Have to wait for Time Machine disk before opening or saving
I can't tell you how irritating it is, when it click open or save (any program) , to hear my Time Machine hard disk begin to spool up. As soon as hear that sound, I know that means I have to sit and wait for the Time Machine disk to initialize and get all set before I can save my work. This is majorly ticking me off.
This problem is present on any document i go to save/open.
Why is the OS trying access the Time Machine disk when I try to open or save anywhay??? There's no reason for that! No one is ever opening up and saving to Time Machine while doing normal workflow! The only thing the Time Machine hard drive should be responsible for is backing up!
I swear, I'm thinking about disconnecting my Time Machine disk while I'm working and just reconnect it when I'm away from the computer...it's getting that bad. I shouldn't have to do that. That's ridiculous.
Any ideas?
Thank you
Why is the OS trying access the Time Machine disk when I try to open or save anywhay???
The system will wake ALL hard disks when the save dialog is opened TM is not excepted from this. There is nothing very special a TM volume other than its icon.
There's no reason for that! No one is ever opening up and saving to Time Machine while doing normal workflow!
There are many users who use a TM drive for data other than TM backups.
What make and model is your drive? Some drives have power management controllers which have to be set with disk management software. If you have one of these drives you may need to turn off the hardware power management with this software. The problem here is that some manufactures only provide this software for Windows. Seagate is one such manufacturer

My backup hard drive does not have enough space for time machine to perform a back up even after erasing entire contents of bu hard drive. The hard drive has been in service for almost two years performing this function with no sign of failure. How do I adjust time machine perameters?
The only way to limit the size of the backup is to exclude data from the backup, which you can do in Time Machine preferences.
If you use multiple browsers, have you tried clearing your browser caches? However, that's just a stop gap if it works. You either need to limit what you backup or get another drive. -
Use a DMG for Time Machine Disk?
Hello everyone,
After extensive googling, it seems at first that Time Machine will not allow you to use a mounted disk image for a backup drive. I was wondering if there was a way to rig it up so that it would work, somehow disguising the mounted image as a hard drive.
My situation is as follows: I have an external FireLite Smartdisk hard drive for Time Machine backups. And yet, the drive is plenty big, while my computer's hard drive is fairly small. I want to have the backups not take up the whole drive, as they have. I attempted to partition the drive via Disk Utility, but it gave me the following error:
Partition failed with the error:
Filesystem resize support required, such as HFS+ with Journaling enabled.
I tried it with all file systems, including free space. I finally decided to try a sparse bundle disk image, with a size of 100 gb. I mounted it, went into Time Machine prefs, and it did not appear on the list of available disks.
Does anyone have any ideas?I'd quit trying to outsmart the backup system (Time Machine is picky already) and focus on the hardware. I don't have one of those drives, but I'd be looking at why you can't repartition or format the drive. Firmware? Using a hub? Does it have a USB port you can try?
Many hard drives like the MyBook series have had problems with FW on Leopard and there are firmware updates for them. The USB ports worked fine. -
No green icon for time machine disk ?
Just a very minor question:
My time machine disk now appears with the same yellow icon that is used for all "standard" hard disk drives.
Is there no more green disk icon ? Or can I set this manually ? (if so, how ?)Thanks Stef_Heck
You are perfectly right: at some stage this morning (something like 10 hours after having installed Yosemite) the icon became green automatically.
So just a question of being patient
Now 100% happy with Yosemite (while I only was 99,5% happy before.....) -
Multitasking - Have to wait for card to stop before selecting
I have noticed that when multitasking, I have to wait for the cards to completely stop moving before I can interact and touch them. I am unable to select a card while they are animating. Is this normal?
The app cards. I call them cards, I could be using an incorrect term, but the currently running app windows/screenshots/previews that you interact with by swiping up to close the app or touch to select to go into the app.

Stop Disk Full Alerts for Time Machine disk?
Hi there,
I have an alert set up on a Mac Mini server to notify me if a disk gets over 50% full. Unfortunately, this is warning me now that the Time Machine disk is getting over 50% full, which is to be expected. Is there a way to set it so I am only notified if the system disk is getting full?
Thanks!You might do better searching, browsing, or re-posting in the Server forum, at http://discussions.apple.com/category.jspa?categoryID=96

[Solved] Wait for external usb disk before mounting partition
Hello,
I have a fresh setup where 3 btrfs subvolumes are supposed to be mounted on /var /home and /opt. Those subvolumes are on an external usb drive (root fs is on a sd card).
During boot, systemd tries to mount /var first but encounter "var not empty, mounting anyway" (probably due to several boot attempts) and then "special device uUID=12f15a3e-cf5c-4bc2-9475-6b4686a30f90 does not exist" where 12f15a3e-cf5c-4bc2-9475-6b4686a30f90 is the correct id of the drive.
From journactl extract it seems that usb drive is not ready yet when /var is being mounted.
Is there a way to make systemd wait for "the disk is ready" before trying to mount /var ?
Information:
- mounting /var in rescue mode works perfectly (mount -o subvol=var /dev/sda /var)
- device is a raspberry but I think it has no link to the issue (except maybe being slow to send power to usb)
- the usb drive is behind a 4 port usb hub (externally powered)
- the usb drive indeed take some time to be powered up
- /home and /opt are mounted in rescue mode automatically a few seconds later

I have Time Machine set up on a USB external hard drive. I have noticed that if the drive in the Time Machine has spooled down, my iMac won't respond to the mouse or keyboard until that drive spools up again. This takes only a second or two, but is this normal?
Hi hopjr
Go to:
1. System Preferences > Energy Saver and uncheck ❏ Put the hard disk(s) to sleep when possible
2. The manufactures web site and check there FAQ for either a solution or firmware update.

Erasing Time Machine disk for reuse
The disk I have been using for Time Machine backups is now too small for the amount it has to back up. I would like to erase it and put it to a different use, but I don't see any option in any menu for doing this. I would like to swap it out for a bigger drive and keep the smaller one for other purposes.
Can anyone tell me how to erase a Time Machine drive so that the Mac will see it as just another hard drive?Use Disk Utility in your Utilities folder to erase the drive.
Remember, everything will be gone. -
I installed OSX 10.6.8 on iMac and now I have two icons for time machine in my dock. When I try to access either one the wheel goes round and round. I seem to have lost all back ups that were on Time Capsule. Not sure how to check or what to do. Thanks.
See what happens if you select the TM icon in your menubar, and select Enter Time Machine there.
If that doesn't help, try the things in #E4 of Time Machine - Troubleshooting -

I am having a problem with the external USB disk (500GB Iomega) that I have set up for Time Machine not remounting after my iMac wakes back up. Nothing I have tried, short of rebooting, seems to cause the Mac to notice the drive. I have tried turning the drive off and back on, but that didn't work, and neither did unplugging and re-plugging the USB cable. (I suppose obviously) Time Machine won't do any backups and complains that "The storage location for Time Machine backups can't be found." Time Machine Set Up says "Next Backup: When Disk is Connected." If I reboot, the disk will show up and Time Machine will commence backups, but then, after the machine sleeps, I have the same problem again.
When I first plugged the drive in last night the computer immediately recognized it, mounted it, and asked me if I wanted to use it for Time Machine. I didn't have to do anything. I then successfully started Time Machine and it did its initial and several hourly backups as expected. Then the machine went to sleep and the disk never came back (short of a reboot).
The computer is a brand new 24-inch, 2.8Ghz, iMac with Leopard installed from the included DVD immediately after opening the box - I did nothing before installing Leopard.
This is my first Mac (I am a Unix refugee) so I may very well be doing something entirely stupid, but surely external disks should still be mounted (or automount) after the computer returns from sleep. What am I doing wrong? I also don't see any way to force Leopard to mount the drive, but I probably just don't know where to look.
To be completely clear... the drive is plugged directly into the iMac on USB, no external hub. There is no networking involved with this disk. I didn't make any kind of settings to the disk (either to the disk itself- there aren't any, or on the iMac when I plugged the disk in). The only thing I did was answer "Yes" when Time Machine popped up a window asking if I wanted to use the new disk for backups. Last time the disk was mountet (before the computer went to sleep again) I ran the Disk Utility and it said the drive was fine.
Thanks,
Mark
P.S. I'm sorry if this has been discussed elsewhere but I couldn't find it. Like I say, I'm new to the Mac and to these forums, so please forgive me if this post is redundant.Greetings,

Ok, I went into console, and forced my iMac to sleep to see what the console would show was actually happening. I am not a very computer savvy person, but this is what the console said:
Nov 8 21:50:27 steve-freunds-computer kernel[0]: USBF: 48332.754 AppleUSBEHCI[0x52ab000]::Found a transaction past the completion deadline on bus 0xfa, timing out! (Addr: 3, EP: 2)
I believe this may be related to the problem. The AppleUSBEHCI appears to identify the offending driver/controller as the EHCI controller (Enhanced Host Controller Interface), or the controller that handles usb 2.0 High Speed (usually usb 1.1 and 2.0 Full Speed are handled by something that would be called a UHCI or Universal Host Controller Interface) USB High Speed is the fastest of the three usb speeds and although the interface is compatable with the slower speeds, works rather differently than the other two. Beyond that I'll have to look into what this message means (I'm brand new to the Mac - I've only had this one a couple of weeks).
*Could others that are seeing this problem please post how many usb ports on the computer, not total devices connected to hubs or anything, but actual, physical ports on the computer that they are using?* Experimenting a little, on mine at least, I have not had the problem discussed in this thread when only two (out of the three available) of the physical USB ports on the Mac are used. Again on mine at least, it also doesn't seem to matter what, with the exception of external hubs, is plugged into the ports. Replacing the external drive with a flash drive or iPod Touch produces the same results, so it doesn't appear to have anything to do with the Iomega drive that I started seeing the problem with - it may be that that was just the third thing I plugged in (or not - I realize that I am a sample of one).
It also seems to be that things connected to an external hub continue to work after the other two ports have failed. This is probably why most keyboards (mercifully) keep working - they are usually hubs (Apple's external ones are). I can't guarantee this however because I haven't really tested it - just observed it so far to be the case for me so far. Hubs do work differently than ordinary usb "functions" as the usb spec calls them.
Lastly...
If you have Xcode installed (assuming you have it installed in the default /Developer location) there is a tool in /Developer/Applications/Utilities called "USB Prober" that can provide some useful USB information.
In my case, once a device stops working I see the status of the non-functioning devices reported as:
High Speed device @ 2 (0xFA200000): ............................................. External HD (did not respond to inquiry - 0xe00002ed, might be Suspended)
High Speed device @ 3 (0xFA400000): ............................................. HP Color LaserJet 2605dn (did not respond to inquiry - 0xe0004051, might be Suspended)
And indeed the usb ports in question do appear to be behaving as if the host (the Mac) has them suspended - but I can't be entirely sure. I will try to look into this some more later if I can.
Thanks,
Mark
P.S. To save questions: I've tried all the easy stuff: Switched cables, swapped out the hub I have on one of the ports, tried different devices in the ports (so far an HP printer, Iomega external disk, iPod Touch, and Sony usb flash drive). Nothing resolved the issue. My keyboard and mouse are connected to a 2.0 High Speed hub. I've tried using another hub, but it didn't make any difference. -
For about a year I've been using my 1TB external hard drive for only time machine. To be honest, it wasn't until today that I tried to connect my hard drive to a PC and realize it isn't compatible. I read about partitioning the hard drive so that it can work both for time machine and transferring files between pc and mac. I'm not what you would call tech savvy, so I was wondering if I can get some advice on how to do this.
Thanks in advance.To do it, you have to partition the hard disk, so you will have one partition for Time Machine and another one to store files and use them in a PC and Mac. To create the partition, follow these steps > http://pondini.org/OSX/DU3.html
In order to read and write in the external disk on the PC, you have to select "MS-DOS (FAT)" as "Format". If you choose any other option, the PC won't be able to read your external disk. Apart from that, note that you can't use files bigger than 4 GB with FAT. If you want to use the external disk with files bigger than 4 GB, you have to format your new partition in exFAT, and you have to do it on a PC -
Time Machine disk is not unlocked automatically
I have a FileVault2-encrypted Time Machine disk connected to my MBA through a Thunderbolt display in my office (the disk is a Buffalo Thunderbolt drive).
When I leave the office, I eject the drive. put my MBA to sleep and disconnect it from the Thunderbolt display (the drive still connected to the display).
When I return in the morning I reconnect the display, wake up the MBA and log in. But then I always have to manually unlock the external drive with Disk Utility. Otherwise it won't show up in the finder and Time Machine won't make any backups. That's annoying, because I often forget this procedure and TM silently fails to make backups.
Is there a way to automatically unlock the drive when I login in the morning, just like it does when I reboot the computer?
(the passcode for the encrypted drive is in my keychain)I have had trouble twice with TM, both occasions involving similar odd messages about available space. Once on OS 10.5 and once on Lion 7.1
