[comp.sys.mac] streamlining a fragmented HD

mjschmel@phoenix.Princeton.EDU (Michael J. Schmelzer) (04/27/88)

My 20 Meg HD sounds like it's thrashing around a lot on startup
and such. Since my disk is pretty full, I suspect that several files
like my startupScreen and some INITs are fragmented.

In fact, I think that much of my HD is fragmented.

Has anyone encountered/dealt with this problem? I'm aware of a product
called DiskExpress that supposedly "de-fragments" your disk and makes
all the files contiguous.

But I'd rather not shell out $$$ for something that I can probably do
myself with some elbow grease (and patience.)

Before I take the big step and "reconstuct" my disk, I'd like to know
1) If I'm wasting my time: It wouldn't work anyway.
2) Any tips about how best to go about it.
3) How big a job it really is (if you've done it)
and finally,
4) Anything I missed.

Thanks a lot!!!

vendors should supply decent software utilities with their hardware - or be
forced out of business (they also should use quality parts , provide support,
arrange for quick repairs, and know what they are doing, in general - but that
is another story) ....

no hard-disk owner should be without a disk-backup utility, a de-fragmenting
utility, an analyze-and-repair utility, ... and probably several others.
because when you need them - you need/want them NOW - and, in the case of
a broken disk and a repair program, buying it later forces you to learn the
use of the utility at the worst possible time !

such programs exist, are available to vendors at a reasonable license fee,
could be made available to the disk-purchasor adding relatively little to
the cost of the hard-disk ..... etc, etc !!!

De-fragmenting utilities make assumptions about how the filesystem stores
blocks on the disk that might not be safe to make.  The only people who
should be writting de-fragmenting utilites are Apple.

Michael,

Two ways to unfragment a HD:

1) Use a disk optimizer, such as DiskExpress or PowerUp.  But make sure that
   you backup first.

2) Do a complete backup, reformat, and restore.  SuperMac Software's DiskFit
   will allow you to unfragment a HD by this procedure.  SuperMac also provides
   a DataFrame version of DiskFit to purchasers of any DataFrame/XP HD.
