Click on 'Show Backup Options' to expand the drop down menu. The problem here is that most Mac disc utilities, including the built-in Disk Utility, take a Open Prosofts Data Backup. Despite these approaches, you may find a drive will continue to eject, but when the same drive is attached to another Mac or to a PC, then it will be stable and not show the same random behavior.To make life even more confusing, OS Xs Disk Utility does have a Burn command, but it becomes disabled when you click on the blank disc youd like to use for the burn. My WD Green has 41937 hours on the clock, a whooping 8979 power on count and the head has been parked / un-parked for 0000000823B2 Or for those of you who don’t want to waste time converting it from hexi, 533426 times XD Hard Disk Sentinel is telling me its death is imminent, Speed fan says it’s at 65 fitness, 85.You can also unmount it on disk utility since OS will not be present on that.boot usb1/disk1:10,tbxi (where '10' is the partition number of the usb drive, disk1 in this example). With no common hardware configuration to suggest a compatibility error, this suggests the problem is occurring from the way OS X is handling the drives.You may also learn at the same time that the power output for this bay is. In an ongoing Apple Discussion thread about this problem, numerous drives of different types, different makes, and different connections all show the same behavior. Click on the '+' symbol under 'Sources' and select your old hard drive from the 'Devices' list in the Finder window.If this is the case with your Mac, then unfortunately the problem may be in a nuance bug with OS X that has yet to be extinguished. Click the check box 'Do Complete Scan'.
![]() Power On Hours Disk Utility Drivers And ServicesOnce your password is supplied, the drive will begin the decryption process, which may take a few hours to complete, but when done, should reduce the layers of complexity through which OS X will access your data.Uninstall drive management tools and driversOS X contains all of the drivers and services needed for accessing and mounting a locally-attached hard drive, so for the most part, hard drives you use with your Mac should not require any third-party drivers. To do this, right-click the drive and choose the option to decrypt from the contextual menu. If any errors are found, attempt to repair them.If you have encrypted your external drive, then try decrypting it to see if the problem will go away. Then use the Verify Disk option in the First Aid tab to check the drive for errors. To check these, open the Disk Utility program and then hold the Command key and click the device name as well as any indented volume names listed under it to select them all at once. When you purchase a drive for your system, it will likely be formatted to FAT32 and perhaps have a custom partitioning scheme to work with different operating systems and provide you with backup software, drivers, and other offerings. If your drive is a special RAID array or other setup that requires custom driver software, then be sure you have both it and your drive’s firmware updated to the latest versions.Granted this last approach is the last resort option, but is an often-overlooked detail. These are developed separately from OS X, and it is possible any small update to OS X could cause compatibility issues with these tools and drivers. If these are a requirement, then consider switching to a different device, but if not then consider uninstalling any drive management tools you are using. I’ve read complaints about nearly every drive manufacturer. Post navigation ← Three ways to open the current Finder window in the OS X Terminal How to protect your Mac from the ‘Dark Jedi’ firmware hack →Does the problem happen with “several” Seagate models on your Mac, and other Macs you’ve tried them on? Have you read reports of the problem with these particular drives from other users? If not, then the trouble may be with your Mac, not with the drives. When done, copy your data back to the drive and see if regular use of it is more stable.This entry was posted in Troubleshooting and tagged external drive, Hard Drive, USB drive on Jby Topher Kessler. Therefore, do what you can to back up all contents of the drive, and then use Disk Utility to fully partition and format the drive. These can be with the formatting, but also with some nuance configuration file or two that OS X stores on the drive, which may be the root of the error. The drive case, which includes the bridge, is often made by someone other than the drive manufacturer. As well, most manufacturers offer a range of quality in their drives, which may be a factor in failure rates.All that being said, I’ve had more problems with bridge failure in external drives than with the drives themselves. Which suggests to me that there is, in fact, little difference between them. What is the best ftp client for macIf the drive works with one of these devices, then I know it’s the connection bridge in the drive enclosure that died. I also have a NewerTech USB 3 Universal Drive Adaptor that can handle ATA/IDE/ATAPI drives in addition to SATA drives. Western Digital does not offer replacement cases so I got one from OtherWorld – and the drive lives on.When an external drive fails I remove it from the case and test it with a NewerTech Voyager Q for 2.5″ and 3.5″ SATA drives. This happened to me recently when a Western Digital My Passport Studio drive failed. Even when the case is made by, or provided by, a particular drive maker, if the drive can be removed it can be installed in another enclosure. Generic cases are also available and are usually less expensive than brand-name enclosures, though they provide fewer connectivity options. So, I thought, what might be different today, causing this problem to come to the surface?For context, I’m running a late 2013 Mac Pro (the cylindrical one) under OS X Yosemite 10.10.5. However, if you have important data on a drive that will no longer mount reliably on the Desktop, using a device like the Voyager Q or a drive adaptor is easily the least expensive and most effective way to recover your data.All this may seem to be only tangentially related to the issue Topher covers in his article, but since the real cause of the problem is so difficult to track down and may end up being impossible to solve with the procedures he recommends, ignoring the electronics in the drive bridge seems to me to be going only half-way to a solution.Wow — I had the “spontaneous disk ejection” problem several times yesterday, after never having had it before. Usually, but not always, these are the cheap ones, where there is no way to open the case without breaking it.Undoubtedly people find it easier to just replace the entire external drive unit rather than going to the trouble of removing the drive from its case to test it. I avoid, when I can, buying a drive that is completely integrated and cannot be functionally separated from the case. That translates to about 35 to 40 minutes to transfer one huge 700-GB chunk of data.So, back to what was different when I experienced the spontaneous ejections, compared to my more routine usage:(1) It was quite hot that day, and the room where my Mac Pro and drive enclosures live doesn’t have any air conditioning. These copy operations are relatively speedy — somewhere around 300 Mbytes/sec. I was in the process of copying very large chunks of data (200-700 GB) from a 2-drive RAID-0 array in one RS-M4T to a similar 2-drive RAID-0 array in the other RS-M4T. Actually, when I encountered the spontaneous ejection problem, I had TWO RS-M4T enclosures connected (via two separate Thunderbolt ports on the Mac Pro) — i.e., not daisy-chained. As dust accumulates inside a machine, its cooling performance will likely deteriorate (impeded air flow).(4) I was using 3 Thunderbolt ports simultaneously (2 for the two RS-M4T’s and 1 for my Thunderbolt video display).(5) The speed of the transfers was boosted by the fact that I was reading from one RAID arrray and writing to a different RAID array in a different RS-M4T enclosure. I use it every day and it’s probably had time to accumulate a significant amount of dust inside.
