As root. sdx is usually sdg or sdi, depending on other connected drives. > 5) if you retry from Konqueror, do you have a failure again? I don't see what you want me to do. The error message appears when I plug in / switch on the external drive. If/when it works the drive gets mounted on /media/<user>/<drive> and konqueror opens a window on its content. If/when it fails nothing is mounted and I can't do it from Konqueror (or I don't know I can :). > 6) what does "fdisk -l /dev/sdg" or "gdisk -l /dev/sdg" prints? root@junior:/home/thierry# fdisk -l /dev/sdg Disk /dev/sdg: 931.5 GiB, 1000204886016 bytes, 1953525168 sectors Disk model: HD103SI Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0xb6bc5d97 Device Boot Start End Sectors Size Id Type /dev/sdg1 63 1953520064 1953520002 931.5G 83 Linux root@junior:/home/thierry# gdisk -l /dev/sdg GPT fdisk (gdisk) version 1.0.3 Partition table scan: MBR: MBR only BSD: not present APM: not present GPT: not present *************************************************************** Found invalid GPT and valid MBR; converting MBR to GPT format in memory. *************************************************************** Disk /dev/sdg: 1953525168 sectors, 931.5 GiB Model: HD103SI Sector size (logical/physical): 512/512 bytes Disk identifier (GUID): 88036014-EE81-4D56-92FA-6212E6693E3C Partition table holds up to 128 entries Main partition table begins at sector 2 and ends at sector 33 First usable sector is 34, last usable sector is 1953525134 Partitions will be aligned on 8-sector boundaries Total free space is 5099 sectors (2.5 MiB) Number Start (sector) End (sector) Size Code Name 1 63 1953520064 931.5 GiB 8300 Linux filesystem Note that after running fdisk -l nothing happens, while after running gdisk the drive got mounted! > 7) what happens if you try as root instead of normal user? It found the drive OK, but did not open Konqueror, instead asked what to do (attachment). > Additionally, do you have d-feet installed on your computer?
