Disk Drive ejecting itself

Is that still working for you? I just tried it... no go :/

Is anyone from Apple paying attention to this???

No. Apple is not here as it states in the TOU.

I meant are they paying attention to the issue - not the thread. I know several people have submitted feedback... We just need a wink from apple saying they are aware of it. That's all I expect. Apple's entire support structure is completely broken - from the genius bar up.

All my USB external hard drives quit by themselves time by time, and couldn't cope files to them. "not ejected properly" warning came up all the time whenever I wanted to copy something to them. They were all used with the old iMac. But one drive was formatted with the new Mac Pro. They all have their own power supply, not used as Time Machine backup.

Running 10.6.6 on Mac Pro.

But Allan...

According to the TOU, there ARE Apple employees (including administrators, hosts and volunteer employees) that DO monitor and participate in these forums. I'm sure it is encouraged by the company.

There are sixteen pages here in this thread alone concerning a very possible glitch in the OS occuring with external drives. One would hope someone at Apple would be interested enough in the problem to forward a link to the discussion to the right folks there. It doesn't appear so, since the thread goes back to day one of snow leopard...and no apparent fix yet.

Is nobody up there having this same problem? They all couldn't have been that smart not to have upgraded to 10.6.

Folks,

I have sent some Console logs and the results of a Capture Data run to an Apple Senior Advisor who said she would pass them on to Apple engineers and get back to me in 4 days or so, which should be this week.

I gave her the link to this discussion and she said she took a look at it, so I presume she has passed it on to the engineers. By the way, like all the other Apple people I have talked with about this issue, she said she had not heard about this problem until I told her about it.

I'll report what transpires.

Thank you onemac, you are a saint. Hopefully your St. Valentine.

We'll see...

I have the same problem with two of my drobos............

I had the exact same problem.

I bought a brand-new Samsung S2 Portable 1Tb 2.5" USB3.0 external harddisk and after some seconds backupping in Time Machine I got the eject-error. After reading this discussion I swapped this drive for a Lacie Rikiki 1Tb 2.5" USB2.0 external harddisk and this works like a charm!

I guess this has something to do with the power supply; the disk needs more current than the USB-port can supply. I tried this disk on my AC Ryan mediaplayer and had the exact eject-problem.

On my Windows7 laptop however, the Samsung disk worked without any problem. 2x 5 hours of non-stop data transmission and not a single eject-error. Guess this laptop can deliver more current.

Maybe it's a good idea to make a list of failing external drives?

If anyone is interested, I created a list for failing external drives. Feel free to add your (not) working drive on OSX:

I just got similar problem with my external HDD WD MyBook 2 TB on my iMac. This WD using external power source and still less than two months from the date I bought it. Today suddenly in my screen appear this message:
http://img87.imageshack.us/img87/1889/screenshot20110219at233.png
"This disk was not ejected properly. ....etc"
I didn't touch the HDD nor the USB cable.

The problem didn't stop there, now my WD its very hard to detect ;_;. At first my Mac able detect all 3 partition. But it had problem with write/read speed. Very slow and I've tested it with AJA benchmark. Only reach less than 1,5 MB/s.

After trying some shutdown, restart and plug into different USB slot, at first I think I've solved the problem. Because when I use different USB slot it worked fine...... FOR A WHILE. Yes it worked fine... write speed back, could detect all 3 partition, but probably it only less than 15 minutes until the problem appears again. Suddenly it ejected again.

When I post this, even I use other USB slot, it only detect 2 partition. What make it worse, the partition which had the most file wasn't detected at all. The other two only detected for less than 30 second before its ejected again. I've already doing PRAM reset and repair disk permission, still no go.

Is there any solution for this, at least for reading the data? Any other thread that had similar problem with WD MyBook? I heard they got a lot problem with this external HDD.

Hi everybody,
Maybe here is a possible solution:

I have been following this thread for a while now, waiting for a solution. My macbook has within 30 seconds or so been ejecting every external harddrive I tried to connect, for a very long time now. I was just about to reinstall Snow Leopard (10.6.0) thinking that if I don't update it, it would be as it was before...I think problems began around 10.6.5 or so.
But:
I booted from the Snow Leopard dvd and before beginning the reinstall I ran a repair disk and a repair disk permissions from the the Disk utility software. It found a bunch of errors and I thought I might as well just check and see if it made any difference and I restarted the computer. Now it actually seems that my computer doesn't self eject the disks anymore.
I have had both a small usb powered harddrive and a self powered harddrive connected for quite a long time now with no ejection.
Now I just hope this will last since it's honestly one of those things that could make want to buy a pc.

Hope this can solve it for some of you.

^After reading your post, I'm trying to do repair disk. This is my HDD status before booting into Snow Leopard DVD.
http://img824.imageshack.us/img824/2410/screenshot20110220at144.png As you can see there is 3 partition detected but one of them didn' mount. I've try to right-click and mount it.... It doesn't want.
After few second it ejected.

Then I booted using Snow Leopard DVD and using Disk Utility, now I wondering... why one of the partition still didn't mount. Is this normal?

Forgot to mention, I didn't knew if this external HDD ejected again in the middle of this process.
Because from what I recall, even when HDD didn't appear in Finder(because ejected), but if you managed to view it through Disk Utility(before ejected), It still appear in Disk Utility. Its not showed when you close the Disk Utility and opened it again. I did not close and re-open Disk Utility when booted using DVD.

Because I'm too scared with this repair disk if one of the partition didn't mount, What I just did was repair disk permission.

And still no miracle fix.

I guess I really have to try this repair disk, but is this really safe when one of my partition didn't mount?
How many minutes will it take this repair disk? Rough calculation is OK. I assume in 2 TB storage will take longer than 500 GB or 1 TB.

Is there anyone here trying to connected problematic HDD into other Mac with OS other than 10.6.5 and below?
This is just to make sure the problem is within the OS not with the HDD.
