My 1TB LaCie Rugged THB decided it was a good idea to stop working all of a sudden. If I open it in disk util I sometimes see an actual name of a partition, but most likely it's not the real name.
In Terminal I tried:
diskutil list /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *251.0 GB disk0 1: EFI EFI 209.7 MB disk0s1 2: Apple_HFS Macintosh HD 140.0 GB disk0s2 3: Apple_Boot Recovery HD 650.0 MB disk0s3 4: Microsoft Basic Data BOOTCAMP 110.1 GB disk0s4 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: FDisk_partition_scheme *1.0 TB disk1 1: Apple_HFS 150.1 GB disk1s1 2: DOS_FAT_32 BAK_WIN 150.0 GB disk1s2 3: Apple_HFS 100.0 GB disk1s3 4: DOS_FAT_32 120.0 GB disk1s5 5: DOS_FAT_32 480.1 GB disk1s6
And then to unmount this:
$sudo diskutil unmountDisk force disk1
gave this: Forced unmount of disk1 failed: at least one volume could not be unmounted Than for each disk:
$sudo diskutil unmount force disk1sn
Always: disk1sn was already unmounted
Because I wasn't able to do anything with my external HDD I made a desperate attempt to erase everything on it, including unbackuped files, cause this used to be the backup plan. This was the try:
$ sudo diskutil eraseDisk JHFS+ DISK_VOLUME disk1 Started erase on disk1 Unmounting disk Error: -69888: Couldn't unmount disk
But it didn't work as well. If you have any idea to get the HDD working or even safe the files, I would be really grateful.
Almost forgot about this from Disk Utility:
Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
