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.

    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.

    With SSD a CLONE backup is essential.

    sparse disk image will do

    used Disk utility which found the SSD unrepairable

    was that from Disk Utility ( Repair Disk ) ??

    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.

    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 )
