MacBook Pro :: OS X Mavericks (10.9.4) External Drive Randomly Disconnects
Aug 24, 2014
I have a external SATA drive that was used on my old Windows laptop. The interface for the drive is USB 3.0. Whenever i try to view my files on the drive, the drive randomly disconnects, and notifications pop up saying that the drive was not ejected properly.
Also the drive has been reformatted to a Mac format, but it still continues to do this.

I have had my new iMac 21.5" for about 2 weeks now. Yesterday I picked up a 500 GB LaCie USB Drive to be used for my Time Machine drive. I have the drive connected directly to a usb port on the iMac. Sometimes when the iMac goes to sleep, when I wake up the iMac I get the dreaded "This Drive Has Not Been Disconnected Properly" warning.
I have made sure that the "Put Hard Disk(s) to Sleep Whenever Possible" option is not selected under the Energy Preferences. I have tried multiple usb ports, same issue. This isn't a constant issue, it just happens sometimes. Is there anyway to tell Time Machine to mount and unmount my drive when needed?

I own a few external harddrives, however one in particular (western digital 2tb) will randomly disconnect and a window will show about "device removal with the red little stop sign shape" then it will randomly connect again (and sometimes i have to physically unplug it and plug it back in), does anyone know what is going on here? None of the cables are being touched, it's really strange, the only thing i can think of, is maybe i have a loose usb cable and need to replace it? or maybe a faulty usb port?

Machine is an early 2008 Mac Pro. I'm connecting two external SATA desktop hard drives via eSATA (NewerTech Voyager S2 enclosures) and a Newer Technology eSATA Extender Cable (connected to the 5th and 6th internal SATA headers). One of the drives is used as a Time Machine backup disk. This TM disk has been periodically disconnecting and generating warning messages about improper ejection. It reconnects with a restart, but usually will disconnect again within a day. I swapped the drives in the docks, so each was connected via the other dock, cable, and internal header. The same problem persists - the TM disk disconnects periodically despite having switched docks.

I have had several issues with the USB on my brand-new Core i5 macbook pro. It randomly disconnects USB devices. I've had the issue with multiple USB devices - same story with each one. Further, iTunes will only recognize my iPhone if it is in the port nearest the magsafe connector. The other port fails to recognize my iPhone entirely. Anyone else having a USB issue on their base 15" that was released today?
Furthermore, any suggestions of what to do about it? I'm having a hell of a time restoring my iPhone with this issue... And the Apple Store is over an hour away-I planned a special trip to buy this laptop.

I have a Western Digital 2TB USB Hard Drive that Ive been using perfectly for a couple of years on my MacBook Pro. A couple of months ago I bought a 27inch iMac and started using it as my main computer. So I had that hard drive connected to my iMac.
I started to notice that during large transfers (be it many files or 1 big one), usually into the Gigs, I suddenly got a warning message saying that the Hard Drive was inappropriately disconnected. It doesnt appear in Disk Utility so I have to manually connect and disconnect the drive in order for it to show up again on the iMac. I tested it again on my MacBook and the same thing happened.
Another problem:
Sometimes it will dissappear from the iMac without a warning message, it just doesnt show up. (Usually after long periods of inactivity). I then have to manually disconnect and connect for it to show up.

I recently purchased the $1699 Macbook Pro a couple of weeks back and now it seems that my airport randomly turns off. I can't even get it to turn back on; I have to restart my macbook to get it working again.

My brand new imac randomly disconnects from the internet. We have a BT hub - wifi. I have googled this issue and see that it is relatively common and it is incredibly frustrating. It is fairly simple to reconnect each time but it is driving me mad having to. It generally happens when the computer is asleep but sometimes in the middle of doing something.

So, after getting it hooked up and connected to my router, which is set to only allow only 4 devices to have access to it (my comp, iphone, wii, and gf's laptop), i find that my gf's laptop (which is the only device using a corded connection) is the only machine able to get online without problems now.
I can pick up my WiFi network occasionally after a restart, but then it usually goes out after a random amount of time... anywhere between 10 minutes to an hour or 2.

I've been having problems staying connected on my Powerbook G4. The wireless works perfectly but the ethernet does not. I've been using the dorm ethernet jack to connect. The problem is that my computer can't maintain a consistent connection through ethernet so it randomly connects and disconnects. I called my campus' IT department and they told me that it must be my computer because they're system said that it didn't detect my computers IP address. I called Applecare and the person told me that it must be something wrong with either the network card or the ethernet port. Anyway, he gives me a case number so I can go get a repair. Unfortunately an Apple Store is far away from where my school is so I went to my school's bookstore instead.
The bookstore is an authorized service place. I drop the computer off to them and they sent it to Apple. I got a call today from the bookstore guy saying that the Apple technicians discovered that "liquid" had gotten into the motherboard and refused to service my computer. I was really angry when I heard this because I keep absolute care of my laptop. I know for a fact that no water has ever been around my laptop. I'm guessing it must have been negligence on the bookstore's part. I declined the $1300+ repair estimate so now its on its way back to me. I have a brother that works at the Apple Store and he just suggested going directly to an Apple Store this time. Will they just refuse warranty repair again?

I've seen several discussions on external drives randomly ejecting, but didn't see any concise resolution. I have a Western Digital Passport, P/N WD320ME-01 2209A, using the OEM USB (2.0 I think) cable (~12 inches long). My ~4 year old mac book is running OSX 10.7.3. I use this drive for Time Machine B/U. Seemed to work ok (no ejects) when Leopard was the OS, but, after going to Snow Leopard, and now Lion, I get 'disk improperly ejected' errors when trying to run TM, or ever Repair under Disk Utilities. I did get one good TM back up, under Lion, after reformating the drive [extended (journaled)], but the next time I tried to run TM I started getting the 'improperly ejected' errors. Don't know if there is an issue with Lion (and earlier SL), or with WD drives. The fact that it originally worked leads

So I have an external hard drive hooked up to my MBP via USB. I've noticed that every now and then (maybe every half hour or hour?) the drive spins up. It's actually really annoying, as the drive makes a loud sound as it spins up.
I can't figure out why it does this; the drive spins up and then goes back idle. Time machine is DISABLED, spotlight index on the drive is DISABLED as well. I use the drive solely for storing movies/music. There are NO applications installed on it. The only apps I have open are finder/preview/safari/firefox/adium/itunes. My guess is that some process is trying to access the drive for whatever reason now and then.

I cannot be 100% sure but it seems like my problem started when I installed Apple TV and started home sharing. When my Mac goes to sleep and I start it up the internet is disconnected. I check in the settings and the network shows a signal and connected. I do not get emails and I cannot connect to the internet though. I have to restart my computer then everything is back on. I cannot stand quitting all my work to restart my computer so many times a day.

How to back up MacBook Pro mavericks..without a separate external drive

I have a western digital hard drive that had previously been working flawlessly on Lion, however when using it with Mavericks it had suddenly stopped working meaning it would no longer be found on the desktop or in finder. I have been using the hard drive as a time machine backup. the obvious next step was to launch disk utility and look for a solution. I have found there two hard drive names in disk utility, the first is the HDD name of Western Digital and the second is the "Time Machine" partition. Running first aid on the partition resulted in an error and that the disk could not be repaired. This HDD is important and the data cannot be lost.

My HD on my macbook pro crashed and I did not have it backed up. I have the crashed drive connected to my other mac as an external drive and I am trying to get my mail files. I was using Mavericks on the crashed drive and I am trying to get them off onto a mac that has Mavericks too. How can I find my mail files on an external drive? If I install it as an external drive it will not boot up.

I have recently bought a MacBook Pro (10.9.4) with a 128 Gb solid state drive. My intended backup strategy is to have all my documents on an external 1 Tb USB3 drive (i.e, not in the MacBook Pro) and to back up that drive AND my Macbook (system, applications, mail etc) to another, powered 2Tb drive. I’m assuming I’ll have to partition the 2Tb drive first, by the way.

I have a MacBook Pro running OSx 10.9.4 and have been successfully using Time Machine with a WD My Passport External Hard Drive for a while. Now (after 10 days with a successful back-up), the computer will not back-up. I have gone into disk utility and tried to erase, partition, and/or repair the disk, but repeatedly get error messages - it can't erase the disk, re-partition the disk or unmount the disk.

I recently purchased a Macbook Pro 15" for college. I set everything up and it was working perfect until a few days ago. When I try to send a message on my macbook the person's name I am sending it to is blue for a second but quickly changes to red but I know they are using iMessage because I am iMessaging them off of my iPhone. Also, when I try to facetime someone from my macbook it works perfectly and I can receive facetimes too.
Some of the fixes I tried:
Logging out of iMessage on iPhone and then logging back in
Deleting preference files (This is a huge confusion for me, I simply don't have the files. Ex: com.apple.imservice.iMessage
I've tried editing the preferences on my macbook and iphone . I recently switched from my 5c to a 4s because water damage completely ruined my 5c.

I got a new Macbook Pro Retina (mid-2014) a few weeks ago and the trackpad and screen randomly freeze even when the only thing I have open is Safari. In other words, it doesn't feel like my computer has a 2.6 GHz Processor and 8 GB 1600 Mhz Memory. My downloads folder also constantly has the loading bar under it; it goes away when I remove it from the dock and replace it, but appears again after downloading one thing.
This is really frustrating when I got a new Macbook so that I wouldn't have to deal with these types of problems. They're all issues that I never encountered with my Macbook Air (mid-2011).

I have 3 macs, Macbook Pro, iMac 27" and iMac 20". The drive shows up on the Macbook Pro and the 27" but when I plug it into any of the USB ports on the 20" I get nothing. Nothing in the disk utility, nothing on the desktop and nothing in finder. I have already tried PRAM and SMC resets with no change in status.

I have a 1 TB Lacie external drive. it was originally formatted as Mac OS Extended (Journaled, Encrypted). It also might have been formatted as a bootable drive, but I am not certain. Today I mounted the drive, entered the decrypt key and want to re-format the drive as Mac OS Extended (Journaled). I am using Disk Utility to do this. When I click on Erase within Disk Utility, I get this error: I am using Mac OS X Mavericks. how to fix this so that I can re-format the drive?

I have used a Samsung HX 1Tb external hard drive under OSX Snow Leopard with absolutely no problem. Since I upgraded to the free (improved?!?) OSX Mavericks my Macbook Pro cannot "see" my hard drive. All I get when I plug it in is the following message -
my MacBook thinks that the hard drive is formatted for windows - but why should it work OK under Snow Leopard but not with Mavericks? I don't want to simply reformat the external drive because I'll lose all the files stored on it.Is there suitable software/Apps that I can use to let my Mac access this external hard drive.Incidentally my partners new Macbook Air can still read this hard drive.

I use a 250GB external HD for most of my working files. It has five equal partitions. In one of the partitions--Cedar Mill (see attached images) --another partition (CM News) shows up in Finder. Inside CM News is another copy of itself ad infinitum...
I am reluctant to delete them without knowing what I'm doing. How they got this way.
I haven't noticed any particular problems, except possibly slow search times for opening/finding files...
