Permissions problem with external HD

Prior to updating to 10.4.3, I was able to write to any external HD to transfer large files betweek my iBook and a windows PC. After upgrading, I am no long able to use 3 out of the 4 external HDs that I used to be able to. I always get an error message stating a problem with permissions. I get info on the drive and it says read only and will not allow me to change to read and write. I plug the same drive into my Windows PC and change the permissions to read and write, and get the same message when I go back to my iBook, I get the same read only problem.
Any ideas?

Eric,
I, too, apologize for the delay in posting. I have been away from the discussions for a rather extended period.
Well, any NTFS formatted volume will only be accessible to you as read only. No, this is not something new, but has always been the case. To make matters worse, I have heard that Windows no longer provides any way to create a FAT-32 volume; one must use OS X to format the volume or use a third-party application in Windows. This information may be incorrect, but I wouldn't be surprised if it is true (we're talking about Microsoft, here).
If you can copy any data on this drive to some other location, then use Disk Utility to format it as FAT-32, the data can then be copied back and it can be used to transport the data cross-platform, with read/write access on both ends. Is this a possibility for you?

Permissions problem with External Hard drive.

Hi,
I've been using my external hard drive for almost a year now and out of the blue last night I ran into a interesting problem. For some reason I couldn't transfer any files to a thumb drive and shortly after I realized I didn't have Read and write permissions for any files on my mac, and everything required my password to get to. I went into disk utility and repaired the permissions and the list went on forever. Upon completion of that nothing was resolved.
SO! I popped in my Snow leopard disk and did a repair of the permissions and system through there hoping that would fix it. I than booted up the main drive and got stabbed in the face with a HUGE error message upon the apple loading screen with a "MISSING DRIVER" "KERNAL ERROR" "CORRUPT FILE" etc.
I went back and did a restore from my external harddrive hoping that would work, and it did. I can access my time machine backups from my external harddrive but cannot do so through my own control.
What should I do? Should I reformat my external harddrive? Which would suck because I'm a paranoid freak and if something would happen during the reformatting I will lose literally over a year of work that is crucial.

What is that, a "clone?" What do you mean by "cannot do so through my own control."?
What should I do? Should I reformat my external harddrive? Which would suck because I'm a paranoid freak and if something would happen during the reformatting I will lose literally over a year of work that is crucial.
Again, what's on that drive? Do you have a clone and TM backups on the same external? If so, are they in the same partition?

This one says you need to repair or reformat the disk; that means your backups are corrupted.
Try to do a +*Repair Disk+* (not permissions) on it.
If there are errors that Disk Utility can't fix, or the +*Repair Disk+* option is grayed out (meaning OSX has already determined that it can't fix it), post back.

Permissions problem with External Hardrive

Sorry to drag up this old topic, but I have a situation on a friends iMac that I cannot correct following the steps here.
It has an external drive connected that is data only, no MacOS. I have followed step #3 by typing the following chmod 775/Volumes/G-DRIVE/
I get a reply in the Terminal Window that shows:
usage: chmod [-fv] [-R [-H | -L | -P]] [-a | +a | =a [# [ n]]] mode |entry file... static-72-67-xxx-xxx :~accountname
(the x's represent the static I.P.)
but I still cannot see the drive.
Does this have to be done from the account that caused this issue, or can it be done with any account that has Admin privileges?
Sorry about dual posting. I picked up a thread that shows as solved earlier and can't delete my post there.

Thank you, it worked. I missed the space after 775.
He was trying to keep people from having access to the external drive when signed into that account.

Problems with external context mapping

Hi ,
I am having the following problems with external context mapping from one WD component to another.
Problem description:
In the <i>Component Interfaces</i> I have defined a WD interface "InfA".
In the <i>interface controller</i> of this compoenent,I have ContextA and attributeA(cardinality 1..1).The contextA is marked as an "Input Element".
Now my webdynpro componentB adds InfA as used component.In componentB I decalre a contextB with attributeB and map it to contextA to set up the external context mapping.
Now I expect that if any webdynpro component implements this WD interface InfA ,he has access to contextA with the data getting filled from contextB.
After i have created the component for the used component I try to fill values in the source node contextB thru this code:
wdContext.currentContextB.setB(value);
But in the runtime I keep getting error nullPointerException for nodeContextB,suggesting that the mapping has not been completed.
Can anyone suggest due to what the error can come ,and, if its a webdynpro bug ,is there a workaround??
Thanks in advance for your help.
Best regards
Sourav

HI,
Valery : I personally checked by doing the example, if the names of value attribute are different in the child's interface and parents component controller then it throws the exception.
Sourav: NullPointer Exception is thrown when something is not properly initialised, if in the main component the cardinality of mapped origin is 1.1 then you need to access it element directly like:
wdContext.currentParentNodeElement().setFname("Abhijeet");
wdContext.currentParentNodeElement().setLname("M");
i will suggest just check out if you are declaring some element of value node and without initialising taking its use or what?
if this doesnt solve your problem, please post the expanded exception.
hope it helps
let me know if you face nay problem
regards

Does anyone know what's missing?
Thanks in advance.
Best regards,

Hello Jason,
Thank you for your answer, but as I told, If I set an external breakpoint it does not stop for debugging, so I can't see table as you recomended. This process (debugging) is familiar to me, in last version I can do it.
Any suggestion?
Thanks in advance, best regards

I have a problem with external editing preferences where Photoshop will not launch when I choose "Edit In"...

Hi. I have a problem with external editing preferences. If I add Photoshop as an external editor, it won't launch when selected, if I add it as an additional external editor it will. Why? How can I fix this as I need to use Photoshop and another program as the additional external editor.
I use a Mac running OS X (10.8.5) and PS CS4 and LR 5.7. Any ideas on a fix? Thanks in advance.

I don't know why Photoshop won't start. However, it's possible to create external editor presets using the additional external editor tools. There are instructions on how to do this in the Lightroom help. You could assign Photoshop and create one preset, and then assign another program and create another preset.
I don't know if deleting your preferences would fix the problem or not. It can sometimes fix other problems.

Problem with External 2.1 digital speakers

Anybody have any problems with external digital speakers connected to the SPDIF connection? I have a 1215-600XT, and I tried connecting my old DELL Boston Acoustic 2.1 speakers. They worked, but any time a "sound" played, a loud pop would follow the end of the sound track. If its multiuple sounds (i.e. an application that is making numerous alert sounds) I get multiple pops. It even happens at the endf of music tracks. It was so annoying, I stopped using the speakers. before I invest in another set of speakers, want to know I am not wasting my time.
Also, anyway of getting the soundcard to support digital 2.1 or other sound? The set-up screen only shows stereo for external speakers and no way of adding more.
Sincerely
Scott

pmoney,
If you need a RMA, you will need to contact Customer Support either via email or phone. Also, it may be a fault with the sub and not just the cable alone, anyway contact Customer Support and they will be able to assist further.

Permissions and problems with external HDD

Starting today I have been unable to copy anything to my 1T Seagate FA GoFlex external HDD. I can access the drive, I can copy files FROM the drive back to my Mac Mini, but I cannot copy anything to the drive. Whenever I try to copy anything I get the error "The operation can’t be completed because an unexpected error occurred (error code -50)." I have spent the last four hours doing an exhaustive search, and have tried every solution I've come.
Somehow, over the last few days, something has happened to change this external HDD--the permissions and possibly the format. I have been in Disk Utility and am unable to repair. I have tried accessing Disk Utility from startup and am unable to repair. I have also copied the content off of the HDD and have tried to reformat the drive, but I'm getting an error when I try this as well.
When I tried to verify the disk I got this error:
When I tried to repair the disk I got this error:
After copying all of the important files to other drives, I attempted to reformat and got this error:
Then I tried the secure option and got this error:
I did notice that when I click on the Erase tab, the format shows as "Mac OS Extended" but when I click on the RAID tab the format shows "Mac OS Extended (Journaled)". Shouldn't these match?
I have been using this external HDD for several years now and have never had a problem. This does coincide with the copying of some .mp3 files. Could this be the culprit? (I was unable to remove one zip folder of these mp3 files.)
The permissions for this external HDD seem out of whack as well:
It states "You can only read" but the admin account "MiniMel (Me)" sholws Read & Write.
I am completely stumped and irritated. Is there any help for this HDD or is it just failing? It was no where near capacity. Could the mp3 files have caused the problem? I think this is unlikely, the the timing is coincidental. Should I worry about this happening to the other external HDD and my HD where I copied the files so I could reformat?
Any and all help is greatly appreciated.

Thank you for your reply.
I tried that last night. When I tried to verify the disk from startup, I received this message:
when I tried to repair the disk I received this message:
After the second message, I moved what I needed off the external HDD and tried to reformat. Which led to the errors in my OP. So frustrating.

10.5.7 update results in major problem with external drives

yesterday I did the 10.5.7 update and now I can't access any of my external hard drives. The message is "you do not have proper privileges". Have tried downloading/installing the combo update, running permissions repair with Disk Utility, even tried reinstalling my original 10.5.2 system with 'Archive and Install', still the problem persists.
In the privileges dialog, the setting is 'custom' and I can't switch anything back to "read/write".
I'm sure there are other problems but this is quite major as all my work files are located in external drives.
help!

Is it only Lacie drives you've had trouble with, or is it other brands as well?
This is probably a separate problem, but when I updated to OS X 10.5.7, my Buffalo hard drives disappeared. See these threads:

Permissions problem with Battery 2

This is the story so far....
When trying to install a music application,(Battery 2 to use as a plug-in inside Logic 6) an error message appears: "You do not have sufficent access privaleges for this installation". After much forum seraches the general advice is that i should fix permissions in disk utility...However,
In disk utility the fix permissions tab is consantly greyed out and so i cant do this.
I have two hardrives, one that came instaled with my mac, and which i use for my applications and to where i am trying to install Battery 2, and one HD that i use for Audio only that i installed. I can fix permissions for the Audio only hardrive, as the tab is not greyed out.
What is going on?
People have suggested that this may be related to why i cannot install my Battery 2 software.
I have never had a problem installing any software though!
John

Not sure I understand your question about the placement of the library. I've always understood that the "library" is the files located in the Music Folder. Anyway...glad you got it working. I was thinking that if you had your songs stored on a different drive -- not on your hard drive -- that perhaps somehow permissions for the external drive had gotten messed up. Again...glad it's working now.

Error code 36 (problems with external hard drive)

I have just upgraded to Yosemite and am now having major problem with my external western digital hard drive. I cannot create new folders and when I hit command N I get error code 36. I also cannot move files from one folder to the next. When I try to move them I get the error message: "The operation cannot be completed because a file of that name already exists" and that simply isn't true. None of the files' names exist in the other folder.

Ok, It appears to be the fault of Western Digital. I ejected the hard drive and then plugged it back in and it said that the drive was broken but I could still read the files and it told me to save the files on another disk and reformat. So it was just a coincidence that I upgraded to Yosemite at the same time that my external hard drive broke.

Disk Permissions Problem on External HD Accessed Wirelessly

Hello,
I recently purchased a LaCinema Connect MiniHD and have been using it with a Western Digital 750Gb drive (formatted Mac OS Case Sensitive, non-journaled). I also recently bought a D-Link DWA-125 wifi dongle to use with the LaCinema.
I can access and read/write to the drive without problem when it connected via USB to my computer or to my wife's laptop. However, when I try to trasnfer to it wirelessly over the network (i.e. when the drive is connected to the LaCinema which, in turn, is on the network) I receive error messages when I attempt to transfer files to certain folders (including the "root" folder). What is interesting is that the folders that I can transfer to appear to be ones that were created on my old work computer, with an earlier OS version (definitely not Snow Leopard).
I suspect that I have some sort of permissions problem, but "Repair Permissions" is not available to me for this drive in Disk Utility.
I have plugged in the drive into my computer and have reset the permissions so that the "owner", "staff", and "everyone" are able to read and write for all folders and sub-folders, but it has not solved the problem.
Any advice would be greatly appreciated.
Thanks,
Graeme.

Problems with External Monitor In XP

Ok, I've got a huge problem with XP on Bootcamp.
I've recently got a Samsung TV which I can use as an external monitor. This works absolutely fine when I'm using OSX, recognizes the TV and can use it as a second screen.
When I try to use the same monitor in Windows under Bootcamp, it works as an extension of my desktop, but not able to mirror my desktop. I want to do this so I can play my games on a large screen instead of a small one.
I've trawled the forums on this kind of problem and found a few answers. However, many of them talk about the ATI graphics drivers. I've downloaded the appropriate drivers and the control center from the website, but to no avail.
People have also said about going into display properties: settings: advanced and selecting the ATI tab. I have no ATI tab.
Also with the Catalyst Control Center, when I try to run it, it tells me that I dont have permission to change the settings and to contact my administrator, even though I am the administrator.
Does anyone have any ideas how I can solve this?
By the way. I'm connecting the external monitor via the DVI on my Macbook Pro to the HDMI connection on the TV.
Many thanks
Chris

My logic tells me, if you are using a new MBP the way it's designed is that even if you are plugged in at times it will go in battery mode for a few minutes in order to prevent battery damage, than it will recharge. This happens in the background without notice. However, within this couple of minutes you might notice your display screen to sleep because it is setup to sleep in 1 minute or less in the preference under battery mode. So within that window you might have your screen go blank since the entire process takes a lot more than a minute. I hope this helps.

Inkscape/X11 Problems with external Monitor

Hello,
I´m using Inkscape to create vector art on my MacBook Pro.
Since my update to Mavericks I´m having problems with X11. I have the version 2.7.5 of XQuartz installed currently.
After some troubles, Inkscape opens up just fine.
But I cannot drag Inkscape over to my external monitor, which is based to the right of my notebook.
Inkscape simply disappears.
I´m quite the DAU ;-) with Computers and Software, so it would be nice, if you can help me.
Thanks a lot in advance!

Configuration problem with external Western Digital My Book 2 TB drive

How do I fix a configuration problem with my external Western Digital My Book 2 TB drive which used to both read and write. Something has happened so that the drive is now read only? There is 600 GB of data on the drive that I cannot lose, thus am very concerned about messing around with formatting the drive which is raid 1 and filled with data.

may not like to hear, but I'd skip on MyBook cases, nice looking as they are.
Get a 2nd drive case to recover to.
http://www.macsales.com/firewire
may need to play with the demo Data Rescue 3 from Prosoft
Backup/recover before repair is usually in order
never have one backup set. THREE sets of your data, minimum.
3rd party disk maintenance and repair should be a must and given rather than rely solely on Apple Disk Utility.
Data and system maintenance and recovery plan - should be like practice for sports, arts, military with practice and making sure you will know how and the tools you need - ahead of time
Resetting USB/FW ports, try another if one won't work. When 10.6 came out there was a lot of grinding teeth with external drives not working or mounting.
