What does dmesg say? Did you get read error on one of the remaining 3 drives? Then you need to look into the archives to use dd_rescue to get as much data off of that drive as possible, and try again.

It would also help if you provided what kernel version and mdadm version you're using.

Before you try again, also do this:

for x in /sys/block/sd[a-z] ; do
        echo 180  > $x/device/timeout
done

This makes sure the kernel will not kick a drive that might take long to respond due to read errors.
