Partition table lost on WD My Book 4TB
Posted: 26 May 2014, 12:17
Hi,
I bought a new external drive from WD (My Book 4TB). The short SMART test finished without any error.
I deleted all partitions and created a new GPT table as well as one large LUKS/ext4 volume. Here I ran into the first problem: gnome-disks did not let me create the volume using all available space (4001 GB) so I tried 4000 GB and it worked fine. I unmounted/mounted a number of times to make sure everything is fine and finally began transferring data to the drive. I unmounted and disconnected the drive and wanted to continue copying this morning. However, the disk now only shows "unallocated space".
The data I copied is not really critical (I still have most of it on another drive) but I would like to understand the problem. Any idea what could cause this mess?
In the case that TestDisk does not help (it is currently running but seems to take a long time), could anyone suggest further tools or tutorials to try?
