Mac Pro :: Periodic Humming With New 1TB Seagate Barracuda
Mar 14, 2009
I just purchased 2 1TB Barracudas and upon installing them (bays 3 and 4) I noticed a faint but definitely audible (and aggravating) humming noise that comes in a cycle of about 5 seconds.
It sounds identical to this video (made by someone else, but with the same drive) but my cycle is a bit longer:

I'm wondering if this is an issue with the drives or my installation? I mounted them tightly. I tried staggering the new drives with my old drives in terms of bay order to no avail.
Has anyone experienced this? The price on these drives is killer ($129) but I'll be returning them soon if I can't kill this noise.

Is anyone having trouble with the above drive since the update?
I'm using it (Barracuda 7200.11 - 1TB) to house my home directory on my MacPro 2008, in one of the Internal Bays. Since the update I'm having trouble with folders and files going missing, countless freezes, preferences going missing, Time Machine dying.... it's practically crippled my Mac. A couple of times on restart it's failed to see the HD with the home directory on it, so, power down... restart... and everything has magically returned to normal.
The occasions it has worked I've checked out it's status using TechTool Pro 5 and it says everything is fine. 2 mins later - freeze.... restart.... I've tried the combo install. No joy.
The drives are only a couple of months old.... someone tell me it's not just me!

Which one of these 500gb drives is better? I've been browsing Newegg for two hours now reading reviews. The Seagate drives seem to come with bad firmware that causes performance and cache recognition issues. The Samsung drives have a high failure rate. Whats the real deal? Has anyone here had any bad experiences with either drives?

I think I have a slight issue with my 7200rpm 500gb seagate drive. Once or twice every hour it seems to stop and start up again. Kinda klicks. It causes my computer to freeze for about 3 seconds. Whats causing it? Is it faulty? I should also mention that it didn't do this when i first got it. This is the model without the SMS.

I have a new wk 11 MBA 1.6/80g. I've been reading threads on CPU heat and core shutdown. I'm trying to decide whether I need to return my sys for an exchange. Other than heat/shutdown issues my MBA is awesome. Excellent fit and finish, no dead pixels, lid alignment is perfect, etc. When playing HD vid at full screen with my desktop background randomly changing at 5 sec intervals the vid stuttered some and I saw one of my cores intermittently shutting down. However, I learned to stop the stuttering by making my desktop background static. I was thrilled. I could overload the system with two vids playing simultaneously and watch my core temp go to 84/85C with some stuttering on the vids and some intermittent core shutdown. Finally the temp settled to mid 70's. However, I later noticed that I was having periodic core shutdown at 69C. This seems way low for a core to be shutting down.
Ambient temp for my room has consistently been 70F through all of my tests. As I type this message my core usage is very low, temp is 47C. My activity graph shows intermittent periods of both cores having no activity. How can the graph show no periodic activity on each core while I type this? I thought core shutdown was when the core shows no activity for some period of time. Perhaps periods of inactivity which really indicate core shutdown could be different as compared to very low demands on the CPU's? But, am I misreading core shutdown? Is my unit defective? Is excellent fit and finish/build quality the norm for MBA? I don't want to exchange and have dead pixels or a warped lid, etc. I would rather open the unit and mess with thermal paste but I can't see it correcting core shutdown at low temps under heavy load. I purchased this MBA on Saturday.

For about two weeks I've noticed green vertical stripes appearing on my early 2008 MacBook Pro. As you can see the photo below, it doesn't completely obscure content on the screen. The problem is also transient. It appears, sometimes as a flash, then disappears. In the picture below, the issue continued for longer than ever before (about 1 min). Is my video card about to die? Could this be a bad connection?

I have a 2008 MacBook Pro 4,1 (15-inch, Early 2008, OS X 10.6.8), that has started locking up periodically. Initially the lockups occurred every couple of days, now they are becoming more frequent, yesterday it happened twice. I am able to move the mouse, change applications via the Dock, but can't close applications. I can't trigger reboot, I have to manually hold down the power button. I've disabled Intego, and run a full memtest scan to see if the RAM is crapping out. ...however there is no EFI update for the 4,1 series.

I bought a 13" MBPr starting February, yesterday (Thursday 21) it started making a "clicking" noise on the right side of the body it's periodic and constant it is only hearable when the lid is open and the computer is turned on, it seems to be emitted from below the right side of keyboard the noise is quite loud even with other sounds in the room.
I haven't tried any fixes as it seems to be hardware issue.
Here is a recording of the sound (Ignore the dog bark and bump noise at the end of the recording): [URL]

At the time it seemed very practical to use a Time Capsule to share files between the members of the company (we are just 4) and this way use it as backup and server.
As we use it as the company file server to share file between member, we found out that it would be needed to make backups every now and then (preferably on monthly basis).
I bought another normal external hard drive, plugged it into the time capsule and made the backup.

I replaced my main drive, the 320GB with a 750GB Samsung F1. It seems to work fine. However it seems to have set up some sort of sympathetic vibration in the Mac Pro, which sounds like Hummm Hummm Hummm. Where as all the other things that cause noise in the case are a consistant and steady tone, this one is not. It's driving me nuts. Is this normal to be making this noise? I've tried it in different bays and it makes no difference.
UPDATE I've taken all the drives out except the F1, as I installed another DVD drive and three HD's and the noise has gone, so I'm now going to load each drive and review.

What causes a harddrive to make a humming type vibration. Is that a drive getting old and need to be swapped? its annoying because my mac pro tower is silent otherwise.
The noise started about a month or so ago but I had this drive for a few years now.
If the machine is on after it was a sleep for about an hour the noise dissipates a little.

Last week I recieved my 27" iMac i7 2,93GHz with the 2TB Hitachi Drive.
I ordered this drive because it was said in this forum that this one should be silent.
Now, during access it is not really silent, but thats no problem
What bothers me more is, that there is a permament silent hum. An I can fell this vibration even on the stand (hopefully this is the correct term, I am from Austria, so english is not my native language).
And this vibration is also forwarded onto the table, but it is not really feelable on the table.
So my question is: Some say that their iMac is "dead silent". Mine isn�t, I also can here the fans silently, but that doesn�t bother me either. But this humming is somewhat distracting or annoying.
Maybe I am just to "picky", but do you really have iMacs which are almost inaudible?
Because I do not have any other problems I am not sure whether I should ask for a replacement.

My Mac Pro 8 Core 2 x 2.8 GHz Quad-Core Intel Xeon with Leopard 10.5.8 started making a humming noise about a month ago. The humming noise is very consistent in pitch and is always humming whenever the computer is on, except for when sleeping.

My new iMac 27" (i3, 3.2GHz) is not so quiet as my previous iMacs -
I can hear a low humming noise! Not very loud, but I don't like it.
It grabs my attention...
It sounds like a fan motor or a transformer.
I can also feel a corresponding vibration.
Is this normal now? Does anyone else have this problem too?
Would you recommend to return/exchange this iMac?

After returning 4 21.5" imacs with yellow screens and hard drive noise, I decided to try a 27" and finally a beautiful screen with no problems, no hard drive noise. I was very happy...untill I started hearing a humming noise that sounds like it is coming from the power supply. The noise stops when I put it in sleep mode. I tried a bunch of things to determine if it was the fans or hard drive and that was not it. I am pretty sure it is the PSU humming all the time. This is the first imac with a perfect screen and now it is humming. I am so frustrated.
What should I do? Have the power supply replaced or return it for another one and take the chance of getting one with a yellow screen? I am still within my 14 days of original purchase date.

My Powerbook G4 recently started doing the HD clicking and squealling noise. So I changed the HD and everything worked great for about a day. Now there is a new Humming/Ticking noise coming from the area where you plug the power supply in.
If i tap in that area, it will go away for a couple minutes and then it comes back again. Sometimes it will just go away on it's own for a few minutes too. It doesn't change if I unplug the power or anything.

I bought iMac 27" from local apple store two days ago. Everything is fine execpt that there is some weird sound coming from the computer when the screen turns darker to save energy. Once I move my mouse to activate the screen, the sound goes away. I am saying the sound is so load, but it is still noticable and a little annoying in a quite room.
Update: I search "screem+humming+dim" and turn out actually a lot of iMac owners have this problem. Is it a technical issue Apple fails to resolve in general?

Yesterday I started up my MacBook Pro that I've only had for about 9 months. I immediately noticed that there was a barely audible buzzing / humming sound coming the inside of the laptop, most likely in the fans. I don't know how long this has been going on, and I really don't know the cause of it. So is this something I should be worried about (the sound is barely audible)? Or is this something that happens after prolonged use of the laptop?

There is a new humming sound coming from my parents iMac, I think it's the processor cooler but I'm not sure. It could be the hard drive as well, I just know it kicks up sometimes when there is a lot of activity. The problem is they don't do a lot on the computer so it scares them.
They are convinced that it is going to die because it's soo old, I think under two years, but this is the second computer they owned. The first was the first 20" G5 iMac that, instead of turning it off the correct way, they just unplugged from the wall outlet. Needless to say it died, but they think it was because their son in law used it too much. I try to tell them that it's because how they turned it off, but they didn't like their son in law, who is now an ex-son in law, so they blame it on him. Yes, I know, my parents are the last people to own a computer.
They also don't want to spend any money on their computer, so worse case scenioro, taking it to the Genius Bar without this computer being under warranty and having them replace the processor fan and/or the hard drive, what would it cost? I think it might just require a new fan for the processor cooler, but what if they need to replace a lot more?

..by the power unit at the back of the machine - where the power cord goes in.
I happened to be switching out displays at the back of my MP today. Could hear the fan at the lower back portion of the machine (as normal). but this time could also hear a very slight electrical hum just by the power unit -- is this normal (the hum) does yours have this hum?
I never heard it before. guess my head was never that close to it when the MP was on the floor. but since i moved it to the top of the desk my head is closer to it when I switch out the DVI ports
Trying not to be obsessive. I'll run before the white coats turn up by the front door

I purchased a 21" iMac a couple of months ago. Today it started making constant buzzing/humming noise. It's not really loud, but it is noticeable and annoying after a while. It stops if I put the computer in sleep mode or turn it off, but it starts back up the moment I turn it back on again. It sounds like it is coming from the bottom of the screen near the speakers. I have tried adjusting the brightness and volume, but to no avail. I also tried lifting the computer off the desk to see if it was just vibration, but that did not make a difference either.

I have a 2006 White Intel Imac and I recently replaced the Superdrive with a non apple Panasonic Superdrive Model: UJ-85J-B from a used Acer Laptop. The replacement drive has no sensor circuit board. After putting it back together there was a loud humming noise and I assumed it was the new drive but when I took it out and started the Imac without it the noise remained? Now I am thinking it is the fan just below where the Superdrive sits? I blew out as much dust as I could from this fan and around the bottom of the case and that made the noise just a little less annoying. It sounds like it is about to take off like an jet airplane?

There is a loud and really annoying humming & static noise when I connect my charger to my MBP. The humming only comes out of the headphones jack, and not the MBP speakers. This really cripples me in my work as I am a music producer.

I've had my imac for under two years, and just recently I noticed it making an odd humming/buzzing sound at times. It's not the normal sound you hear when your hard drive is working hard, it's definitely different. It's not the speakers either, it happens whether they are on or muted.
My suspicion may be that it has something to do with the power. That's because I've been bug testing a mac beta game, and it often crashes my computer, and I have to manually turn off my computer by holding down the power button until it cuts the power.
Does anyone know why this may be and how I can prevent it/fix it?

My 20.5 inch 2.7GHz iMac is about a year old and has recently started making a low humming/buzzing noise from the top right corner, near the SuperDrive bay. The top of hte iMac feels quite warm when it makes the noise and usually stops if I hold my hand on top of the computer. Is this something I should be contacting AppleCare about?
