was just fine (ext4 filesystem as well). I tried a second installation on a 64gb flash using ext3 filesystem, Basic Install and added almost all optional components (except Virtualization). The drive did not boot properly and now it cannot be formatted. It reports "media not available" when I view its properties. I have also tried installing the Basic Install on a 32gb SD card and it also did not install properly, and the SD card now reports that it has a RAW format with a 31MB capacity (rather than 32GB). Here are some utilities I have tried: - Disk Management from Windows 7...sees it as a 31MB drive; cannot format it - diskpart from the command line. Did not work - MiniTool Partition Wizard..did not allow me to fix the MBR - EaseUS Partition Master...may work but $45 to register (which is fine) but did not see the flash drive when Windows 7 did. It did see the SD card. - GParted...also unable to format I believe I will need a program to rebuild the MBR for both the 32GB and 64GB drives but I have been unsuccessful. I also tried BootIce, utilities in Ubuntu and Fedora but with no luck. I would like the SD card to see its full 32GB capacity and allow me to format it, as with the 64GB flash drive. If anyone has some suggestions or have had similar experiences and found a solution, I would be greatful. Being a newbie, I'm not nearly as seasoned with the command line as I am with DOS so any help would be appreciated. Thank you all.
