I just was wondering what would happen immediately after a hdd failure occurs in a hardware raid 1 array? Will the pc continue to work with only one hdd?

Yes, the array will continue to operate so long as at least one member drive is operational.
RAID 1
RAID 1 consists of an exact copy (or mirror) of a set of data on two or more disks; a classic RAID 1 mirrored pair contains two disks. This configuration offers no parity, striping, or spanning of disk space across multiple disks, since the data is mirrored on all disks belonging to the array, and the array can only be as big as the smallest member disk. This layout is useful when read performance or reliability is more important than write performance or the resulting data storage capacity.
The array will continue to operate so long as at least one member drive is operational.

I would hope that immediately after, you would get a disk failure alert. – Andrew Morton – 2016-05-29T17:41:06.180
