At times OS slow to connect external devices.

Howdy,
I have an external HD I occasionally attach to do backups. Quite often it takes a long time for the HD to mount and also for SuperDuper! to connect to the HD and become responsive to input.
Today the same thing happened when iTunes attempted to connect to my iPhone to sync.
Any idea what is going on? Is Apple working on this problem?
Good Luck,
Herb Schulz

Howdy,
This occurs when I first connect the HD (it's a LaCie Quadra connected via FireWire800) not when it has been on for a while. Also, the HD is NOT being put to sleep via the Energy Saver Preference Pane.
Good Luck,
Herb Schulz

    Hello Jannik1810,
    Thank you for using Apple Support Communities
    To me, that sounds normal. As for troubleshooting, I would reset the SMC on the computer and see if that has any effect on it.

  • Time Machine and Occasionally-Connected External Hard Drives

    Hi
    I have a MacBook Pro. It uses Time Machine to backup over the LAN, to a USB drive which is connected to my AirPort Extreme hub. This works fine. (Extremely well, in fact.)
    Occasionally, I do video editing work. When I'm doing this work, I connect an external FireWire drive to my MacBook Pro - the FireWire drive contains all my video projects. The rest of the time, the FireWire drive is powered down.
    Is it a good idea to include the FireWire drive in the Time Machine backup? If Time Machine backs up the FireWire drive, and on subsequent backups the FireWire drive is not available, what happens to the FireWire drive backup when I enter Time Machine?
    Bruno.

    According to Disk Utility, GUID and AFP are both ok for a non-bootable drive with either CPU. The difference is when you want to make a volume bootable.
    Since TM volumes are not bootable, it shouldn't matter UNLESS you have some other bootable system installed on the drive.
    Right now, the drive on my Intel iMac is partitioned AFP and the one on the PPC powerbook is GUID. They both appear to be behaving themselves. The iMac has had one instance (since the last partition job) of a massive backup which occurred right after I changed the exclude list and the PPC has had no massive backups (other than the initial one). On that one, I built the exclude list BEFORE the initial backup.

  • Time machine backup of connected external hard drive

    Morning all,
    I've read through various posts regarding my question but most appear to be slightly vague for my understanding.
    I have a 3TB TM with a 500GB external mac formatted hard drive connected via USB. This hard drive contains music and a couple of years photos that will eventually go into iPhoto once sorted but I'd like TM to back up this hard drive for the moment.
    Upon entering TM Preferences and the Select Disk button, I have a list of backup drives that includes the external hard drive. The default backup disk is the TM.
    What I cannot understand is how to get TM to backup this external hard drive using the preferences given to me?
    Or, if, by default, this drive is being backed up, where are these settings listed?
    Many thanks
    Tim

    I have a 3TB TM with a 500GB external mac formatted hard drive connected via USB.
    Is the 500GB connected to the TC or the Mac?? I am lost but as I read that sentence the USB drive is plugged into a TC.. and the TM is a typo.. Time Machine is software on your computer.. Time Capsule is a hardware router with a hard disk,, in your case 3TB.
    TM cannot backup network drives.. plug the 500GB into the Mac and it will automatically list in exclude on TM.. you have to remove it from the exclude list to be included.. it is kind of thinking a solid state physicist would use.. holes instead of electrons.

  • Print times on slow network connection

    I�m looking for some ideas on how to resolve a problem that I�m having in a production environment. I'm also not sure if this is the correct forum to be in so if i would be better off elsewhere please politly let me know :)
    Background:
    I have a group of users that are working over private 56k Frame Relays. We are rolling out are new printer to these location to support new documents that are required to be printing. These laser printers are replacing a generic text impact printer. The new document include a lot more information than it�s predecessor. The old report was 10 k and the new report is now anywhere from 85 to 170k. This new report is being prepared by JasperReports
    Problem:
    Obviously this report is going to take longer to download before it sent to the printer, any where from 20 to 30 second to be exact. But it gets worse� some of these location have 2-3 workstations sharing the line so these times could spike to as high as 85 seconds for a single document. This report is being sent back to the thin client through a stream that is started by a print applet on the page.
    Other givens that I can not change:
    The line speed can not be changed. I don�t have anyway of making these documents any smaller
    Questions:
    Can anyone think of any solution to lower the print time? Obviously there is no application problem as it is not an issue in location with a high connection speed. I have done packet tracking for these locations and the network can not be optimized any more than it already is.
    Is there anyway to bring some of the responsibility to the client side so that we can send the information back in some other format to lower the network traffic� I�m grasping for straws here so any ideas are welcome,

    "We are rolling out are new printer to these location..."
    Is this mean that you have a printer in a single location and the users are sending print jobs over a slow frame relay?
    If that is the case one way to over come this problem is instead of sending the print job to the printer from client location you can implement a some kind of a server side application through which the users can directly order print jobs. And host that application in the same location that host the printer. Basically it should be possible to send the generated document to printer directly without having to send it to end user and then to printer.

  • Restored iMac from an MBP Backup giving problems with external devices

    Recently, I restored from an MBP Leopard OS Time machine Backup into a new iMac 27".
    Restoring process ran smoothly and took like an hour to recover my files and applications from the external disk time machine backup and after that the new iMac had everything my old MBP used to have but the OS. So far so good.
    But now I'm having problems connecting external devices, like the very same external disk to set my time machine backup or a Cannon Printer.
    The iMac can recognize and attach the external HDD (iOmega 1TB), I've succesfully formated it several times, but as soon as the backup process starts it will idle after backing 200MB or so and the HDD will be abruptly disconnected.
    Regarding the MP610 Cannon printer/scanner I used it smoothly once from this iMac, but after that it's been impossible to scan or print again, and it keeps saying it is connected to an MBP instead of an iMac!
    I already read the other related topics but my case is slightly different than those, so I will appreciate anyhelp you could provide me.

    When you say you restored, what does that mean? Did you do a full restore, installing the system from the backup onto the iMac? If so, you've probably borked the system and will have to reinstall it. See:
    http://support.apple.com/kb/HT2186
    Also, if you restored applications, it's possible some of those applications are not installed correctly or are not compatible with SL. Printing problems are common among folks who have not updated printer drivers to SL-compatible versions.

  • Recording midi from an external device

    When I record a midi pattern from an external groovebox into logic the pattern slows down during the recording and goes out of time.
    I have the external device set to "mid slave" so it should be using Logics midi clock.
    any help would be much appreciated!

    the slower machine must be used as master
    The groovebox is slower than Logic....
    I hope that it is able to send MMC.
    use Logic as Slave... or do the recording without sync
    you will be able to adjust the BPM in Logic manually after recording

  • Re: Very slow internet connection!

    Hi, have joined the forum because there isn't aywhere giving out info and I wondered if anyone could update me
    Thurs 12/7 this week I had no internet connection but I had broadband.  I contacted BT and the answer message said if there is a broadband problem they are aware of it and eta on fix was one hour - it took longer than that because the same message played much later in to the evening. I did a system restore to a date in may and temporarily access to the internet was restored for about 10 mins (suggesting a microsoft update had changed the setting somewhere)
    Fri 13/7 I contacted BT in the am and a very helpful person went through some hub resets etc but it didnt resolve problem.  I said I would call back in the evening and we would go through some more fixes.  I called in the evening and we went through the resets and the netsh reset winsock command etc and the problem was not resolved.
    Sat 14/7 I have restored the back again to May this year and again internet access has been restored.  Before losing it this time I looked up on the microsoft website for info about what is preventing access and is new on this update, amended the SSL and TSL settings and the internet access has remained. 
    Sat 14/7 with internet access restored with the new microsoft updates intact, there are problems with various website. There was an announcement this week that the east german isp that the FBI had diverted and monitored was about to be swtiched off monday 9th July.  The BBC announcement is that 500 000 websites are down as a result and a number on a different media website could be contacted about restoring their connections.  The BBC have encountered problems with their website and slowly they are resolving it and the display problems are being resolved.  All responses onthis site are slow.  Other websites not inthe UK or the USA appear to be responding at normal speed but those that are time out, slow to connect or fail to connect.  My hotmail account has been inaccessible until the last half hour andf the responses are slow so I am assuming that sites that have been "downed" are being systematically restored and the process in doing that is causing slow responses.  Does anyone have an input about this?  I am testing frequently visited sites and gradually they are connecting where before they were not and they are getting quicker
    I hope you do not mind me posting this as a reply as like you, up until these national problems this week I haven't encountered the slow responses that I have experienced over the last couple of days

    thank you Keith but I think I am fine.  The connection speed doesn't appear to be slow and my settings after the MS windows have been restored earlier today after much digging around their help site.  From reading the media today, a high number of websites were taken down this week as reported in the media and as each one is being brought back up their pages are beginning to display normally and the responses are getting faster.  Sites I couldn't access or were slow this morning are now responding at an acceptable speed.  some sites on my favourites fail to open but gradually they appear to be coming back on board so I may have resolved my own problem.
    My bank website is not accessible at the moment and I have not been able to access it since wednesday last week.  I have yet to find out why that is but I will get to the bottom of it.  It is going to be a tick in a box that has changed in my local settings since the latest ms update this week - it's just finding it.
    thank you again Keith,

  • Can anyone recommend an external storage device to supplement my mac book air?  I already have a time capsule but want the new device to replicate the data on that so ideally would like a device that i can connect to the time capsule through a cable.

    Can anyone recommend an external storage device to supplement my mac book air?  I already have a time capsule but want the new device to replicate the data on that so ideally would like a device that i can connect to the time capsule through a cable. 

    Hi CJR
    I'm not sure how Time Capsule can be replicated onto your external drive but there is a USB port on the back of TC that can be hooked up to any recent external drive.
    Another thing to think about , besides a Time Capsule failure, is the theft of your Time Capsule, so it might be a good idea to consider separating any redundant back-up from your Time Capsule or both my be stolen.
    TC will back up until full and then begin deleting the oldest back-ups.  Mine is a 2TB Time capsule.
    My back-up plan is as follows:
    1.  Macbook Air back-up on Time Capsule though Time Machine backs up everything - I think it's about every 30 min or so.
    2.  Contacts, reminders, appointments, notes, email are backed up through iCloud.
    3.  iTunes and non-itunes purchased music is on iMatch (and no need to back-up) and any non-iTunes music is backed up on an HP external drive (in case Time Capsule dies)
    4.  Photos are on my MacBook Air and are backed up on my HP external drive.
    5.  Office documents (Excel, Powerpoint, Access etc) are stored in a Skydrive app (like iCloud) and Skydrive syncs these docuemnts with the MS  cloud and my old PC and does not alter their native format like storing in iCloud would do.
    Cheers

  • Slow startup GRUB2 (GPT Hard Driver) external devices connected

    Hi,
    Anyone know why would GRUB2 init/search/scan external devices on start-up ?
    I get a long delay (i.e. an flashing rectangle (or underline, gotta check) (cursor)) as Grub2 starts when I have a CD in my computer and/or when my external Hard Drive is connected.
    I suppose it's caused by the external devices, because, when it happens, I hear sequentially my CD being worked on and my external hard drive working, then GRUB is starting (displaying the "Grub Loading..."/"Welcome to Grub" message). When I disconnect my devices and remove my CD, it all goes well and the "Grub Loading..."/"Welcome to Grub" appears nearly instantly.
    Anyone who has good knowledge on GRUB2 know what I could do to remove this delay (i.e. don't touch to the devices, let Linux do its job) ?
    Thanks,
    Totony
    EDIT : Apparently, it was the BIOS (Dell's) who was scanning my devices (despite that the boot order had the Internal Hard Driver coming first...). I still got them problem if anyone know why it does that.

  • How to make external devices (like iPods, etc.) NOT mount as connected drives when plugged in via USB to a Mac?

    If I plug my iPod (or a thumb drive or whatever) to my Mac's USB port, the device appears as a icon representing a connected drive on my Mac's Desktop.
    This is normal, expected behavior.
    HOWEVER, in some cases, I'd prefer that the device not "mount" as a connected external drive.
    With thumb drives or external USB drive, of course, I want them to "mount" so I can transfer files on or off them -- that would be the only possible reason to connect an external drive like that.
    But with other Apple devices like iPods or iPhones, there are TWO possible reasons to connect them to a Mac: either to "sync" them or transfer files on/off them; OR, to simply recharge the device's battery. (Or, both sync and recharging functions at once.)
    For those people who use their Apple devices in ways that require transferring files (i.e. most people), then having the device "mount" as a connected device is a desirable behavior.
    But in my circumstance (and I bet there are a lot of people in a similar circumstance), I have no need or desire to transfer any data to or from my device every time I plug it into my Mac: I'm plugging it in SOLELY to recharge the device's battery.
    Specifically, in my case, I have a 6th-gen iPod Nano, and I use it exclusively as an FM radio and a pedometer. I don't have any mp3s or songs or any other external files loaded on it, nor do I plan to add any in the future.
    The only reason I ever plug it into my Mac is so that I can recharge the iPod's battery.
    But the "problem," which is a minor one I admit but a problem nonetheless, is that every time I connect the iPod to the Mac, the iPod appears as a "connected drive" icon on my Mac's desktop. Which means that I'm not supposed to just unplug the iPod  when I'm done -- first, I have to find its icon on the Mac Desktop, and then drag the icon to the Trash, to "unmount" it -- and only then can I freely unplug the iPod without getting an error message telling me that I shouldn't just disconnect connected drives without first properly unmounting them.
    This would be bothersome enough if I only had to do it once per connection, but in the case of the iPod Nano, there's no way to tell how recharged it is while it is in the act of recharging, so that to see if I'm "done," I have to unplug it, check the battery status, and if it's not fully charged, re-plug it back in. So that each time I recharge it, I often have to unmount the drive several times, depending on how impatient I am.
    There has to be a way to prevent the mounting of the drives of devices that one is connecting simply for the purpose of recharging. But how?
    Strangely, I also have an old iPhone, and when I plug that in for recharging in the same way, it DOESN'T appear as a connected drive on the Desktop. I'm not sure how I managed to do this, but long ago I must have changed some setting or preference for this to happen. And by now I've forgotten what I did.
    I'd prefer that I could change the "mount/don't-mount" setting on a device-by-device basis -- i.e. make it such that this particular iPod doesn't load, but perhaps a different iPod would load -- but if that's not possible, then is there a way to stop ALL iPods and iPhones from loading as connected drives when plugged in?
    (I'm not talking about appearing as connected drives within iTunes -- I'm talking about appearing as an icon on the Desktop in the Finder.)
    And please don't tell me to just buy a wall charger! I prefer to recharge off my computer if possible, using the charging cord that came with the iPod.
    I presume there's some simple setting to toggle this on or off, but I haven't yet found it. Any clues would be appreciated. Thanks!

    Well, I already know about that Finder Preferences option, but that is not what I'm looking for. Why not? Because I still need CDs and DVDs to appear on the Desktop and mount properly! If I uncheck the "CDs, DVDs and iPods" option, then I lose the ability to access CDs and DVDs, which creates a whole new problem for me. What I want is to not mount iPods only -- actually, what I really want is to not mount this particular iPod -- but if that level of specificity is not possible, then I want to exclude just iPods from mounting, without also condemning CDs and DVDs (or whatever) to invisibility.
    Also, I was confused by the way the Preference is worded: It says "Show these items on the Desktop," with a series of options to check. But this phraseology seems to mean that the unchecked items will still "mount," they simply won't appear as Desktop icons. One would still have to "Eject" them using a menu command, rather than dragging the icon to the Trash -- right? Or am I mistaken, and is the Preference Pane simply badly worded, and when they say "Show these items on the Desktop," what they really mean is "mount these external devices as connected drives." So that if a category is unchecked, then they won't load as external drives at all?
    But if so, then what purpose could possibly be served by inserting a CD or DVD that is not recognized by the computer? And if it isn't recognized, then it would seem that there would be no way to ever Eject the CD or DVD disk. Right?
    Thus, if I uncheck that Finder Preference box you suggest, one of two outcomes will result:
    -- Either CD, DVDs and iPods are still mounted, they just won't appear as icons on the Desktop; but they would still need to be Ejected via a menu command, which doesn't solve my problem.
    -- Or, CDs, DVDs and iPods are not mounted or recognized by the computer at all, which means that if I insert a disk into the disk drive, it will get stuck there forever, since there's no way to Eject it, since the OS doesn't recognize that it's even there. Which is thereby a new problem.
    Either way, I'd have a problem! Or...? Clarification, anyone?

  • Can I use Time Capsule 1TB as an external hard drive tos tore my music library(but with cable connection,not WI-FI)

    Can I use my Time Capsule 1TB as an external hard drive to store my music library but with a cable connection(Ethernet or USB) and not Wi-Fi.

    Yes, with the following warnings.
    1. A 1TB TC is a Gen3 or earlier and can die at a moments notice.. So backup is essential.
    2. A Gen1 or 2 is slow.. even over ethernet they were processor bound and so transfer speeds are not great.. a USB2 plugged into the computer will be faster. Gen3 is about 50% better as the processor was upgraded by 50% speed.
    3. TC has no built in backup.. TM cannot backup network drives.
    4. TC is designed to spin up slowly and spin down quickly.. you will have issues with itunes constantly losing the library.
    5. You cannot use USB to the TC.. it is a network drive. If you want to use USB directly on the computer buy a USB drive.. but buy as fast a drive as your Mac supports.. Thunderbolt>USB3>FW800>USB2
    USB3 is cheap and very good.. but the port is only from 2012 so check your Mac specs.
    Thunderbolt whilst being super fantastic and around since 2011, has a bank account clearing price although there are Thunderbolt to esata converters.. for around $160. esata falls between usb3 and fw800.
    FW800 from WD is no better than USB2 but other brands it can be twice the speed of usb2.
    USB2 is the worst. But still faster than a TC.
