    Disk Warrior is by far and away the best disk utility available. If

    all Mac users should own a copy.

    When you talk of reinstalling, do you mean you've erased the hard drive
    and started over? If so, then that pretty much rules out software
    problems, since you're started with a new directory each time, and it
    does look like the drive should be replaced, regardless of what the
    people at the repair shop tell you.

    Whoa! There's no indication that they've run Disk Warrior, so at this
    point we can't rule out directory problems.

    He stated this has happened 3 times and the two previous times the drive
    had been wiped. Wiping the drive would have resolved the directory
    problem for that incident. If a drive develops the same directory error
    three times running, an error that cannot be resolved by Apple's Disk
    First Aid, I think we can start looking for hardware issues.

    Oh, I certainly agree with you, but in his original post he gave no
    indication he had erased the drive at any point. I did subsequently
    find that info in a followup of his.

    Hmm, suddenly my brain is opening...we re-installed the first
    time...pretty sure we erased, not just a reinstall. The place we took
    it to installed 10.2, backing up the previous stuff to a folder - is
    the drive being erased in this case ?

    No; this is just a reinstall.

    If they had erased the drive, the only thing that would have been on the drive when you got it back would have been the system--all your folders, programs, and data would have been gone.

    If a disk's directory has a problem, and you reinstall without fixing that problem, you don't do yourself any favors--and you may, in fact, make the problem worse.

    Just got word that the hard drive needs replacing. Where we are,
    the cheapest new drive we can buy is $ 149 (with tax approx $ 170).
    My daughter isn't too trusting of anything more she'll have to pay for
    with the computer. This is similar

    http://www.everymac.com/systems/apple/imac/stats/imac_400_indigo.html

    though she has 128 MB RAM and a 20 GB hard drive. She's not sure
    of the present value if she would want to sell after the new drive, so
    we're not sure what the next step is.

    Thanks for your help and for taking the time to respond and
    discuss, much appreciated.

    Given that you can walk into any CompUSA/BestBuy/etc and get a drive,
    why not just buy a 40GB IDE drive that commonly goes on sale for $30
    at one of those local merchants? Fry's has it for $29 right now.

    $150 for a drive is outrageous unless it's a 200GB monstrosity, but I
    doubt the iMac would support it.

    $149 for a 20 GB hard drive??! They're readily available for around
    US$60, which as of today is only $80 Canadian. If that price doesn't
    include the installation, you're being ripped off.

    Any idea if this system would be able to use a Quantum Fireball
    LM15 720 RPM drive ? The guy at the shop said it should be a 5400 RPM
    drive or under, does that make sense ? The $ 149 was for a 40 GB
    drive, sorry about that. I have the Quantum available to use, but am
    not sure if the system will use it, sure hope so.

    I'm in Canada, the best price I have seen around where I live is a

    30 Gb 2Mb 7200 Rpm Maxtor Ata 133 for $ 86, we just opened a
    BestBuy here, haven't gotten there yet, the
    http://www.bestbuycanada.ca/ website doesn't have any prices.

    Agreed. At our local outlet, a 40GB Maxtor 5400 rpm drive is $72.19 (Fireball3), while the equivalent 7200 rpm drive (DiamondMax Plus8) is
    $74.55

    Even converting to Canadian prices that is a heck of a lot cheaper than
    what Alvin was quoted.

    There are some cheaper places in Canada to buy equipment, but I
    usually get green when I see prices like that. Even for blank CDR
    media, I'm usually there if I can get 50 for $ 25, the lowest I have
    seen Japanese Taiyo Yudens is $ 35 for 50. I know of someone who has
    a new (oem ?) 30 GB drive for $ 76 (2 MB cache), lowest I have seen.
    The original price quoted to me was from the only all - Mac store in
    our city, prices are usually higher there. I may be able to get a
    used 20 GB drive (7200 rpm) that I could put in the Imac. Anyone like
    to comment on how easy / hard it is to open the case and replace the
    drive ? Or would that would be like anything else, seems daunting but
    when you do it (after the blue in the air clears) it was much easier
    than expected ? Looking at a couple of online sites here, they don't
    even list a 5400 rpm drive.

    I'm assuming we are talking a colorful iMac? I've done drive
    replacements on the original Bondi blue and later slot loading machines.
    The job is finicky but not really hard - until it comes to putting the
    computer back together again.

    Use Google to do a search on iMac hard drive replacement. You'll find
    several sites that include pictures of the job.

    Basically, with the iMac sitting on its screen (put a couple towels down
    on the work surface) take the case apart, disconnect a couple wires, and
    pull the innards (don't you like technical terms?) up and out of the
    plastic case. Pay very very close attention to how the innards are
    arranged because you have to get them back that way!! If you have a
    digital camera, have some one taking pictures over your shoulder as you
    lift it out. Seriously, getting it back in is the hardest part of the
    job.

    After lifing out the innards you take off a wire cage, remove the drive
    power cable and IDE cable, disconnect the drive, plug in the new drive,
    and put it all back together again. If you have a slot loading machine
    you'll immediately get to see if you got the innards lined up right.
    Does the boot CD go in? Dang it!! Take appart and reseat!

    Anyway, boot the computer with the system CD, use Disk Utilities to
    format the drive and reinstall the OS.

    The first time I did this it took me 45 minutes - I took my time paying
    close attention and drawing pictures as I took it apart. And it took me
    about 10 minutes to get the drive/logic board assembly mounted into the
    case properly. The second one took me 10 minutes.
