[Disksim-users] Disksim-users Digest, Vol 67, Issue 15

[葉柏成]

Hi,

It really works!! Including Number of parallel units = 1,2,4
But original should be "tmp->blkno = blkno"; not "tmp->blkno = tmp->blkno;"
 Thanks anyway. :D
Now I have a new problem about saturation msg while Plane block mapping =
simple concatenation in postmark trace
I will try first, thank you very much.
