Can all levels of RAID recover data if a drive fails?

<p class=”” data-start=”70″ data-end=”206″>I have a flatbed server with four hard drives set up in a RAID configuration. One of the drives is freezing and has become unresponsive.</p>
<p class=”” data-start=”208″ data-end=”279″>I was told that if one drive fails, the whole array could stop working.</p>
<p class=”” data-start=”281″ data-end=”402″>Is there any way to clone the bad drive and get the system to boot, or will it keep giving me issues no matter what I do?</p>
