    Just looked at Disk Utility and it tells me I have a drive which is S.M.A.R.T Status : Failing

    Also this message : The drive has a hardware problem that cannot be repaired.
    Back up as much of the data as possible and replace the disk.

    The drive still seems to be reading and writing OK, what on earth could be wrong with it ?

    There are many different S.M.A.R.T. attributes - which one(s) is(are) failing? What are the details?

    If you see a lot of "Reallocated sector" and "Pending bad block" failures, the drive is soon to be toast.

    I did a Verify Disk and it does a list of checks that all come back OK and it finishes with this message : The Volume XXXXX appears to be OK.

    I'm not an expert on this, but it sounds like the OS is doing a great job of keeping the file system intact even though the drive seems to be failing.

    Drives are pretty inexpensive these days. Don't risk your data. I would replace the drive.

    Thanks people, ordered a new one, it is only for storage so just have to move the stuff on it until the new one arrives.

    FYI, did you hit the "Info" button, when you have the disk highlighted? That will give you all the extra info about sectors, good/bad/reallocated.

    Sounds like replacing the drive is a great idea, so the above is just for grins and giggles.

    Get SMART

    What is "Verify Disk" - does that run the S.M.A.R.T. self-test or is it an OS-level utility?

    The disk maintains error logs and error statistics - look at those through S.M.A.R.T. for an accurate view of what's happened on the drive.

    Sorry, yes Verify Disk is just OS level being part of Disk Utility that comes with the Mac OS. Just downloading the S.M.A.R.T utility for Mac and checked with that. Got a BIG red FAILED and this -
    Reallocated Bad Sectors 4356.

    Just a Question - Since the drive is not a Boot Drive why did the OP use Disk Verify rather than Disk Repair? Yes, the disk is failing and should be replaced. But I'm puzzled by the use of Disk Verify rather than Disk Repair.

    Why puzzled ? Right hand side bottom in the Disk Utility has Verify Disk and Repair Disk, both when chosen gave the same result, Oh and I am here reading my thread why not direct your question towards me, people here do not know why I did what I did, anyway it did not matter both choices lead to the same result.

    ----------

    Just for the Grins n Giggles here is the result that the "Info" button gave me with the disk highlighted.

    Name : XXXX
    Type : Volume

    Disk Identifier : disk2s2
    Mount Point : /Volumes/XXXX
    File System : Mac OS Extended (Journaled)
    Connection Bus : SATA
    Device Tree : IODeviceTree:/PCI0@0/SATA@1F,2/PRT3@3/PMP@0
    Writable : Yes
    Universal Unique Identifier : 48CDEC36-50DC-3BC6-A01C-C57A8B9B468C
    Capacity : 2 TB (2,000,054,980,608 Bytes)
    Free Space : 1.53 TB (1,534,064,500,736 Bytes)
    Used : 465.99 GB (465,990,479,872 Bytes)
    Number of Files : 62,123
    Number of Folders : 917
    Owners Enabled : No
    Can Turn Owners Off : Yes
    Can Be Formatted : Yes
    Bootable : Yes
    Supports Journaling : Yes
    Journaled : Yes
    Disk Number : 2
    Partition Number : 2

    Which does read a bit strangely because I do not boot from it and it does not have two partitions.

    Sorry if I pissed you off:confused: The reason I asked the question is that Disk Verify is a passive test, it only reports errors. Disk Repair on the other hand has limited repair capability and sometime will repair a disk by mapping out bad sectors and etc. You may also want to consider Disk Warrior or Tech Tool Pro, they have more disc repair capability and can often times salvage a disk that Apple's Disk Repair can't. But, in any case, it's best to replace your offending drive. Again, didn't mean to incur your ire.

    Aslo, IIMU that all HDDs and SSDs have at least 2 partitions. One is the the EFI partition and the other the storage partition.

    No problem, thanks for the pointer towards Disk Warrior and Tech Tool Pro, and the info regarding the partitions :)

    replace the disk ASAP

    That's very bad news - the disk is clearly failing due to major problems.

    Even worse news will be if you look again and the number is climbing.

    The reason the OS utility didn't report errors was because the disk is fixing the problems - but if sectors are going bad at a high rate it will soon die.

    You're welcome.

    If the number of bad sectors is higher when you're done, please post the new number here.
