Is anyone else getting the error message you get when unplugging a disk such as an external HDD without ejecting it first? Lately, I've been noticing it and I haven't done anything. I do have one external HDD for time machine and its still plugged in. This message has popped up about 3 times now for no reason.

Maybe it's to do with a power saving setting? The drive goes to sleep but the computer thinks that it disconnected without properly ejecting?

That's a total stab in the dark, I don't believe it's the cause myself. But it's the only thing I can think of right now.

Well twice now, it was one my screen (login screen) when coming to my computer after not being used for a few hours. I would use my computer, click on "login window" and my computer's screen would go off after a while and I would come back, click on the track pad and the screen would come on and I would see the login window but I would also see the message about the disk not being ejected properly.

Apparently, this is a more wide-spread issue then I thought. i did some searching and people with various brands of external HDDs are reporting this problem. Some have resolved it by turning off the built-in sleep timer and it looks like some others are still having the problem such as myself. I've tried possible solutions such as shutting off the built-in sleep timer but to no avail.

Can't edit my post anymore, but I wanted to add: Not all external drives respect the operating system's preferences. So even though you told OS X (or Windows for that matter) to not put your hard disks to sleep, the drive's firmware could overwrite that and go idle regardless. This explains why unchecking "Put the hard disk(s) to sleep when possible" doesn't solve the problem for everyone.

I actually went into the external drive's settings via WD software and told it to disable to the sleep timer along with going into the OSX energy saver preferences and unchecking that box. You did have a good point which is true about it not solving the problem for everyone. From what I've found in internet and other forum searches is that certain things have resolved it for some while other things have solved it for other people.

Have you tried researching this in their own support forums? You're probably not the only person having this issue and they may have offered a solution. If you do find one, come and share it here!

That actually was going to be my next shot. I actually hadn't gone there yet only because I thought maybe OSX was at fault (I was only guessing) but, I will be going to WD support forums and seeing what I can find out.

In that case I'd contact WesternDigital. I did so in the past and they were fairly (strong emphasis on fairly :p ) fast in getting back to me. It doesn't seem like this issue lies with OS X.

I completely agree with you. I think this drive or current firmware (yes, FW is up to date) is crap. Its being random now whether I can get it to mount at all. I sent in for a RMA replacement as its still under warranty. Its replacement should be here soon and the current one will be going back. That's going to be my next step. We'll see how it goes from that point on.

Keep us posted! Interested to learn how this thing plays out. :)

If I had to take a stab at this and guess. My best guess would be that its bad firmware. Even though I told the drive's own sleep timer to never sleep, it still does it. The System Preferences regarding HDD sleep is also unchecked.

I had the same problem with my mouse and keyboard on an iMac as well Circa 2009ish model. Would randomly make the disconnect and connect noise. No functionality loss just would happen at times. I disabled my Bluetooth at one point and all of that stopped. I have no idea if that was what caused all of that to stop. I would say firmware or driver problem. Check for updates.

    • Dragon's Dogma 2: Dark Arisen expansion to bring snowy region, new updates also coming

      By LoneWolfSL · Posted

      Dragon's Dogma 2: Dark Arisen expansion to bring snowy region, new updates also coming by Pulasthi Ariyasinghe Capcom had a surprise waiting for Dragon's Dogma fans today in the Nintendo Direct presentation. The company revealed an expansion for the second installment with a name that should be familiar to series veterans. Coming later this year, Dragon's Dogma 2: Dark Arisen is promising a massive new region to explore, new monsters, fresh skills to learn, and more. The studio says players will be heading to the Northern region of the world, named Norgan, to find new secrets about an undying "Fallen Dragon." There will be forgotten relics that the protagonist can find to unlock fresh weapons and skills the expansion is introducing. Players will also be able to find mysterious equipment from a previous Arisen as a part of the expansion, all part of 12 Lost Rites Dungeon Challenges they must complete to gain access. In Neowin's own review, I found Dragon's Dogma 2 to be an impressive RPG when it launched back in 2024, giving the title an 8.5/10 for its class variants, companion system, and immersive exploration. "Once a prosperous region of the kingdom of Vermund, it was abandoned many years ago for reasons unknown," says Capcom about the new region. "Long has it been since any soul traveled its paths. Blanketed in heavy snow, these frigid lands are home to savage hordes and creatures of unbelievable power. Those who are capable of vanquishing such fearsome foes, or those who possess a keen eye for exploration, will find themselves rewarded with powerful relics." Dragon’s Dogma 2: Dark Arisen expansion launches on October 9, 2026, with a $29.99 price tag. Ahead of the expansion release, Capcom is also planning to release two free updates to the base game. The first will land tomorrow, June 10, bringing more accessible fast travel with an Eternal Ferrystone and other quality-of-life adjustments. The second update will land sometime in August, aiming to improve frame rates, add more save slots, and bring even more community-requested adjustments. This expanded Dark Arisen edition is also launching on the Nintendo Switch 2 on the same day the content comes to PC, Xbox Series X|S, and PlayStation 5.

      Classic themes are just the colors on the bar like the olden days, if you use the image themes, it does fancy transparent backgrounds and it makes the elements of the app look like they are transparent bubbles. This sample image shows what it looks like.

      Good point, unfortunately. NextDNS has far more filters and workarounds than uBlock, and it's easy to implement.
    • Windows 10 KB5094127 Patch Tuesday improves File Explorer search and more

      By TarasBuria · Posted

      Windows 10 KB5094127 Patch Tuesday improves File Explorer search and more by Taras Buria The June 2026 Patch Tuesday updates are here, bringing mandatory patches to users with PCs enrolled in the Extended Security Update program for Windows 10. Microsoft is rolling out KB5094127, with build numbers 19045.7417 and 19044.7417. Changelog includes the following: [File Explorer] This update improves File Explorer search, including support for Chinese text, and UTF 8–encoded files without a byte order mark (BOM). Text now displays more clearly and consistently across search results, Content view, and tooltips. [Secure Boot] This update enables dynamic status reporting for Secure Boot states in Windows Security App. This update adds a new policy setting, LimitSecureBootRequiredServiceData, under Computer Configuration > Administrative Templates > Windows Components > Secure Boot. When this setting is enabled, Windows limits the Secure Boot service data it sends by suppressing the event normally sent to Microsoft. This policy is also included in the Windows Restricted Traffic Limited Functionality Baseline package. For information about the policy, see Manage connections from Windows 10 and Windows 11 operating system components to Microsoft services. With this update, Windows quality updates include additional high confidence device targeting data, increasing coverage of devices eligible to automatically receive new Secure Boot certificates. Devices receive the new certificates only after demonstrating sufficient successful update signals, maintaining a controlled and phased rollout. As for known bugs, Microsoft has the following to say: A workaround is available in the official documentation. Today's updates are available for PCs enrolled in the Extended Security Updates program only. If your PC is eligible, you can download the update from Settings > Windows Update or from the Microsoft Update Catalog here.
    • Signal accuses UK government of using child safety as cover for mass surveillance

      Then the solution is to not let children have easy access to smart phones or internet until they are older, not mass surveillance. Only this would require parents to do actual parenting, most likely, as with any good solution to the problem.
