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.

I have the same (OSX -50) problem on my 3TB G-Drive w/Thunderbolt.
I use it with iTunes to hold a 1,5TB music library, playing, adding and editing.

So far my entire library has been wiped once. I have reformatted the drive, only to have the problem shortly after. At the reformat I named the drive "G-Drive w Thunderbolt" but shortly, a few hours, it was renamed to a8edsvee-daekw8qyyrt-uufaf (or something illegible like that) and the -50 error came back.

I am using a MacMini 1.4 8GB late 2014 with the latest Yosemite.

I have downloaded the firmware, but cannot use it as I have no firewire connection on the drive, nor on the MacMini, nor on my MacBook Air.

Please advice

Thanks

Henrik

Hi plafitracer,

There is no firmware update for the G-Drive Thunderbolt and have not usually seen a -50 on that model. Have you tried the drive on both tunderbolt and usb to see if the problem persists on both? If it works ok on usb then it is probably a faulty thunderbolt cable. If it works fine with USB send me a PM with the s/n and you shipping information and I should be able to send you a replacement cable.

Hi Dustin,

Thanks for your reply - I'll copy my library back to it and try again with USB.

With thunderbolt after the reformatting the second time due til -50 it suddenly changes its name from G-Drive with Thunderbolt to something like q67dhhert-43fertj74-fsr6we5-fsadfrbg - garbage at least...

I also have problems copying the G-Drive icon to it - it won't accept it.

Next

Return to G-DRIVE
