I think whatever went wrong began when Linux (Gnome Ubuntu) crashed again (as it does all the time). Because the system was then entirely unresponsive in the GUI, it was shut down from the power switch. Clearly a bad idea. On restart one of the partitions has vanished. The PC has 5 data partitions. The boot drive (an ssd) plus 4 more of 2 to 3 TB each (total 10TB of hdd). All 5 are NTFS - because all 5 were originally formatted for Windows.
Please help by answering my questions:
Q1: What is the best and safest way to shut down a Linux PC if the GUI crashes?
Q2: Which O/S is least likely to suffer these accidents of vanishing partitions?, and is written to allow recovery from such disasters.
Q3: What can I do, if anything, to recover my partition?, and further analyze the issue?
Q4: What tutorials or books can be recommended from the P.O.V. of building a reliable workstation which resists crashes.
Q5: What kind of Linux, or other O/S is safest against this kind of (assume software) fault?
