Boot drive access/noise...normal?

Greetings again.
Been using my new MP for a few days now and it's great, but have noticed something along the way I'm curious about.
My Boot system drive seems to be constantly accessing, even when not doing anything. I can hear the sounds (seems like the normal "soft grinding" noise they can make when writing - i don't want to say it's clicking or thumping). It seems to happen a lot. If I open activity monitor and view the active processes it changes by the second, so it appears that this is just something the system does. Oddly, the drive seems to make less (smoother) noise when writing large files.
It's noticeable when doing nothing or doing small things like running the screensaver, or even typing this post.
Considering having a number of drives in the past, it doesn't sound alarming or anything but is noticeable. I have a second external (same kind) which seems to be much quieter when writing.
I just wondered if anyone else experiences this, or if it's normal or sounds like something I should be worried about? I verified with DU and seems okay.
Otherwise, thank you, and I'll enjoy the machine.

The Western Digital drive in my 2009 Mac Pro started making the same noise after beeing very quiet the first couple of days. It lasted for a week or so but now the noise is gone. It could be the S.M.A.R.T system in the disk is doing something to the disk. But I'm no expert...

Boot drive access locked

My boot drive has become locked (now a folder with a red minus mark instead of a drive icon). In get info it says "you have no access" System and admin are listed as having no access. Can't change these. Is there a terminal command I can use to fix this?

Run the following from the Terminal:
sudo chmod 1775 /
Provide your administrator password when prompted; nothing will appear in the Terminal window.

Is there a way to access purchased apps from the app store on windows computer? For USB boot drive

Having a problem with my Macbook (13", Late 2009 I believe) after attemption to update iOS to OS Mavericks. Have run into the grey screen of death, and have almost exhausted all options, including reseting pram, accessing fsck, and even using disk utility to reinstall the iOS. I believe that during the initial update (which is the root of the problem), there was some corruption within the directories which I believe can be contributing to my problem.
I was hoping to find a way to access my purchased apps from the app store on a windows computer so that I can make a USB boot drive in order to rule out the hardware problem that I am currently speculating.
Please advise, thanks in advance!

Yes if you have the iPod and iTunes set up to sync via wifi. However, you have to do it from your one syncing computer and the iPod and computer have to be on the same network.

IMac 24" (mmid 2007?) Black boot screen, Fans run normal, HDD Spins, Optical drive Spins, no chime and can't find how to fix.

So my girlfriend boss wanted me to fix her computer. So I brought it home turned it on, and it didnt chime but it booted to the gray screen with apple logo/ slashed circle/and folder with a "?" So I made a USB Mac OS x bootable drive (FLASH) held down alt (try using a windows keyboard its fun) was able to select option and install a fresh copy. all seemed well was running really hot so I poped of the screen. HOLY MOLY! this thing is CAKED with dust, and I am not kidding it has literally piles of dust. So I ran updates, and did firmware updates. Turned it off for the night.
The next morning I went to radio shack and got Dust remove spray, opened it up made sure I was carful taking off the screen, and blew the sucker out. now its NICE and CLEAN. then i made sure I plugged everything in and turned it on. Drive spun like normal, Optical checked for a CD, and fans are also running normally. but no chime, no nothing stays as silent as normal but doesnt budge, it is like it hangs.
Some background knowledge I know next to nothing about Apple, I am Windows based but have been intreged with the new line of Mac Books. anyone help me out?

I figured it out it was the ram. I had took one from my old laptop and its was 6400, and the Mac i have calls for 5300 i went picked some up and wam it turned right on. WOOT!

Booting GRLDR. Reseting the boot drive. Is not this normal?

Hello!
"Booting GRLDR
Reseting the boot drive." appears for about 10 seconds while booting G410m-mm. Is not this normal?
I merged the two partitions (logical disks) to one.

I am up and running again. I removed my SSD and replaced it with an older drive that I had removed when I put the SSD in. The old drive could not be seen on reboot, but the SSD could be seen through a USB port. I assumed this meant my SATA controller had a problem. I decided to reinstall the SSD in the empty optical drive bay. Int he process I had to remove the 2 OS X hard drives, the one that booted in bay 2, and the one that could not be seen in bay 1. I also reinstalled those 2 drives. Bay 3 and 4 have windows drives.
Upon booting all three OS X drives could be seen. After giving them all unique names, I was able to boot back into Yosemite. I have no idea what was wrong. Was it the OS, the drive, the SATA controller? All seem to be working now.
Lets see what happens when I try to play my game again!

Drive access impossibly slow... Even though target disk!

Drive access on our MacBook Pro is suddenly impossibly slow - taking five, ten minutes to startup, and being unable to complete an install (Java update). I found no errors in disk repair and just 'ignorable' errors in permissions. Programs crashing or haltling - even Finder and Force Quit aren't coming up.
Plugged it into my white MacBook to run Drive Genius to see if the drive could be salvaged, and disk access is slow even this way. Crazy slow, like taking several minutes just to get the drive information.
Size: 499.25 GB (464.96 GiB, 499,248,103,424 bytes)
Formatted As: Mac OS Extended (Journaled)
Volume Block Count: 121,886,744
Volume Block Size: 4,096 bytes
Volume Size: 499.25 GB (464.96 GiB, 499,248,103,424 bytes)
Journal: Enabled
Used: 259.67 GB (241.83 GiB, 259,666,432,000 bytes), 52.01%
So it seems normal, just really, exceedingly, impossibly slow.
What are the possible solutions? I'm not entirely certain it's just the drive; one of the USB ports on the computer is randomly non functioning, no software indications.
-Crissa

Using the online hardware test tool (Boot using Option+D) I was able to discern that the operaitng system had decided the drive was bad without actually telling me it was bad. Eventually the drive completely failed.
While it was slow, I had backed everything up. I found a guide to replacing the HD, although I did not actually need the fancy screwdriver to put the drive back in. It was very simple!
The USB issue still comes and goes, though.

IMac won't boot, dark screen after normal grey start up screen

Quite perplexed with this problem, have tried everything I can think of.
Computer: iMac 2.16 gHz 24" mid 2006, 4 gig RAM
OS: 10.6.8
Froze and required hard shutdown. Subsequent to this, has behaved consistently:
Normal grey screen with Apple logo and spinning timer, can hear disk activity. Then the screen goes dark and nothing else happens (although the computer is still on). Have to perform hard shutdown.
Have tried:
1. Booting into single user mode (multiple times) and performed fsck, no errors noted
2. after using 'exit' command in single user mode, computer attempts to reboot but then freezes after noting 'panic'
3. Reset PRAM (no change)
4. Tried safe mode boot, progress bar on grey screen progresses, then spinning timers comes on, then same crash with dark screen
4. Disassembled computer, removed hard drive, mounted normally in external SATA enclosure. I backed up critical data, ran Disk Utility Repair, no errors noted.
5. Reinstalled HD, reassembled computer, rebooted, same issue
6. Attmepted to boot with Snow Leopard Install disc to perform a fresh Achive and Install - after prolonged grey screen with spinning timer and audible DVD drive access, same switch to dark screen and no further progress
7. Same panic message and stalled boot attempt noted when booting into single user mod
I'm stumped. My assumption is that there is a courrpt file that is causing a kernel panic during boot and I assumed that I'd be able to perform an archive and install but when this failed I'm guessing all I can do is replace the hard drive with a new one and then go through the hassle of transferring all the data over manually.
I would welcome hearing any other observations, similar experiences or other ideas. MTIA.

One update ... when I boot the computer and get the 'dark screen', I hear disc activity. So I started hitting the return key and I get the chime with each return as if I'm on the log in screen and hitting the return to log in without entering any text.
That would argue there is a problem with the screen.
However, it does not explain why the computer display works normally during single user mode and hangs (without the screen going dark) when trying to reboot from this mode.

Permissions problem with new SSD boot drive

I recently installed an OWC SSD drive as a boot drive on an iMac I've had for many years. I’m having some sort of permissioning error that I can’t figure out how to resolve.
I’ve setup the SSD as the boot drive (created user named “Boot Admin”). 10.9.3. All data and files remain on my old spinning disk
When the computer first boots, as expected, I’m presented with 2 users at the login screen (“Boot Admin”; Original User Account). If I choose my old user account, I receive the following error:
"You are unable to log in to the user account “<name of original user account>" at this time. Logging in to the account failed because an error occurred.”
If I choose the Boot Admin user I’m able to login without issue as the Boot Admin user (no access to my original apps and data). At that point, I can choose Log Out from the Apple menu and then login using my old user account. When I follow that sequence, I’m able to login with no issues. Apps are there, data is accessible etc. I can enjoy the speed of the SSD.
Although, if browse within Finder to the Boot Admin user on the hard drive, none of the folders are accessible (the little red icon is on the folders). Similarly, if I boot straight into the Boot Admin user and browse to my original User on the hard drive, none of its folders are accessible!
I am at a loss on how to troubleshoot. Ideally, I would like to login in directly to my old user account (eliminate the 2 step — login to Boot Admin, log out, login to Original User) and have full file access to things within both the Boot Admin user and my original user account.
Any guidance or tips on how to troubleshoot? thanks in advance

I appreciate the continued assistance. I'm clearly overlooking something and Google is not my friend! I've tried.
At the expense of repeating myself, I'll share my current configuration:
10.9.3
2 hard drives (new SSD with name "Boot Drive" and original spinning disk "Macintosh HD")
Startup Disk in System Preferences is "Boot Drive"
"Macintosh HD" has 3 User Folders: bootadmin, jayelevy, shared
jayelevy is my home folder - all my documents are in tact
bootadmin has the normal home folder structure
"Boot Drive" has 3 User Folders: bootadmin, jayelevy, shared
jayelevy is empty; no folders
bootadmin has the normal home folder structure (Desktop, Documents, Downloads, Movies, etc), but each is empty with the exception of Movies and Pictures. I've moved my Aperture databases to these 2 folders to take advantage of the speed of the SSD
When I restart the iMac I'm presented with 2 user choices: jayelevy and bootadmin
If I initially select jayelevy, I receive the error mentioned at the start of the thread
If I initially select bootadmin, I can login without issue, but get the standard Mac desktop (not my home).
If I then log out of bootadmin (not restart, but logout) and then choose jayelevy, the signin completes successfully and my desktop/home folder is restored to it's normal and expected condition.
I am still trying to avoid this step of login/logout/login.
I imagine I'm overlooking the obvious, but I'm in uncharted grounds for me! Here I thought the hardware swap to replace my optical drive with SSD would be the hard part. That was simple! I've stumbled on the software side!

Hard Drive clicking noises on new 60 gb iPod w/ video

My problem is whenever the iPod needs to access the hard drive for information, such as whenever I hook it up to my computer to sync or when it reads an audio or video file for playback. the clicks are pretty quiet, about half the sound level of a wall clock 'tick tock', but I am concerned. I purchased it about 3 weeks ago, and when i got in the mail, it had this issue to begin with. This never seemed to have happened on my old 4th gen 20gb, or it happend so quietly that I did not noticed. Is this clicking normal noise normal? Do you think I should get an applecare plan for the iPod just in case it goes ker-plunk? I have an Apple Store about 40 mins from where I live, do you think it would be wise for me to go and have them check this out?

Don't worry, the harddrive 'click' noise is normal. Most people on this forum will usually respond saying that it is normal, some may say it is not though. My ipod does it and I've seen this on the forum before and people say it is normal. It's just accessing all of your information.
You don't need the applecare plan for this problem but I would get it just incase anything else were to happen. Read about the plan and see what it covers. I believe it covers the battery so if you plan on using your ipod for about 2 years I'd get the plan. If you're a technology buff who plans on getting the next new ipod that comes out, I would not get it.

Boot Drive fills on it's own...?

So start of another school year...build and test images, blah, blah, blah. Everything running great. After all machines were imaged I notice server is responding slow. Log on through ARD and i'm met with a warning message that HD is almost full (4mb remaining!). Its a small boot partition so I think maybe I made it too small (though I've had no issues the past few years). Install new drive with larger partition and clone. Reboot and everything is good. Today after the weekend I come in and see that the new boot drive has filled itself as well. Right now NO ONE is using or accessing the drives as I haven't enrolled the kiddos yet. So it's happening on it's own accord. I'm sure the clone just copied whatever originally caused the problem, and it just took longer to fill the much larger drive.
Suggestions?

No cause found yet. Has happened twice so far for me....even put in new HD to give it "room". Here's an interesting artifact that someone may be able to run with:
Last time it happened I started it up in FW mode on another machine. Finder verifies that drive is full. No Logs of abnormal size, no mystery folder of GB unaccounted for...major frustration. Decide I'll boot normally and let it run dog slow so I can check console out. Guess what? It booted fine and reported back with 60GB of free space! My first thought that maybe the swap file wasn't clearing itself but surely booting into FWDM would have forced clear it. Long story short, I'm keeping an eye on the HD storage levels...been holding strong for a week now. If it happens again, maybe try just rebooting machine....

Excessive hard drive seek noise

Any ideas? Since a few days ago my (2 month old) T500 has been bugging the heck out of me (understatement) with this constant hard drive seek noise. You normally expect short bursts of it when accessing large amounts of data etc. but this has been literally non-stop, anytime the computer is on (regardless if anyone is actually doing anything on it).

Hello timosy,
it would be helpfull if you can tell us your OS and did you install anything before this did happen?
Also I would suggest to download Process Explorer from Microsoft page and tell us, which process make your hdd running that way.

Internal boot drive not mounted -- Mac does not restart

Hi everyone,
I've got a problem with my 2013 MacBookPro 13" with OS X 10.10 Yosemite.
It seems that somethings wrong with my internal boot drive. I wanted to start my Mac but the grey progress line stopped at about the half and didn't continue. I tried to boot in secured mode --> not possible. I loaded recovery mode and wanted to check and repair disk utilities but I cannot hit those buttons because my drive is not mounted and cannot be mounted. I also tried to connect my Mac via Firewire with another Mac in Target Disk Mode --> Drive could not be mounted. Finally I tried to mount my drive on a Windows and Linux computer --> not mounted :-(
Is there another possibility to mount my drive or to access my data somehow? The thing is that I do not have a backup and that is why I need to access my data and store them somewhere prior being able to do a clean reinstall of my Mac.
Thank you for your support.
Markus

Boot into the Recovery volume (boot with the Command + R keys held down), select Disk Utility and try to repair the disk and disk permissions. If you're able to reboot normally and see that works.
If not reboot into the Recovery volume and reinstall the system.
If you can't boot into the Recovery volume mamau08 may be right in that the drive has failed.

My opinion on WD Raptor as boot drive

After doing much research, I decided to buy the WD 150 ADFD and use it as a boot drive in my MacPro 2.66. In the other drive bays, I have two WD RE320's as RAID 0, and a single WD 500 for storage.
The reason I'm posting is not to specifically ask a question, but to give my honest opinion on whether a single Raptor makes for a good boot drive or not. As I did my research on the web, I found the general consensus that the Raptor was the drive to buy if you could afford it. The noise was supposed to be not that noticiable, and the speed vs lack of storage was a reasonable trade-off. It's supposed to be the premium SATA drive! As it turns out, I found that consensus to be wrong, and my trust in others opinions is going to cost me a 15% restocking fee. I bought a Raptor last week and have been trying it out over the holidays. I'm sending it back tomorrow and eating the restocking fee that Newegg charges for returns.
The reason I'm returning the drive is because, first off, the speed is not that significant when you consider the premium you are paying for it. The Raptor shaved about 3 seconds off my boot time. Big deal (sarcasm). Applications open maybe a second or two faster (big deal again), though it's hard to tell on my MacPro because it's so fast to begin with. As for general "snappiness" to the OS and general computing, I found NO discernable difference between the Raptor and the stock Seagate that shipped with the computer. Working with Final Cut Pro, I didn't notice any difference in performance and that is my primary application. The RAID 0 is probably having more positive effect on rendering than the Raptor. Then there is the noise... first let me say that the Raptor is quiet when it's at idle. I have no issue with that. The problem for me is that when the head starts seeking, the sound is jarring. Like microwave popcorn? Tadadadadadada...tick....tick....tick....tadadadadada.
What makes the seek noise so bad is that the computer is normally so quiet by comparison. So, if I'm sitting in my office and it's really quiet, all I hear is the faint sound of my X1900 fan. Then the Raptor kicks in and it's like finger nails going across a chalk board. Okay... maybe that an exaggeration, but it really is distracting! I also really hate when the Raptor just does a random loud click when your surfing the web or not doing anything disk intensive. Like, as I'm writing this post... click.......(silence)................... click, click...............(silence)... you get the idea. None of my other drives do that.
I think the Raptor is probably the way to go if your using them in a Raid configuration AND in an area with fairly loud ambient sound, or if you have a tendency to always have music on. However, if you are fairly sensitive to jarring noise and don't need to worry about shaving a few seconds off boot times, then I suggest to go with something besides the single Raptor as boot. Raptors in RAID is another issue entirely and I'm not knocking that. What I am knocking is when I read where someone posts that the noise in their Raptors in RAID are barely noticable. I call BS on that so beware.
I'm sending my Raptor back soon as I get an RMA and going back to the stock Seagate until I figure out what else to use. Maybe the WD SE 320 Caviar or the Maxline Pro? Something around 320GB for OS and applications only and a Windows partition.
Any suggestions?
Thanks for reading. Your comments are appreciated!
Al

To be honest, I haven't run extensive scientific
tests but the ones I did perform didn't show much of
an advantage using a single Raptor as the
OS/application boot drive. Last night I booted off
the Raptor and then loaded a Final Cut project and
rendered out the timeline. The scratch disk was set
to the RAID and the media was coming off a storage
drive. It took 4 minutes 49 seconds to render the
timeline. Next, I booted off the stock Seagate 160
(7200.09) and ran the same render. The OS was an
exact same version that I'm running on the Raptor (I
had cloned the Seagate from the Raptor using
SuperDuper!). Anyway, I ran the render on the same
file and it took exactly the same amount of time. 4
minutes 49 seconds.
Again, am I missing something here?
You are not missing anything.
Using a "fast disk" as the system drive will improve some things, and if you are used to an older, slower disk drive then you'll probably notice a bigger difference. A Raptor in a macpro for OS use is only going to help marginally, in the way you have noted. Better, but not that much.
I'm not sure about your expectation of seeing FCP perform better in your test though. I wouldn't expect there to be any improvement there. Rendering speed tends to be limited by processing rather than disk speed for a start. Where a fast drive helps is when applications need fast reads and writes. Writing a 100GB self-contained movie from the FCP timeline to some external storage wont be speeded up no matter what system drive you have (unless the original footage is stored on the OS disk of course!). The speed will be dictated by the drive your writing to and the drive you are reading from. Unless you have set your scratch disk as your boot drive or footage is stored there or you're writing to it then the boot drive will have no effect.
Like everything in computer land, whether you need that extra power, speed, size etc always erm... "depends". having just 5% extra kick might be the difference between a realtime preview or a render for eg.
I agree with a "vibe" I am picking up from you though: that all those reviews and user comments on the web can be very misleading. If you've spent $50 more on something then its not easy to admit (even to yourself) that it wasn't ~really~ worth it. Once you see the quoted benchmarks for yourself and the 2sec reduction at boot most folks will feel the purchase was worth it. Will it make you work better? Not really. I went from a G3 B/W mac to a MacPro but the music I make is no more jolly than it was before
If you ~really~ want to see big improvements to any standard drive you have to look at RAID and more specialist solutions like scsi and fibre channel - but even these wont make your processor work any quicker!

Start Up disk problem following kernel panic-mounts but not as a boot drive

I have a problem that I can't solve.
Dual processor G4 with 3 hard drive, all of which are bootable drives with 10.4.7 installed:
A- my primary boot drive - internal SCSI drive (Adaptec PowerDomain 2930U PCI card);
B - internal hard drive that came with the G4; and
C - external Firewire hard drive
Recently, I booted into my B drive and it locked up after it went into sleep mode. On reboot, I experienced a number of kernel panic messages, prompting me to restart my computer.
PROBLEM: Since that time, I have not been able to get my A drive to once again be the Startup Disk.
Diagnostic steps that I have performed:
i. I have run and re-run Disk Warrior from a bootable CD and the A drive as well as the other 2 hard drives mount and are "repaired" by DiskWarrior.
ii. TechTools Pro shows no hardware problems and whatever glitches it has found were repaired.
iii. Disk Utilities consistently returns "Volume passed verification."
iv. Zapped the PRAM
The A drive does mount and is accessible whenever either the B drive or the C drive is the bootable drive.
System Preferences/Startup Disk lists the A drive as a candidate whenever either the B drive or the C drive is the bootable drive. However, when the A drive is selected in System Preferences, on reboot, it doesn't become the boot drive.
I have tried to restart and hold the "C" key down so that I might possibly be able to select the boot drive from A, B or C. But the C key method doesn't produce the intended result, only reverting back to the boot drive in power prior to the reboot. That occurs whether the boot drive is B or C.
At that stage, rightfully or wrongfully, since the problem persisted whether the B or C drives were the startup disk I concluded that the problem could be hardware related and not software related.
On one of the reboots following the kernel panics, a Crash Report was produced - the verbiage
which is code related and so far above my knowledge and experience that it is incomprehensible to me. I can post it separately if helpful but it won't fit in this email message due to restrictions on length of messages.
I haven't had a kernel panic following any of the last 50+ restarts that have accompanied my attempted diagnostics.
Finally, I ran the Apple Hardware Test, version 1.2.6, that came with my G4. First, I removed all peripherals except the monitor, keyboard and mouse (plugged into the keyboard), the Adaptec SCSI card, and a 3rd party FW/USB2 PCI card (OrangeLink+). I ran the Extended Test and an error code was generated during the logic board test: Error Code fire/5/2
That gave me some hope. I next removed the 3rd party FW/USB2 PCI card (OrangeLink+) and re-ran the Apple Hardware Test and no error were reported. Both the logic board and memory passed. I ran the extended test twice, each time no error.
Ah, did that solve my problem? I rebooted and I still cannot get my A drive to be the Startup Disk.
Next, I ran the Rember software (a GUI app for Memtest) and the RAM checked out as fine.
At this stage I don't have a clue. The white towel is about to be waved.
If the problem is the Adaptec SCSI card, I don't know how to test it since it obviously has to be installed to enable drive A to mount.
Does anyone have any suggestions?

I am the original poster on this thread.
Turns out that the culprit behind all my boot problems was the battery on my 5 year old Quicksilver G4. Replaced the battery and all is back to normal.
FWIW, for any Quicksilver owners with SCSI cards, be aware that you can create boot problems for your SCSI drive by zapping your PRAM. As part of my diagnostics I did zap the PRAM but that turned out not to be a problem.
Adaptec's site does include a workaround should you have problems after zapping the PRAM. This specifically covers the PowerDomain 29160 SCSI card/2930U card, which I have.

I have one 120GB SSD and one 1TB SSHD, how do do I make one of them my boot drive and the other my data drive?

I'm currently upgrading my mid-2010 Macbook Pro 13", I've purchased some new RAM and also a 120GB SSD and a 1TB SSHD (Hybrid SSD and HD) with the intention of using an OWC data doubler to get rid of my dvd drive and place the SSD drive there instead. So after I've placed everything into the Mac, how do I make the SSD my boot drive with the OS on it and everything, and the SSHD where all my data (music, photos etc) are stored?

Youll need to CLONE your internal HD to your target (temporarily) external drive.
1. grab carbon copy cloner or (my fave) superDuper CLONE app.
2. attach target clone drive via USB in an enclosure or HD dock. Firstly format the target (external new) HD in disk utility in “Mac OS extended journaled”
3. clone internal HD to target HD (external) [takes about 40 mins depending on size]
4. Boot ONCE from external (go to sys. preference to boot from external) to TEST the new Clone
5. open bottom (see videos on ifixit or youtube on same) and remove old, install new.

Done
(FIRST TIME after installing, boot will be SLOW,...normal and ignore that).
Clone APPS
Superduper does not clone the recovery partition, but that is NOT necessary if you keep the original HD as a “backup clone”. Most don’t bother with the recovery partition in a clone, however that is your prerogative.
