Mac Pro :: Ejected External HD And All USB Devices Stopped Working
Mar 15, 2012
I've got a 2008 Mac Pro running Snow Leopard, and there seems to be some problems with my USB "system". When I eject an external hard drive, my usb mouse and keyboard will stop working for a short while, sometimes requiring that I unplug and plug them back in. Also, when I try to set my default audio input/output device to my USB interface, it resets every single time I turn the computer on and off. Not sure if these are related, but it seemed relevant.

I have a WD 2 TB My Book Home Edition external hard drive, I have had it for about a year... it worked fine I had a little over 1 TB of data on the hard drive and after coming home from vacation when I reconnected my hard drive it would not mount. The message was "Hard disk not recognized by this computer" so I properly disconnected the hard drive and replugged it in and reconnected to iMac and still same thing. I have tried everything in the book it feels like and nothing is working, and of course I did not have all the info backup with time machine (I REGRET and beat myself up for not) so I need to recover the data and I am not sure what to do. I did run Data Rescue 3 and it said that there was nothing on the hard drive to recover. Of course I am panicking and I have been told to send it off for Data recovery but that is going to cost up to 2,000 and I just want to make sure that this is my last resort or is it hopeless and should I just seek counseling for all the lost pictures of my kiddos...LOL I did try opening the case and inserting hard drive directly in a hard drive docking station

I installed 10.5.7 yesterday. Immediately after the installation was complete, my Apple bluetooth keyboard stopped working. Went into Bluetooth system settings, and it said that there was no bluetooth hardware found... (it's built into the machine!!)...
Also, every time I start iTunes, it gives some weird error about Adobe Flash player. I'm not at home now so I don't have the exact wording of the error with me, sorry...

Brought them out of storage on a very, very careful move and now some don't work which used to days ago.
- 320 GB lacie - works
- 1 TB elements works
- Samsung 2TB works
- 1TB firewire 400 WD was working, right up to tonight, and now it doesn't (not even on the USB connection instead of Fire Wire)
- 1TB WD (used for time machine) stopped working weeks agoGot a message about a device or such plugged into USB was drawing too much power earlier, first time ever
Turned the mac off, disconnected the power, held power button 5 secs and plugged in and restarted, no goodThe working ones seem to work on an unpowered hub but those not working of course don't Have searched the internet, nothing seems to be giving an answer of late for this.
Other issues starting to arise:
- DVD's won't eject from the iMac now
- Internet (Wireless lan connected to iinet DSL wireless router (BOB) drops out a lot and have to run network diagnostic all the time)These are less important, need to fix this HDD issue so I can back up with time machine and install snow leopard then develop my app)

I have a macbook pro from fall of 2007. So far it has worked perfectly and I've used it with an LG full hd LCD for about 1,5 years. I use a regular DVI - HDMI cable.About a month back it suddenly stopped working. The TV just tells me "No signal".I didn't change any settings or anything. The computer still recognizes when something is plugged in as the screen flicks blue and the displays icon in the menu bar lists the TV with correct model and resolution. And if I have spaces turned on it changes from 4 to 8 "screens".
I have tried everything from rebooting the computer to resetting P-RAM.
I got a new cable, no difference. However when I tried the TV with my friends MBP, it worked. So the problem is definetly in my computer, not in the TV or cable.My OS X is Version 10.5.8 Leopard.

I have a 15" unibody MBP bought in Nov '08.
Had been using the Mini Displayport > DVI adapter just fine with both HDTV and Dell monitor, BUT then all output has stopped completely!
No monitor is detected by the laptop (although the display does blink blue, as if it had detected it), tried different cables, different displays, using the Displayport firmware update, speaking to Apple, deleting the com.apple..plist files, etc
Edit: it also doesn't work in XP on Bootcamp!!!?
None have worked even a bit!.. Also read lots of forum posts of similar problems, but I can't find a solution that works!

I have a 27" iMac and I'm using Samsung SyncMaster SA850 as a second monitor (connected via a display Port cable with a mini Display Port adapter). Everything worked fine until yesterday - the Samsung screen turned black and now it only works with max resolution 1280 x 1024 (native is 2440x1440). I think I upgraded Lion 10.7.2 to 10.7.3 (I don't remember for sure though). When I connect the monitor to an iMac with 10.7.2 everything works fine. And another iMac with 10.7.3 has the same problem as me.

iMac, Mac OS X (10.7.3)

My Late 09 MacBook Air has been working a treat, not a spot of bother. All of a sudden, about 5 minutes ago, I've gone to go online to download some research papers (I'm *trying* to write an essay) and it won't load anything. Not even my Twitter app. It is connected to the right network, which is working absolutely fine on every other device in the house (windows computers, iphone etc). I've turned it off and on twice, the way that us clueless folk do.. now I don't know what to do.

I've seeing a problem with Time Machine with one of my external drives. Here's my setup:MBP 15"OSX 10.7.4Work external drive - Seagate GoFlex, via USBHome external drive - Western Digital Green, via USBÂ
I had been using both home and work drives as Time Machine backups, and things were working fine. I would have to re-designate the appropriate Time Machine backup drive when I changed locations, but everything was working.Â
The problem:When I attach the work drive and point Time Machine to the drive, it works. When I eject the work drive, the Time Machine prefs panel shows "Time Machine - work" in greyed out text as the target drive, reflecting that the drive is not available.When I attach the home drive and point Time Machine to the drive, it works. But when I eject the home drive, the Time Machine prefs panel shows "Macintosh HD" in normal text as the target drive. Worse, I think it actually attempts to back up to the internal drive, because at the next Time Machine backup interval, I get a "The identity of the backup disk has changed" error from Time Machine.Â
I've tried a full reset of Time Machine by deleting the prefs file. I've also tried verifying the home external disk.Â

My external hard drive has been repeatedly ejected improperly and now it is not displaying on my computer, not even in disk utility. How do I re-mount this external hard drive? In the past when this has happened, all I had to do was go to Disk Utility or use DiskWarrior to fix the issue but now it won't even show up in either of these apps. Â

I have been connecting wirelessly to the same router for about 4 months now, using DHCP, and having the settings on the automatic connection. I left the computer on, but closed, so sleeping, for about two days. When i opened it, the battery did not yet run out but the internet has not connected since.
I have full connection in internet connect to my network. Status says connected. If I have the IPv4 using DHCP, the status says that i am connected but my computer have a self-assigned IP adress. When I put in the IP manually, the Network setting give me a green light on airport and says that I am connected to the network thru airport. Needless to say, no browsers (Firefox, Safari, Netscape, or Internet Explorer) have been able to connect to the internet.
I have tried running Disk Utility for any errors, but there have been no changes.

Previous to 5 months ago, I had never had any problems with my iMessages working between my iPhone 5s, Macbook Pro, and iPad Mini. Now, no matter war I do I can not get my messages to work with my iPad or Macbook anymore. On the Macbook Messages app it says that my contacts are not registered with iMessage which is just not true. At one point a few months ago it randomly started working and I got all my previous messages on my Mac but after that it went back to the same problem.Â

Earlier today, this computer stopped connecting to the internet. I am still able to connect to the local wireless and check the status of my airport extreme (current model). But, all attempts to reach the internet fail. I've tested other devices (iPad, iPhone, and my mac mini) and they are all still using the wireless to reach the internet without issue. I even tried plugging the ethernet cable from the wall directly into my macbook (no modem in use, just wall to airport extreme, as we're in an apartment building), but that does not work for the macbook pro either. I reviewed the network settings for the macbook pro and the mac mini, and noticed that the DNS settings are different between the two - the macbook pro is listing an entry for Search Domains - westell.com, but my mini is not showing any search domains in that setting. Additionally, the ipv4 addresses are fairly different between the 2 computers, as well as the subnet mask (255.255.255.0 on the macbook, 255.255.252.0 on the mini) and router settings (192.168.1.1 for the macbook, 192.168.80.1 for the mini). Not sure what I can do to force/clear these settings on the macbook or anything else to check.Â

My sound has completely quit working. In the sound system prefs I get a massage saying "No output devices found". If I press the volums button keys the onscreen display comes up but has a 'no access' icon on it (a circle with a line through it). The icon in the toolbar has also vanished and there's just a blank space in its place.
Oddly whatever happened also seems to have effected my ability to view Flash movies -*the will play for a few seconds an then pause *they don't stutter they just pause. I think that whatever the issue is it was caused by a force shut down. All my applications were hanging so I had to press down the power button for a few seconds. Since then nothing!
This also effects the start-up sound which I don't get and all users of the machine are the same so it's not a case of deleting users prefs. So far I reinstalled the latest system using combo updater, run disk utility to repair disk/privileges (from start up disk) and zapped the PRAM.

I just got this new iMac that I got used and the sound on the computer does not seem to be working, I have tried doing what the computer tells me and going into System Preferences and selecting the sound option, but the sound seems to have been permanently disabled and shows that there are no output or input devices available, when clearly the monitor has speakers. whats more, is that the volume icon does not show up in the menu bar even when I select that I want it in the menu bar.

I am new to Mac and like it so far. However, I am having some difficulty in one area. Whenever I connect an external device such as a mp3 stick or my psp via usb the device will autorun like crazy either uploading or downloading something. I cannot tell. When I hook it up to my PC I will find hidden files like .fseventsd and .spotlight . And if i delete something on the device it will create a trash bin and just move it to the hidden trash bin IT WON'T DELETE IT. Is there malicious software on my OS causing this or is this a simple fix I can disable in the control panel?

I just noticed that my external drive used for Time Machine has disappeared from the Finder "Devices" section. Thankfully it continues to work fine and Time Machine can access it, but it makes me nervous!
Disk Utility sees the drive and partition just fine. I've run Disk Utility Repair disk both from the startup drive and the install DVD and there are no errors. Repair permissions is greyed out/disabled under both conditions. All the rest of my internal and external drives are visible in Devices.

I've seen 4-5 times where all bluetooth devices stop working all at once, and the Bluetooth configuration utility does not open, so the only solution is to shut down by pressing the power button. Sometimes, restarting once is enough to correct the problem. Other times, I have to do it again and hold down the shift key when I press the power button, and OS X sees the keypress and forces a safe restart.

I was installing X-Plane 9 on my fairly new Mac Pro when it stopped working. I switched disks and nothing happened, the drive just won't spin up. I have tried a number of different CDs and DVDs and none will spin up. I can verify that by looking at the position of the disk when I put it in and take it out, it never moves.I have tried the usual reboot and resetting the PRAM. (I did the command option o r and un-plugged with power button for 5 seconds)I tried calling Apple care 2 times and the message I get is, the call center is closed. That's it, they don't even tell what hours they *ARE* open.
