evenly divisible by the block count, as many full blocks as possible are transferred, followed by a final, partial block transfer. The Partial block transfer shall be for n sectors, where n = residue of {Sector Count / (Sector Count per Block)} Disk errors encountered during WRITE MULTIPLE EXT commands are posted after the attempted disk write of the block or partial block transferred. The write operation ends with the sector in error, regardless of the position in the block. Subsequent blocks are not transferred in the event of an error. Interrupts are generated when DRQ is set at the beginning of transfer of each block, except first block. 7.5.63.
