Mac Pro :: Random Disconnection Of Internal HDD
Mar 19, 2008
I've got a strange problem with one of two internal HDD on my PowerMac G5. All of a sudden, it disappears from the desktop with an error message about improper devise removal. I've checked the cables: everything is like it should be. After restart all drives are back at the desktop. But it keeps happening fsck didn't help. I'm running DiskWarrior right now. What could it be? Both drives are quite new Seagate 7200.10, I think... Not older than 1 year.

When using PC, WINDOWS warned about not to disconnect USB/FW connected hardware until you ask the system to do so and the system confirmed it was safe to do so. However, I've been told that with Mac you can directly connect/disconnect the cables without any previous confirmation from the system. I'm confused, since I can not find how to get confirmation form the MAc that it is safe to disconnect the USB/FW.

Every 5 to 10 minutes, my MBA "seems" to disconnect from the internet, although according to my Mac, it's still connected and shows my current IP address. I know it's not my router (Dlink DIR-624) because everything else stays connected. I don't have a problem with my Dell laptop, AirPort Express (used only to stream iTunes to my home theater), iPod Touch or either of my iPhones. The problem only occurs with the MBA.
Renewing my DHCP Lease fixes the problem for a couple minutes, but then I lose connection again.

I accidentally unplugged the surge protector 2 days ago. When I replugged it in, the computer was not turning on. The green light on the tower was on, but with absolutely no signs of life.

The Wi-Fi keeps disconnecting (all networks), although they continue to be available on my iPhone, Mac Book Air (OS X Lion 10.7.3) and another PC. I have to reselect the network manually in the shortcut (top right of the screen), a few seconds later I am connected again. The problems seems to be related to inactivety on the iMac. For example if you are reading some pages, without any key strokes or mouse activity, but there does not seem to be any specific time for repeatability of the problem. It is just anoying.

I recently bought a late 08 aluminum macbook and have been quite happy with it but from quite some time I've noticed that while I'm on internet and on adium (where I noticed the most) the signal goes off for a couple of seconds and then it comes back. First i thought it was ok but it's been happening really often and is quite annoying since it happens several times a day and only happens to me and not anyone on my network (everyone else has pc`s and are also on wifi). So I wanted to ask.. is it possible my Airport card is failing? or is my router the one failing.

I have four external drives connected to my MBP: One USB 2.0 drive, and three that are connected via FireWire 800 (they are connected "in line", i.e. one is connected to the MBP, the second one is connected to the first one, and the third one is connected to the second one).For several months already, I experience the following anomaly:When an external drive hasn't been used for a while it normally goes into sleep mode and the otherwise turning disks come to a standstill. The problem, however, starts when I want to use the data of one of the "sleeping" drives (e.g. by opening the Finder): Then one or more other drives, that are also in sleep mode, but used to come back into "active" mode in the past, are suddenly disconnected. MAC OS X then displays the message that a disk has been disconnected without being formally ejected (via the dustbin). This is not normal, of course, and I am afraid that this behaviour could harm the disks health and live time.I have tried the Disk Utility Tool of OS X for all the drives mentioned, but they seem to be ok.

I've been having this problem for awhile- maybe some of your intelligent people can help me.
I have an airport extreme and two 1TB hard drives connect to it through a USB hub.
Every night, I have a program that copies one of the hard drives on to the other. This has worked for the first year that I had the setup.
Recently, when copying, the mounted hard drives will disconnect and I will loose my internet connection. When this happens, the green light on my airport extreme turns to yellow and starts flashing- is it is restarting.
This also occurs if I manually try to copy a large batch of files.
I'm usually decent at debugging computer issues, but this one has me stumped.

I've had an WD My book 500 GB external for about as long as I've had my macbook about 1 1/2 years. No trouble with it at all, until yesterday. At some point either the power got cut or the cable was pulled out incorrectly it got disconnected from the mac. Thus resulting in it not mounting now. I've tried disk repair and shutting down the macbook and restarting...plugging in after everything is started. but to no avail. I am a photographer and about 25% of my photographs I don't have backed up anywhere else. So if I can't get it to work. I need some way to get the information off and reformat. or get it working correctly.

Putting her MacBook Pro/Maverick to sleep works fine, but when she raises the lid the Wifi connection is broken, and cannot be acquired unless she reboots. Does a switch exist for this anywhere?

I want to keep my applications etc on one internal HD and use my second internal HD as a back up.I am a graphic designer, and i have been backing up to an external LACIE Porche 160 Gig firewire HD. This has worked fine, but...My second internal HD (112 gig?) is still loaded with 10.3 and has adobe CS2 on it along with some other crap that I no longer need.I have loaded Adobe CS3 on my primary drive and have all the files I need on that one...What is the best way to set up my second HD as a "slave" drive to improve the performance of my G5 dual 2 Ghz??Will there be any issues now that I loaded Leopard on the primary HD?

How do I transfer all data from my old internal hard drive to a new internal hard drive? I have an iMac with a 320gb internal HD that is full and I am replacing it with a 2tb internal drive. I have several external drives; 1 tb, 2tb and 3 tb. The 2 tb is being used for Time Machine. Do I have to buy an enclosure? If so, where would I get an inexpensive one? I also want to partition the new internal drive for Windows, and I'm not sure how much space to use for that. I plan to use Windows to check my work in PowerPoint created on my Mac for clients on PCs.

I keep hearing this random sound while using my new MBP. Sounds like a guitar chord being strummed but it's very, very brief. It's happened while in Firefox, iMovie, Findit, etc. What is it?

What would cause random restart? Maybe one in 15 times, when I lock my display, I will find that in the morning, my computer had restarted without my doing. Irritating as I rely on it for an alarm clock and as I have to log in, the alarm doesn't restart in the event this happens (almost overslept an exam today because of this). I am on a late 09 mb with 10.6.5 running.

I have a 2008 iMac running OSX 10.6.5, 2.66Ghz Intel, 2 gig ram. I'm getting random blue screen crashes at least weekly. I don't have any hardware connected except an iomega external hd for Time Machine (and of course a keyboard and mouse). I'm never doing anything exceptional when it crashes. Usually just internet browsing (Chrome) or word processing (NeoOffice). The screen just suddenly goes gray/blue and I have to force it to shut down with the power switch.
I upgraded to Snow Leopard at the same time I installed Windows 7 (Boot Camp) and purchased the external hd. The problems started around that time. I have since wiped the disk and reinstalled both OSs, but am still facing the same problem.

I have had my first Mac for about a month now (iMac 24" 2.8, 4GB). I have started noticing in the last few days, a somewhat frequently appearing "spinning disk" (don't know what it is called, but in Windows-land they call it "clocking"). In any case, I never saw this when I only had 2GB of RAM. Nor after I upgraded to 4GB which was a couple weeks ago. But lately this is occuring enough to be a bit annoying.

I realize that I'm opening the door here, but here goes. After my SL install, I'm getting a strange, seemingly random, "ding dong" doorbell noise. Not related to time of day that I can tell. Maybe a coupe of times per hour, maybe less...very strange. The only other thing I did that I'm aware of is installing iStat pro. I have mail running in the background, but it's not any mail noise that I've heard. Any ideas? (I know, I know..."Someone at the door, "My wife calling me, yada yada...).

I recently was given a G3 iMac (Slot Loading), and was wondering what I could do with it. So far, I'm using it as an MP3 player, and I put some random videos on it, but not much else. I'm planning on doing a youtube series about ways to use an old Mac, but theres one problem: The iMacs screen is difficult to record with a camera, (scan lines) and there are not video-screen-capture programs available for OS 9. I know this post seems confusing, but basically I'm wondering if anyone can suggest,

I didn't know where to put this question, so I thought this would be the most appropriate. My computer (A macbook pro, with mac OS X, version 10.4.11) will randomly disconnect from the internet, mostly when I'm playing online games. Sometimes I can play for hours, other times only minutes before the next DC. I can restart and it will work for a few more minutes. The funny thing is it only does this when using the wired connection at my apartment, when i'm using the wireless at college it works fine. Part of my inquiry is checking if it's my computer or the ISP. None of my roommates have similar problems (though they all use PC's). One interesting thing I found when a tech from the ISP was trying to fix things is when I try to renew my IP it gives the same address after it "renews". I know I threw alot of jumbled info out there, but I'd like input from someone who knows macs.

I own a MacPro, running OS X 10.6.8. Several weeks ago it began to restart on its own, right after I turned it on. I ignored the issue and continued to work with it for several weeks. Suddenly yesterday it began to behave funky again, to the point where I cannot work with it at all. I turned on the computer, and few minutes later, it restarted on its own for several times. The point where it restarts is random, sometime in the sing in section (when you place the password) or while I work on some program. I was trying to run DiskWarrior, and the machine restarted on its own again!
I am also using part of this Mac as a PC, so I tried restarting on PC to see if its only on the MAC side, but it didn't make it through, it restart again before the windows icon appeared. Then after several restarts on the Mac side, an error message appeared, on the grey screen before the apple icon appears. It is all writen in code and it says something like: panic (cpu 0 caller 8x2aaf41): Machine check at .... (the picture is in my iPod but I don't know how to bring it into my computer). By searching this forum, I read I could try by reseting the PRAM and NVRAM, but I wonder what the consequences are when doing this. And if I try reinstalling the software, would I still be able to keep the PC side intact? Cause I still need to access the PC side as it is? I was able to run a backup for the Mac yesterday, but I couldn't for the PC.
