Now that the world has fsanalyze to see how fragmented their disks are when are we going to see a utility to unfragment them in place. The MS-DOS world has had the Norton SD(and others) for quite a while and I just got B.A.D for my Amiga a couple of weeks ago(highly reccomended I might add) but nothing for Un*x except to backup and restore. That just seems incredible especially for those of use with 40 Mb hard disks and 360Kb backup medium. Not really a starter. Surely some hardworking programmer has such a thing and would be willing to gain fame and fortune(doubtful) by giving it to the net. -- Jim Sanchez {sun,hplabs}!sun!sytek!syteke!jim OR Sytek Brussels mcvax!prlb2!sunbim!syteke!jim

The author of fsanalyze (sdti!mjy) has been working on such a program. Last I heard, it was going to be available for sale at reasonable prices. An unfragmented disk does make a big difference. -- Jon Zeeff zeeff@b-tech.ann-arbor.mi.us Ann Arbor, MI mailrus!b-tech!zeeff

I have a unfragmenter which is modified from the fsanalyze programs. It is, I think, bullet proof, but also slooow. I use it on my own system (uPort SYSV/386 3.0e) and have no problems (now ;-). I borrowed heavily from the fsanalyze sources, and really only wrote a small portion of code myself. The method I used will unfragment a file, but does NOT compact the disk (intentionally). I have it set up to allow the user to selectively unfragment files from a list which is generated by the fsanalyze code. It then attempts to make multiple copies of the file and selects the least fragmented. I am sure there is a better way (look through the free block list maybe?). Anyways, if anyone is interested in a copy of it, send me a message requesting it, or if someone tells me how, I can submit it to a group. NOTE: This program may be very SYSVish in my mods, I've never used BSD. brian -- Wm.

This may be old news to everyone or might not, I dunno. I modified the fsanalyze sources to unfragment a disk with user deciding whether it should even attempt a specific file or not. The method I used is to run a basically unmodified version of the fsanalyze, and keep a copy of it's list of fragmented files. I then at the users request will create multiple copies of a file on the disk, up to 10, and then keep the best one. (Least frags or if tie least distance). The program works very well, I think, it doesn't trash my disk (it did once ;-). It is probably very SYSVish since I have never used BSD. If anyone wants a copy, just email and ask, or tell me how/where to post it and I will. But be forewarned, it works great for my installation, but I make no promises. brian Wm.
