Replacement HD spinning up and down during "sleep"

I just "upgraded" the HD in my iMac Indigo to a 40GB Western Digital. Everything runs fine (things I have tried) except that it won't sleep properly. When put to sleep, the HD spins down, stops, then after a brief pause spins up again, leaving me with a blank screen and a spinning disk. Thereafter I get noises of half spinning up and down at intervals.
I have seen bad comments about Western Digital and one problem where resetting was required (PMU?) Do I have an unhappy HD?
I started up in 9.2.2 and put it to sleep and it slept properly. Does the HD just not like OSX? I'm running 10.3.9 on the Imac Indigo 350.
Any thoughts please? Thanks in advance.

OK, answered my own question (via Duane on another post). Looking at Duane's link http://forums.xlr8yourmac.com/drivedb/search.drivedb.lasso I found the exact same problem encountered with WD drive elsewhere, hence solution-send drive back and get a more compatible one (looks like Maxtor). I'll leave the post up in case it helps anyone else.
Thanks Duane

Hard drive constantly spinning up and down when asleep

Hi all,
I have a problem with an external USB 2.0 hard drive connected to my Mac mini (late 2012).
When I put the computer to sleep the drive spins up to speed, stops, then immediately starts to spin up again. This goes on and on.
I understand that drives will periodically spin up when asleep for spotlight indexing etc. However this seems like strange behaviour, it just repeats spinning up and down in an endless cycle.
I have had the drive for a while now, as my time machine backup. Interestingly this problem only started after I rearranged my desk when I set up a second monitor. I have a USB 3.0 drive (my scratch disk) that behaves normally.
I have drives set to not sleep in preferences.
I have searched around but can only find posts about people not wanting to wait for drives to spin up when they open finder etc.
What do you think? Could the drive be on its way out? It is a Samsung spinpoint f3 1tb in an Iomega enclosure, for information...
I appreciate any help,
Cheers,
Mike

Hi BDAqua,
I should have noticed this earlier but it appears the problem is with the mini waking from sleep and thus causing the drives to wake.
When I put the mini top sleep (without the external drives powered on) it constantly wakes and sleeps. The displays dont come back on (untiul you click the mouse or hit a key etc.) but you can hear the internal drive spin up and the sleep light comes on, then goes back to blinking until it wakes again.
I have realised that it must be due to the second monitor that I have connected via the mini display port. It is connected using a mini display port to hdmi cable I bought from play.com. Something to do with the display and thunderbolt is casuing the sleep function to misbehave, I think.
Here is the console log that was created after sleeping the mini, allowing it to go through its weird sleep/wake cycle then fully waking it up again.
Hope that makes sense, it is late and I am tired!
Thanks for all your help.
Mike

Mac Pro shuts down during sleep

My Pro sometimes shuts down during sleep. Nothing will wake the machine and it it not accessible by another other computer on the network. It has to be manually re-started using the button on the back of the computer. There are no error messages on re-start.
I have reset the SMC and PRAM but it makes no difference.
Any ideas?

Perhaps some third-party software that you had previously installed needs to be updated to be compatible with the latest OS X updates.
Perhaps some hardware component is experiencing problems; even the best hardware fails occasionally.

Spinning up and down lots, is this healthy?

Hi there,
I've had a TC Dual Band (500GB) for a few months now. I'm really pleased with it (except for the slight niggle I could have 1TB for the same money, lol)...
My only worry is that the hard drive spins up and down a lot. It does one machine's backup, then after about 5 minutes it spins down. Then another machine needs a backup, and it's spinning up again within a couple of minutes (it's sat on top of a side unit and makes the whole unit hum so I can hear it quite clearly!)
I always thought that it wasn't good for hard discs to spin up and down a lot because they wear out more quickly... Is it something I should be concerned about, am I going to have to replace the hard drive sooner than I'd expect?
Thanks!
:-Joe

...and you don't have your old gpu?
You do realize that not all PC cards play well, and that you read up and researched before setting on this one? even different versions and makes of the same "model" or card series differ.
AMD cards may have two BIOS, legacy and UEFI.
Thought about sending it to MacVidCards or checking?
AHT does not test GPU.

Stop external HD randomly spinning up and down

Hi,
I have just bought and installed a LaCie P'9230 2TB external HD to use as my Time Machine disk. I was previously running Time Machine just once a day to an iOmega disk, which I would switch on only when I wanted to run the backup. With the new LaCie, I thought I would leave it on all the time and use Time Machine Editor to program Time Machine to run twice a day.
The LaCie works fine, and Time Machine runs twice a day as scheduled. However, the LaCie will go into "Eco mode" after a few minutes of inactivity, and then go to sleep. This is fine – I would be quite happy for it to go to sleep and stay asleep until Time Machine wakes it up twice a day. The problem is that something seems to be waking it up every 15 minutes or so, causing the disk to spin up. It then goes back to sleep again after a few minutes, and the cycle continues. Note that this happens even if I'm not actually doing anything on the machine at the time – in other words, it's not caused by me opening or saving files, running searches, etc.
I know that constant spinning up and down is a major cause of early HD failure, so I'd like to find a way around this. Ideally, I'd like to find a way of letting the disk stay asleep until Time Machine wakes it; failing that, I'd prefer it to stay awake all the time and not go to sleep at all. I've tried unchecking the option in Energy Saver to "Put the hard disk(s) to sleep when possible", but this seems to make no difference – presumably because the Eco mode/sleep function is baked into the LaCie firmware and cannot be overridden by the OS.
I've spent ages trawling the interwebs; I've found is that this seems to be a common complaint, but haven't found any definitive answers. Really hoping someone on here might have some insight and/or suggestions.
Thanks,
Rob

This may be a "feature" built into the firmware of your external drive. If so it will not be affected by your Energy Saver settings. I recently had to advise someone with a "Western Digital MyBook" spinning down to ask the manufacturer for help, but the outcome was that the only solution was the purchase of an uncrippled drive. Being in the firmware, the "feature" could not be erased or altered.
"Is it possible to stop…"
Yes, but only in what I would consider an unacceptable manner, e.g. by having a small script that constantly accesses the drive, but I would suggest that a) it should not be needed, and b) it would be highly likely to interfere with other things you were doing.
So, as a start, you should a) read any docs that came with that drive, and b) go to the relevant site and see what you can find out.
I hope that none of this applies to you, but I just thought you ought to be aware of the possibility.

USB Hub makes Airport Extreme HDDs constantly spin up and down

Hello there,
I have a new Airport Extreme, (newest model, but not a time capsule). I have discovered that when I plug an external USB HDD into the AE, everything is dandy. But when I use a powered USB hub, the HDDs are constantly spinning up and down. All connected computers are shut down. Nothing is accessing the AE. From my testing it seems to be the powered USB hub that is creating the issue. Has anyone else noticed this? Could it be my hub (Amazon Basics 7 port powered USB hub)? Anyone have any success with a different hub?
Thanks all!

It can be a whole lot of stuff interacting.
What are the external disks you are testing with.. as that is just as important as the hub.
I have not had issues using hub.. but I seldom try it.
Powered hubs of low quality (ie standard cheap end, rebadged made in China junk) can have substantial issues with power leaking.. ie it sources power from its own supply or the AE or the drive..
Let me suggest you test one at a time.
Plug in just one disk.. (will the hub work without the power supply plugged in.. some do).. assuming it is not a self powered drive.. see if it is ok by itself.. test each drive.. with the hub powered and unpowered.. tell us what you get.

Volume changes up and down during all solng

Every time I listen to songs, the volume goes up and down and up and down again.. Anyone know why - and more important, how to fix it? Thanx..Anne

I have observed this effect on all systems I have run on with the exception of my work computer (running windows 7). Even on my laptop (also windows 7) as well as my home pc (ubuntu) -- this effect is noticable. I have the premium membership and always felt this was a spotify issue because no other programs experience this effect.
I originally thought it was a priority issue. Setting spotify to HIGH or realtime priority had no effect. I attempted all other solutions on this thread and the effect is still very noticable. I suspect spotify limits bandwidth during times of high volumes of data transfer. My suspicion suggests to me that they vary bandwidth and therefore the audio quality of your playback. Youtube, netflix, pandora, and other streaming media companies are known to do this with media quality.
Software is developed by companies to detect your network capabilities, and scale the quality of your media based on these factors. When your connection is terrible, or your bandwidtch drops, the quality ofy our media automatically adjusts and scales in a manner that appears to be diredtly proportional to your networks attributes.
My assumption is that at work (windows 7), our T1 line is so fast that bandwidth is never an issue -- so audio quality is always the best. When I take it home, due to router limitations and ISP limitations, my connection is not nearly as reliable and consistent.
These are my suspicions and I am very technologically literate, and have done much research into coming up with a solution to this issue. I feel it outrageous and offensive that I can purchase premium membership and pay a monthly fee to have my media quality automatically adjusted based on network attributes. The option to pause for 10 seconds to buffer the song would be preferable over lisening to a song that varies tremendously in volume.
Spotify, I love the concept of your service, but it appears your money saving techniques effect the quality of the experience your a providing - and people will know.

MBP shuts itself down during sleep

My MBP shuts itself down durning sleep... or, stays black when I open the lid after sleep. The hard drive is on, but no key pressing will get it running. I have to hold down the power button, til it clicks off; then press it again to boot up from scratch.
Today, I booted up Console and under messages found this:
7/28/12 4:56:21.519 PM Firewall: Stealth Mode connection attempt to UDP 192.168.254.1:64508 from 192.168.254.254:53

7/28/12 4:57:07.000 PM kernel: macx_swapon SUCCESS
is this the signature of Trojan?
How do I correct this?

I'm having almost the same problem and I can't figure it out either. I put my computer to sleep and when I wake it up, the screen comes on with my full desktop, but everything is frozen. I can't open anything. I can't even force quit. I get no response from my mouse (other than being able to move it around- sometimes) and everything on the dock is unresponsive. I did disc repair– no problems reported. I repaired disc permissions– a few glitches, but all taken care of and okay. I restarted the computer, put it to sleep and same thing all over. Should I worry?

1st Gen iMac G5 doesn't turn on--after shutting down during sleep

So I bought an IMAC G5 17/1.6/256/80/COMBO when they first came out. Within the first year and a half I had to get two logic boards replaced. Fast foward to about 4 months after Applecare ran out and the machine began shutting down instead of going to sleep. Then, last week--nothing--wouldn't even turn on. So I unplugged it and plugged it back in and it started fine. Two days ago same thing only now it won't turn on at all. So I took off the cover, internal power button doesn't work--tried reseting SMU and still nothing. LED 2 doesn't come on at all, but LED 1 isn't constant, it flickers (don't know if that's normal). So I assume it's either logic board or power supply.
Now, I've read the Repair Extension program about this model, but unfortunately it only goes out three years (curious because that's how long my AppleCare lasted). And I found it odd that after getting it fixed twice it would still have these defective parts. So I called the support line trying to explain the situation. After being on hold for 20 min. the guy came back and said my warranty was up so I couldn't even talk to someone on the phone about the problem. I could get it fixed, but it was going to cost me.
Anyone have any advice? I was going to get another computer later this year (although will probably change my mind about getting another Mac after this experience), and I know fixing this one will be pretty expensive--something I can't afford right now. Does anyone know the rationale behind a) three year cutoff and b) Apple not informing owners that they'd better get it checked out before period runs out. And I guess as a last resort if it winds up being too expensive to fix, anyone know if people buy broken IMACs? Talk about frustration, I didn't even have to go through this type of nonsense when I used Windows.
Thanks for your help.

Welcome to Discussions - try calling Apple Customer Service 800-767-2775 and politely telling them your tale, then ask for a fix or a new computer.

Shuts down during sleep.

so the other week my imac started doing a funny thing. either i'll put it to sleep, or it will put itself to sleep after a period of time; but when i return to my imac it has shut off. it isn't responsive to the keyboard, mouse, or power button. the only way to reset it is to manually unplug and replug it in. when i turn it back on, all of the fans spin up (loudly) and it takes far too long to finish booting. it remains at the gray screen for several minutes. i zapped the pram. reintalled the original os (panther). nothing seems to be helping. i read in a previous post about several imac owners having similar power issues, but my serial number doesn't match the power supply issues that apple has covered. its no longer under warranty, considering i got it when it came out back in november of 2004. everytime i have to wait 10 minutes for me computer to boot up i get more and more irritated and lose more and more respect for apple (not that i'd ever conseider going back to a pc). please help.
iMac G5 Mac OS X (10.4.5)

Hi there,
Welcome to Apple Discussions.
Sorry to hear of the problems you are having. I presume with all the other things you have tried, you have verified and repaired permissions and run something like Cocktail or Onyx?
Are you sure your serial number doesn't fall within the one's Apple offered an extended warranty on? The reason I ask is because I bought mine the same time as you (Rev A) and I too had sleep issues, amongst other things, with my G5 iMac. Instead of going to sleep it would restart. I rang Apple and I was still within the warranty period (just)and after going through a whole load of their suggestions - like the one's you have already done, they gave me a number and said to take it into an authorised Apple repair shop.
I did this and it turned out to be both the Power Supply Unit and the motherboard. Both were replaced under the extended warranty. It does sound like you are having PSU problems, can you take it to a repair place and just get it looked at?
Sorry not to be of more help, perhaps someone else will come up with more suggestions.

Shutting down during sleep

My new iMac 21.5 is shutting down every time it goes to sleep. This is my second iMac as I replaced the first one that was doing the same thing!
Any ideas? I have an airport extreme, two WD hard drives and a USB HUB atached. All are plugged into a brand new APC surger protector/battery backup 450/4550.

I suspect your problem is one of the peripherals. You need to eliminate the peripherals one by one to see which is causing the problem.

My Mac Pro Shuts down during sleep

Well I have a variation on what others are experiencing with their machine.
1- I put the mac to sleep. Or it goes to sleep when i's supposed to.
2- I let it sleep at least a few minutes…
3- when I press the space bar, the following happens:
- the mac responds immediately (see below)
- the fans kick in just as when you start it from shut down with power button
- the startup screen appears and everything after this point is the same as a cold boot.
I'm puzzled, but this is more an info message than a call for help.
My setup:
2.8 GHz 8 core Jan 2008 mac pro.
4x2 GB RAM from OWC (667 Mhz)
2x1 GB RAM (factory) reseated to follow the RAM arrangements guideline.
8800 GT video Card.
4x 750 GB Seagate drives. formatted as two RAID 0 pairs. One of the two holds the OS and apps.
The only other thing present is the OWC/Newertech S-ATA adapter that essentially brings the 2 unused SATA ports to the back of the compouter. Nothing is plugged to this for now.
Software:
OS 10.5.2 ans all updates applied.
for the moment the only non-apple app installed is the temperature monitor suite.
Hope this tells something to others. Will send this info as "feedback" to apple.

Ok so my g5 died...still complaining. Should have had apple replace it while still under apple care.
Had to buy an intel mac which has limited compatibility but is fast, durable.... i doubt it. I was sold on the g4s before i switched to apple. Never owned one bought a g5 to switch from pc for audio recording. Durability was my goal, didn't think i would ever need mac pro.
Mac pro reboots after it has been asleep. This is not a ram error. It is a design flaw. Their are many things that cause sleep issues which seem to be very complicated. This problem is sold with your mac.
The first thing i did before i even opened the box was read apple discussions on this issue and other bug reports. There are lots of reports on this particular issue as i was familiar with it the first time it happened to me which was maybe the second time i put the computer to sleep. To be honest why there hasn't been an immediate bug fix is disheartening. All i got to say is typical. I think i will be having some very stern words with apple tomorrow. Over all dissappointment in all departments regarding apple- durability, compatibility, backwards compatibility, customer support, and their inability to stand behind their flagship machines. I guess they're just a second rate circuit city brand. This is not only a rant.

"Moo" = Right fan repeatedly spinning up and down under certain conditions

I am pretty certain I have figured out what is causing the "moo". Here is my theory based on a couple of weeks of experimentation...
It is the right fan starting up and stopping. Again..and again...and again. It does this in response to temperature changes. But the threshold is too sensitive so what happens is an increase in temperature triggers the fan, the fan winds up and in so doing after a couple of seconds this immediately drops the temperature below the threshold and so the fan winds down. The temperature now builds and after a couple of seconds the fan spins up again. It will keep doing this until either activity falls so that the temperature stays below threshold or continuos activity ensures the temperature stays high enough to keep the fan on at low speed (when it is generally quiet unless there is a heavy load).
I will guess the cause is probably a faulty sensor, faulty fan or most likely faulty fan control logic since this is clearly happening with a lot of MBPs. If it is the latter then presumably they need only change the firmware controlling the fan to make it start slower and stay on longer.
Why doesn't everyone hear it?
a. Like most fan type noises they are only apparent in a quiet room - as most people work in rooms full of white noise they simply will not hear it even if it happens.
b. Some people have better hearing and are more sensitive to noise.
c. It needs the right set of hardware and sofware activities to trigger the problem...............
In my particular case I typically have my 2.0ghz MBP connected to an external monitor, ethernet and external USB mouse on the right side of the MBP. When I am using the MBP standalone (ie without more heat being generated) the noise does not occur as often, presumably because when idling less heat is generated.
As you change what you are doing with the machine (not sure if its CPU or Video related changes that matter most) the noise will start or stop happening. Doing absolutely nothing typically means the noise does not happen so often, but then again it can be sitting doing nothing and it will start happening. Doing a bit means (say 10-30% CPU) means it will make a noise , doing a moderate amount (say above 40% CPU) means it does not happen because the temperature stays high and the fan stays on - generally being quiet at low speed. If you push the machine (say 80% CPU) then a louder fan noise is noticeable. I have also found that opening/closing the lid (when using an external monitor) makes a difference, the surface it is on makes a difference and the room temperature probably does as well.
A good way to experience this is to start Garageband recording the noise when it happens since the additional load stops the noise. The spin up/down cycle will continue for 4 or 5 cycles as you record the noise but then the fan remains on very low speed as a new higher thermal equilibrium is achieved.
For reference I am on my 2nd MBP (the first also had this problem but it was less noticeable) and have experienced most the other noises:
a. Left Fan always runs on both machines
b. Screen buzz when not on full brightness on 1st MBP not in on 2nd.
c. CPU whine was not on 1st MPB but it is on the 2nd - but only at low level and only if running on battery power.
I have a couple of other irritating problems:
d. Screen dims after 2 minutes regardless of power setting etc.
e. Fit of 1st MBP was great, 2nd not so good.
Personally I find the fan spinup/down noise very very annoying, far more so than the left fan always being on. I really do need Apple to fix it, but I dont see the point of sending the machine in unless they recognize the problem and have a systemic solution since clearly this is common problem. Otherwise the chances are a tech will plug it in standalone in a noisy repair shop, hear nothing and either do nothing or never know if its fixed or not. So far no intelligent response from Applecare......If I can figure this Apple ought to be able to and get a fix.
And no I would not recommend buying a MBP until this problem is fixed if you are at all sensitive to noise and work somewhere quiet - because it appears to be a gamble as to whether you will get a quiet MBP or not. That's a shame since otherwise its a very slick machine.

I agree with u; however:
-The left fan that's always on is the Hard Drive - listen to the hard drive to the left of the trackpad and you'll realize that it is coming from there.
-My "moo" sound comes from my LEFT fan. So if it's a firmware issue, why would the side of the fan affected by the problem varry? this leads me to the worrying assumption that it is a hardware issue...If this is the case, who knows if apple will even cover it under warranty if it doesn't affect the performance of the system...

Mac shuts itself down during sleep.

When the Mac goes to sleep, it shuts itself down instead. This occurs when the machine goes to sleep automatically after a period of inactivity, and also occurs if sleep is selected from the Apple menu. Shutdown occurs immediately upon sleep, or sometimes after being asleep for a while.
When the Mac is restarted, no error message appears (the one which says that power was lost unexpectedly, and prompts you to run disk first aid).
The problem occus on most occasions that sleep mode is activated, but not every time.
Any help towards fixing this problem would be much appreciated. Thanks.
PowerMac G4 Mac OS X (10.4.6) mirrored doors

I'm having almost the same problem and I can't figure it out either. I put my computer to sleep and when I wake it up, the screen comes on with my full desktop, but everything is frozen. I can't open anything. I can't even force quit. I get no response from my mouse (other than being able to move it around- sometimes) and everything on the dock is unresponsive. I did disc repair– no problems reported. I repaired disc permissions– a few glitches, but all taken care of and okay. I restarted the computer, put it to sleep and same thing all over. Should I worry?
