/************************************************************************** * * initialize the disks comprising the array * * We want the spare disks to have regular row,col numbers so that we can * easily substitue a spare for a failed disk. But, the driver code assumes * throughout that the array contains numRow by numCol _non-spare_ disks, so * it's not clear how to fit in the spares. This is an unfortunate holdover * from raidSim. The quick and dirty fix is to make row zero bigger than the * rest, and put all the spares in it. This probably needs to get changed * eventually. * **************************************************************************/
