Repeated SD! failures
 

This has been repeatedly happening. What am I doing wrong?:

Your backup drive is in a weird state. You'll want to power off your Mac and the drive, power back up and try again.

Are you using a hub? There seem to be a lot of dries connected...at least 5, from what I can tell.

No change: I get the same exact result.

Yes, I'm using a 4-port Sabrent (model HB-MAC3). Is that a potential problem? (P.S.: The SD! failure occurs even when the backup drive is directly connected to the iMac.)

Hubs, in general, are a problem with high speed drives. Not all of them, but most. I'd avoid using them.

"Exact same problem" would be weird post-powering *everything* off. Or are you saying it didn't work "overnight"?

If you could, please send the log using the "Send to shirt pocket" Button so I can get all the details in there, and we'll continue in email.

I followed your instructions: I shut down the iMac and turned off the drive last night. This morning, I powered up the iMac, turned on the backup drive (which is connected directly to the iMac), attempted to do a backup, and received the same exact error message.

Please send the log as requested, Nick. Thanks.

Something is grossly wrong...The LaCie quadra drive is not showing up on the desktop. Disk Utility sees it as an external Uninitialized drive; and when I run Disk First Aid, Disk Utility claims "Operation successful." To make matters worse, there seems to be confusion with other hard drives.


(I'll send the log momentarily.)

I tried to send the log, but got a drop-down window indicating "Error during copy."

Yes... that window is how you send the log.

The fact that the drive isn't showing up implies that it failed (which is what we were getting too)...

So there's nothing to salvage....it's an "Uninitialized paperweight?" (I need to buy a new SD!@ drive?)

I need to see the log, Nick - without that it's very hard to comment further.

Here it is again:

Please send it with the button in the app. Thank you.

The last time I tried to do that, I was unsuccessful: I received a drop-down "Error during copy" window.

I just attempted to run another SD! backup, but since the drive doesn't show up on the desktop, I can't, and therefore can't generate a new log and "send it with the button in the app".

Yes, the "Error during copy" sheet is exactly what should happen when you send the log. You then fill out the subject, description and make sure your email is there, then send it in.

If these have been manual copies, use Window > Show Log to open the log then send it in.
