box reboot after hdd write error

[claudiu vasadi]

Hello fellas,

My system is a 8.0-RELEASE with 6 hdd's. 2 days ago I had some power
failures and 2 disks were affected. These 2 hdd;s are connected to "atapci0:
<SiI 3512 SATA150 controller> port
0xd000-0xd007,0xd100-0xd103,0xd200-0xd207,0xd300-0xd303,0xd400-0xd40f mem
0xfa4a0000-0xfa4a01ff irq 12 at device 4.0 on pci2" s-ata controller. Before
the power surge, the disks were operating normally. I use them for storage,
therefore no system data is kept on them.

The issue here is that after the write failure, the box reboots. Up to this
point I cannot figure out why it reboots, since the disks contain no
"relevant" data (from a OS point of view).

Do you think it's normal for an OS to reboot if 2 disks have write errors ?
even more so, if the disks have no OS files on them ?
