What does the plus sign after the blocks value exactly mean in the fdisk output? Some research reveals that it indicates that not all the blocks are included in the fdisk value. But what does this exactly mean? Kai -- Kai Sch?tzl, Berlin, Germany Get your web at Conactive Internet Services: http://www.conactive.com

But what does this exactly mean?IIRC, it means that the partition did not start/end on a cylinder boundary. I get these all the time when I manually configure partitions to get every last block used (not since "large" drives were about 500MB). As to loss, maybe yes. When you allocate using multipliers, (10GB, 100MB, etc.) the bytes per cylinder is used as a divisor. This *may* leave some part of a cylinder unused at the end. With todays drive sizes, even anal me doesn't worry about it anymore.> > Kai >HTH -- Bill

But what does this exactly mean?Those blocks are 1024 bytes each, so you'll see that "+" when the partition contains an odd number of 512-byte sectors. That's all it means. The root cause is that the usual pseudo-geometry used is 63 sectors/track and 255 heads, which results in a "cylinder" with an odd number of sectors. -- Bob Nichols "NOSPAM" is really part of my email address.
