One of my harddrives is failing  SMART check and needs to be replaced. Its the one I keep my iTunes files on and it is a 1.5TB Drive. I'd like to get my files off the drive before it dies completely.

  I've been looking at the 3 and 4 TB dives as replacements. I've been reading comments about 3TB Drives having problems but haven't found anything specific. WHat's the latest? I'd really like to go with a bigger drive for the storage space but I don't want to add a problem.

Any suggestions?

ALSO Should a large drive be partitioned above a certain size or is that "old school?"


Mac Pro (Early 2009), OS X Mavericks (10.9.1), been with Apple since my LC in 1987

    The very large drive you seek should be in an external enclosure, and you should be using it for backups.

     

    Then replace the one with Bad SMART Status and restore from your Backups.

     

    There has been a bug in 10.8.4, 10.8.5, and 10.9.0 that precludes proper Erasing of a new Internal Drive. We have no solid reports of it being fixed yet.

    I'm sorry to hear that Grant or anyone else has been having trouble with their machine.  I've had no problems whatsoever with partitioning or erasing any 3TB or 4TB drive in my Mac Pro 4,1 running under Mountain Lion (10.8) or Mavericks (10.9).  I do a fair amount of system testing on things, so data gets moved around quite a bit, drives get partitioned and reformatted fairly regularly.

     

    Currently I'm using a single 4TB drive, partitioned as one big drive, to store my iTunes library/media.  Previously, I'd had the drive partitioned as 1TB/3TB, and 500GB/3.5TB.  I have another 4TB drive currently with 3 partitions, and a 3TB drive in a single partition.  Neither Disk Utility nor Drive Genius have ever reported a problem with either drive.

     

    I had a friend with a Mac Pro 3,1 who did have a problem using a 3TB drive once, but if I remember correctly he resolved the problem by disconnecting all his external drives (FW & USB) and rebooting.

     

    The advice I'd offer is to avoid the WD green drives (or other manufacturer's equivalent) AT ALL COSTS.  They're great drives for casual use, but aren't really suited to big workstations or server hardware.  I'm a fan of Western Digital's red drives (or other manufacturer's equivalent) for an iTunes media library.  Those drives are designed for use in servers and network attach storage, and while they're not the fastest drives out there they're fast enough for serving up movies and music (on either the machine locally or over the network to AppleTV's, etc).

    your drive has failed and should not be mounted or used at all until you can clone, or use Data Rescue 3.

     

    I would pick up a couple 2TB Seagate Constellation drives to replace the 1.5TB drive that failed. And look for a largest size drive for TimeMachine.

     

    Also, SoftRAID 4 can take a drive and scan for and map out bad sectors. There may be other programs also w/o a destructive long format.

     

    The issues with 10.8.4 and above with drives of 2.5TB and larger did not seem to care whether it was enterprise Seagate or not. Issues with WD Green have been around longer and seem to be 3TB models and maybe specific models but not related to the 10.8.4 DU issues. Reconfirmed by others that have had trouble with Mavericks.

    Be sure to check out the discussion of bottom mounting holes on large WDC 3+1/2" drives nearby:

    I've got a MacPro 6-core (MacPro5,1), was running 10.8.5, installed an HGST 4TB hard drive in one of the internal bays, use Disk Utility to partition and format it, then ML would no longer recognize it.  I read about the drive bug, so I "reset" my OS back to 10.8.2 and now everything is fine.  From what I've read,the "bug" was introduced in 10.8.3, so I'm now hesitant to move back up.

    This was reported to Apple, and a User here reported back they confirmed it as a Bug. There is no problem initializing in an External enclosure, and no problem with earlier versions as you have verified. [seeing the problem in 10.8.3 moves its creation back one version from what we knew about.]

     

    Subsequent Users have confirmed that once the drive is Erased (using a non-affected version or enclosure) there is no problem with Partitioning, Re-partitioning or Using the drive, even in the affected versions of Mac OS X.

    OK, let me be SURE that I understand this.  I have this 4TB drive initialized, formatted, and partitioned in 10.8.2 using an internal drive bay.  So now, IF I understand what you're saying, I can upgrade to 10.8.5 and continue to use this disk, EVEN if I have to erase, re-format/repartition - is THIS correct?

     

    Or do I have to save a backup of my 10.8.2 system in case I ever have to re-do this drive?

    Not if you attempt to ERASE. Then you are screwed.

     

    Partition is OK, according to a User who was simply not in the habit of Erasing, and had no issues whatsoever.

    OK, thanks.  I do have external drive cabinets if needed to redo this drive or set up any new drives but I'm going to make a backup of the 10.8.2 setup anyway just to have it.  That's the nice thing about the MacPro - all of the internal drive bays plus I've got 2 PCIe cards installed, giving me 4 eSATA connections and 2 USB3 ports.  I can connect just about anything....

    Thanks, I never would have guessed drives seem to have gone just enough above the orginal sizes as to no longer fit on drive sled and align properly being the issue.
