Safe to turn off hard disk sleep?

i have a powermac g4 with mirror drive doors. i've been having occasional trouble waking from sleep. i turned off sleep mode for the computer, and unchecked "put the hard disk to sleep when possible". is this safe for my computer, or will it harm the hard disk?

If I had a nickel for every "sleep" related question I wouldn't have to work for a living.
Your hard drives are, as David says, fully capable of running all the time. Some swear that it is better for the drives. My belief is that this comes from the experience of older hard drives which were best left on all the time. Newer drives are designed to power down as required by the EnergyStar mandates. So they can run or sleep and it really shouldn't matter.
What does matter is the not waking from sleep. If by that you mean you had to use the power button to shut down completely and then restart your computer acutally crashed. If/when this happens you should do one of the following upon or before attempting to restart
1) Boot single user and run fsck
2) Boot from the install disk and run Disk Utility from the cd/dvd
3) Hold down the shift key for a Safe Boot which also runs fsck before booting fully
The chances are that the directory was ok when the computer entered sleep and the journal of the hard drived was up to date. But if not then repeated hard reboots will accumulate directory errors which will mess things up.

[BUG?] "Turn off Hard Disk after - NEVER " Does not work ?

Hi,
I was using last 2 builds of Windows 10 Tech preview x64, and found this weird behaviour. I've updated to this new 9926 build, clean installation, and it happened again:
I have Windows installed on my SSD, and I have several other Hard Disks (internal ones) connected. Whenever I try to search files inside any of those HDDs, they have to turn themselves on, which causes a 2-3 sec lag, and then allow me to continue. When I'm
done working inside them, and some minutes pass, they turn themselves back off again.
I do know theres an power management option called "Turn Hard Disk off after..." and I have chosen it to be at NEVER. But it's not working.
Has anyone had same problem? Is it a known bug or something? Any way to fix this?
Thank you for your time, and forgive my level of english.

Chris,
These steps from a recent post by AndyO should help:

+"Your problem may be that the new hard drive in your mini is not yet prepared correctly for the MacOS installer to recognise it.+
+"Once you are booted to the installer disk, instead of attempting an install, open Disk Utility in the Utilities menu. If the drive doesn't show up on the left, it is not correctly installed, and you will need to open the system up again and check that it is connected correctly. If it shows up in Disk Utility, you need to partition and format it correctly. To do that, click on the drive in Disk Utility to select it, then click the Partition tab. Under 'Volume Scheme, select a single volume, then click the Options button to bring up the partitioning choices. For a G4 mini, you want to select Apple Partition Map. Click OK to confirm and it will partition the drive and should also format it as Mac OS Extended (Journaled). Once that is done, you should then be able to run the MacOS installer which will then recognise the drive and allow the install.+

How to turn off hard disk identification in LR 3.3?

Hi!
I have a problem with LR 3.3 on my Windows XP. I have a lot of harddisk (1TB, 2TB SATA2, made by Samsung) in my XP system with my RAW photos, all encrypted by Truecrypt. When I need to import my existings photos from that secured harddisk (Truecrypt is the best tool i have tested), LR 3.3 is blocking option Move and Add in Import dialog.
I must duplicate my photos by Copy options only - like from memory card.
LR 3.3 is thinking, that my encrypted harddisks are my memory cards, and is disable Add and Move option.
How to turn that bad identyfication off?
And in the end, every time when I want to import photos - LR 3.3 is searching all my TB harddisks (more then 30 minutes) to create and show my thumbs in folders - and I can not stop this searching. How to turn it off too?
Regards

Remisteness,
There are a few things to mention regarding your problem:
1) Scanning all of the Drive(s) after Starting Import
Right after the import dialog opens, try to click onto an internal drive as soon as possible and uncheck "Include Subfolders". This should prevent the scanning of the drive(s).
2) What is presented to the O/S for an Encrypted Device
Obviously, your encryption software presents the "virtual" drives as removable devices to the operating system, which leads LR to treat them as "Cards".
I have a similar software in use to access encrypted data in "Container Files" (SafeGuard PrivateDisk). In SafeGuard PrivateDisk, I can configure how a "virtual" drive is presented to the Operating System, either as a removable device or as a simulated harddisk. If I choose "Simulate Harddisk", the "virtual" drive is represented like a harddisk in my WinXP and LR does not show it as a removable device, hence without the restriction imposed on "Cards" during import.
3) Restrictions imposed by LR while Importing from "Cards"
LR prevents users from moving photos when directly accessing a memory card, because if a file would get corrupted during import no valid copy of the image would exist anywhere anymore. Also, adding photos residing on a real memory card does not make sense either, as too many users would be looking for their original images after disconnecting the (and possibly reformatting) the memory card.
There has been a lengthy discussion in this forum lately on whether it makes sense or not that LR tries to protect users from their own wrong doing. I guess one can see it either way, and the limitations chosen by Adobe kind of protect Adobe from too many questions/accusations.
4) Workaround for LR 3.3
To be able to add or move from a removable device in LR 3.3, you can do the following:
Create yourself one or two Import Presets, with Add or Move as the action to be performed. You have to create these presets while doing a test-import from a interal or external HDD, and save them from there.
When accessing your removable device, access the drive by clicking onto the drive letter in the drive list below "Files", and not by clicking onto the removable device under "Devices"
Choose one of the Import Presets built in step 1
This will use Move or Add as the action to be performed (note that no action at all will be highlighted), even though you're importing from a "Card".
As this behaviour is a hidden/undocumented feature (or even bug?), we do not know whether this possibility will still be existing in future releases of LR, but for right now it seems to be a workaround.

I just added two external firewire drives and they keep going to sleep. I did not have this problem when USB. I have turned off "put disks to sleep" in power preference.

I just added two external firewire drives and they keep going to sleep. I did not have this problem when using USB external drives. I have turned off "put disks to sleep" in power preference.

It is not clear if these are the same drives, just connected
differently, or different drives?
One thing that may be happening is that the drives firmware
itself is putting it to sleep when inactive. Many drives on
the market have ths feature and it is turned on by default
and require a drive utility from the manufacturer to disable it.

When I click sleep, Imac turns off not just sleep

When I click sleep, Imac turns off not just sleep. Any fix?

Hi Hank,
Some things to try...
Have you done a PRAM reset, CMD+Option+p+r...
http://support.apple.com/kb/ht1379
In fact, do 3 in a row, takes a bit of time.
Intel-based Macs: Resetting the System Management Controller (SMC)...
http://support.apple.com/kb/HT3964
(SMC reset= Shut down, disconnect power cord for 10 seconds, reconnect power cord, wait 5 more seconds, turn computer back on)
but it is slightly different: (PMU REST = Shut computer down, disconnect power cord for 10+ seconds, reconnect power cord WHILE SIMULTANEOOUSLY PRESSING POWER BUTTON, let off power button for a few seconds, then press power button again to restart the mac mini.)
Can also be caused by USB or Firewire devices.

IMac turns off instead of sleeping

This only recently started occurring, and I cannot correlate it with anything that I might have done.
When I tell my iMac G5 to go to sleep - be it via shortcut, menu, power button, anything - it turns off instead of sleeping. It does not shut down properly, but simply turns off suddenly and completely. Upon rebooting, everything seems to be functioning well.
Did all the usual reboot, fix permissions, and so forth, to no avail. Apple hardware test reports no problems, although it took over an hour to run an extended test.
Any help would be appreciated.

You haven't done anything, it's a power supply problem or a capacitor problem and you should take it in and have it seen to before it gets any worse. Make sure you have a backup of all your data before you take it in. If it's not an iSight, you can open the back and check the caps to see if they are swollen or leaking. While you're about it, vacuum the fans and the vent slots to see if excessive dust buildup is the problem.

Why in the world did update 1.4 start turning off WiFi in sleep mode again?

This time, we werent even given a choice. It just turns off by design. Thats not cool! I really solely on WiFi at home because my EV connection at home is close to nothing. You guys can ask Sprint to put a tower in New City, NY.

I agree that some time ago you stayed connected.
I have the same problem now: twitter messages don't come in anymore when phone is in sleep mode.
Before they always came in directly when sent.
Apple should give us more options so we choose for ourselfves what we want.
It must be very hard to create an option: wifi off when in sleep mode yes/no ?
Also making a real copy of a picture that you have taken would be nice.
So when you delete the original, the copy keeps existing !

Hard drive disconnects itself improperly-Hard disk sleep?

Hello,
I have recently bought a 2011 Macbook Pro and I am facing a problem with an external Verbatim LCD hard drive.
It seems like when the drive is inactive for 10 minutes or so, it gets disconnected improperly, I get an error message and the drive disappears from the system until I unplug it and plug it back in.
Also I have noticed that when the disk is in use , it does not disconnect. I tried leaving playing a movie to see what will happen and everything was ok. When I stopped the movie and left the Macbook Pro it disconnected itself after a while.
I know this may be bacause of the option in the Power Saver "Put hard disks to sleep if possible".
So, I have decided to untick this option and up to now everything seems fine again.
I just wonder, should I leave this option on or off? And if this option is there, why does it cause such a serious problem like disconnecting a hard drive?
This certainly should not be happening!
I would appreciate any information on that.
Thank you in advance!

Anyone?

Hard Disk Sleep Issue

Does anyone else notice their Hard Disks trying to sleep even though the "Put the hard disk(s) to sleep when possible" box is unchecked in the Energy Saver preference pane? I keep hearing drives inside my Mac Pro spooling down, then normally spooling up again 30 seconds later. I've tried restoring the prefs to default and an SMC reset with no luck. Thanks..

Hi Mate ! I am experiencing the same problem with my MacPro - did search a lot of discussions - but didn´t get any helpful answer. I switched off all sleep/energy saver modes. Did all system resets, even all onyx scripts - nothing helped. From time to time - specially when working with the Mac Pro Apps - the second internal diskdrive falls to sleep and needs about 20 to 30 sec. to reactivate. I can switch between programs at that time, but all I see is the rainbow wheel. Does anyone know a workaround for that ? It would be very much appreciated

T42p vista fn + f3 and fn + f4 functions (turn off screen and sleep) not working correctly

Hi -- I recently installed windows vista on my T42p. It works fine except that the fn+f3 and fn+f4 functions do not work as expected. Before installing the hotkeys driver, the fn+f4 function worked correctly while f3 did not (going to sleep worked, turning the monitor off did not). I then installed the recommended hotkeys driver. Now fn+f4 makes the monitor turn off while f3 does nothing ... fn+f4 is supposed to put the laptop to sleep. On top of this, if i select "sleep" from the start menu, the computer turns the monitor off instead of going to sleep.
Presumably, the sleep button could still be telling the computer to go to sleep, but the actual operation of going to sleep is now broken? Just a guess. Anyways -- anyone know how to resolve this so that fn+f3 turns my monitor off and fn+f4 puts my computer to sleep?

I've too this problem, but more, my sound mute wasn't worked (for deblock, but it can block it few second before...) 5 days in 5-6 instalation of three version of winxp: winxp ru x64 sp2, winxp es/ru sp3 x32.
eventually I've found and ran "TPOSDSVC.exe" in instalation directory and it give an opportunity deblocking the sound volume!!!!!!!!!!!! and I don't need more functions
volume levels and brightness adjustment worked well without OSD (before I ran TPOSDSVC.exe) and with OSD.
and now I don't know worked this bustered sound driver in winxp x64.

MacBook Pro Retina and Hard Disk Sleep

I have noticed in the Energy Saver in the System Preferences section, that their is a Put Hard Disk to sleep when possible, but I know that my laptop is an SSD and not a hard drive. Is this something I should uncheck or leave checked?
Thanks!

You can leave it as it is now. That option also applies to the SSD, although you see hard disks

IPhone turns off when in sleep mode

Hi my phone turns off after being in sleep/lock mode after a few minutes. to turn back on i have to hold the home and power buttons for a few seconds.
When the phone is charging it does NOT turn of in sleep mode.
My Info: iphone 2g..Fw 2.1
I read a few post on here and other forum sites that say it may be a hardware issue or battery issue....If your having this problem please reply to this post to let it be known if there is a hardware problem or just isolated incidents thanks

Hey SurgeCentral,
Are you using any 3rd-party accessories with the iPhone?
Try syncing and backing up the data on the iPhone, then restore it and set it up as a new phone.

How to turn off hard drive standby?

Hi,

Wow, that was fast. Thanks a lot!

Wifi automatically turned off when phone sleeps in iOS 5.1.1?

Before, I used iOS 5.0.1 and wifi would keep turned on when the phone sleeps if I turn off data. This way I could always receive instant notifications. But then I sold the verizon phone and bought a used FU one, installed with iOS 5.1.1. Now wifi is automatically turned off when phone the sleeps, even when data is off. Is this how it works? Because I want to use wifi, even when the phone is off. Thanks.

I have had and iphone 4 for the last couple of years with all the different IOS upgrades and never experienced such a thing!? I do not have a cell data plan (I even have it switched of in settings) so I rely on wifi and, even when the phone was in standby, the wifi was constantly on! and I received e-mails and skype calls as they arrived, So wifi was certainly ON!
However, since the last upgrade to IOS 6.0 the wifi is indeed being turned off when the phone goes to sleep mode, which is very annoying!
Any fix/workaround?
Thanks

External Hard Disks Sleep after 10.8.5 update

After installing the latest Apple update to Mtn Lion, my external disks sleep and cannot be awakened via remote access. Nothing changed except the update.
It happened at work as well as on my home network.

I am on a Mac Pro 2.8 (3.1) 2008 model. 12 Gb ram and a radeon 5870. This supplemental update has been pretty horrible. I have had the following issues: messed up sleep, random wake ups, and one hard crash. I have also had the long sleep delay where the fans crank up and it takes forever to sleep...only a restart cures this, which is pretty useless. The mach file showing but that was fixed with a terminal command. Lost video chat icon on iMessage for a while but that has now mysteriously returned. The last annoying bug I have suffered with is what seems like horribly reduced audio quality out of the Apple LED 24 inch cinema display speakers. It sounds like 22kz mono both input and output.
I would rate this update a full on zero out of ten, for creating problems that never existed in 10.8.5.
