I have a 2008 MacPro 2.8 with 3 drives. (80 GB SSD, 320 GB HD and a 1TB Time Machine HD) The older Intel X-25 80 GB SSD containing Snow Leopard (upgraded from Leopard)  seems to have died. (Grey screen) I tried the usual resets, used Disk utility which found the SSD unrepairable (SMART: verifed) and used the Apple hardware test which came up with the 4HDD/11/40000004 :SATA (0,0) error.  The test ran twice with the same result.  Trying to reinstall the orginal Leopard from the install disk couldn't even find the SSD.

Has the SSD failed? I may just want to replace the older SSD with another, more reliable SSD. Any recommendations? Brand? SLC? MLC? eMLC? Would the Intel 313 series- 20 GB be too small? Smallest practical drive capacity (GB)?

Best way to achieve the swap? Can Time Machine be used to recover the OS? Is the OS recoverable from the older SSD?

I don't have a clone of my OS I'm afraid.

Mac Pro, Mac OS X (10.5.4)

    Check the warranty -- the Vendor may send you a replacement.




    In my opinion, when you use an SSD you need to do extra steps to make sure it does not fill up with the remnants of deleted files and choke.


    Disks of all types have always gotten in trouble when you get them nearly full. SSDs running as if they were magnetic drives do not understand when files have been deleted, and still have all that deleted data hanging around to cause congestion, slow responses, crashes, and quite possibly Drive Failure.


    What I have done for a while is to consolidate free space (which has NO speedup value on its own) and then immediately ERASE free space to Zeroes, giving the drive controller back all the blocks that had been tied up with old stale deleted data.


    The other alternative available now is to use a popular third-party Utility to enable TRIM, so that the drive can be notified when blocks are freed. This has been well received, but Apple has not tested it, and if you have a problem, you are on your own for support. It requires 10.6 to function.


    I do not think you have an unreliable drive. I think you have inadvertently beaten it to death.

    I am running a 30GB SSD in 10.6.8 with no big Applications, Tunes, Photos, or Videos. I will be retiring it soon because it is TOO SMALL.


    If buying new today, I would not buy smaller than about 128GB nominal size for a Boot Drive, and at least 256GB nominal size for an "everything" drive for a laptop. Even at 256GB, you will still eventually face having to archive some stuff off to another drive -- possibly an external that stays on your desk.

    Just re-checked my drives from disk utilty. The SSD shows 55.92 GB available from 74.21 capacity, so only 18.92 GB used. I was going to try a Time Machine back up, but want to proceed with caution. I wanted to be certain what I'm erasing if I re-install.

    I wasn't truly ready for this outcome, having no proper back-up, no Firewire cable to try Target mode, no external HD for backing up.

    I used disk utility to verify/repair disk-no luck. Tried reinstalling Leopard from the disk and the SSD drive doesn't even show up.

    From Apple support:



    When you test your Mac notebook using an SSD or Flash storage drive with Apple Hardware Test (AHT) diagnostics, you may encounter the following message if the test is looped multiple times:

    • 4HDD/11/40000000:SATA


    The alert is erroneous and generally takes multiple loops of Apple Hardware Test to induce.

    Before starting Apple Hardware Test, looping can be enabled or disabled by pressing the L key on the keyboard. If the message appears and there are also other issues with the computer that appear to be related to the solid state drive (SSD) or Flash storage drive, schedule an appointment at an Apple Retail Store or contact an Apple Service Provider.

    Still not sure if my SSD has a problem though...

    With SSD a CLONE backup is essential.

    sparse disk image will do


    TRIM Enabler

    Should I try reinstalling the OS from time machine or just replace the SSD? It is an Intel X-25 from early 2009.

    used Disk utility which found the SSD unrepairable

    was that from Disk Utility ( Repair Disk ) ??


    what was the exact error message ??

  • Lhotse8511 Level 1 (0 points)

    Running disk utility from the original Leopard install disk-1. When verifying the SSD the following error shows:


    Invalid record count

    Volume check failed.

    Error: Filesystem verify or repair failed.


    Repair disk is not available, but greyed out.



    I do see the Mount point showing not mounted.

    TRying Leopard installer doesn't even show the SSD boot drive as a destination...

  • Lhotse8511 Level 1 (0 points)

    On DU, the 3 HD's show up on the left side, but the 2nd listing for the SSD is greyed out now. In Restore, I had looked at the disk image for the SSD yesterday, now it is not available.

    I do not see evidence of Drive (Hardware) failure. The drive has a Directory (software) problem. You cannot do anything major to it unless/until you do one of the following:


    a) successfully repair the problem.

    You could try booting to the Installer/Utilitries DVD and waiting for the MenuBar to be drawn, then choosing Disk Utility from the menu. It may be willing to do more for you since you are booted from the DVD, not the drive under test. Otherwise, you would need to take a gamble that a third-party tool might repair it.)


    b) erase the drive, which deletes ALL the files on it.

    You should probably choose the option to Zero all data, one pass. Do not use Random data or multiple passes.


    In the long run, I suggest you install 10.6 and TRIM Enabler.

    I have booted from the install disk, the computer will not start from the boot SSD under any normal circumstances. When I start the computer normally, I get the Grey screen, a couple of progress bars, then the computer shuts off-every time. Opening DU from the install disk will not repair the drive, only giving the errors from verification reported in my previous posts. It only verifies to a point of error-no repair allowed.

    I am now ordering an OWC external drive case and will be using a WD black 1 TB drive in place of the Hitachi deskstar offered. This OWC enclosure comes with ProSoft data rescue 3, is this software any good? My SSD is currently unavailable, I assume it may repair via a disk install?

    If I were to replace the drive, which i have no problem in doing (not sure if I trust the aging Intel SSD) what SSD would you recommend? Is the OWC Mercury Enterprise using eMLC any good?

    I would erase the disk at this point, but I have data on there I can't get to right now-eg: PhotoMatix pro. How could I recover this data now, the SSD doesn't even show up during an attempt to re-install the OS. I am ordering a FireWire cable as well, maybe Target disk mode?

    I will definitely upgrade to Snow Leopard again, we were  using it when the system crashed. I am using the original Leopard install disk to access DU. I will also use Trim enabler.

    Are SSD's incompatible with Mac's more than Window's-based computers?

    I could just use a regular HD again for the Boot drive...

    Your SSD drive has Directory corruption. This can happen due to "crazy software" or programs crashing or bad shutdowns or "just because". It is NOT a Hardware failure. The drive itself is fine, the Directory (scoreboard of what files are where) has a tiny but critical scramble in it.


    Data Rescue 3 is not a bad program, but It is NOT a repair program. It will attempt to copy files off a wounded drive to another drive. The problem with this is that sometimes the filenames are not recoverable, and you get a huge pile of files that have to be opened and inspected individually.


    The most popular third-party Directory-Repair program is Disk Warrior, by Alsoft. It combs through the areas normally reserved for Directories and tries to put the pieces back together to build a new Directory from the fragments of the old one. It then shows you a before and after presentation. ONLY If you approve, it will replace the damaged Directory with the new one it has built.


    Where is your 10.6 Snow Leopard DVD? It may be better at repairing Directory flaws than Leopard. Boot from the 10.6 DVD and attempt the ( Repair Disk )
