Error -50 OSX

Postby pepo » Jul 5th, '13, 06:37

Hi,

I've been working with a G-Drive of 2TB that keeps getting an error -50 code in Mac OSX. When we get this code we cannot write to disk anymore. Also the disk will not properly eject as you have to use 'force eject' to unmount the disk. After you remount the drive everything is okay for like 6 hours and then the error -50 kicks in again and you can't use the disk anymore.

We're actually using two of these drives on two different machines with different OS's. One is Lion OS, I think 10.7.5 and the one Mountain Lion 10.8.4. We connect them via Firewire 800 cause we are editing video with them.

Also the drives go to sleep after a while, no matter what is chosen in the OS system settings.

Any idea how to solve this?

Hi,

Thanks for your post. A -50 error is a general I/O error that is caused by an recent Apple update. There is a firmware fix being developed, and should be available soon. Please let me know if you have any questions.

Hi Jerry,

Yes the firmware update is available from the downloads section of our site. You can find the update at the following link. Please make sure the drive being updated it the only drive attached when you run the updater after installing it to the computer. While the update does not format the drive itself we recommend backing up the drive if not already in case something interrupts the firmware update.

I have this issue. I just applied the most recent firmware update (App says Ver. 0.4 Tuesday, June 17, 2014 at 2:46 AM) to very new 4TB G-Drive. Then I reset NVRAM and SMC controller on my late 2011 17" MBP on 10.9.4.

So, I still have this issue and can not copy. "The operation can’t be completed because an unexpected error occurred (error code -50)". It just occurs on one of the two partitions, but the affected partition has to be Force Ejected to unmount.

The drive reports as updated when I run the updater app. Also, I just realized this thread has been going for a year, so the Apple update mentioned is ancient. What's going on here? Do I need to return this drive?

Please solve this ASAP.
Thanks,
Lance Lipman

Hi Lance,

If the problem is happening on only one of the two partitions and is always happening the issue is logical and isolated to that partition. If it were the firmware issue or a physical problem you would have trouble with both partitions. Also if it was the firmware issue you would only have the trouble after the drive has been idle for more than 10 minutes. I suggest running a verify disk on that partition in disk utility and if it sees no issues I suggest backing up the partition and formatting it.

Thanks Dustin. The problem was indeed, only happening on that partition and only after inactivity. I bit the bullet and reformatted with a single partition. So far, so good. I will know for sure later and will report back.
