    My iMac has really slowed down over the past few days. I ran EtreCheck today to see if I could find out why. It found a MAJOR problem: Your iMac has an older, mechanical hard disk that appears to be failing. (Full report attached).

    Is it for sure a failing Hard Drive? I have time machine backups all the time, so I should have good backups. I am still under AppleCare. Will Apple replace the drive before it actually fails based on EtreCheck? What else do I need to check before making an appointment at a genius bar?

    EtreCheck version: 5.1 (5020)

    I believe this refers to SMART status. You can check this in disk utility

    or in System Information (about this mac, etc)

    If your smart status is something other than "verified", you may wish to read

    If EtreCheck had detected a SMART failure, it would have said so. EtreCheck is assuming your hard drive has failed because of this kind of performance:

    File system: 120.97 seconds (timed out)
    Write speed: 56 MB/s
    Read speed: 55 MB/s

    I don’t know why your hard drive is running so poorly. It may be because of the non-standard partitioning you have setup. It is difficult to see in this forum. EtreCheck is optimized for the new Apple Support Communities. If you want to post it here, you should probably wrap it in some kind of “pre” tag or something to get it to display with a monospaced font. If your indentations were showing up properly, then it would be more obvious.

    You have one of those tiny 28 GB SSDs fusion drives. That will speed up your booting, but not much else. But your Fusion drive seems to have been split up. Your SSD is fused with 300 GB of your mechanical hard drive. That fusion volume is formatted as HFS. I assume it has High Sierra or something installed on it. The remaining 700 GB of your mechanical hard drive is running APFS with Mojave.

    Even a plain-jane mechanical hard drive should have better performance than that. It may be that APFS is just really confused with this partitioning.

    EtreCheck thinks that you may have a Time Machine volume. Hopefully that is true. You need to wipe that machine, restore your original partitioning, recreate your Fusion drive, and reinstall Mojave. Apple will certainly not do anything based on an EtreCheck report, but they should be able to figure out this without it and do what is necessary to correct it. Just make sure to have a Time Machine backup before taking it in. You are definitely going to have to restore from it.

    Apple uses a version of TechTool Pro. If the drive has problems, they will show up. Since you are under AppleCare, get it to Apple to verify and repair as necessary.

    Have a Time Machine backup. If Apple replaces your drive, they will not save your data.

    It is quite possible for a SMART status of drive to be “verified” in Disk Utility while failing miserably. I have replaced over a hundred over the years.

    That is probably not your problem, though. You decided to partition your drive without having the slightest idea of what you are doing and no understanding of APFS. That is the only thing this report tells me but it’s screaming this.

    You need to put it back.
