Airport Extreme crashes when transferring files in iTunes

Hi guys!
I'm running itunes library off an airdisk for one of my computers, it works fine when i play music from it but it crashes my airport extreme every time i try to edit or add music into the library. it will just say that i'm disconnected from that drive after itunes hangs for about 5 minutes and my network (internet, home network, airdisk) will stop working until i restart my router.
i've had similar set up before with a G5 and never had an issue, but that was on ethernet, my new setup is through wifi. I've read that there was an issue when transferring large files from computer to airdisk over wifi, but i didn't see the issue in finder, this only happens in itunes.
i have itunes 10.0.0.1 and the lasted firmware for airport extreme. I've tried simply dragging the files into my itunes and even tried using home sharing to transfer songs from another computer with a local itunes library, both crash the router. I ended up dragging one album at a time (about 10 songs at a time), it works for the first few transfers, but eventually locks up after awhile.
Did a bit of research, some say it's might be some kind of channel interference, did a little istumbler and it only showed very little noise so i'm not sure that's the case. is anyone else experiencing this? thanks in advance!

The fixed IP address solved the problems I was having with Time Machine and I did verify that the problem was not Time Machine but any disk access, however yes, it is possible that iTunes is having a problem dealing with a networked disk. I don't think it's the way that Apple really intended it to work, with the iTunes library on a networked disk, however you might be able to come up with some work arounds to make it work. Here's some suggestions if the fixed IP does not solve the problem:
Copy files you want to import to the drive first using the Finder. Put the files in the folder where all your music is automatically sorted if you have "copy to iTunes folder" and "organize iTunes folder" selected in preferences. What you should have now is all the artist named folders and then the new music all listed in this directory. Sort the window in list view so all the music and the folders are separated to make it easier to select the music. Now drag the music into iTunes. If it's in this folder, the files should not be copied into iTunes. They should just get linked to and then moved into their proper folders. It would also help diagnosing the problem if you could find out whether copying the same files using the Finder did work, so you would be looking for a work-around and also further diagnosing exactly what the problem is.
If you have an external USB drive, you could use that instead and plug it into the Time Capsule for access, but into the computer just when you need to manage/add to the media on the drive.
Another problem you are likely to come across is if you attempt to play back video content, especially HD content. I don't think iTunes expects the media to be on a network drive and therefore does not buffer sufficiently to play the content smoothly like it does if you were streaming the media to an AppleTV, for example.

Extreme N (gig E) crashes when Transfering files

I bought the new Gig - E version of the Airport Extreme and connected a USB disk. It mounts fine, and mostly works.
Unfortunately, when ever I do a large transfer job (hundred MBs for example), the router crashes. The disk transfer stalls, but the internet still works for a few minutes. The router then fails completely. I typically have to unplug it to get everything back.
Is anyone else having this problem? It is a known issue, or do I have a hardware problem?

I've been having exactly the same problem.
I'm trying to transfer a large number of files from a network drive to a Buffalo 500gb external drive attached to an AirPort Extreme N.
The drive is formatted Fat32 and works fine until sometime during a long file transfer session. It eventually hangs the Airport, requiring a cold restart.
I wonder what's going on... it's got the most recent firmware updates.

I purchased a new MacBook Pro and when transferring files iphoto did not transfer. I have a question mark in the place of the icon. My pictures are in library but can't properly access iphoto. Thank you

Sure-glad to help you. You will not lose any data by changing synching to MacBook Pro from imac. You have set up Time Machine, right? that's how you'd do your backup, so I was told, and how I do my backup on my mac. You should be able to set a password for it. Save it. Your stuff should be saved there. So if you want to make your MacBook Pro your primary computer, I suppose, back up your stuff with Time machine, turn off Time machine on the iMac, turn it on on the new MacBook Pro, select the hard drive in your Time Capsule, enter your password, and do a backup from there. It might work, and it might take a while, but it should go. As for clogging the hard drive, I can't say. Depends how much stuff you have, and the hard drive's capacity. As for moving syncing from your iMac to your macbook pro, should be the same. Your phone uses iTunes to sync and so that data should be in the cloud. You can move your iTunes Library to your new Macbook pro
you should be able to sync your phone on your new MacBook Pro. Don't know if you can move the older backups yet-maybe try someone else, anyways,
This handy article from Apple explains how
How to move your iTunes library to a new computer - Apple Support''
don't forget to de-authorize your iMac if you don't want to play purchased stuff there
and re-authorize your new macBook Pro
time machine is an application, and should be found in the Applications folder. it is built in to OS X, so there is nothing else to buy. double click on it, get it going, choose the Hard drive in your Time capsule/Airport as your backup Time Machine and go for it. You should see a circle with an arrow on the top right hand of your screen (the Desktop), next to the bluetooth icon, and just after the wifi and eject key (looks sorta like a clock face). This will do automatic backups of your stuff.

Is there a way to turn off using ram as intermediary when transfering files between 2 internal hdds? (write cache is off on all drives)

right forum? first time here. none of the options seem perfect. so i guess this applies to 'setup.' i tried to describe what's happening verbosely from the start of a file transfer to completion of writing file to 2nd hard drive.
win 7 64bit home - i2600k 3.4ghz - 8gb of ram - 2hdd 1 ssd
I have this problem when transferring files between 2 internal hard drives. one is unhealthy (slow write speeds but not looking for advice to replace it because it serves its unimportant purpose). so, the unhealthy drive drops into PIO mode - that's acceptable.
however, a little over 1gb of any file transfer is cached in RAM during the file transfer. after the file transfer window closes, indicating the transfer is "complete" (HA!), it still has 1gb to write from RAM which takes about 30minutes. This would
not be a problem if it did not also earmark an additional 5gb of ram (never in use), leaving 1gb or less 'free' for programs. this needlessly causes my pc to be sluggish - moreso than a typical file transfer file between 2 healthy drives. i have windows write
caching turned off on all drives. so this is a different setting i can't figure out nor find after 2 hours of google searches.
info from taskmanager and resource monitor.
idle estimates: total 8175, cached 532, available 7218, free 6771 and the graph in taskman shows about 1gb memory in use.
at the start of a file transfer: 8175, 2661, 6070, 4511free and ~2gb of ram used in graph. No problems, yet.
however, as the transfer goes on, the free ram value drops to less than 1gb (1gb normal +1gb temporary transfer cache +5gb of unused earmarked space = ~7gb), cached value increases, but the amount of used ram remains relatively unchanged (2gb
during transfer and slowly drops to idle values as remaining bits are written to the 2nd hard drive). the free value is even slower to return to idle norms after the transfer completes writing data to 2nd hard drive from RAM. so, it's earmarking an addition
5gb of ram that are completely unused during this process. *****This is my problem*****
Is there any way to turn this function off or limit its maximum size. in addition to sluggishness, it poses risk to data integrity from system errors/power loss, and it's difficult to discern the actual time of transfer completion, which makes it difficult
to know when it's safe to shutdown my pc (any data left in ram is lost, and the file transfer is ruined - as of now i have to use resmon and look through what's writing to disk2 -> sometimes easy to forget about it when the transfer window closed 20-30minutes
ago and the file is still in the process of writing to the 2nd disk).
Any solution would be nice, and a little extra info like whether it can be applied to only 1 hard drive would be excellent.

Thanks for the reply.
(Although i have an undergrad degeee in computers, it's been 15years and my vocab is terrible. so, i will try my best. keep an open mind. it's not my occupation, so i rarely have to communicate ideas regarding PCs)
It operates the same way regardless of the write-cache option being enabled. It's not using the 5gb for read/write buffer - it's merely bloating standby memory during the transfer process at a rate similar to the write speed of destination (for my situation).
at this point i don't expect a solution. i've tried to look through lists of known memory leaks but i dont have the vocabulary to be 100% certain this problem is not documented. as of now it can't affect many people - NAS's with low bandwidth networks, usb
attached storage etc. do bugs get forwarded from these forums? below i can outline the consistent and repeatable nature not only on my pc but on others' pcs as well (2012 forum post i found).
I've been testing and paying a little more attention and i can describe it better:
Just the Facts
Resmon Memory Info: "In Use" stays consistent ~1gb (idle amount and roughly the same when nothing else is running during file transfer)
"Modified" contains file transfer
data (meta data?) which remains consistent at little over 1gb (minor fluctuations due to working as a buffer). After the file transfer window closes "Modified" slowly diminishes as it finishes lazy writing (i believe that's the term). I forget idle
pc amount, but after transfer this is ony 58mb)
"Standby" as the transfer starts it immediately rises to ~2gb. I'm sure this initial jump is normal. However, it will bloat well over 5gb over time with a large enough transfer increasing at a consistent rate during the entire transfer
process. the crux of the matter.
"Free" will drop as far as 35-50megabytes over time.
as the transfer starts, the "Standby" increases by an immediate chunk then at a slow rate throughout entire transfer process(~1mb/s). once writing metadata to RAM no longer occurs, the "Modified" ram slowly (@500kb/s matching resmon disk
activity for that file write) diminishes as it finishes lazy writing, After file is 100% written to destination drive, "Standby" remains a bloated figure long after.
a 1.4gb transfer filled 3677MB of "Standby" by the time writing finished and modified ram cleared. after 20minutes, it's still bloated at 3696MB. after 30-40mins it's down to 2300mb - this is about what it jumps immediately to when transfer starts
- it now remains at this level until i reboot.
I notice the "standby" is available to programs. but they do not operate well. e.g. a 480p trailer on IMDB.com will stop-and-go every 2-3seconds (stream buffers fine/fast) - this would be during the worst case scenario of 35-50mb "Free"
ram. my pc isn't and never was the latest and greatest, but choppy video never happens even with 1 or 2 resource hogs running (video processing/encoding, games, etc).
Conjecture Below
i think it's a problem when one device is significantly slower at writing than the source device - this is the factor that i share with others having this problem. when data is written to modified ram then sent to destination, standby memory is expanded
until it completely or nearly fills all available RAM - If the transfer size is large enough relative to how slow the write speed of destination device is. otherwise it fills it up as much as the file size/write speed issue allows. the term "memory leak"
is used below but may not technically be one, but it's an apt description in layman's terms.
i saw a similar post in these forums (link at end). My problem is repeatable and consistent with others' reports. I wasn't sure if i should revive it with a reply. some of these online message boards (maybe not this one) are extremely picky
and sensitive, lol.the world will end if an old thread revives - even if for a good reason.
i can answer some of the ancillary issues. one person (Friday, September 21, 2012 8:33 PM) mentions not being able to shutdown, i asume he means stuck on the shutdown screen - this is because lazy writing has not completed - his nas write speed is significantly
slower than reading from source - the last bits of data left in ram still needs to be writen to the destination. shutdown will stall for as long as needed until the data finishes writing to destination to prevent data loss.
another person (Monday, September 24, 2012 6:31 PM) mentions the rate of the leak, but the rate is more likely a function of read speed from source relative to write speed of destination. which explains why my standby expands closer to a 1:1 ratio compared
to his 1:100 (he said 10mb per 1000mb)
we all have the same exact results/behaviour, but slightly different rates of bloating/leaking. as the file is written from from the ram to the destination, standby increases during this time - not a problem if read and write speeds are roughly equal (unless
your transfering a terabytes then i bet the problem could rear its head). when writing lags, it gives the opportunity for standby ram to bloat with no maximum except the amount of installed ram. slower the write speed, the worse the problem.
The reply on Wednesday, September 26, 2012 3:04 AM has before and after pictures of exactly what i described in
"Just the Facts". Specifically the resmon image showing the Memory Tab.
The kb2647452 hotfix seems to do some weird things relative to this problem. in the posts that mention they've applied it: after file completes it looks like the "standby" bloat is now "in use" bloat. as per info from Tuesday, October
09, 2012 10:36 PM - bobmtl in an earlier post applies the patch. compare images from earlier posts to his post on this date. seems like a worse problem. Also, his process list indicates it's very unlikely they add up to ~4gb as listed in the color coded bar.
wheres the extra gb's coming from? likely the same culprit of what filled up "standby" memory for me and others. it looks like this patch relative to this problem merely recategorizes the bloat - just changes the title it falls under.

I have my iTunes library stored on an external hard drive which is connected to my airport extreme, I wish to share my iTunes library over my network, I can do this with my laptop, but not with my iPad, can anyone tell me if it is possible

You can't connect directly to the external drive, but should be able to use iTunes Home Sharing via the laptop.

Mac Mini Mid 2011 General system slowdown when transferring files?

Hi i have a stock mac mini mid 2011, 2.5ghz i5, 4gb ram, 500gb HDD os 10.7.1 and i've noticed a general system slowdown when transferring files on 10.7 and the last 10.7.1 update ( from usb to hdd, another computer on my local network to the mini, external dvd to the mini, etc).
I could describe the slowdown as mouse pointer movement suffers, its "laggy", application take longer to start, even menus in them from appearing, writting something on the keyboard i have to wait like 5 - 10 seconds so the words start appearing in the app (i.e. textedit).
I wanted to know if any other new mac mini owner has had this issue and if there is any solution to this(that would not involve buying a SSD for example)?
Im not really sure if this is a hardware or system issue but it really is getting on my nerves(i know i could just wait for the files to transfer which is what i do now but i dont think that should be), since i also have a old macbook from 2007 2.0ghz c2d, 2gb ram, 250gb HDD os 10.6.8 and have never had this problem before.
Thanks in advanced.
Let me know if i need to give more info on this subject.
Edit: I forgot to mention, the funny thing is doing a time machine backup to my external HDD or transferring files from my HDD to a usb doesnt give me any kind of slowdown.

Hi Rick, I'd see if it's reated to this, which has many symptoms...
Try this: "sudo pmset autopoweroff 0" and "sudo pmset standby 0"

My firefox crashed when upload file on our web based application. This happen on two PC, even during firefox safe mode the problem still exist. But the problem

Dear All,
My firefox (version 23 on win 7) crashed when upload file on our internal web based application. This happen on two PC, even in firefox safe mode the problem still exist. So, my first conclusion the problem nothing to do with extension. here the crash ID https://crash-stats.mozilla.com/report/index/81220865-36c0-4e10-a484-6d27e2131023 and https://crash-stats.mozilla.com/report/index/86d2b779-9730-4d2c-b276-a86d42131023. I wonder if this happen because jquery modul in our web based application. But when I tried on my laptop, the problem dissapear. I tried to replicate same situation on different server, I mean I put the exact same application source to other server, never meet the same problem. Thus, I suspect may be it related to antivirus that installed in our network which is kaspersky. I am googling, never meet the clue.
If you meet the same problem, please help me.
I am so sorry for my poor english.

Sound Buzz when transferring file from Trash to desktop

I get the occasional Sound Buzz when transferring file from Trash to desktop
Its a Short "grounding" buzz similar to slowly plugging an electric guitar when the amp is on, but its loud !
I am just using the internal sound,

Brett - thanks for that input, but as stated in my original post this happens whether I do the copy within Finder, or from inside Bridge.
Your note did inspire me to try one thing though: I UN-checked my Bridge preference to export caches to folders when possible, then I went to the folder I was trying to move (on the NAS) and did Tools > Cache > Purge Cache. I found that if the folder contained only files and no other folders, then I could move the folder to my desktop. However, if the folder in question had nested folders, then I still run into the same conflict.
Question: since this conflict does not happen when moving a folder from one computer to another computer (but only from the NAS to a computer), I'm not sure how your logic holds when you say "Bridge is trying to cache the files you are moving and creates a ".BridgeCacheT" file before the remote version is copied"
To answer your other question, we use AFP or at least is says "afp://server.local" when we connect. My apologies for not being an expert on this. The icon of the NAS on the desktop looks like the icons for the other computers.
Thanks, I'm still trying to solve this. It's really become a major problem for us as we now have to drag files individually (rather than by folder) when we want to do something with them. -- Jim

Finder is crashing when previewing files

My finder keeps crashing when previewing files from an external hard drive. It's mov-files and stills(cr2).
I have files recorded on two separate days. When previewing files day 2 there's no problem but when previewing files from day 1 finder is crashing every time. I have back up of all the files on another drive. On the back up drive there's no problem to preview files.

That is why I want you to erase it.. so you can get access.. but I cannot trial it for you... I do not have one.. you have to trial it yourself.
Setup the TC to use Accounts.. not use disk password or device password.. after an erase.
See if that fixes it.
See this post for different but maybe related issue.

Premiere Pro crashes when sending files to media encoder

Premiere Pro CC keeps crashing when sending files to Media Encoder. This is a new problem. I cleaned the cache, typed purge into terminal, checked the sharing in the preferences library and verified/repaired disk permissions. What else can I try? Help, I have urgent deadlines this week!

I am using the most updated version of PPro CC with OS 10.8.5. It seems to have issues with certain sequences and not others. It also may be the files themselves. They play fine in the program viewer and I have sent them to Media Encoder before, but if I create a new sequence with the same settings and copy the files into it, the same thing happens. I have a lot of 29.97 720x480 (1.21 pixels) and 1440x1080 (PAR 1.333) footage to edit together and create dvds out of (not my idea - it's a job) and I am in the middle of trying various ways of encoding to make it as clear as possible.
Currently I am using 1440x1080i HD anamorphic sequence settings encoding into 1440x1080 p HD anamorphic with frame blending, maximum render quality, Target bit rate of 30 VBR 2 pass. Then combining those files with other sequences into a longer 1440x1080 p HD anamorphic sequence and encoding MPEG 2-DVD NTSC widescreen progressive 100% quality, VBR 2 pass and the output is much better. This has been working, and today suddenly it stopped and started crashing. Any ideas?

Can you use airport extreme 802.11n for files backup

Can you use airport extreme 802.11 for files back up and sharing

You can if you connect a hard drive that has been formatted correctly to the USB port on the AirPort Extreme.
Apple does not officially support Time Machine backups for this type of setup, but you could store regular files this way.

Why does system suite pro 12 crash when running file cleaner is running while firefox is installed? If I uninstall firefox then system suite pro 12 won't crash.

When I downloaded the newest version of firefox system suite pro 12 crashes when running file cleaner after I uninstall firefox system suite pro 12 doesn't crash. I have window 7 premium home edition 64 bit.

You should know a few things before before getting started:
1. Registry "cleaners" and "system optimizers" like SystemSuite are very unreliable, cause more problems then they propose to fix, have little to no benefit, and are somewhat of a scam. Running them on a system is almost guaranteeing a crash or hiccups somewhere along the process. running them is never a good idea. all you need is a good, simple, free anti-virus (like Microsoft Security Essentials), and use the built in Windows Utilities to clean and sped up your computer if needed.
2. This is a Firefox forum, so if you are having a problem with SystemSuite, we might not be able to help you.
I'll give you a few things you can do to see if this is just a Windows problem:
Run all Windows Updates, install all needed service packs, etc.
Update your graphics driver (Firefox uses your graphics card for some rendering, and an out of date graphics card driver can cause problems. [https://support.mozilla.org/en-US/kb/how-do-i-upgrade-my-graphics-drivers https://support.mozilla.org/en-US/kb/how-do-i-upgrade-my-graphics-drivers].
Update all your plugins (Flash, Java, etc.): [http://www.mozilla.org/plugincheck/ http://www.mozilla.org/plugincheck/].
Download and Install MalwareBytes Anti-Malware, run a full Scan. [http://www.malwarebytes.org/ http://www.malwarebytes.org/]. This helps check that there are no viruses on your computer causing issues. You can uninstall this program after you clean off any infections.
Plus, I'd strongly recommend removing systemsuite and any other "optimizers" you might have.

IPhone 5s connect to airport express but when I play in iTunes no option to pick airport ?

iPhone 5s connect to airport express but when I play in iTunes no option to pick airport ?

If anyone would like to know how to fix this, I discovered the answer.
I have no idea what IPv6 is and I care not, but apparently now, all of a sudden, Apple makes iTunes talk to Airport Express units using IPv6. However, it didnt bother to make the Airport Express units expect this first, so iTunes can see the Airport Express, but it cant talk to it.
Anyway, I found that you have to manually go into your Mac settings (scary stuff if you are a non technical person like me) and turn off IPv6.
To do this, go to "Finder > Go > Utilities > Terminal"
type
networksetup -setv6off Wi-Fi (hit enter)
Then type
networksetup -setv6off Ethernet (hit enter)
and magically your iTunes will talk to your Airport Express units again.
I presume at some point we will have to undo this as technology moves on and everything uses IPv6, so when that happens go into Terminal again and type
networksetup -setv6automatic Wi-Fi (hit enter)
Then type
networksetup -setv6automatic (hit enter)
Thanks Apple for that.
