By doing this and waiting a few moments the MacBook will go to sleep and unplugging the external drive will be safer (although not 100% safe). However, your next best bet is to ensure you close the lid of your MacBook prior to unplugging the laptop and taking it somewhere. In terms of how you may be able to have this drive consistently connected so that backups happen automatically without the worry of damaging your drive, there's no 100% safe way without either ejecting the drive or fully shutting down a computer first. Often they're initiated by the OS or other software, so even though you may think it's safe to remove that drive, it in fact may not be. It's important to note that not all read/write sequences are initiated by the user. The reason why this is important is that any computer (regardless of OS) can initiate a read or write sequence while it's powered up. While other operating systems may manage the ejection of external drives differently (to some degree), they still require users to eject or safely remove them prior to physically unplugging them while the computer is still powered up. Is there a way that I can have this drive consistently connected so that backups happen automatically, but that I don't have to worry about the drive being damaged?Īctually, the assumption behind your question is incorrect.

Why does OS X require users to be so careful ejecting drives? Both Windows and Ubuntu (the other two OS's I've used) seem to handle this fine. I have two other USB devices this has happened on, but they were fairly old ones I used infrequently so I assumed something else had made them fail. It's now in a state where disk utility consistently fails to reformat it and time machine can't write to it. That is, until my backup drive got corrupted. I've seen that notification countless times when pulling out thumb drives but nothing ever happened so I stopped taking it seriously. Especially when I'm in a hurry I often forget. It's a real pain trying to remember to eject the disk before I unplug the laptop to take it somewhere. I want to be able to back up my data to an external drive, so I've got a 1 TB drive connected via a USB hub alongside my mouse an keyboard. I have a laptop, which I use regularly at my desk with monitor etc, as well as on the go. Once you have every option how you want it, click “Start” to begin the formatting process.We all know that notification 'Drive X was not ejected properly'. Unchecking “Quick Format” makes Windows check the disk sector-by-sector with a low-level format that takes much longer, but it will also wipe all traces of any old data completely. The data is still on the drive but all references to it are lost, so it will be overwritten as you use the newly formatted drive. Let’s look at how you can blow the dust off those old drives and save money in the process. Don’t throw it away It takes surprisingly little effort to turn an old (or new) hard drive into an external drive perfect for stashing your extra files on.
