You then slice and partition the disk and build file systems. This is all overhead that is not accounted to a single partition. Also, df reports in "1K-blocks". this means 1024 bytes, not 1000. Disk manufacturers have long used 1 GB = 1,000,000,000 bytes, not 1,024,000,000 bytes. This means that your 46 GB disk is actually closer to 45 GB (at very best) and may, depending on rounding, be closer to 44 GB which is about what the partitions total. When you add file system overhead, I think this looks about right. R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
