Aug 08, 2017 Prior to OS X Yosemite, there was no simple way to rename multiple files at the same time on the Mac. Some people set up Automator rules. Others tried workarounds to rename files in third-party apps. There are two likely reasons that you can't change the name of your hard disk, folder, or volume in Mac OS: If you are using Mac OS X or Mac OS 9.x with multiple users, and you aren't logged in as an administrator or the owner, you won't have enough privileges to change the names of hard disks, volumes, and many folders. I am trying to use Terminal to rename my file, but it always says permission denied. I have tried the following: sudo chmod u+wrx test.txt mv test.txt test2.txt it doesn't work. So, I try to check the details of this file. Ls -l test.txt -rwsr-r-@ 1 I think it should allow me to rename it. I am using Seagate Backup Plus Drive, and Mac 10.14. Mar 29, 2019 Rename a system drive. Locate the icon on the desktop for the volume, partition or drive to be renamed. Click the volume icon and press the return key on the computer keyboard. Type the new name into the field that appears and press the return key again.

'Hi there, do you know how to make the external hard drive accessible again when it shows as 'Read Only' on Mac? I'm having this problem that my Seagate hard drive suddenly turned to read-only this morning when I connected it to Mac. I could only read and view saved data on the drive, but can't use the data on it. If you have any clue to fix this problem, please tell me. Thanks very much.'
/free-dealer-management-system-download-for-mac.html. Right-click your external storage device, select 'Get Info', and if you see 'You can only read' at the bottom, you are encountering one of the commonest problems with an external hard drive. When your external hard drive or other external storage devices show up as 'Read Only' on your Mac, you can:
You can't:
Why can you only read the external hard drive that is connected to your Mac? There are three possible reasons.
Right-click your hard disk and select 'Get Info', if you find the external hard drive in NTFS format, that's what the cause is. The incompatibility of the file system is the main cause. NTFS is a file system that is optimal for Windows-based computers. Although the Mac operating system allows you to read the files on the external hard drive, you can't write files to it because the way that NTFS writes data to the device is incompatible with the way macOS doing it. (Go to the Fix.)
An external hard drive is subject to the access permission set up by OS X for all files and folders on the system. When you use the device on another computer with a different OS, the permission settings with it may not be recognized or prevent access to the files on the hard disk. (Go to the Fix.)
Another common cause for the external hard drive 'Read Only' problem on Mac is the formatting errors of the storage device itself. If you see a warning that says the device is only being mounted in read-only mode while connecting, your hard disk is diagnosed to have formatting errors that prevent you from writing files to it. (Go to the Fix.)
Identify the cause that leads to the 'Read Only' error on your Mac from the information above, then follow the corresponding solution to solve the problem with ease.
Based on different reasons, there are three solutions to the problem.
If your external hard drive is read-only on your Mac due to its NTFS file system, you can fix it by reformatting the device to a Mac-compatible format with Mac Disk Utility. Before that, remember to back up your external hard drive quickly with data backup software since the formatting will erase all the files on the device.
Step 1: Launch 'Disk Utility'.
Step 2: In the list of available drives on the left, choose the problematic external hard drive. Then click the 'Erase' option in the main window.
Step 3: Choose a proper file system and rename your hard disk. (Both APFS and Mac OS Extended file system are Mac-exclusive. Thus, if you want your external hard drive to be both Mac and PC compatible, choose MS-DOS, also known as FAT, or ExFAT instead.)
Step 4: Click Erase to reformatting your external hard drive.
Wait for the reformatting process to complete and then go to the information window, this time you will see the 'You can only read' has changed to 'You can read and write', which means you can read and write the drive on your Mac normally.
Generally speaking, when a storage device shows up as read-only, you can still copy files off of it. If you cannot view or see all saved data on the drive, don't worry. After you format it, you can use the professional Mac hard drive recovery software - EaseUS Data Recovery Wizard for Mac to get back your lost data on the drive with simple clicks:
Step 1. Select the disk location (it can be an internal HDD/SSD or a removable storage device) where you lost data and files. Click the 'Scan' button.
Step 2. EaseUS Data Recovery Wizard for Mac will immediately scan your selected disk volume and display the scanning results on the left pane.
Step 3. In the scan results, select the file(s) and click the 'Recover Now' button to have them back.
If you are sure the problem is caused by the permission settings, you just need to ignore the permissions to solve the 'Read Only' external hard drive problem on your Mac.
Step 1: Right-click your external hard drive shown on your Mac and select 'Get Info'.
Step 2: Expand the 'Sharing & Permissions' section, then click the lock to authenticate.
Step 3: Check 'Ignore ownership on this volume'.
If there is a formatting error on your external hard drive that makes the device read-only, you can use Disk Utility to check the errors and repair the external storage device.
Step 1: Go to 'Disk Utility'.
Step 2: Highlight the read-only external hard drive, click 'First Aid' in the top center, then click 'Run'.

Interesting hint, but does anyone also know a way to mount network volumes to a special directory?
I might be able to help with this, but I'd need more info: What sort of network mounts? NFS? AFP? What exactly do you want to do?
I use automount to mount an NFS volume at startup. To get the network mount to show up somewhere other than the default mount point (/private/var/automount/server_name), I use an automount map. I also use a symlink for other/additional mount points. I do not know how to do this with AFP mounts (i.e. mounts created via 'Connect to Server'). There are also methods using NetInfo Manager, but I've found them less reliable.
If you're interested in learning more about what we're doing, let me know and I'll post detailed info on my blog:
http://systemsboy.blogspot.com/
I would be extremely interested.
I am using NFS to mount the home directories for my family on all our Macs. I currently have one server and three other systems. I have been using NFSManager to create the shares and activate connections. This stores the information in NetInfo. However, it requires manual reconnection after reboot before anyone can log into one of the network accounts. Since I have added a 10.4 iMac G5 to the mix, things have gotten even worse. If the G5 goes to sleep when being used by one of the network accounts, the network account and system are totally hung when waking requiring a power cycle of the system.
I would like a more reliable setup for this since I don't want to start synchronizing home directories on all 4 machines. My server is an older G3 iMac with two mirrored firewire drives. So information redundancy and synchronization overhead are not needed.
Ugh! That sounds rough.
So I've posted a rather lengthy and detailed article about the method we use in the lab to, among other things, automount NFS exports on our client systems. I'm still proofing it, and there may be a lot you don't need, but hopefully there's something you can use. If you have any questions, feel free to use the comments and I'll answer as soon as I can.
Good luck!

Just curious why you're using NFS instead of AFP on an all-Mac network. There are still apps that use resource forks (e.g. in preferences files), which you lose with NFS.
This is an interesting hint. But in my clean installs of Tiger, I have no fstab file. I do have /etc/fstab.hd, which only contains the following text:
'IGNORE THIS FILE.
This file does nothing, contains no useful data, and might go away in
future releases. Do not depend on this file or its contents.'
Anyone know what's happened to fstab in Tiger?
fstab has always been used only in single-user mode -- that's why you need to load the info into NetInfo for it to have any effect.
-Esme
Ah! Thanks! I missed that NetInfo part.
I never knew how to get tht UUID number for a drive. And now I do. Cool.
It's just not installed by default anymore. fstab worked fine in Jaguar and Panther in multi-boot mode. I've used it several times when setting up failover clusters. The main thing to remember is that you had to use the disk name as defined for the partition, not the traditional disk number as you would on other *NIX. Mac OS X has dynamic disk mounting and the disk number might change from boot to boot.
AFAIK it works fine in Tiger as well, but I've not tested it yet.

Breaking my server to save yours.
That's incorrect, Esme. I've used an entry like:
UUID=383FD42C-EA30-48A4-B260-BE51F9A206FC /Users hfs rw
.. in /etc/fstab on 10.3 & 10.4 to mount the users volume on /Users without loading data into NetInfo.
Works flawlessly, except for an ignorable 'no such file or directory' warning from the mount command run from /etc/rc when booting.
I disagree with gidds' post that claims the symlink method of users volume relocation is 'much safer and easier'. Well, at least the 'safer' part because (IMO) there's less risk of some obscure error with a directly mounted volume than referencing it through a symlink. Pretty sure I've read of trouble (maybe a bogus installer?) caused by such a symlink although that was a few years ago and may be irrelevant nowadays. Whichever method works to your satisfaction is what's best for you. :-)
ln -s /Volumes/mydrivemypath/mynewdir
Alternatively, if you just want to move your home directory, simply set a new home directory in NetInfo. (That lets you put different home directories on different drives, too.)

That's what I do and it is the easiest way to go for moving the home directory.
Cool.. thanks for the tip! For some reason I wasn't able to get that working in 10.3 but I'll give it another try on 10.4 because of your success.
