OS X V10.7 Lion :: Manually Put An External Hard Disk To Sleep?
Jun 25, 2012
Is it possible to manually put an external hard disk to sleep? Right now, I've already got "Put the hard disks to sleep when possible" checkmarked in the Energy Saver preference pane, and so they should sleep after 10 minutes of inactivity, but I'm wondering if it's also possible to do this manually whenever I want.
I just bought an external hard drive and it's already spinning constantly, compared to my current external which is completely quiet, so I'm wondering if I can put it to sleep when I need to to stop it from spinning all the time.

I have a 2TB Western Digital My Book Studio FW800 external that has 5 partitions, connected to my 2011 iMac. I had help doing the partitions and don't really remember the reasoning, but one is just for my SuperDuper! backup, one is Miscellaneous, one for movie clips off my camcorder, one for misc scanned photo's and one for my genealogy research. I back up using Time Machine to a Time Capsule and also to this WD hard drive with SuperDuper!
Recently I'm getting a pop up message that "Mac OS X can't repair the disk "Genealogy"'. And it needs to be reformatted. It's become a read only disk. When I look in Disk Utility it shows all the partitions as "Mac OS Extended (Journaled)" EXCEPT for the one in question. I also noticed that there are a lot of files with "date created" being the same date in 1969! These files may be letters I've written or photo's I added to that partition within the last few years.
I think I have to completely reformat the entire external hard drive to repair this, but I want to make sure. Because it's going to be a major hassle backing it all up to another external (having to get one first) and then figuring out how to make the files that have turned "read only" in that one partition, back to their original state! Does this sound right, that I have to reformat the entire external hard drive? And how do I get the read-only files back to their original state.

How do I reformat a USB external drive with two partitions one of which is corrupted.
Disk Utility will not work because the faulty partition prevents unmounting of the disk.

i have this strange issue that occured just out of nowhere without me (knowingly) having contributed anything to it.yesterday i launched my iMac and my external firewire drive wasn't showing up in neither the finder nor on the desktop. i instantly thought about a hard drive crash, but soon tried other things to evaluate (or not) my guess.
for instance, i unplugged the drive waited a few minutes before i plugged it in again. since this iomega drive is also equipped with a regular usb port i also switched cables and tried connecting it via the iMac usb sockets as well as via an usb hub without any luck. the drive still won't show up. so i launched the Disk Utility, to see if the drive needs some checking/repairing, but to my surprise it wasn't showing in Disk Utility either.
thus far i only considered this to be an issue with only this particular external drive, but when i eventually switched on a 2nd external drive (this time an usb drive i use for Time Machine) that drive also refused to show up in either the Finder or the Disk Utility app.
curious as i was, i then fired up a 3rd and 4th external drive and now had all 4 drives running at the same time. none of which were showing up, just as if they weren't even connected with the iMac.
this strikes me as more than odd. i've heard about hard drive failures and crashes. they just occur over time. maybe and under some very strange coincidences it is possible that two external hard drives quit their jobs at the very same time, but seriously .... 4 of them?? i hardly think so.
well, maybe it's the iMac's usb/firewire controller that's causing the trouble, i thought. but then again, my other connected devices (iPhone, iPad, Printer, Scanner, eyeTV) are functioning and get detected just fine as far as i can tell.
i have no idea what's going on. i dismiss the idea of 4 external drives having crashed all at the same time just as much as i don't think that the iMac's usb/firewire controller has got any issues. re-formatting any of the 4 drives is out of the question and even if i'd consider such desperate measures, the Disk Utility wouldn't let me re-format anything anyhow, because the drives aren't listed there. i wish i could just use my Time Machine to resolve the issue but, as i mentioned earlier, i can't access the Time Machine because it also won't show up.

Recently I purchased an external hard disk, to put all of my pictures of my baby due to space limitations on my internal laptop drive. Since my Canon camera 10 megapixel pictures take up a ton of space this was occurring at an alarming rate. My intention was also to back up to DVD but never got to it. This is both a comment and a question.
Now said baby, is getting really good at pulling cords etc. He managed to do this on the external drive firewire cable. As far as i know the drive was not in the process of actually writing. However, after a few minutes and trying to re-plug the drive the OS crashed with a Grey Screen of Death hardware error that tells you that you need to push the power button..
This apparently corrupted the drive's directory. Upon reboot the drive would not mount. Since there were time machine backups on the drive too Diskwarrior was not able to reconstruct the drive in the built in memory available on the computer. Time machine stores millions of files and Diskwarrior apparently wants to keep it all in memory at once. Since my computer has 2GB you would hope that would be enough but apparently not. So that failed. Other utilities seemed to be able to find the files but not restore the directory. I also took it to the apple store they were not able to recover it.
I have to say this is extremely distressing, and hard to believe that a simple accident like this could cost the loss of thousands of pictures. I did send it to a rescue company but that was expensive but I think apple needs to do something about this situation.
On Windows there is a way to disable the write cache for external drives. This is not available for Mac OS X. This would prevent this rather common occurrence of a plug accidentally becoming disengaged when the drive is not in the process of writing. This reduces the odds but I still think apple, in order to become clearly superior, needs a better solution.
I know Apple has experimented with ZFS would this not eliminate this possibility of this kind of disaster? Is this in Snow Leopard desktop? I know they are thinking this is a business customer focused technology but clearly if it can eliminate this kind of thing then I think it is extremely useful to their non server customers. Perhaps there are other ways of dealing with this issue but ZFS is designed to deal with these issues. HFS+ is extremely fragile to disk corruption.
I know my situation is not that uncommon and this is not the first time this has happened to me with an external drive. You would think I had learned. I hate to think of how many other people have had the same thing happen to them.

I've download a Seagate Diagnostics programme to check whether my external Seagate FreeAgent Desk is working properly or not. However, when I run the programme, it indicates that cannot find the disk.

I have a Seagate 1 TB Backup Plus Drive which was working perfectly fine until I plugged it into a USB hub. It detected it while in the hub and I was able to get files off of it, but when I ejected it from the hub and put it back into the USB slot on the computer it was not detected by finder. It shows up in the disk utility and I clicked verify and repair and it says:
Verify and Repair volume “Seagate Backup Plus Drive”
Checking file system
Volume repair complete.
Updating boot support partitions for the volume as required.
Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
Is there any way to get this to work properly again? Or if not is there a way for me to recover my files on the external hard drive?
I have a Macbook PRO late 2011 running OS X Mavericks.

This is a phenomenon that I have experienced on a Blue & White G3 and a Gigabit G4, and in OS 9 and OS X: Whenever the hard disk spins down, the mac goes really slow even after it spins back up. I have to set the Energy Saver settings to keep the HD and computer from going to sleep (same result when computer goes to sleep). The problem is only fixed after I restart the machine. Same result with different hard drives as far as I can tell. Does anybody else have any experience with this or any additional explanation?

I have an external 500GB Freecom USB HDD with two Data partitions on it (FAT32 and NTFS). With a Windows tool, I made the two partitions smaller in order to free up some space (ca. 200GB) for an additional Mac OS Extended (Journaled) partition. This partition I wanted to create with the Mac OSX 10.6.4 Disk Utility. When I pluged in my USB HDD in my new iMac it mounted the two partitions, NTFS and EXT32 and the Disk Utility tool also showed the free (unpartitioned, almost 200GB) space on the HDD. Then, I chose to create a new Mac OS Extended (Journaled) partition and let the tool do it. ...which I probably shouldn't have done. Disk utility stopped and showed an error message saying that it cannot read the partitions anymore and that it needs to be closed. No partitions can be mounted anymore since then on this HDD. Here is the logfile entry of Disk Utility (unfortunately, it's in German):............

I can put my iBook G4 to sleep manually, but it will not sleep on its own. Why is that? I'm running 10.4.8 and I have the power settings in preferences set for "Better Energy Savings".

As I've read in many threads there's no way to turn off the blue light, even when my imac is off or sleep, and even thou the hdd is (or might) be asleep, the light always stays on... over all this is not a huge deal, but since the imac is in my room sometimes the light it's a little annoying. I was wondering if anyone here has an external hard drive that goes to sleep and even the lights turn off completely..
Specially if it's a famous brand.. like WD or anything along those lines.. since I'm looking to upgrade my external HDD i figured it's a good to know.. otherwise i'm going to just upgrade to the 1tb Lacie.. I'm considering the 1tb "My Book" because even thou I read that the 500gb had a lot of issues apparently the 1tb one is a lot better.. has anyone has had this drive? Any issues?

The last couple of times I have woken my MBP up a box has popped up with a big red sign in the middle saying my external hard drive was removed unexpectedly and could have caused loss of data. I know this is not healthy and I would like to stop it doing this as soon as possible. It is connected via firewire 800 and is a western digital 250 gig my book pro if that makes any difference. I close the lid of my laptop with it still on and connected and everything is supposed to sleep. It used to work fine, I would open the lid and everything would wake up and I could do what I was doing before with no error messages and the hard drive would still be mounted on the desktop.

I'm on an early 2008 mac pro - used to be on a Powerbook G4. I have a 300 GB LaCie d2 Extreme external HD connected via firewire 800. Both are in 10.5.2. While on my powerbook, the drive behaved normally - fell asleep after no use, then awakened when I needed to access something. On my new mac pro, the drive behaves strangely. I only use it for backup, so it's only accessed once a day. The rest of the time I do not use it. When it's not in use, the drive sporadically wakes and sleeps. I've tried to pinpoint the cause to no avail.
I've tried all the usual suspects: browsing the forums, checking the "hard disk sleep" preference in energy saver, switching the firewire 800 cable with usb and firewire 400, watching activity monitor to see if there's a program accessing the drive (haven't found anything, but that doesn't mean it's not there). None of it works.

I'm running out of space on my Mac Mini's disk because of all my iTunes video files. I am thinking about buying an enclosure for my spare 1 TB hard drive, and using it as the location of my iTunes library, but I wondered how it works with the Mac Mini's energy-savings mode. My Mini is set to sleep after 15 minutes of inactivity, then wake when iTunes content is requested by my Apple TV or Airport Express. I like it, because it's very energy efficient that way! My question is, will the disks also sleep along with my computer, and will they wake properly when the computer wakes?

Is it possible to have an external HDD connected to an iMac or Mac Mini on a regular basis? I have a Power Mac G4, and it's always had issues with going into sleep mode when there is any external storage connected via the USB 2.0 ports (and I've put in replacement ports to try and remedy this, to no avail). The main problem is that once the system wakes up, it thinks you've improperly removed the device. Apple told me, way back, that this was normal and to just eject all external storage before going into sleep mode. Which is a pain, but looking at a new desktop Mac I would like to just get the tiny, base HDD and use a beefy external for all my media - unless this is still an acceptable norm with new macs.

I am using an early 2011 Mac Mini running OS 10.6.7, which I have had for a little over a year. A new problem cropped up in the past week. When I put it to sleep manually it takes 2 minutes or more before it actually goes to sleep. I have "wake for network access turned off." The computer goes to sleep automatically at the time set in energy saver without a problem. The manual sleep delay happens whether or not I have applications running or not.

I've bought three over the last two years, and only one of them has lasted longer than 18 months. I think one of them may have been damaged in a fifteen hour flight, but it still works (albeit too slow to the point that it's unusuable.) My .5 TB monster just died last week, which had almost all of my video files from the last year, totaling 300 GB in data loss. What can I do to avoid such situations? Should I maybe get a 1 TB disk for everyday use to replace my .5 TB disk, then a 2.5 TB disk (or bigger) just for backups? What sort of backup software should I use? (not Time Machine, I'm not interested in backing up my entire computer several times, just my FCP files.) How long do external hard disks last for you?

My intention is to partition an external HD in half allowing it to serve as a backup for a pc running windows xp, and the other half as a backup for a mac(10.5. I am using a Seagate external HD(new) that was initially partitioned on a windows xp computer.
The 1st half of the 1TB HD was formatted in NTFS format, and the second half was erased and (I thought) reformatted in HFS plus but when I attempt to use CCC(Carbon Copy) to copy the mac 1/2 of the hard drive, I get this message:
"You may have difficulty booting from this target volume, the underlying disk is not formatted with a partitioning scheme that Apple recommends for Intel Macs."
I have read the recommendations that the external HD need to be partitioned with APM or GPT, but I cannot seem to get to that option now for the mac side of the external HD.
In the Disk Utility, the external HD shows both sections of the partitioned drive(the xp section and the leopard). I do not want to reformat the entire drive(both sections) if at all possible.
I just want the Mac side of the ext drive to be properly prepared for CCC, and the windows side to remain as is.

I want to get an external hard drive for my Airport Extreme, in the range 1tb (maybe 1.5tb but likely 1tb). Google reveals some people have had problems with particular drives so I thought I would ask which drives work well so I can just avoid any problems in the first place?

My external hard drive has been corrupted and the error message is telling me to reformat it. However, through all the research I have done to find out how, everything I've found has told me to use Disk Utility to just erase everything on the disk to do this. When I try to do this, it tells me that I can't erase anything because the disk cannot be unnmounted. What should I do?

I had a WD external hard disk which I was using on my pc but not any more since I'm not a PC user any more. However, I'm a mac user now but when I connected my WD external hard disk I found out that I have lost everything on it. I thought may be because of my mac so I connected on my PC again and i have not seen any file which means I lost everything. Give me any software on mac that will get everything that I have lost.

My Mac Pro [with 4 internal disks, 2 External Disks (Sata Raid 0), and several external FireWire disks and a Voyager disk station] has a little problem with letting externals go Since a few weeks I have a problem with unmounting my externals. After unmount, the unmounted disk will mount again immediately.No time to disconnect cables and/or power. Hinders disk management, backup, and simple disconnecting disks. It only happens with disks (FireWire 400/800/ SATA and USB alike). USB sticks work fine.

I recently acquired a MAC book Pro and this being my first APPLE product - I am still learning lots abt this notebook. My question pertains to using an external hard disk in the MAC book Pro. I have a transcend external hard drive that works on the mac book pro - without my having formatted it etc. It also works on a windows system. ( I have as yet only used it to access documents that were previosly stored in the external hard disk) Can I continue using the hard disk as -is or would I still need to format the disk to make it MAC book pro friendl
