While booting, linux displays this:
SCSI device sda: hdwr sector= 512 bytes. Sectors= 8388608 [4096 MB] [4.1 GB]
which I believe to be untrue, because 4096 MB are exactly 4 GB.
With the patch below, it displays the corret result:
SCSI device sda: hdwr sector= 512 bytes. Sectors= 8388608 [4096 MB] [4.0 GB]
The GB are rounded, which was also in the original code, so my second disk
reports
SCSI device sdb: hdwr sector= 512 bytes. Sectors= 2031554 [991 MB] [1.0 GB]
although it has a little bit less than 1GB, but 0.9GB would be "wronger"
