File Copied to Maxtor Shared Storage NAS Drive Disappearing?

I attached a new Maxtor Shared Storage II (500 Gb) drive to our wireless router, and have discovered problem with disappearing files when trying to copy a local file to a folder in the NAS drive.
Open a window to an empty folder on the NAS drive. Drag a file on the desktop of the local machine to the folder. File appears to be successfully copied.
However, looking at the info bar of the target window immediately after the copying operation shows that the folder contains TWO files (even though only one is shown in the window). After a few seconds, the file disappears and the window shows 0 files. There is no error message.
The desktop file I'm trying to copy has an image icon (as with many files in Leopard). However, the file in the NAS folder window always shows a generic Preview icon during its brief existence.
This happens about 75% of the time.
Occasionally, the window does show two files after copying, and both files will disappear. When this happens, one of the files has a generic Preview icon, and the other has an Acrobat icon.
Other times, the drag and drop produces no files on the target window and no error message.
The file that shows the problems is this file: http://www.businesslink.gov.uk/Promotionsfiles/businesslinkgovukrun.pdf
I'm running Leopard 10.5.1, everything up to date. Can anyone shed light on this problem?
What seems to me to be happening is that when Leopard copies a file with an image icon, it copies the icon separately from the file. After the copy, it ties them up together. If something is not quite right, it can't "bundle" the icon with the file, and the copy operation falls down.

This seems to me related to this problem

I think it's the mixture of wired and wireless in combination with certain routers.

Maxtor Shared Storage (NAS) + Airport Express problems

Dear forum readers and network pundits,
I have just recently bought a 500Gb Maxtor Shared Storage (MSS) ethernet drive, to which I'm planning to make regular backup of files from my wirelessly connected MacBook Pro and Mac Mini. Both computers are connected to the Internet via Airport Express, which, in turn, is connected to a router/modem. The MSS is attached to an RJ45 socket on the modem, next to the Airport Express RJ45 cable.
The problem is that I cannot seem to make a proper connection to the MSS. I can access the drive's web interface through Safari, but I cannot mount it as a network drive in the Finder. When hooking up my MacBook Pro to the router/modem directly using a RJ45 cable everything works like a charm, so I know the drive works fine. The problem seems to be the transition from the wired router to Airport Express.
I'm no network wizard in any way. When things don't work from the start I'm left scratching my beard, which is why I turn to the vast bank of knowledge contained here. Please help me. Is there a button in the Airport Express settings I can push to make it work, or do I need to by more hardware?
Looking forward to your help.
Cheers,
Andreas
P.S. I'll churn out brownie points by the bucketload for any helpful answers

Lightroom loses files on a Network Attached Storage (NAS) drive

I am using Lightroom 5.7 on a PC in Windows 7 64-bit.
A couple of weeks ago I installed a Network Attached Storage (NAS) system as I was running out of internal hard disk space. I set up a logical drive on the NAS for Photos. In Lightroom, I dragged the photo files over onto the new drive. The catalogue and backup files remained on the internal hard drive.
My photos are arranged chronologically, in directories (years) and subdirectories (days, named using the format "2014_12_31").
Since moving the files to the NAS, Lightroom has been giving me error messages when in the Develop module that it cannot find files. The previews view fine in the Library module, and the files are still there when I look for them in Windows Explorer. The errors do not occur within entire directories (years) subdirectories (days) - only some files within individual subdirectories are affected. And, only files from 2015 seem to have the problem. And, when I drag the directories back to my internal hard drive (again, within Lightroom), the errors disappear and everything works fine.

Yes, right clicking on the problem folders and showing in explorer does show the connection is to the correct folder location.
A couple more points that may be worth mentioning:
When I was having this problem earlier this week, the missing photos seemed to be spread randomly within different folders and subfolders (folders are year, with subfolders for each day I have photos). I followed the advice in the document you referenced yesterday, and went back through each main folder (there are about a dozen of them, one for each year plus a few miscellaneous folders) and used the "update folder location" function. This worked well I thought - except I realized later on that one year (2014) still had the photos missing - but this time, it seems to be all photos within that year folder, not just a few random ones. There is no "?" on the folder, or "!" on the individual photos, they show fine in preview, but clicking on the develop module every photo has the message "cannot find file". When I right click on the folder, or individual files to follow the location of the file in explorer, the location is correct - and as far as I can tell the locations and structure is consistent with the folders for all the other years which Lightroom has no problem finding. That is, I can see nothing "unusual" about the folder for 2014 in the way it sits within my filing structure.
And here's the kicker - last night I made a copy of the entire 2014 folder that was on the NAS external drive (where Lightroom can't seem to locate the files) back on to my internal drive (this took a couple of hours). This morning, I forced Lightroom to lose the link to the folder on the network drive by simply changing the name of the folder from within windows explorer, and then the "?" and "!" warnings popped up in Lightroom indicating it could not find the folder and files. I then used "update folder location" to point Lightroom at the copies that were now on the internal drive, and the problem disappeared (all files were located).
Finally, I then broke the link to the folder on the internal drive by changing the name of the folder on the internal drive from within explorer, renamed the folder on the NAS drive back to "2014", then opened up Lightroom again (and of course it indicated the files were missing) and used the update feature again to point Lightroom back to the folder on the NAS. And, again, the missing files errors pop up for every photo within that folder - but no "?" or "!" warnings are shown (recall these are an exact copy of the files that it had no trouble finding on the internal drive).
I tried playing various games with Lightroom last night, forcing it to break linkages by renaming folders, etc, and every time when I use the update file location feature it has no trouble reconnecting, whether the folders are on my internal drive or the NAS. So, this functionality seems to be working within Lightroom and I know how to use and abuse it. BUT, it steadfastly refuses to reconnect with the 2014 folder when it's on the NAS, but has no trouble reconnecting when pointed to an exact copy of the same folder on my internal drive.
I'm kind of at my wits end here. There seems to be some sort of bug in Lightroom that makes it lose it's wits when connecting to photos on a NAS drive. Or, I'm doing something really wrong that isn't obvious......

NAS Problems! Maxtor Shared Storage II not accepting long file names

Somebody help me!!!! Maxtor Shared Storage II. can't accept beyond certain filename length. And Maxtor says its Mac compatible. What a bull! Now, is there a way for me to do it via ethernet? Or do I have to use a usb cable with matching ends? And once I've reformat it, will everything works just as fine as well? I mean all the capability of the RAID and network?
Cheers!

Thanks for the technical jargon thingy – the hatter – I've been spending the couple of my sleepless hours finding out about the problem that I have came across that FAT32 thingy numerous times.
Next month I'll be turning 32. Lucky for me, I'm not FAT and make sure I won't otherwise I start becoming 'Mac-unfriendly' even though I'm definitely am very compatible.

Backing up to Maxtor Shared Storage II

trying to backup files from mb pro to maxtor shared storage II. noticed not all .jpg's copied over and no other information (e.g., .doc's, etc.). any help appreciated including if easy way to ensure all documents (.jpg's, .doc, etc.) copied over.

The best way is with http://www.bombich.com/ 's Carbon Copy Cloner using simple cloning after formatting the hard drive with GUID partitioning. If you must connect to a PC, consider networking via the PC, or using Macdrive software to read it.

Existing files on drive connected to latest Airport Extreme do not show up, however files copied over the air to the drive do. Any ideas?

I have the latest Airport Extreme with a Seagate drive connected. I copied files to the drive while it was connected to my MacBook Pro. The files do not show up when connected to the AE, but they appear when connected to the Macbook, Files copied over the network to the drive appear. The drive is formatted HFS+.

After playing with this for the last few days, I found a solution. Under the "Disks" tab in Airport Utility, the "Secure Shared Disks" drop down needs to be set to "With device password". Mine was set to "With acounts", which even after correct authentication, none of the files would appear.
Another interesting note: The files that I could see, the ones I copied over the network, do not appear now. I can copy over new files, and they show up, but the ones copied prior to changing the "Secure Shared Disks" option, do not.

Suggestions on how to connect iMac *directly* to Maxtor Shared Storage?

i know that using Time Machine to back up to my Maxtor Shared Storage over my network isn't an option right now... So in the meantime, I would like to just connect my Maxtor drive directly to my iMac -- but I can't figure out how.
There is no way to connect it via USB, and there is no firewire port. The Apple guy at Best Buy said to use the ethernet cable to connect the external hard drive to my iMac, but I can't get my iMac to recognize the drive that way.
Any suggestions?
Thanks!

Right now my Maxtor drive is connected via a router no problem... But In order to use Time Machine, the drive needs to be directly (via cable,etc) connected to my iMac...
There is no firewire port on my Maxtor drive.
I did go to Best Buy (and Office Max, and Office Depot) to buy a USB cable... The cable I need doesn't exist... For example they are like this:
http://www.coolgear.com/images/as340823as.jpg
But BOTH my iMac and Maxtor drive have ports that take the USB cable-end shown on the left in the image above. There is no cable that is the same on both ends...
So, how do I get my computer to recognize/mount my Maxtor drive when I connect it directly to the iMac via ethernet cable (that is what the Apple guy at Best Buy told me to do)? I can't find anything at all in the Maxtor documentation about this...
Thanks for reading...

ITunes, with Maxtor Shared Storage.

Hi Guys,
I've set my iTunes Music Folder location to that of my Maxtor Shared Storage drive (where all my music is) but none of my music is displayed in iTunes? What am I missing here? I have a music folder plus lots of sub folders, I've tried doing a reset but no luck.
Need some help

gtiskin, Welcome to the discussion area!
Perhaps you should ask this in the iTunes discussion area or the Tiger (10.4) networking discussion area.

The other computers are showing the folder locked as well.
HELP!

We were able to unlock the folder from an old mac running OS 9 and change the permissions.
Thanks to a post from user MadDog.

How can I improve NFSv3 file performance with MythTV thru a NAS Drive?

Basically, I have both my MythTV combined frontend/backend machine and a NAS Drive connected via gigabit ethernet connections.
The NAS drive stores my recordings, shared via NFSv3 (because that's all the NAS drive came with, unfortunatly).
Now, my problem is that I can record or watch multiple *seperate* HD files simultaneously, travelling back and forth from the NAS without problem.
However when I try to watch the same file *While it's still being recorded*, after around 20 minutes the network connection is full/overloaded (between the mythserver and the NAS drive) and playback grinds to a halt (It doesn't stop the recording, just the playback).
It used to happen much quicker when I was only using a 100mb connection.
As i've said, this doesn't happen at ALL with seperate files, just only if i watch the *same* file that's being recorded at the same time.
Is there anyway (bar just having the recordings on a Hard Drive within my backend) that I can stop this problem? Is it because I use NFSv3 on the NAS drive? are there any options I can change in the /etc/exports file on the NAS drive that would help? Thanks
If you want me to post what my NAS drive (Readynas Duo V2) has in its /etc/exports file, I will

Post the file but I dunno how many Archer are using NFSv3... ;/

Sharing a NAS drive between 2 PCs running itunes with different accounts....

I have 2 Windows 7 PC's with different iTunes accounts, both accessing the same NAS drive for their save location.
2 Questions:
- 1 - How do I stop them from reverting back their default save loaction ( from "z:/itunes/itunesmedia" to "c:/user/music/itunes/itunesmedia" ) ??
- 2 - when one account buys music and save it to the NAS location, will the other itunes account be able to see it straight away, and if not, how do i make it so it does??
Any help is good help
Thanks
Jack
All itunes is running 10.something....
All Pc's autherised to play the other accounts music etc......

You can manually add the music files on the external drive to your powerbook's itunes by using File->Add to library but that won't bring over playlists, ratings or playcounts.
This "metadata" is in a file called "iTunes Library" on your desktop in Music/iTunes. To bring over that "metadata" you can try this:
1) Close iTunes on both machines.
2) Copy the "iTunes Library" from the desktop and put in in the same place on the powerbook.
3) Now open iTunes on the powerbook.
This will definitely work if the external drive is attached directly to the powerbook. I haven't tried your type of scenario, where you will access the external drive through the network to get to the desktop and then the external drive. But I think I've seen other here say this works.
If it doesn't work, ie it put exclamation marks next to tracks to indicate it can't find htem, then go into the preferences (Advanced, general) and set the music folder location to the external drive (through the network, through the desktop). This should make it find the music.
You'll also want to make sure "Copy files to the music folder" is ON so that any music you add through the powerbook is copied to the external drive. (If that's what you want. You may chose not to do this, to have some music stay on the local harddrive so you have acess to it when you're not at home).

Copying large iPhoto library to NAS drive - why is it so difficult?

I have a 2009 iMac, and a large iPhoto library (about 15000 images, circa 90 GB in size). I am trying to transfer the library from the iMac's hard drive to a 3TB Western Digital NAS drive (connected via Gigabit Ethernet) that I've just bought, and it's a nightmare.
I've tried a variety of different approaches - dragging and dropping the iPhoto Library package file onto the pictures directory of the new drive, just exporting the images contained in the 'Masters' subdirectory of the package file, and now using iPhoto Library Manager to attempt to pull the images from my current library into a new iPhoto library that I've created on the new drive. Each way seems to be incredibly lengthy - not just several hours, or even overnight (which I'm prepared for), but days and days - with the iPhoto Library Manager approach the import had been running for about 24 hours and was less than a third of the way through before iPhoto crashed and it stalled.
What is more, I also seem to be unable to delete any of the incomplete package files from the directory on the new drive - again, the progress bar just sits there reading 'Deleting 1 file' and doesn't really do anything. The new drive is formatted as Mac Share, and I can otherwise connect to it and browse through the various directories on there, save small files to it etc, without a problem.
What am I doing wrong? Many thanks for any suggestions.

Hi Terence, have read a few of your posts in similar threads this morning and am v relieved I did as I was definitely going to do this all wrong!
Having read your advice on referenced libraries, multiplie libraries, and NAS (ie all being bad) I have come up with the following planned approach for my situation but I would like to run it by you if thats ok?
I don't think I am particularly unusual in my scenario - I am an amateur user who has a personal photo lirbary from the last 10 years and expects it to grow pretty darn big in the future given we now seem to take 100 photos a month since having baby last year!
It already takes up 60GB (50%) of my SSD and so it has to go somewhere...the question is where...
However, where I think i may be less usual is that I don't really use events and additional tagging, I just like iPhoto as a viewer, organiser and slideshow.
From your advice to date I now understand that:
- I can't have my library on my NAS (had been plan 1!)
- Referenced libraries are strongly discouraged (plan 2)
- Using multiple lirbaries to split it down is also discouraged (plan 3, although less beneficial given none of them can go on NAS).
- I should use an ext local HD connected to my laptop when I need to access my photos. (should therefore be plan A but....)
The problem I have though is that using a local ext HD is the least appreciated option by my wife as she hates things being plugged into the laptop in the evening when she kidnaps the laptop for reading her forums, and will likely annoy me if I need to keep getting it from a cupboard, and can't stay in the living room with the little one roaming around and grabing everything gadget I own!
Plus, the most likely value in old photos is going to be that one unexepcted moment in the future when I want to bring one up to show a friend and I am away from the house....
SO, what I am thinking of doing is splitting the situation in 2:
- most of my organising, deleting, managing etc as well as obviously my importing, will happen within the first 6 months of taking a photo. Therefore I will have an iPhoto managed library for that. It will live on my local SSD and all will be good.
- and I will export all older photos to my NAS where they will the live from then on (and continue to move the 6 month expiry photos to this each month or two depending on size constraints). I will try and use events in iPhoto to organise everything before I do this, so that the folders will be useful and useable outside of iphoto on the NAS if I ever need to find anything to view.
- I will then re-import these photos into a second library in iPhoto so I keep the slideshow and viewing capabilities (not sure whether this needs to be a separate library, but probably makes things easier for me to see and manage).
If the links in this ever do get broken with iPhoto I am not sure this matters for me? - I could just re-import each folder and select the event name as the folder name. As mentioned, I don't tend to go into minute detail with events, so there won't be that many (ok, in 30 years time this may be more painful...but I imaging by then we will all be machines and there wil be a new way!)
And if I find I also want access to my <6month photos on NAS as well then I will keep a duplicate export of that on NAS (not managed as a libary within iPhoto) and continue to overwrite it with an export each 1-4 weeks depending on how I much I use things.
What do you think? Have you seen anyone take this approach, and can you see any obvious pitfalls from your experience that I am still missing?
Your advice is much appreciated,
cheers
Jon
A final point is that I have lots of photos from my pre-Mac days and these need to be brought together and consolidated into iPhoto and organised before I do my split. I was going to buy iphoto library manager as apprently it is good at finding the duplicates (I will have 1000's due to lazy copying discipline when i was younger) and I was going to use it for managing libraries anyway, but it is $30 and now I don't need all its functions I think I will just use a bespoke programme for finding any duplicates. I don't want to hijack the thread for this, but any recommendations would obviously be appreciated!

How do i move files from ipad to shared storage, how do i move files from ipad to shared storage

I have run out of room on my 64GB iPad. It contains two series of a TV program and I want to keep the episodes. However I would like to be able to get at these episodes wherever I am located be it in Australia, Europe or the USA so would like to have them located in shared storage. What is the best way to achieve this. I am somewhat confused with my choices and my last update experience of losing a number of movies makes me nervous. Any suggestions would be great. Thanks

All of your purchases are available free again from the stores. You can delete them and when you want to access them again just go to the store under purchased and select the ones you want. I do this all the time on my 16 gig ipad.

IPhoto sharing solution: NAS drive, cloud or...?

I'd like to share my 85GB iPhoto library wirelessly across a few different MacBooks without having to rely on the main computer being on all the time or even around. I've looked into adding the library to Google Drive or something similar as well as storing it on a NAS drive but can't decide which method would be best. My only other requirements are that it updates automatically from the main library.

No
Many reasons
1. The iPhoto library must be on a volume formatted Mac OS extended (journaled). I do not believe any NAS systems use that disk format
2. IPhoto is not a mulit user program so multiple users must only use it one at a time if they are editing or making any changes
3. Wireless connections are I'll advised for working with the iPhoto library. They are too unreliable and can corrupt your library
4. Your "only other requirement of automatic updates" is not available for iPhoto

File transfer speed in Shared USB Hard Drive via Airport Extreme

I' am planing to buy one of this, but first I need to know what kind of file transfer speed I can expect when sharing USB drive via Airport Extreme 1000Mbps Ethernet.
Thanks.

most likely 14m/sec but normally 10.5 this is ethernet wired and usb attached. wireless would be about 8M/sec
Wired is good enough I use it for Finder copy frequently.
