USB Hard Drive Permissions Issue

Hi,
I just attached a new USB hard drive to my iMac. I would like to make it so only I can have write access to the drive; I want my kids to be able to see the files but not modify or delete.
I tried by unchecking 'Ignore permissions', and setting permissions where I have read/write, and others have read, but when I switch to one of my kids' accounts, they have full control, and in fact they are shown as owner.
Thanks for any help you can provide,
Andy

Hello Asopos,
I have difficulty in reading the screenshots, you can post in the corresponding forum or add some comments.

If my understanding is right, in the USB-hard-drive(NTFS), all folders in the USB drive have the unknown account and the root of the drive don’t have the account.
It is a SID. Possible that this account was removed and permission has not been removed.
Please take ownership of the folder and check if we can normally deleted the account.

USB Hard drive, permission issue on one partition

Hi,
I have an issue with my USB hard drive, when I pluged it the 3 partitions are mounted, and 2 of them grant access to the users group:
mount
/dev/sdc6 on /media/usbhd-sdc6 type ext2 (rw,relatime)
/dev/sdc1 on /media/usbhd-sdc1 type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096,default_permissions)
/dev/sdc5 on /media/usbhd-sdc5 type vfat (rw,relatime,utf8,gid=100,umask=002)
ls -l /media/
drwxrwxr-x 1 root users 4096 Jun 29 22:21 usbhd-sdc1
drwxrwxr-x 18 root users 16384 Dec 31 1969 usbhd-sdc5
drwxr-xr-x 3 root root 4096 Jun 29 22:21 usbhd-sdc6
I read the wiki page about udev, but I can not solve this issue.
PS : HAL is removed from my daemons list.

> You can write on "usb" because the right are : drwxrwxrwx
They appear only when I use 'sudo mount -o rw,noauto,async,user,umask=1000' instead of plain 'sudo mount /dev/sdb1 /mnt/usb2'.
I use vfat for that USB stick, so maybe that's why it works for me. The first two listings in your first post show the drives in different order, but of course the mountpoints show that the offending drive is ext2 not vfat, my bad.
Edit: This is how my ext3 USB stick behaves like:
[karol@black test]$ sudo mount /dev/sdb1 /mnt/usb
[karol@black test]$ mount | grep sdb1
/dev/sdb1 on /mnt/usb type ext3 (rw)
[karol@black test]$ ls -l /mnt
total 8
drwxr-xr-x 2 karol users 4096 07-03 01:08 usb
drwxr-xr-x 2 root root 4096 2009-09-14 usb2
This time /mnt/usb is an ext3. As you can see, there's no root, I (karol) an the owner, so I can rw to my heart's content. Maybe you should change the ownership - 'chown' (man chown if you're not familiar w/ that command).

Airport extreme with USB hard drive permissions problem may be parallels

I cannot access my external hard drive because of some permission problem. I know because I can see this through the disk repair utility. I've attached my external hard drive to my airport extreme. It originally came up well and worked fine. Then it lost connection and now doesn't recognize my password. To confuse matters worse I have parallels installed. This might be where the password problem is as the mac wants to access as a guest and the parallels (windows MX) as my account name. It's all pretty complicated to explain. What I want to do now is just to forget the airport plan and reach my hard drive but it won't boot up even with airport off and a direct firewire connection. It does show up in disk repair utility but with permissions. How can I get to these permissions and drop them. What if they're windows permissions somehow? How can I get started.
Thanks

I have a very similar problem. I have a 2.8 GHz iMac with 2GB RAM and am using OS X v10.5.4, and an Airport Extreme (v7.3.2), both updated to latest firmware. I have a 500 GB TrekStor external HD connected to the AEBS via USB. The TrekStor HD was pre-formatted in FAT32 and is visible on my iMac's desktop and in Finder but I cannot transfer files to it or see files on it. When I drag and drop a file on the TrekStor, it sometimes seems to go well but then the file is not visible via Finder, and sometimes I get an "insufficient privileges" message. I repair permissions on the iMac's internal HD without any change. I am logged in as the admin. All assistance is much appreciated!

Spotlight not finding files on my Hard Drive - permissions issue?

I found that Spotlight in Mountain Lion was often not finding files when searching for words within the file (searching file names seemed to be OK).
I found various threads suggesting that it may be a problem with File Permissions. I use Dropbox and was concerned it may have messed up permissions after a relinking a while ago.
I tried to reset permissions from within Dropbox (under Settings, as suggested by some), but no help.
Finally I found this EXCELLENT TIP to reset permissions from within the Repair Utility (in Mountain Lion), Not the Disk Utility, which I had not been aware of:https://discussions.apple.com/message/20421138#20421138
It took a little while and then Spotlight re-indexed all my files. SO FAR it seems to be working well.
THANK YOU!!

Might try this...
Safe Boot , (holding Shift key down at bootup), use Disk Utility from there to Repair Permissions, test if things work OK in Safe Mode.
Then move these files to the Desktop for now...
/Users/YourUserName/Library/Preferences/com.apple.finder.plist
/Users/YourUserName/Library/Preferences/com.apple.systempreferences.plist
/Users/YourUserName/Library/Preferences/com.apple.desktop.plist
/Users/YourUserName/Library/Preferences/com.apple.recentitems.plist
Reboot & test.
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.

Airport Extreme Shared USB Hard Drive Performance Issues

I just picked up a new Air Extreme and attached a new Western Digital Passport via USB powered hub (have printer as well). All is working well, however, I am finding performance (especially copying files from my computer to the network HD) to be quite slow. For example, I was trying to copy a 3GB folder with about 1000 files and the copy dialog indicates that it will take about 30 hours. I was able to copy directly to the HD when plugged into computer's USB in a matter of minutes. When I try to download same folder from the net drive to my laptop, it takes about 1 hour. Note: I have Comcast Cable hi-speed so not sure how much is related to this knowing that they do have different download/upload speeds.
I would appreciate any feedback, tips and advice on optimizing performance of my USB drive when shared over the network. Thanks.

How do you have your hard drive formatted? If you are using a Western Digital Passport, you will want to create a separate Mac partition so that you can copy very large files (+4GB). By default, I believe it is FAT32. I had to do this (Mac partition) with my back up drive because I have VMWare Fusion images that easily exceed this.
The new network drive I attached is also a Western Digital, but I didn't reformat it (yet) as I knew I wasn't going to have large files, but I am wondering if maybe I should do this. Unfortunately, then my Windows machines would not be able to read it easily.

Changing permissions on external usb hard drive

This is similar to the other thread about USB hard drive permissions, but I didn't want to hijack.
I just got the USB drive working, as root I can read and write to it.
As user it still automounts, but I don't have read write permissions. Here's some output:
[ali@misbarch ~]$ cd /media/disk
[ali@misbarch disk]$ ls -l
total 16
drwx------ 2 root root 16384 2008-05-08 01:14 lost+found
The permissions tab in properties of /disk show:
Owner: root (root)
Access: Read & Write
Group: root
Access: Read only
Others: Read only
So I want to change "Others" to read and write also. I'm not very good with the chmod numbers, I've read the man page, but is that how I would do this? Would a simple
chmod 777 -R /media/disk
be advisable? Or is that just a bad work around and not the proper solution?
Once I got it readable, I copied the info off it as root, and I unmounted it, deleted the partition, created the partition, made an ext3 file system, all as root. Does that have anything to do with it?

There is a slightly better solution: change the group of /media/disk to storage, change permissions to 775 and add users that need to be able to write to disk to the storage group (you need to log out and log in that users before changes are visible).
So, as root:
# chgrp storage /media/disk
# chmod 775 /media/disk
# gpasswd -a user_name storage
This way everyone will be able to read the disk, but only root and users in storage group will be able to write to it. Still, if you want everyone to be able to read/write, chmod 777 is a good solution.
Nice solution, thanks, I'm already added to the group storage, but media/disk wasn't part of storage, it was part of root! Thanks for the solution and suggestions.

How do i change sharing & permissions on USB HARD DRIVE???

Hello i bought a mac mini 10.6.5 , and i have a simple tech 320g usb hard drive that i used to save pics, videos, etc. from my windows xp laptop. and i want to save pics, videos, etc from my mac to the USB DRIVE. and it and it wont let me!!!! when i go to the drive info it says under sharing and permissions (you can only read) can some one please help.

The drive is formatted for Windows using NTFS. The Mac OS can only read NTFS, not write. You'll have to install something to allow writing, or format the drive as FAT32.

MAC Mini & 2.5 USB Hard Drive Issue

Strange thing happening with a new MAC Mini:
For Christmas, I bought my wife a brand new MAC mini. Everything has been working fine. So, for our anniversary, I bought her a 120 gig USB hard drive (I know, I'm such a romantic
Anyway, ever since I hooked up the hard drive (USB Drive) to her system, it seems that when I first turn the MINI on, the keyboard and mouse completely stop working. once, I had to hold the power button in to hard boot it, then, when it restarted, everything was working fine again.
Tonight, when I turned the MINI on, it did the same thing. No keyboard or mouse. Then, after I hard booted it, the mini never booted up. Black screen. USB hard drive light was on, but, no MAC power light and screen was black.
Now, I just unplugged the USB drive and all is working fine again.
It seems that the USB hard drive being plugged in while powering the MINI up is giving me some grief.
Does anyone have any ideas as to what can be happening here? It is a brand new MINI with Leopard installed. I highly doubt I have a defective MAC because everything was fine until I plugged a USB HDD into it. With the drive unplugged, it seems that it works fine.
No Operating System(s) are on the USB drive. Just pictures and movie files.
Here is the drive I got her:

Any ideas will be greatly appreciated.

Hard Drive Encryption Issue

This is in regard to hard drive encryption issues in my USB Hard drive. I have Windows 7. I was encrypting my USB hard drive and
was able to enter a password. However, I did not receive any prompt to save the Bitlocker recovery key. During encryption process, I received an error. The encryption process was unsuccessful. However, now when I plug-in the hard drive, I receive the
following message on the status bar:
Application and Device Control rule Block writing to removable media. Unencrypted drive found (No_Encrypted_Found) has blocked edpa.exe trying to access Volume
{e3901a75-f1ff-11e1-817c-806e6f6e6963 alpha-numeric number appearing here}
When I try to open the drive, it asks for a password. When I enter the password, I am receiving the following error message:
Bitlocker Drive Encryption failed to recover from an abruptly terminated conversion. This could be due to either all conversion logs being corrupted or the media
being write-protected.
I have read that Bitlocker repair tool can help resolve this issue.
However, I just have the password that I had set to encrypt the drive and Bitlocker recovery key identification. Can this help to get access to my hard drive data using the Bitlocker tool.

Checked this ?

USB Hard Drives Keep Disconnecting or Not Responding

Hi,
This is a long post - but one that I hope someone can offer advice on.
The Hardware
Mac Pro running OSX 10.8 (but this has happened on all versions of the OS i.e. 10.6/.7 etc)
3 x Internal SATA Hard Drives - All working perfectly.
External Drives:
2 x Western Digital My Book 1TB USB Hard Drives
1 x Seagate 750GB Hard Drive with USB2 connectivity
2 x IcyBox Dual Bay USB2 hard Drive enclosures using JMicron Chipsets - these enclosures have 2 x 1TB Western Digital Green in each (totaling 4 TB across the 2 enclosures).
D-Link 7 Port USB2 Hub
The Problem
- USB Hard Drives connected to the Mac are ejected from the system without notice and at random times AND/OR
- The external hard drive remains mounted, but when trying to write to the drive/partitions, Finder throws an error message up saying the operation cannot be completed - error code -50.
- Time Machine: TM will back up successfully several times, before eventually throwing an error up that it cannot create the folders required on the drive.
- The only way to be able to use the drives again is either remount the drive, or in some case, it is required to completely power the drive down and then reconnect.
Re-creating the problem
I have honestly not found a sure-fire way of replicating the problem. It seems completely random. It happens when I am actually sat at the computer, but it also happens when I am away from the computer.
In the past - my Time Machine hard drive has been one of the Western Digital MyBook drives. I also used the second MyBook for SuperDuper backups (extra redundancy). The 4TB drives in the IcyBox enclosures have been used to backup my ripped movie collection.
Recently however - I decided to have 2 of the 1TB drives in the IcyBox enclosures to be TM and SuperDuper backups. I have however reverted TM back to one of the Western Digital drives, purely for testing purposes. SuperDuper is backing up to one of the 1TB drives in the IcyBox.
I am trying various things to see if I can find the issue, but it is such a random event that it is taking ages to even come close to find a problem. Sometimes the drives will stay active for a few days, sometimes only a few hours, even minutes.
Theories
I have several theories as to why my USB drives continually disconnect.
1. The D-Link USB Hub.
Could connecting the drives through the hub be causing the problem? I don't really see how, unless it is a documented case that D-Link USB hubs do not play nice with OSX? To try and rule this out I have connected the current Time Machine back up drive (Western Digital MyBook) directly to the USB port on the back of the computer. The SuperDuper (IcyBox enclosure) drive is currently connected through the D-Link hub. I have removed all the other drives from the enclosures - so at present I have only 2 external drives connected (1 x 1TB Western Digital MyBook, 1 x 1TB Western Digital Green inside one of the IcyBox dual-bay enclosures - connected through D-Link Hub).
2. JMicron Chipset
I have done a bit of research on the internet and there are a few indications that perhaps JMicron SATA-to-USB controller chipsets found in a lot of external hard drive enclosures (including the dual bay IcyBox external enclosures that I have) do not play nice with OSX. If the JMicron chipsets in the 2 IcyBox enclosures is a problem - would that cause issues with other USB devices on the USB bus off the Mac? (i.e. can the JMicron chipset in the enclosures cause devices such as the WD MyBook drives which I assume use a non-JMicron chipset, to experience similar failures?)
3. Green Hard Drives
As I have said, I have 4 Western Digital Green 1TB hard drives inside the IcyBox Dual Bay Enclosures. Could the fact that these drives are 'Green' be causing a problem? They do go to sleep after x number of minutes, but they do wake up when required. But could on the occasion when I have problems, could this be caused by the 'Green' feature interrupting OSX in waking the drives? Coupled with JMicron chipset, could this be compounding the issue?
Possible Solutions
I am prepared to spend money on replacement drives and/or enclosures etc - but I would hate to spend x amount of money and have the same problem. So I am hoping to get some advice on what drives/enclosures are more than likely to work flawlessly with OSX.
Thanks for reading!

FYI - re: the SuperDuper drive that is in one of the IcyBox enclosures.
I just opened this drive up in Finder. I heard the drive wake up, but when I came to copy a file over (tried various file sizes) - I got the error -50 message.
Here is the info from Console.

AirPort Extreme and shared USB Hard Drive

I received an AirPort Extreme for Christmas with the intent of using it to share a network Hard Drive and Printer between the multiple machines on our home network. I've finally gotten it set up with Bonjour on the PC's, and the AirPort Utility on all machines. It's connected via ethernet cable to a Dell PC, and wirelessly to an iMac, a Dell Laptop, my iPhone and a PS3. Internet functionality is great for all devices.
My next step was to connect a Seagate 750GB External USB Hard Drive to the APE. This drive was previously connected to the Dell PC, and was formatted as NTFS. I went through the hassle of converting it to FAT32, I connected it to the router, and both Dell's and the iMac can see the drive. I haven't checked if the PS3 can see it yet, but since I haven't found Bonjour for the PS3, I'm not holding my breath. The iPhone - well, mine isn't jailbroken at the moment.
A few quick hints I learned from doing a lot of web surfing and trial-and-error. These could save people a LOT of time...
+ Don't format a external drive as either an Apple Drive (HFS+) or as a Windows Drive (NTFS) if you plan on using data off it on both a Mac and a PC. Windows won't read HFS+ without a converter, APE won't accept NTFS. It needs to be FAT32 as this is nearly universal.
+ Windows will only format a maximum of 32GB as FAT32. It's a stupid limit, and you have to jump hoops to get it to do a larger drive size.
+ Use the Disk Utility on the Mac to erase the drive and reformat it as an MS-DOS partition. It will work up to a drive of about 2TB according to what I've read. On the Mac, MS-DOS partition = FAT32, and it formatted my 750GB drive as a single 750GB partition.
Now, I've begun the task of copying all our media to the drive. Copied a few pictures, no problem. Copied a few MP3's, no problem. Where the problems start is in trying to copy movies to the drive. We have ripped most of our DVD's to DivX / H.264, to keep the kids from destroying the DVD's (trust me, DVD's scratch EASY in the hands of a 5-year old). So I have about 50 movies to transfer, each around 1GB in size.
Each time I try to transfer a movie to the drive, I get an error "*Error Copying File or Folder*" which displays the message "*Cannot copy BlahBlahBlah: The specified network name is no longer available.*" This also results in the HDD becoming unavailable to the other machines on the network. I've had to un-plug and then re-plug the APE a few times to get the HDD to work again. Sometimes, the copy actually does work, even though I get this message. I know the easy work-around is to connect the HDD directly to the PC with the files on it and transfer them that way, but I shouldn't have to do that - it should just work.
I'm wondering if anyone else has any kind of a similar experience? It appears that I can stream music and video from the drive easily enough, it's the writing to the drive that seems to be the issue. Thanks in advance...
Best Regards,
Jeff

I would think you would have better luck formatting it as HFS+ (Macintosh Extended File System). You'll still be able to see it from your non-Mac PCs.

USB hard drive not detected on reboot

I am running Windows 7 Ulitmate 64-bit on my 2011 15" Macbook Pro. I have a USB Hard Drive (WD My Passport SE - USB 3.0/2.0 - 1 TB).
The hard drive is formatted for HFS+ and I am running Mac Drive 8 to detect it in Windows.
For some reason when I reboot (in Windows), the hard drive won't be there until I unplug it and plug it back in.
This is really annoying! Can anybody help me? I'm pretty good with things like this but I can't think of any reason this shouldn't be working right.

I am having the exact same problem. WD 1TB Passport. USB 3.0 drive. Running on Windows 7 Pro 64 via Bootcamp.
My 1TB Passport is formatted with FAT32 and works with Windows and Mac OS.
I was getting the same problem when I was running Windows XP Pro on the same MacBook Pro. I was hoping the upgrade to Windows 7 would remidy the issue but it did not.
The drive light is on in a steady state when I boot and I have the same symptoms as reported by everyone else above.
In my research, I am leaning towards thinking that it is a power issue related to the cable used to connect the USB 3.0 Drive or something to do with the USB driver for Bootcamp, but researching the WD site suggests it's a power issue, not a faulty or failing drive.
I have a 500GB WD Passport USB 2.0 also attached to my computer, also running FAT32 and it starts up no problem. It's just the USB 3.0 drive that is having this issue.
Also worth noting; the drive is detected properly when I boot in Mac OS X. It's only the Windows side I have to unplug and plug back in to access the drive.

External USB Hard Drive not showing up on Time Capsule

Hi all,
I have a 500 Gb Time Capsule that used to be able to detect my external USB hard drives. I had to store my things for a while and have just started using the Time Capsule again. The TC works fine, however, the same USB external hard drives I used to connect to the TC are not showing up anymore :s They show up on the desktop when I connect them directly to my MacBook via USB. I have been through most of the file sharing options in Airport Utility and System Preferences but have not been able to solve this. I can't think of any settings that would have changed from when they were showing up in the past. Any help would be greatly appreciated. Thx

yosemite won't work with ntfs drives for some reason, i've had the same issue with my toshiba. i thought ok lemme buy another one, and transfer it over maybe it's a driver issue which i've tried over and over, apple support can't figure it out.
here's a simple fix, but the problem is i have an external where all my photography and video files are stored, so i can't access them right now and it's making my life ****.

that does work and make the drive mountable now, but problem being i can't obviously reformat the old drive and lose everything. once the new drive is formatted for mac i can't plug it into a pc to transfer the files from. which is the only problem now. but formatting the drive for mac only DOES work. but you're just screwed and not able to use it ntfs. hope the link helps SOME people.

Airport "sees" USB hard drives, but Finder can't find them!

Yesterday, my iMac's Finder could see my external USB hard drive connected to AIrport, but not today. Airport sees it right now--I've checked and updated it and restarted it. Finder still can't find the drive. I click on my Airport connection in the Finder sidebar, my usual route to the hard drive, but the connection window hangs. And hangs. I need access to the files on that hard drive. Problem is, another iMac using Tiger needs access, too, so I can't disconnect arbitrarily. With that iMac, Tiger's Finder sees the files, and can access them. But not this 20" 2.4G iMac with Leopard 10.5.3. What's going on?

floba,
the first solution, clearing the entire index and letting it rebuild, did not work.
But setting the drive in 'privacy' and then removing it did immediately work, my search window which was left open refreshed instantly to reveal my items. I'm curious however if it will stick..
i have another issue that may be completely unrelated, but maybe not..
i clear my spotlight shortcut key (command+spacebar) because it conflicts with common Adobe app commands i use. But i frequently will find that this shortcut key is RE-ENABLED. At the same time, my shortcut to use Spaces (command+f8, command+arrow keys, and command+numk keys) are CLEARED as if i had never set them. This happens consistently and is frustrating. I don't reboot very often, but i under 10.5.2 i often came home to find my computer has locked up, so it would seem these shortcuts all reset when i reboot, and i wonder if my external drive index is lost every time the drives are ejected.
Vista's completely useless search features were a main reason i gave my PC's away and bought macs. I'm obviously finding these failings frustrating on the mac. I'm even more disappointed at the news Snow Leopard is a bug fix and is selling as a separate OS. Installing additional programs is not an option, i want the OS to do what i tell it to do /rant
