BogG,
thanks; i deleted non-dos partition; then extended partition; but the message says i cannot delete extended part while logical drives exist. so i tried to delete logical drives in extended dos partition; the message says: "all logical drives ... have been deleted"!
using the display funtion, i see only one partition left: extended dos. do i delete this?
i see no primary partitiion listed, strangely.

one further clarification. you said, "repartion using fdisk only, and format with format tool like you did before." are you telling to format using Win2k professional (which is my os) or Partition Magic 7.0?
thanks also for suggestion on partition sizes; what happened last time was that it never came out exactly.
