Take the 2-minute tour ×  I have an Ubuntu 13.04 server. Today I
found the box had crashed. I restarted it, and now every single
hard drive's partition table is missing. (1 SSD for /boot, /,
and 3 2TB drives for RAID).  I have the SSD connected to a
laptop VIA USB->SATA cable, and sure enough, the partition table
is missing. This tells me that the Motherboard / SATA controller
/ software actually broke the drives, not that they just can't
be read correctly.  Something similar happened to only the SSD a
few months ago, and I was forced to just re-partition it.  How
the heck could his have happened? Bad Motherboard or SATA
controller?  share|improve this question  closed as too broad by

the drives are not supposed to have a partition table. Can you
elaborate more on the type of RAID (hardware/software, etc.)? Be
sure to consider the possibility that the drives are not being
