If you use an optical drive, you may as well get the best.
When the drive is flashing, it usually means your Mac is running through a series of check to mount the drive. Try using Terminal to eject the disk, then shut down your Mac, wait seconds and unplug the external drive from the Mac, and power your Mac back on. Wait for your Mac to fully boot, then reconnect the drive to your Mac and see if it now recognizes it.
I have an external lexar ssd mb that I usually use on my MacBook Pro. Suddenly yesterday when I restarted my laptop the disk stop showing up. I tried disk utility but the lexar is not showing up too. I tried the console and not showing up. Then I connect the drive to my old iMac with Sierra, and the disk mounts and shows up. Tried to format again, only appears on Sierra and not mojave. Also appears in windows but not mojave. Does anyone has a solution?
Also, what format are you choosing to initialize the drive with? That drive for Mac should work out of the box with no formatting required. It might work. Hi, many thanks for all this great info. The hard drive powers up normally with no weird noises and has a continue white light no flashing and as far as I can see all is normal. But for some reason, it is not showing up in Disk Utility, Terminal or Console. Thanks for getting back to me.
If you have quick access to another Mac, I would try connecting the drive and see if another Mac picks up the drive using System Report or elsewhere. Close all apps 2. Shut down the Mac 3. Once powered off, connect the drive and if available, connect the drive to its own power source 4. Power up the Mac 5. Remember to try multiple ports on the Mac—just in case there is a problem with a port.
If the problem replicates on another Mac, then the problem is likely some hardware issue in the drive itself—perhaps a loose cable or some other issue. Hello, I read this article, you described so deeply. If disk already mounted and system goes to sleep, it also powers down ports, including USB ports. It is very bad when you need to transfer something right then. It can be risk that on the external drives which means you cannot transfer what you need between devices at all.
I did not know why this happen then I searched and found that it happens because multiple reasons like faulty cable, damage USB port, file system corruption, and so on. One more point, I would like to share about data recovery software. During research I found that there are software available online that are very helpful if some lost data during this update, they can recover easily. I read reviews and most of them suggested Stellar Data Recovery.
I used free demo to check and found better result.
But, I am wonder to read this blog because of you described a so many tips or solutions to fix it which I did not know. Very useful article for me I personally believe. Thank you so much. I knew the drive and cable were okay. A reboot would always fix, but who wants to do that every few days?!
It is the first one which talked about what I am sure is my issue, namely power and recognizing external disks with a port expander. But now with my new Mac Pro connected through the new Thunderbolt connector, not all of the disks mount when I turn the computer on. Unplugging the various disks and reconnecting them eventually gets them all to work, but there is no procedure I have worked out that reliably gets them all to mount. If anyone who has experienced this problem has found a permanent solution I would be interested, even if I need to buy a different port expander.
We suggest you check out this Apple Shop page where they list the hubs they sell and recommend for Macs. I see it grayed out in Utilities and I just need to know if I try to mount it there will I lose my files? What we do suggest is purchasing or borrowing an external drive that does work with your new MacBook Pro and then duplicating those important files onto that drive using your older MacBook.
Since Yosemite includes AirDrop, you could also try airdropping those files to your newer MacBook—this should work. All went well. Even after trying all your steps. Strange thing is when it does show under USB3. When I first moved my photo library, all was well and it did open from the external LaCie, right after moving it. I purchased an adapter so that I could plug in my external hard drive.
The drive lights up but is never recognized on the new mac. My last MacBook with relevant ports had no issues recognizing this hard drive last week. When you plug in the adapter, it should click in—not be loose. You can even go to an Apple Store and ask them to connect your drive to a Mac to test its functioning. Inserting the external hard drive cable slowly into the macbook worked for me too. Quite Strange…. However, if Mac has been only logged out rather than shut down, then at Login the drive is detected but not mounted you can see it listed in Disk Utility but greyed out.
At this point it responds to a manual re-mount and then functions as expected; but it used to work properly. It seems that something has inadvertently happened while browsing or I have accidentally clicked on something affecting system setup. In trying to solve this problem I resorted to resetting the hard drive, doing a full-Time Machine backup from scratch and then full encryption. I suspect a corrupted keychain access or a background app Malwarebytes? There was a big in High Sierra back in that impacted mounting some external drives.
Some readers found that updating to macOS Mojave solved any problems with mounting external drives. You should also run Apple Diagnostics to see if there is any hardware issue at play. Restart your Mac and press and hold the D key on your keyboard. Keep holding that D key until you see a screen asking you to choose your language, the release.
One of my external drives decided was not going to show up on my Mac. It would not mount. I tried every thing in this article spending hours trying to get it to mount. It just could not be found by disk utility or or the terminal. You could see it but it just would not respond. Till I got to the bottom of the article it was suggesting I recover the info on the drive using a software called Stellar Data Recovery.
Once I downloaded this free version and started to run it low and behold I noticed that my drive showed up on the desktop. I could even open it up the and see all my files. I had about 6 Photo libraries some from iPhoto years ago. And I had folders with s of photos I did not want to loose.

This was the only thing that worked to get my drive back. My mistake was disconnecting usb cables to move some things around without first ejecting the drive. This did not effect my other drives but just this certain one. My suggestion to everyone is to remember to eject before pulling the usb connectors off the computer. Thanks in advance. Have you tried Disk Utility?

Does it see your drive and the info on it? In that case, remove the hard drive from its current enclosure and place it in another enclosure—then see if your Mac recognizes it. Thank you, thank you. Your tip solved it for me. The only thing I would add is the necessity to turn off SIP system integrity protection , otherwise one cannot modify the system file. However, I do wonder how people less technically inclined would manage.

Thanks to the Luz from the blog you can once again be illuminated… Apparently, Apple engineers had the need to test the Superdrive with non-MacBook Air computers themselves, so the driver already has an option built-in to work on officially unsupported machines!

Thanks to the Luz from the blog you can once again be illuminated…. Apparently, Apple engineers had the need to test the Superdrive with non-MacBook Air computers themselves, so the driver already has an option built-in to work on officially unsupported machines! All you need to do is enable that option, as follows:.
In fact Luz provides two options, one it seems is more reliable than the other. While it seems to work fine in many cases, some users ended up with their Mac not booting any more afterwards. Is that possible?
I do not want to disable my internal DVD drive. Thank you. The region encoding is set at a firmware level on the physical dvd device. This link seems to suggest is should work, and even a way to work around it with VLC before you buy a second DVD drive. I will try VLC, thanks so much. The point of using the FireWire enclosure is to connect it to a FireWire port for a faster connection.
Maybe try copying the file to your desktop, editing that version and copying it back into the correct folder. This finally worked!
