"Disk Not Ejected Properly" error after EL Capitan goes to sleep and wakes up again.

Below is my experience with Tech Support from Highpoint when I purchased the RocketU 1144D USB 3.0 PCIe Card for Mac. My computer is a MacPro 2008 v3,1 Quad-Core. 32GB Ram,

As far as I know with regards to USB 3.0 PCIe Card/controllers, they will eject when computers go to sleep using our older computer desktops, and the Problem according to HighPoint Tech, is that they have no control over Mac OS operating System.

Please read correspondence below. (starts from last msg (7) to 1st msg (1).)

1. The data is safe even when you see the message "not eject properly" during sleep.
2. If you don't have PC platform, you can skip that firmware update.
3. If there is no data activity during sleep, data should be safe without loss.

6. The firmware "FW131025.zip" is for PC system only. Unfortunately there is no package for Mac platform.

Is this package a Windows PC package? Because I'm on Mac OS 10.11.4

Is there a package for OS MAC 10.11.4?

The sleep is not controlled by us since we don't have S/W control. The driver (sleep mode) is handled by OSX native USB driver.

The package that we provided is the firmware update from USB 3.0 chip vendors. It includes the latest tune up on USB 3.0 devices. But we don't know if that helps on this case.

I've included an attachment to show how many times I get the error message when my computer wakes up. Please take a look.

a couple of more questions please...

1. What is the attachment you put in your response for?

2. I'm saddened that none of these cards will go the sleep with my operating system. Is there a potential to lose data, even though I eject the drives before the computer goes to sleep?

3. What about putting the "Computer Sleep" in system preferences Energy Saver to "Never?" Will I still get the error OR...

4. What about "Put hard disks to sleep when possible? Can this option possible work?
b. What I mean is if I put my system to never sleep, but also check "Put hard disks to sleep when possible?

Thank you!

The issue is related to OSX native xHCI driver. All products you mentioned are running the same way. We don't have control of the software package so not much we can help.

Problem Description

I Just Purchased:
- RocketRaid 644L for Mac 10.11 (No Issues)
- RocketU 1144D PCIe 5Gb/s USB 3.0 Card. (Issues - Please See Below)

My Computer is: MacPro Quad-Core Intel Xeon 2 x 2.8 GHz (Early 2008 v3,1)
My Operating System is: Mac OS X 10.11.3

Issue for RocketU 1144D:
1. I eject my USB Hard Drives, then I put my computer to sleep, or it goes to sleep on it’s own, but when the computer wakes up the get the following error messages "Disk Not Ejected Properly". Once again this happens even if I eject all my USB disks before the computer goes to sleep, as advised by your tech support.
2. Any solutions for this card?

Thank you for your time, and looking forward to hearing from you!

As I have stated before. This is not just a USB issue. I have a Newer Tech eSata PCI card for external drives. It exibits the same problem. I just set computer sleep to never and the problem goes away.

Precisely my point, however when I set sleep to never it still get the Error msg?

Anyhow that's why I put up my post, to show that these cards may not be the problem. According to my PCIe manufacturer, it's the older macs, with the newer OS X system that is the problem. Basically they are telling me Apple's fault.

I have a brand new 21" iMac running El Capitan. When the computer sleeps, my Lacie 1 TB external via USB disconnects, as well.

Trying the SMC reset and keeping the sleep going to see if it works...

This is a long-standing problem that continues for me to this day. I have tried many things.

- connect directly to usb port

- reformatted drive

- deselected Put Hard disks to sleep when possible option

- SMC reset

- installed Mountain

Nothing seems to work.

I have a solution. I recently purchased 3 WD My Passport Pro 2TB ext hard drives that are Mac certified with a Thunderbolt connection. These drives are already formatted for Mac OS's and have a built-in Thunderbolt cable, which are pretty neat. Since I started using these for all three of my brand new Mac Pro desktops with El Capitan for Time Machine back-ups, I have not been receiving this error message any longer. Yes these new ext drives are expensive, but any Mac certified Thunderbolt ext SSD's will probably fix the issue for most. Buffalo also offers Mac certified Thunderbolt ext SSD's which are a bit less in price. Hope this helps. Thanks.

You consider that a solution? So all of us who are experiencing this headache should simply go out and purchase brand new hard drives and transfer all of the data on existing drives over ALL BECAUSE Mac has a recent compatibility issue they leave unaddressed? Thanks so much for that useless suggestion.

And then do what with the incompatible hard drives?

To BKRockStar: If your think about it, it is a solution, I didn't say it was the end all. My company can provide the budget for this solution. I have tried everything in this forum and elsewhere trying to resolve this issue. This worked for me; You're Welcome!!

I understand your frustration. I am at times with Apple, however, you can never have too much storage.

Actually it isn't a solution for anyone who is having an issue with existing drives and want to keep them, which is everyone on the discussion.

You can never have too much storage? So we should keep the incompatible drives also? As I said, not really a solution whatsoever but maybe your company will pay for all of us too.

Yes it is A solution! You trust Apple will actually fix this soon? I provide a bit of feedback for a new solution and this is the thank you? You can ignore what I said and change the channel instead of arguing semantics.

I have a brand new 21" iMac running El Capitan. When the computer sleeps, my Lacie 1 TB external via USB disconnects, as well.

I tried the SMC reset also, which didn't work.

There are 14 pages of people with this problem here today. It is a real issue and needs to be addressed by Apple.

I have this problem on a "new" (late 2015) i7 27" iMac running El Cap 10.11.5

The external (backup) drive is connected via USB (USB 3 Icydock).

I also have trouble getting the iMac to recognize a new HDD (not yet formatted). It shows in terminal / "diskutil list" but not in Disk Utility, where I want to format and partition it.

I also have trouble remounting the drives after they are "improperly ejected." Requires a reboot or an unplug/replug it in maneuvre.

I've had the computer just a few days, still setting it up. The errors are unsettling in what is by far the newest machine I've had in a long, long time!

Is it time already to update to Sierra??
