Permissions problem - unable to write to external drive

I have 2 x 2TB external drives connected to which I have been manually copying media from other drives with mixed content.
The same content has been copied to both from other drives of mixed content - drives 1 and 2 are manual copies of each other.
I have set both to ignore ownership on Lion but cannot write to drive 1 but I can to drive 2.
Under Snow Leopard both are writable. Ignore ownership is not appearing checked though.
Looks as though I created my user accounts out of order for the new Mountain Lion boot drive - under SL the user UID is 503, for ML 502. Same group.
Any suggestions about how to rectify?
Not a huge issue as they're nearly full and I can complete this via Snow Leopard as they will be effectively read only archives when full.
Any advise on how you would approach this?
The problem may partly stem from using several non admin accounts for different purposes but I can't see why ML is making one disk read only.

Thanks Linc
That's what's slightly odd.
As far as I can remember I used disk utility to create these external volumes via Snow Leopard and it's on ML they are showing with Ignore ownership - I can't remember if I ever set that manually as I upgraded a Lion boot disk I'd rarely used on a Mac Pro.
Found this earlier and not sure if it is relevant as it's the same Mac Pro:

Unable to write to external drive after drive sleeps

This topic seems to be all over the place. I want to know if there is a fix.
I have a number of external disk drives. They are connected via USB and firewire. About 30% of the time, if a drive has been put in sleep mode and then later awakened, I am unable to write to it. If I try to dismount the drive I get a -50 error that the drive is in use. But that is not true because nothing but the finder is running. If I look the console log there are lots of the following messages.
Dec 6 15:50:43 squid fseventsd[45]: disk logger: failed to open output file /Volumes/Calvary1TB/.fseventsd/63657332a56b8d30 (Invalid argument). mount point /Volumes/Calvary1TB/.fseventsd
Dec 6 15:50:50 squid UnmountAssistant[1463]:
The drive in question is the CAXM Calvary1TB drive. BTW when I received the Calvary disk drive, I reformatted it OSX journaled with a GUID partition before using it. All my other 8 TB of storage is formatted the same way and I had no problems before Snow Leopard. Anyhow, If I force a dismount, all returns to normal. OR if I disable sleep the drive drives options in the energy saver preferences, the problem disappears. But then none of the drives ever spin down.
Once every 50 or so forced dismounts (it happens a lot), OSX will crash with the kiss of death display.
This problem did not exist in pre Snow Leopard, so obviously changes were made to the file system and not properly tested. Anyone have any idea when this will be fixed.

The drive in question is the CAXM Calvary1TB drive.
Calvary lists this drive series only in its "Windows PC" section at http://www.cavalrystorage.com/pr_index.htm. This could be a problem because different manufacturers use different methods to implement wake-from-sleep (or more generally, energy management features) in the support circuitry of external drives. IOW, there are no universal standards for this, so manufacturers may or may not design their implementations for cross-platform compatibility.
Unfortunately, since Windows PC's dominate the market some manufacturers use energy management methods in some or all of their designs that work reliably only with that platform. For this reason, there is always some risk of unexpected behavior when using external drives not specifically marketed as Mac OS X compatible with a Mac. (This is not a problem with "raw" internal drives directly connected to a Mac's SATA interface because there is no support circuitry involved.)
Since you already have invested in these drives, your best bet is to contact Calvary & see if they can offer a solution. If you are lucky, they may have a firmware updater for the CAXM series that works reliably with Snow Leopard; if not, they may simply tell you not to let the drives sleep, or that they don't support the CAXM series with Macs & you are on your own.

Mac Mini (Mid 2010) Unable to write to external HD

Hey All,
     I have a Mid 2010 Mac Mini that becomes unable to write to a drive after an extended period of the drive being connected. HD is an external HD with it's own power supply connected of USB. Both iTunes (Using the drive to store Library) and Finder fail to write to the drive with error (-50) after around 10 hours. Tested multiple times, unmount and re-mounting drive temporarily fixes issue.
Trouble shooting so far:
     • HD has been replaced.
     • Mac Mini has been re-imaged multiple times. Tried server 10.7.2 and client 10.7.2
     • Multiple USB ports have been tested.
Thoughts? Drive is a 2TB LaCie Porsche Design.
Thanks in advanced,
Tim.

If you use Parallels then you will need at least 4 GBs of RAM. Otherwise, what makes you believe you need more RAM? What typical RAM usage do you observe using Activity Monitor? Also, see:
About OS X Memory Management and Usage
Reading system memory usage in Activity Monitor
Memory Management in Mac OS X
Performance Guidelines- Memory Management in Mac OS X
A detailed look at memory usage in OS X
Understanding top output in the Terminal
The amount of available RAM for applications is the sum of Free RAM and Inactive RAM. This will change as applications are opened and closed or change from active to inactive status. The Swap figure represents an estimate of the total amount of swap space required for VM if used, but does not necessarily indicate the actual size of the existing swap file. If you are really in need of more RAM that would be indicated by how frequently the system uses VM. If you open the Terminal and run the top command at the prompt you will find information reported on Pageins () and Pageouts (). Pageouts () is the important figure. If the value in the parentheses is 0 (zero) then OS X is not making instantaneous use of VM which means you have adequate physical RAM for the system with the applications you have loaded. If the figure in parentheses is running positive and your hard drive is constantly being used (thrashing) then you need more physical RAM.
Adding RAM only makes it possible to run more programs concurrently. It doesn't speed up the computer nor make games run faster. What it can do is prevent the system from having to use disk-based VM when it runs out of RAM because you are trying to run too many applications concurrently or using applications that are extremely RAM dependent. It will improve the performance of applications that run mostly in RAM or when loading programs.

Serious problems after Mavericks installation with External Drive Lacie P9220.

Experiencing serious problems after Mavericks installation with External Drive Lacie P9220 1TB. Mac Finder totally locked!
I had to format the External hard drive with a Windows PC (fat32), then format again with my IMac (mac Journal.) and hopefully restored data from time machine backup.
So far so good but system looks unstable. Some software were not able to write on the hard drive.Some strange things happens. With Mountain Lion never had an even minor issue.
I read many discussion regarding problems with WD, just wondering if anyone had the same problems with Lacie and if there is any tip to solve the
problem.
Many thanks.
Marco

Thanks very much for your reply.
Unfortunately I couldn't find a solution because the article refers to whom have configured the drive with included software and drivers that came with the drive.
This is not my case, I never used any third party soft ...only OS X disk utility ...

Permission Problems After Clean Intall Accessing External Drives

Okay, the ubiquitous permissions problem. Perhaps apple should release a system update that strips this BS out, as single users and home users, do we really need this? I'm just driving my Ferrari to the grocery store! It is just complications that nobody needs.
So, with a fat chance of that happening, is there a DEFINITIVE paper/instruction on permissions? Please point me to it. I've tried here and there is nothing that seems to work for me. I'd like to NOT have to learn anything and continue without messing around with this crap, but it did it to me, so now I'm forced to screw around to fix it.
(I used to be a system admin years ago so I can take a fairly technical approach, but I'd rather not. (Puh-leeze! No terminal instructions.)
Here's my problem:
Having had a problem with corrupt login items and being unable to uninstall them, (the machine crashed and rebooted) I was left to perform a clean install of my system.
I have numerous hard drives attached.
Well, upon a successful install and migration of settings from Safari and Firefox and such, I was gently told that a couple of my drives are not accessible by me, the user. (I can see'em, but some apps like transmission won't write to them. Or backup software cannot backup to them.) I'm currently setup up with my daily account/user as the admin, with the super-admin account dormant and not used, as I've been instructed. (My previous system had me using my super-admin account all the time.)
How do I go about setting permissions to reaccess these drives without checking the "ignore permissions" box?
Is the simplist thing to do, to just copy/backup the drives, erase them under my present account, and re-install the data to fix this permission BS?
I've done the "fix permissions" thing and it does not help.
Do drives that you create with a former system user, retain the user profile that created them even after you install a new system, thus causing this problem?
Thanks
Herkimer

What users do you have defined on your system?
Herkime wrote:
Thanks for the help, guys. I downloaded the app and will take a look at that to fix my problems.
What user do you want to use to look at the data?
Decide what user you are going to logon as.
Use BatChmod to make this the owner of the data. The group should be whatever is the group assigned to your logon user.
Do drives that you create with a former system user, retain the user profile that created them even after you install a new system, thus causing this problem?
Files you created with root still have root permissions.
The other 5 diskes, internal, externals FW, and removeables FW toasters, were all created under the old system, using the super-admin user. That designation is gone. (Actually, I recreated the same name/login on the newly installed system, along with my everyday admin user log in.
I get the feeling I'm stuck in a little permission limbo, as the disks are looking for the old super-user and that's gone. Correct?
I assume by super-user you mean root. You can enable the root account again if you wish. There is not need.
I'm not sure what user, or group I should be setting everything too, now. Me, as the admin/user or
Who is Herk the super-admin? How did you define Herk.
By definition super-user is root. You are not allowed to rename root. So the super user isn't Herk.
A user can be given admin rights. This doesn't give the user super user/root rights. Root can read & write any file on the system. This root is the super user.
By Herk do you mine you gave Herk admin rights?
Bottom line:
[] Decide what user you will be using on your system.
[] Change all permission you your external drives to match user & group of that id.
Some people define two user on their system. This way maybe more secure, but with more hassles.
standard user
admin user
I run with one user:
admin user. This lets me install programs without have to change to another user. It doesn't let me look at system data. I cannot look at other userids data. ( I want to look at data I do not have permissions to, I can use the terminal to gain access. )

Aperture can't write to external drive? Up with what is that?

Hi. I keep getting the following notice:
I have re-booted, repaired permission and disk on both the disk and the partition, and repaired permissions and the Aperture Library. Each time I repair the Library I can process about 90% of the selected files, but that is all. Then re-repair, then do another 90%.
All software up-to-date. The external drive is one of several USB-3 drives I use, via one of two USB-3 hubs. I have never had any problems with any of these drives or hubs. The drive in question has been used continuously for Originals for months.
Any advice? Drive going south? Gremlins arm-wrestling to prepare for Mavericks?
Thanks .

O.K., a short answer. Kirby may not like it to have his trouble shooting thread hijacked:
I want to keep the originals on my machine as well.
Don't worry, exporting images will only write new copies of your images to the designated export folder - originals and versions will stay unchanged in Aperture.
Can you tell me if there is any difference in exporting originals as opposed to exporting versions? You had suggested I export versions.
When you export a version, you will get an image file, that includes all your adjustments. And you can chose from different export presets to determin the size and quality of the exported version.
Exporting the original will give you an exact copy of the file you originally imported.

Problem copying files between two external drives...

Hello, and thanks for any ideas on this one.
I have a punch of .m4v video files on a 1TB Lacie external drive, but re cently bought two 3TB Seagate drives and wanted to move all these media files over to one of the new drives. Most of the .m4v files moved just fine, but I encountered two different issues in the process that I can't resolve.
I'm on an Intel-based iMac (Core 2 Duo), running OSX 10.5.8.
1. Most pressing problem:
One of the video files, when I try to copy, causes the finder windows to completely freeze requiring a hard reboot of the machine to fix. I can get infomation on the file OK, and can play it off the original drive just fine, but try and copy it and all manners of computer death take place. There does not seem to be a permissions issue, and the file isn't flagged as locked.
This command produces no fruit either: $ lsof | grep videofile.m4v
2. Second issue:
This one affects two other files. When trying to move them over, they get approx half way there and then I get a notice that the operation cannot be completed because the files are supposedly in use.
All the googling I can do on that error seems to bring up cases where files can't even start to be moved... but in these two files, they get half there. Or maybe they're read OK but then can't write? Either way the status bars show about 1 GIG or 1.7 copied. I don't know.
I also checked the permissions, the locked setting, used the lsof command, etc... no luck.
About 100 other videos copied over just fine.
Any ideas are greatly appreciated.

Thanks for the response... I tried just now, no luck.
I did at least get an error this time for problem one above before the lock up... lol... error code 36. So far searching for that isn't coming up with any solutions either.

Hi Sybrand,
I just wish to please check below:
1.As Aman suggested to deinstall anti-virus program
2.free space on external hard disk
3.Path and Permission issue (if any)
4.May be filesystem of the external drive issue
5.May be issue of filesystem size limit.
5(i).FAT32 is 4GB and NTFS is 16 exabytes. FAT16 (mainly DOS) was 2GB, but some instances supported 4GB. A windows server class machine is almost 100% going to be using NTFS. Same issue on SQL Server with a local account trying to do things on an NFS. Use a domain account/NTFS.

Problems using iTunes and my external drive.

So I initially had a little trouble getting my iTunes to work smoothly with my external drive, a My Book 1Tb, but after a lot of trouble shooting and help from people on the forum I got it and it worked brilliantly. But now, it seems to have run out of gas, the drive is on (indicated by the blue light on the front of the case) but there is no disk image on my desktop and no matter how many time I 1) search for the drive, 2) disconnect it physically from the computer and reconnect it, 3) shut everything down and boot back up it is still unresponsive. I started having problems with my TimeMachine saying it could not back up files onto the disk and couldn't figure that problem out either. And now this, I am really hoping it isn't the drive, even though I thought it was. However, my Mac (iMac G5) has really been acting up now too.
Every time I try to verify and repair the disk permissions in DiskUtility it freezes while still verifying. And my iTunes has been locking up and constantly unresponsive. I am not that savy with technology and so I am now at the end of my rope.
Please help me solve my issues?

You might want to take this over to the Leopard discussion group since it really sounds like it is a drive or computer issue. It will get better attention that way.

Problem with Shift to New External Drive for iTunes

Hi,
I hope I can explain this clearly. I currently have all my music files on an external drive however the iTunes Library files, xml, etc are on my laptop. The external drive is running out of space so I simply got another external put the same exact music files on there but am having trouble getting iTunes to read from this new location. Is there a way to simply get the computer to read from this new file WITHOUT copying all the files over via changing the Media Folder Location and using the Library>Organize Library>Consolidate function? That seems ridiculous when I already have the files on the external drive and I'm worried that they will somehow be altered in the copying process.
I also like to have my iTunes Library files on my hard drive but is it better to have them with the music on the external drive?
I hope that makes sense and thanks in advance for the help, I simply couldn't find anything on here that quite describes that problem.

OK, not having a Mac I keep forgeting details. See this support document for how to use Option to open an alternate library.
Can I just confirm that you've already copied your existing media from External/Music/iTunes to
New?External/Music/iTunes without changing the layout of any of the subfolders inside. If so then we should be good to go. While there are quite a few steps the aim is to avoid recopying any files that are already where they need to be and make sure that your playlists, playcounts and other meta-data remains intact.
1. Copy the *Album Artwork* folder and the files *iTunes Library, iTunes Library Extras.itdb, iTunes Library Genius.itdb & sentinel* from <User>/Music/iTunes/ to External/Music/. Ignore the XML file, it would get a new name in this location and will be recreated automatically.
2. Start iTunes, pressing Option until prompted to choose or create a libray. Chose the library at External/Music/.
3. Check that the media plays. Check under *Edit > Preferences > Advanced* that the location of the media folder reads as External/Music/iTunes.
4. Close iTunes.
5. Copy the *Album Artwork* folder and the files *iTunes Library, iTunes Library Extras.itdb, iTunes Library Genius.itdb & sentinel* from External/Music/ to New?External/Music/. Again, ignore the XML file.
6. Use Option-Start iTunes to open the new library at New?External/Music/.
7. Check that the media plays and that under *Edit > Preferences > Advanced* that the location of the media folder now reads as New?External/Music/iTunes/.
8. Close iTunes, rename the folder New?External/Music/iTunes/ as *New?External/Music/iTunes Media/*.
9. Start iTunes. Check that the media plays and that under *Edit > Preferences > Advanced* that the location of the media folder now reads as *New?External/Music/iTunes Media*.
10. Close iTunes, rename the folder New?External/Music/ as New?External/iTunes/.
11. Use Option-Start iTunes to open the library at New?External/iTunes/.
12. Check that the media plays and that under *Edit > Preferences > Advanced* that the location of the media folder now reads as *New?External/iTunes/iTunes Media/*.
13. You should now be able to use *File > Library > Organize Library... > Consolidate files* to consolidate any files left behind in *<User>/Music/iTunes/iTunes Music/* that you weren't able to consolidate to your old external drive.
14. If you haven't already done so then you should also select the option *File > Library > Organize Library... > Re-organize files in the folder "iTunes Media"*. If the option is greyed out then you have already upgraded to "iTunes Media Organization".
15. Rename the folder <User>/Music/iTunes/ as *<User>/Music/Old iTunes/*. Now if you ever start iTunes without connecting the external first iTunes will complain that it can't find the library instead of silently switching to the old internal one. This is likely to lead to less confusion in the long run.
16. Backup... You should get another drive big enough to hold everything so you have a backup copy for disaster recovery. Now that everything is organisized sensibly you just need to copy the iTunes folder from one external drive to another to back it up or better yet locate a folder syncing tool so that only new & changed files need to be copied across when you back up.

Problems moving library from old external drive to new one

I keep all my music on an external hard drive connected to my laptop at home. I am now spending several months away from home, and couldn't take my external drive with me.
I planned to handle this by using iTunes backup feature to put my whole library on DVD, then buy a new external hard drive to take with me, and sse iTunes backup feature to rebuild the library on the new external HDD.
However, I can't get the library to restore/re-load/re-import from the backup DVDs. The iTunes backup/restore instructions tell you to open iTunes then insert the backup DVD. When I do that, I get the following error message:
"The Disc "Backup2007-07-09" cannot be read. An unknown error occurred (-69)."
However, I can read the DVD using just going through My Computer, so I really don't believe it's a problem with the disc.
So, if this backup method isn't working, how can I re-create my library on the new hard drive? I have dozens and dozens of playlists, a lot of them smart playlists that depend on such things as play count, rating, and date added, so i really need to keep all my tags.
I thought of two possible work-arounds.
Plan A: Copy all the music myself (ie, not using iTunes) onto the new external hard drive, using the same filename and path as they had on the old external hard drive, then import the Library.itl file that's on the backup DVD (manually copying over the default one created by iTunes).
Would that work? The big annoyance of this plan, I should add, is that, looking at the files on the backup DVD, i can see that iTunes added a number behind each folder name (ie, "01 Al Green") and behind each album title (ie, "01 Al Green - Greatest Hits"). It seems to me I would have to go through and manually delete all the numerals in both artist and album names in order for the .itl file to point to the right place. That would take hours...
Plan B: (Really not a great plan, but I'm grasping here...)
Give up on the backup altogether. Keep adding music and podcasts to my library as is. All my music that is sitting on my far, far away home HDD will get the exclamation point next to it in iTunes. Then, when i try to sync the ipod, if i'm thinking this through right, iTunes will go ahead and add the new stuff to my ipod, but all the old stuff will just not copy over, and then at the end of syncing i'll get the error message to the effect of "itunes didn't copy song x because the file could not be found." This option is far from ideal, as my playlists won't update, but at least i'll still have the playlists.
Do either of these sound like they would work?
Any other suggestions?
Any help would be very much appreciated.

If you can you connect both external drives to the computer at the same time, it would be easier to use the "Consolidate Library" utility in iTunes to move (actually copy) your media to the new drive.
1- Open iTunes preferences and select the Advanced tab. Change the location of your iTunes music folder to a location on your new drive. Also select the options "Keep iTunes music folder organized" and "Copy files to iTunes music folder when adding to library". Close the preferences dialog.
2- On the iTunes menu, select Advanced/Consolidate Library. This will gather all your media and copy it to the new location (the folder you designated in step 1).
3- After the consolidation is complete, verify that your music still plays, and check "Get Info" on some items to verify that iTunes is looking at the new location.
4- Optional. Delete the original files on your external drive. Do this only if you are certain that everything copied over to the new drive.
5- Optional. Close iTunes and locate your "iTunes Library.itl" file. This is typically in your iTunes folder, which may be on your computer's drive and not the external drive. Move this file to somewhere on your new external drive. Next, hold the Shift key as you launch iTunes and you'll be prompted to "Create Library" or "Choose Library". Select "Choose Library" and navigate to where you put the "iTunes Library.itl" file. This is a one-time step that tells iTunes where to boot the library from.

Problems playing iTunes purchases from external drive on new computer.

My computer recently died and I had to get a new one. Luckily I had copied all of my iTunes purchases onto an external drive. However, when I connect the external drive to the new computer I can see the purchases but cannot see them in iTunes-I try adding the files in iTunes, but this doesn't work. I have authorised the computer, so it should be able to play the purchases but I have tried dragging them all into iTunes, copying them to the computer but no joy.
Any help would be appreciated.

In Windows Explorer, right-click on your media folder and click Properties, then go to the Security tab and click Advanced. If necessary grant your account and SYSTEM full control of this folder, subfolders and files, then tick the option to replace permissions on child objects which will repair permissions throughout the library. This is the XP dialog but Windows 7 shouldn't be too different.
If it won't let you change the permissions use the Owner tab to take ownneship from an account with administror privileges.

Having problems connecting my iTunes to external drive

I am migrating from a PC to iMac. My itunes on my PC connects to an external drive which was entered into the "itunes media folder location" under Advannced.
I am trying to connect to this drive on my Mac and I am getting the message " There was a proble connecting to the server "Music" The version of the server you ar trying to connect to is not supported. Please contact your system administrator to resolve the problem"
I have installed itunes via Parallel and connected no problem to the 'music' drive. Sort of seem to defeat the point of having two versions of itunes running. Is there something i need to do got it working on the Mac op system?
thanks

I don't know why you are installing iTunes through Parallels since Mac has its own version of iTunes.
The get iTunes for Mac to use iTunes on the external, hold down the option key while starting iTunes and guide it to the library file in the iTunes folder on the external drive. If it says it cannot find a library file then that means you don't have a complete set of files on the external to get it to be used in this way and will need to reconfigure your library.
Another issue you may encounter is drive format incompatibility. If you formatted this drive with a Windows computer it will likely be NTFS formatted. You will either need to wipe the drive and reformat to FAT32 for use with both Macs and PCs, or the Mac format. Depending upon which way you want to go you will need third party software.
I've omitted a lot of details, but we can provide those once we know exactly how you want to operate.

If you restore the iPod you will delete the files, so don't do it unless you have backups. Sorry I don't know about the error code.
