Wow. All I can say is what a vast improvement.

I booted with the OS 9.1 G$ PowerBook CD (The only CD I have that boots my iMac into Classic) and formatted the drive and selected "zero all data" and waited and waited.....*6 months later* and waiting and waiting. j/k It took about 3 hours or so.

So the hard disk is 100% zeroes and I installed Classic and OS X, and now my machine is a speed demon, I can't believe how fast it is. I've never had it this fast.

I just got my second wind.

Why would zeroing the hard drive make it faster?

Fresh clean slate all zeros. Typically when users erase hard disks, the data isn't gone, merely ignored. Then new data is overwritten. A bit messier yes, but I prefer the fresh installs, less chance of fragmentation.

As long as you backup everything on the disk it's safe. I used Mac OS 9 CD because I know it's Disk Setup has the option to zero all data, unsure if the OS X version does or not.

You will notice a speed bump though, it's faster. Although you can defrag a hard disk, I don't like to as the last time I did, it corrupted my Quake 3 Install..so I was worried about other files as well.

There is an article online as well how you can hack Mac OS X to use a dedicated swap partition as well which increases speed as well since the partition is located on the outer disk tracks and never changes. (Outer disc tracks are larger in size, hence one revolution can provide more access to data then the inner circles of the drive which require more spins to locate data due to narrowing size of the plates) This hack also reduces fragmentation of the swap files.

heh, I might just do that, if/when i can go to granpa's house, I'll back up the iMac and try it with my panther install CDs.

I'm not sure how fast panther'll go though, so I might have to end up putting Jaggie back on there

Shouldn't really make a difference as long as disk is reformatted, but if you want to take the time.

Whoa -- zeroing all data has no effect on performance compared with a regular, quick-n-dirty reformat. Once the OS sees the disk as empty, it writes new data overtop of it. And whether it's all zeros or a random mix of ones and zeros is completely irrelevant for performance.

The reason for the improved performance is that a clean installation on a reformatted drive puts all the files -- in particular, often-accessed System-related files -- in one place, at the "beginning" of the hard drive. This increases performance (a) because the files are closest to the drive head, and (b) because the files are all close to each other.

So what you've really done is defragment the drive, and the files on it.

You can accomplish the same thing by using a defragger, or more simply by doing a regular, two-second reformat followed by a reinstall of the OS. In fact, to make it even quicker, you can copy the existing System Folder to another HD, reformat the primary HD, and then just copy the System Folder back onto the primary HD. All the files will now be defragmented and clustered together.

Defrag tools are messy. I like precision. I like the thought of all zeroes, plus any sensitive data is a litle more obscure too. :)

I prefer to zero the drive when ever possible. I have ran into times where something gets left in the boot sector and screws with things. It takes a little longer but it is better than chasing ghosts.

Humm… I try to avoid all of this
[Im afraid my stupid old HDs will die… which makes me think I ought to back up again… but our stupid copy of retrospect is too old to see ATA CD burners]

If I open my window all the bugs will get in…That's just one more reason to use a Mac!

Avoiding having to zero a hard drive, by just having to replace it? that's weird

Y'all are talking about defrag programs, but what defrag program even exists for MacOS and MacOS X? I have heard and seen of none that are free, like MS' defrag program with windows.

Norton System Works 3 does defrag and it's not free.

Norton: "You say we did a poor job defragging your system?"

Bruce Willis: "No, I said you did a piss poor job. You got your engine all backwards. Let me guess your corrupting data and can't figure out why? That's because your brains are all wrong Mr. Wizard."

;-) Like I said, it's a piss poor job of defraging.

I've heard that *NIX doesn't really defrag too good. It's better to just reformat/restore.Go to Top of Page
