Fragmented Sparse images
Authored by: hmelton on Feb 17, '03 04:36:02PM

While the hint works as advertised, and I am definitely using it, there is a comment in hdiutil's man page that warns about disk fragmentation while using sparse disk images. I assume that the sparseimage's file is locked into place on the real disk and won't move if you attempt to defrag the real disk. In addition, the nature of a sparse disk that grows on demand assures that it will be fragmented. None of these problems are killers since you can always copy the data to a normal disk image, delete the sparse and re-create it and move the data back for a less-fragmented version.
