OS X :: Hard Drive Fan Speed Stuck At Max
Dec 1, 2009
Alright, here's the situation. Last week I shut down my computer to go away for thanksgiving, and when I came back and turned on my 20" white intel imac my hard drive fan sounds like it is going max rpm. I have istat pro installed and the rpm for the HDD fan is showing it's at zero. Does anybody have a clue as to why this is happening? My computer was working fine when I last used it but now my fan is going crazy. It's really loud and i'm concerned my the life of my fan. Any suggestions on what to do would be great. I installed Snow Leopard after the problem occured, but it's still happening.

I'm using Data Rescue III on a USB powered hard drive with and it's taking a very long time with my iMac G5... It says 42,291 hours remaining (about 5 years) If I did it on my Mac Pro would it go faster, or is the recovery speed based on the hard drive speed?

I've been looking at a number of different Firewire 800 enclosures to use with my new Mac Mini and I have seen lots of complaints with almost all the enclosures that I have investigated, including the Newertech MiniStack v3 which I thought should be a good one. A recent enclosure I came across that I haven't seen any bad reviews about is the Icy Dock (MB559UEB-1S). I'd like to know if others are using this and what they think about it. The next question has to do with the type of hard drive to put into the enclosure. Is it worth getting a high performance drive, or will the Firewire 800 interface be the bottleneck even with an average speed drive?

I have just received my new MBP 2.66. I upgraded my screen and hard drive to 7200. How do I check the speed of my drive. I have gone through all the usual places but can't find the speed anywhere.

Someone is selling me a powerbook, but I want to find out what the harddrive rpm speed is, they don't know what it is. Is there anyway to check using system profiler or something?

I spent two weeks obsessing on what type of drive to put in my new 8-core Mac Pro (january 2008). I was all set on spending $$$ and go with two 1-TB Samsung's but at the last minute I read this:
[URL] which posted better World Bench ratings than a 10k Raptor and is quieter than WD's Green drives - NewEgg had been out of stock of this brand new drive and suddenly got a batch in and I ordered two of these (WD Caviar 640 Gig / 16 meg cache w/only 2 drive plates). This drive is LIGHTNING fast....I've got before and after bench marks to post, I went from a 56.84 to a 102.91! Also, these installed so easily - not a single hitch!

Recently I bought WD6400AAKS hard drive. I made to partitions (1st for OS and applications, 2nd one for photo files). I also did fresh OS install and loaded basic applications. Strangely I didn't notice any speed boost while booting and to be honest I feel like all applications (photoshop for example) are also starting much slower than on original hdd. Is there any way to test hard drive if it performs as it should be? I also have 2 more older drives installed. is it possible that one of them would slow the system down?

I am wondering what was the stock hard drive speed of my PowerBook G4 12" (specs in signature). I am asking for the speed of the 80 GB ATA/100 HDD this shipped with.

About 2 years ago, I added a hard drive in the second hard drive compartment. I would like to replace it with a recently purchased 1 TB SATA hard drive that is desperately needed, but the hard drive in the second compartment will NOT budge whatsoever. I've tried wiggling the hard drive side to side for hours, bloody scratched up hands, screwdriver method Apple suggests, chop sticks that another reader suggested, even a string with a knot to no avail. I don't have rubber clamps as one reader suggested. Does anyone else have any other suggestions besides going to a store and paying them to remove it?

I own a 1st generation MacBook Core Duo (black) with 80GB Fujitsu at 1.5 Gigabit/s. I want to replace this with a compatible hard drive. Will this - Western Digital Scorpio Blue WD3200BEVT 320GB 5400 RPM 2.5" SATA 3.0Gb/s Internal Notebook Hard Drive - work in my laptop? I notice that it has a 3.0Gb/s speed versus my current Fujitsu 1.5Gb/s. I'm using Tiger, if this matters.

I know this topic has been gone over several times, but I'm still having trouble deciding on which to get in a new 15", 2.8Ghz MBP - 5400/500GB, or 7200rpm/320GB (or 500, really). I'll be using the machine largely for graphic design, but also for various other tasks as my main computer. I've heard the faster drive IS a noticeable difference, but it also drains battery life and runs hot. There doesn't seem to be a consensus on this anywhere. Is the 7200 worth it?

I am desperately waiting on the MacBook Pro refresh. I plan on buying my first MBP, a major upgrade from my grandma's iBook G4 I am currently using. I had a question about hard drive speed. I know that 7200RPM is quite a bit faster than 5400RPM, but what about battery life. I need it to get me through a day of school, 4-8 hours. My question to you is: would it be worth the extra $50 or so to upgrade to a 7200RPM HD, and what would the effects on battery life be? In your own experiences with current MBPs. I've thought about going with a SSD, but that might end up being too much, since I'm already paying quite a bit.

I know that the server version has a 7200 rpm HD, but what about the regular version? Also, is the 500GB upgrade HD on the vanilla model a 7200 version?

I have a new macbook pro and after reading various threads I want to buy a gtech 320gb external drive. The only one I can track down is the firewire400. (at a reasonable price) The MB is FW800. will the FW400 work OK and is the speed significantly slower?

I just switched out my 160GB hard drive on my 13" MBP for a 500GB. I do notice that things are a little slower now as far as opening up apps and such. Would upgrading to the 4GB of RAM instead of the 2 I have make a difference or is that the trade i get for running a 5200 500GB HD.

I have an early 2009 macbook, with 320 GB hard drive and running OS Lion, after i upgraded my os to lion, the computer ran perfectly normal, although a little bit slower than running snow Leopard. However, recently I notice my mac become very slow, got rainbow wheel even when i open the safari. then I use the black magic to test the hard disk speed, it appears the read and write speed is only a little over 30mb/s.
i have recently change my keyboard at apple store, I notice my mac slow down after that, do you think it would related?

I have an old (late 2006) 20" iMac. Problems started a few weeks ago - first the computer would freeze and crash. Eventually I started getting either a circle/slash sybol or the question mark folder every time I tried to reboot. Eventually I concluded that the hard drive had gone bad. So I bought a new 1TB Barracude from OWC and installed it following instruction found on [url]....
Now I can't do anything. I tried booting from a OSX 10.6 install disk, but the machine simply spits it out after about 30 seconds and gives me the "?" folder. So I got my hands on 10.4.5 Universal Install disk and tried that, thinking that maybe the older machine needed an older version to start from (sounds logical at least). Nothing. It doesn't spit that one out, but still ends up with the flashing "?" folder after a minute or two. I've tried holding down C on startup. Same result. I've also tried holding option to get the startup manager, but that doesn't work either. I just end up back at "?". I really hate "?"

I have an old white Macbook, the 512 Ram, 60 GB Hard drive model, 2.0 Ghz. I'm currently upgrading my Ram to 2 Gb, can anyone recommend a relatively inexpensive model replacement for the stock drive with good speed. I'm currently shopping on Newegg and I have no idea what I am looking for.

At times my iMac (27" July 2011) starts making loud fan noise with mouse showing turning rainbow. The only way to stop is forced shutdown by pushing back button for a while. Yesterday I switched to widget screen and saw hard drive fan speed > 4000 rpm without CPU and temps by on the high side.

I'm getting ready to sell my old Powerbook G4 so booted up from the installation CD, and ran Disk Utility to do a 8 Way Random Write pass on the Mac hard drive before I did a clean install (the disc is Mac OS X 10.3.7).
I selected the top option in the drive panel of Disk Utility (the one saying 92.2GB Hitatchi blablabla) rather than the indented disk beneath it.
All went fine doing the overwrite, however it seems to have become stuck on "Creating Partition Map" - it's been like that for half a day now. Any thoughts? Should I have chosen the indented drive underneath the main description?

I tried reformatting while running Snow Leopard, but the option was grayed out and the install disc made the computer hang at the white bootup screen. I figured I'd just upgrade to Lion and do a clean install (not an option).
After upgrading to Lion, I booted into recovery to erase the hard drive. I did it and it took less than ten seconds (bad sign).
Now I can't get past recovery and the hard drive is still full.

I recently bought a new macbook pro which I had set up and was running just fine. I then switched my hard drive from my old macbook (2006 black) which was running snow leopard. The Macbook pro will not move past the apple logo screen while the macbook starts up and willingly installs snow leopard on the new hard drive. I switched them back hoping that the macbook pro would recognize its old hard drive but no luck. I have a feeling its the old software as i read some where that you should not install older software on your mac than what it came with.

I upgraded the ram to 4gb crucial on my 24" intel imac (early 2008). Now it freezes at apple screen, but only if my external WD My Book hard drive is plugged in via firewire. If I unplug it from the firewire port.

I recently picked up a 17" 2009 unibody MacBook Pro with Intel Core 2 Duo 2.8ghz, 4gb RAM, SuperDrive and a Samsung 1TB hard drive. The system did not come with the original hard drive and I don't have any other hard drives to test and verify that the new larger hard drive is the cause. I have tried a clean install of Snow Leopard, Lion and even Mountain Lion but no matter what my fans always running at max speed (5k+ RPM). I have looked at iStat and the temps of any of the components in the machine never show more than 42*C so the fans should never be running at full blast. Oddly enough smcFanControl shows 0* temp but fan speds for both left and right are always 5.5k+ and very noisy. Using HDD Fan Control I am able to get at least the right fan to run at a controlable speed but its silence is drowned out by the left fan that still runs on full blast. I have already done multiple SMC resets and PRAM resets with no change in the condition. These noisey fans are driving me insane! I have run every available update as well. Is there a chance that the hard drive or something elses temp not being supported or detectable by OSX is causing the fans to default to the fail safe constant high speed?!
