    My G4 has an occasional chirping sound. I went through the steps to troubleshoot in this AppleCare Knowledge Base document. I was able to stop the chirp by removing my MacGuru's bought IBM 120GB ATA drive.

    Do I have a bad drive?

    What's the next step?

    When I searched Knowledge Base on "drive setup" and "low level" it outlined how to run a Test for bad blocks. Basically Test is not as thorough as low level's "zero all" which will read-write to every sector and block and remap bad blocks. I've heard that just running Disk Warrior has helped a couple times - always Step #2 (step 1 is BACKUP).

    If there isn't a hardware or firmware problem (Sonnet Tempo with buggy firmware or something), and the cables and power adapter are not an issue (sometimes you won't know unless you have a known good ATA cable to try), and Disk Warrior doesn't resolve the problem, then initialize or initialize with option to zero all data.

    now, some drives do a 'self-test' (IBM's Ultrastar SCSI models) every nn minutes or the drive parks the head. There are even sound bites at IBM and other places of what is normal and what is not - someone posted theirs to .Mac homepage for others to listen to. Some models more so than others. If you have a 120GXP, I'd be surprised. The 75GXP (30/45/75GB) had very high failure rate. 60GXP was better. I think the 120GXP (40/60/80/120) are soliid.

    when I did have a drive failure and it wouldn't initialize and kept failing, I contacted IBM, asked for RMA via web, that was a Thursday, and Monday 10 AM there was a new drive at my door and a box to send back the old drive. Very good service.

    StorageReview has news on the latest WD 8MB Special Edition models which is very popular. I think the IBM 180GXP will also be a winner but it isn't shipping yet. Same for Seagate ATA V Barracuda - those are my favorite IDE drive choices. With IDE, I always keep a spare on hand and try to pop it in and put a current backup on it every couple weeks besides my normal backup(s).

    Greg,

    I ran DiskWarrior twice (on both master and slave) and I still get a chirp. I will backup this weekend and run tests/initialize as you suggest. The drive I have is the only IBM 120GB ATA MacGuru sold--don't know the model number right now (at work).

    Thanks,
    Jesse

    My QS867 chirped when I changed the memory in it (went from 3 128Mb to 3 512Mb DIMMs). Don't know why but the first time I started it up after the memory swap it chirped a couple of times than came right up. I hasn't chirped since then. Weird.
