Can't erase my Sdcard...
Hi guys
I have a SDcard sitting in a USB card reader... I have this in /etc/fstab : /dev/sdc1 /media/claude/SDCARD vfat rw,user,auto,exec,gid=100,uid=1000,umask=002,utf8,codepage=850,shortname=mixed 0 0 so it is mounted in /media/claude/SDCARD... I have those rights: drwxrwxr-x 11 claude users 16384 janv. 1 1970 SDCARD So far, so good...but I can't erase anything ( files/directories ) on this memory...) When I launch a rm -R * command, everything seems to be erased but , next time I'll plug the Sd card, all the supposedly erased files are still there...which, to be honest, confuse ma a lot ( I'm the owner, I'm root...and I can't erase this memory) 2 quickies 1) what am I missing ? 2) what to be done to completely clean this SD memory (FYI, I've tried erasing under Seven..lifting the perms, erasing..but same stuff, data still present... Completely lost...help greatly appreciated !!! rgds |
How are you removing the card? Are you using umount and sync or just unplugging it?
Many (all?) SD cards also have a physical switch on the side that switches them to read-only, have you played with that? |
You've checked the write protect switch on the SD card...? :)
Play Bonny! :hattip: |
Hi
I'm doing an umount and then unplug...(sync ? dunno what it is...) of course, The card is not write protected by the lateral slider... As mentionned above, I can acces SDCARD...I see all the files/directories and throw rm command...it seems to erase the whole thing... I have the feeling, but dunno if it is true... I'm not erasing the card...but a copy of it !!! drives me nuts this thing !!! |
oh I don't know
did you try using gparted? just unmount it delete it the partition reastablish it in the format you want then click the arrow bada bing bada boom dont for get that if you start it off the command line you got a be root. |
Hi
I've tried Gparted but almost everything is greyed out... I came to the conclusion that the part id dead...I've tried to write on it...no success, then tried to kind of format it using dd...no success !!! You may read, but not write which is pretty ennoying ( but hopefully, I've got a spare 32Gb which is working fine) Anyway, many thks for yr concern and yr support Cheers |

Can't access my partition...
I see it, half full but the Partition menu does not give me any access ( resize,format...).everything greyed, "new" has no action... Dead !!! |

command line starting. Code:
$sudo gparted |
o Tay if that does not work for ya then try this next
Code:
sudo blkidthen Code:
sudo cfdisk /dev/sdxwhen cfdisk opens up you'll see it then you can delete, create new, and set type, and other things off the command line (terminal). make sure you select write, when you are done, it will then ask for confirmation , type 'yes' so it sticks then quit. example: Code:
that'd be the first one in this case. Code:
sudo cfdisk /dev/mmcblk0Code:
Disk: /dev/mmcblk0I can delete everything then start over if I like. using the arrow keys - first select the area partition raw area you want to work with then select what you want to do with it, then enter, type size if it asks you 10.7MB or 10.3GB the MB and GB being the most importaint so it knows what you are talking about. formatting the new partitions may now be required,, I don't know everything :D but when I open it up again in Gparted I get that little ! then I just tell it to format it then do it then the ! goes away. |

Bad luck...sudo cfdisk /dev/sdc1 gives a fatal error. can't open disk... Below, screen copy... Thks anyway Erreur fatale: Impossible d'ouvrir l'unité de disque Appuyez sur n'importe quelle touche pour quitter cfdisk |

sudo cfdisk /dev/sdc <----- notice no 1Quote:
