[Bug 42065] Re: installer: confusion about partition sizes (1000 vs. 1024 issue)

[Sunding Wei]

I hate partman by doing this way. MB should always be 1024KB in computer
world, not marketing world. I have this issue with latest Ubuntu 14.04.

Title:
  installer: confusion about partition sizes (1000 vs. 1024 issue)

Status in “partman-base” package in Ubuntu:
  Confirmed

Bug description:
  If I enter "64m" as the size of the partition to be created, it will
  correctly create a 64MB (MB=1024^2 bytes, "real MB") partition. But in
  the partition list it gets displayed as "65.8 MB" (MB=1000^2,
  "salesman MB"). This is confusing.

  Please use 1024-based sizes, since it's what administrators are used to and what resembles the internal structure (512Byte sectors, n-bit block addressing) best. 1000-based sizes are mostly a creation of "marketing experts" to make the devices seem larger than they really are.
  A note about this difference in the partition manager could inform novice users why their HD is smaller than expected.
