Bonjour,
après une mauvaise manipulation j'ai perdu la partition caché de mon archos lors d'une tentative de réparation.
Celui- ci ne démarrait plus que sur l'écran recovery.
______________________________________________
Backup the hidden partition
  • Open up your terminal (Go to Applications>Accessories>Terminal (for Ubuntu)) and type in the following:

sudo fdisk -l


  • The result should kinda look like this:

Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x6c1441e5

Device Boot Start End Blocks Id System
/dev/sda1 * 1 19107 153476946 83 Linux
/dev/sda2 19108 19457 2811375 5 Extended
/dev/sda5 19108 19457 2811343+ 82 Linux swap / Solaris

Disk /dev/sdb: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x4dd2f678

Device Boot Start End Blocks Id System
/dev/sdb1 1 19428 156055378+ c W95 FAT32 (LBA)
(You may get the sdb1 as something else like sdc1 or sdd1 or sde1 etc. depending on your system configuration.)

**Note:: you may have to change the sdb to what every you get in your system when you do a sudo fdisk -l



  • Now copy the unassigned space using dd commnd

dd if=/dev/sdb of=/tmp/archos-hidden.dump bs=8225280 skip=19428


  • Now say "Done" on the Archos and restart the device
