Internal HD Disappeared

Sumleilmus · 01-28-2013, 11:56 PM

Last night, without warning, the bay 2 Samsung 1.5 TB HD on my MacPro disappeared, leaving me with the red warning that I had "disconnected" it too abruptly.

Not a peep from SmartReporter was to be found.

The machine was running a 6 or so hour job, so reboot was postponed until 12 or so hours later. This is a new one for me. I have had external drives connected through USB hubs, or eSATA PCIe cards do this, not always with clear significance or sequelae…

Should I just lay low and see if it happens again? Should I make plans to migrate it to the pile of "can I really ever trust you again" hard drives?

(Ha ha, of course it's an accursed triple boot drive with partitions for Mtn Lion, Snow Leopard, & Windows 7 Bootcamp – but not the same one that was giving me trouble last week on another machine.

I finally found this in Console.app SYSTEM LOG QUERIES All Messages:

I'm not sure how to interpret this. Suggestions?

Could well be a corrupted Directory (HFS) a job for Diskwarrior to fix.
Is disk utility reporting any issues with any of Partitions ?

Are there any nasty sounds coming from drive ?
Take drive out and seat in another bay and test.

From memory I think all your backups are in order though but these things can point to a drive going bad too. SMART is so overrated.....often only telling you that drive HAS failed not failing ;-)

The disk has 3 partitions (really 4, but the first is EFI). The last is Bootcamp, the one before it is Snow Leopard, and those two are almost always unmounted. They were unmounted at the time that not only the first partition, usually mounted, disappeared with an announcement the whole disk had disappeared. I could not find it on the SATA bus in System Information, diskutil list could not see it, nor could Finder or DiskUtility. I was in the room, but not looking at the display.

After shutdown for about an hour, followed by powerup, the disk reappeared. I ran DiskWarrior4.4 on the two JHFS+ volumes. It ran very very slowly on one, but completed. On the other it found a bunch of text encoding errors that looked to me like traditional Chinese. I then ran DiskUtility First Aid on the partition map and then on all three volumes. No errors reported.

Now I wait and watch.

Ugg You might want to relegate the drive for scratch disk type work not data.

I recently lost drive/s temporarily to a sata cable gone bad that I had not touched for 6 weeks. Drives were fine when placed in enclosures. Ordered a new cable for my Macbook Pro. Not uncommon I found out. Probably less common with heavier cables in Mac Pro then ribbon cables in Macbook Pro.
