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.

How do I change all permissions on a hard drive in one shot?

I am a video editor who just moved a few hard drives into my new Mac Pro.
Unfortunately, all the footage is 'Owned' by the 'User' of the old Mac Pro. This means that I can't move or rename files, among other limitations I'm certain that I just haven't run into yet.
Instead of going one by one unlocking and adding myself as an owner with read and write capabilities, is there anyway to apply such a change to all files and folders on a hard drive in one action?
Thank you very very kindly!

Select the drive or folder of files, then Finder > Get Info and apply your permissions and at the bottom is a spoky thingy that you click and apply to enclosed items.
Don't do this on a boot drive, only onto folders you know to be of the older user account. Not program folders or system folders as they have other permisssions settings.

How do I change the name of my hard drive which the photos and libraries are located on without having to relink and recreate folders for photos?

When I have tried to change the name of my hard drive which my photos and catalog are stored on, when I try and access the new catalog in the new destination yet still same physical hard drive it unlinks all the photos and the folder structure.
Any way to keep the photos or at least the year folders so as to more easily relink?

In the Library module, in the Folders tab on the left, do a right-click "show parent" until you can see the root of the drive.
From there, if you cannot rename the drive from there, then rename it in the OS finder/explorer. Then you just need to reconnect that one root directory or drive entry and Lightroom will do all the work for you.

How do I change the "Permissions" on an external drive to 'read & write'?

I am experiencing a problem with an external Hard Drive that I'm now using with my iMac, that used to be connected to my old PC.
I can't write anything to it. When I check its "Info", under the "Sharing and Permissions" tab, it says "You can only read".
Does anyone know how to change this so that I can both read and write to the drive like normal?

Hello br121
You will need to *Partition and Format* the External Hard Drive.
+Warning save all the data to another drive, partitioning and formatting will erase your drive.+
If you want to setup the drive exclusively to use with the iMac (Time Machine, Cloning your Mac HD or storing large files) you will have to reset the partition map scheme to *GUID Partition Table* and format to *Mac OS Extended (Journaled).*
If you want to setup the drive so that both Mac and windoz systems can read and write to it, then you will want to reset the partition map scheme to MS-DOS and format to FAT-32
+(keeping in mind that FAT-32 has a single file size limit of 4GB)+
The following article by Ken Stone was written before Snow Leopard, but it's still very helpful because basic Disk Utility partitioning and formatting is the same.
http://www.kenstone.net/fcphomepage/partitioningtiger.html
If you get stuck you can refer to Ken's article above, Disk Utility HELP and or come back here.

How do I change the format of a hard drive I have to make it work with my imac

My friend has given me a hard drive to put some stuff on it for him, but it's formatted to Windows NT File System (VTFS) and I need to change it to MS-DOS (FAT32). How do I do this?
Thanks

If you don't want to format the external disk, you can use a third-party application like Parallels NTFS.
That's the most recommended way. However, if you want to format your external disk in FAT32, you can do it without any problem.
First, open a Finder window, select the external disk in the Finder sidebar under "Devices", and copy all the data to a different folder.
Then, open Disk Utility (in /Applications/Utilities), choose your external disk in the sidebar, go to Erase tab and erase the disk. Make sure you have selected "MS-DOS (FAT)" in "Format". If you need detailed steps to do this, see > http://pondini.org/OSX/DU1.html
Finally, copy all the data to that external disk. You can also use exFAT, but in that case, you will have to format the external disk in a PC

How do I install Yosemite on a USB hard drive

I need to understand how to install Yosemite on a USB hard drive

Install it as normal, except that you select the USB drive when asked where you’d like to install it. The volume you’ll be putting it on needs to be formatted as Mac OS Extended (Journaled).

How do I resolve spontaneously unmounting external USB hard drives?

I've seen a few other posts on similar topics, but seem to fit my experience. I have two 2 TB Seagate hard drives I bought for Time Machine backups, Atlantis and Phoenix. I've had the drives for probably six months, and they worked fine for much of that. Both still have lots of free space. However, in the past two months or so they have started spontaneously unmounting, usually a week or two after being remounted. The frequency seems to be increasing. I've upgraded to Mavericks, but this does not seem to have made any difference for the better or worse. One other change since getting the drives is that I have added a UPS to keep the drives and host Mac mini up for a few minutes in case of a power outage. I haven't seen evidence that the unmountings are the result of power outages. I did find this in the system logs at the time of the most recent Atlantis unmounting, but don't know what to make of it:

They did again last night, the soonest they've ever unmounted after being restarted. After further investigation in the Console app I found the entries below.

Looks like hardware failure to me, but it's hard to believe both drives would be failing at once. They are both connected to the same USB hub, so I guess I'll try replacing that first.

How do I change the permissions on external drive?

Hi
How do I change "Sharing & Persissions" on an external drive. The drive has a note "You can only read". My account is "read and write" > Fetching is "read and write" and > Everyone is "read only". I want to change Everyone to "read and write".
Thank you

That is if you wnat to open it to everyone.

Changing external USB hard drive into a FireWire Drive???

I have been reading in some of the other discussions about how it is possible to change a USB external hard drive into a FireWire external hard drive. Is this true ??? I recently pruchased an external USB hard drive only to now find out that I cannot use it to boot from. Apparently OSX will only boot from a FireWire drive ??? Is there some way to change my current external USB hard drive into a FireWire compatible drive or do I have to purchase a FireWire drive ??? Thanks.

All I can remember was an internal USB/firewire hub (for PCs, by the way), I haven't seen external adapters like cables; but you may simply ask in your local computer store about.
Yes, you can boot only from firewire drives. I was told that it is possible the new Intel Macs are able to boot from USB drives, but haven't had the time to verify this so far.
A possible solution may be to remove the harddisk from the USB enclosure and put it into a firewire case. This should work and you just need to buy the firewire case without the need for another harddisk. Just ensure that the case is able to take your harddrive (2.5" / 3.5" drives, connection interface).

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?

stojic wrote:
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 to i get my usb hard drive to auto show on desk top

Hi
I have a small business and so multiple macs with 1 single external hard drive for storage
One of the Macs automatically connects to the USB hard drive when the mac starts up in a morning, whereas with the others you have to search for the shared drive and manually connect to it.
We have now changed to a new hard drive and would like all the Macs to automatically link in the morning and so wondered how this is done. Also the older mac is now still looking for the old drive and I cant stop it!
Hope this makes sense?
Hope someone can help
Cheers
Michael

You need to find the IP of that drive.
If they in fact do show up on the Desktop, then create a new Folder maybe named Shares on/in the Desktop, drag all those Shares shown on the Desktop to that Folder, drag that Folder to the right side of the Dock between Applications & Trash, this should give you a popup menu to select from.:-)
Mount that Share once, then once the Globe Icon shows up on the Desktop, drag that Globe Icon to the right side of the Dock between Applications & Trash. You now have a Dynamic Mount, a quick click on the Icon in the Dock will connect you.

Airport Extreme + shared USB hard drive // Mac + PC Access

We are getting ready to purchase an Airport Extreme for our home network. Here's what we are working with:
1) Airport Extreme
2) MacBook
3) MacMini
4) PC
5) TBD USB hard drive that will be connected to AirPort Extreme *for use as shared hard drive*
From the Apple website, regarding the Airport Extreme "Hard Drive Sharing":
+How does it work? Just connect the external hard drive to the USB port on the back of your AirPort Extreme and — voilà — all the documents, videos, photos, and other files on the drive instantly become available to anyone on the secure network, Mac and PC users alike. It’s perfect for file sharing, collaborative projects, and more.+
Can anyone recommend a specific brand and model USB hard drive that they have experience with in this scenario that was/is used as a shared drive that is accessible from both Macs and PCs?
I ask this question because I have a WD external hard drive that did not play nice - it was either PC or Mac, not both.
Thanks

I have 1-4 and a Seagate FreeAgent Desk drive (not an endorsement, just answering your question), and can access the drive from all of 2-4. How you format the drive and/or what files you store on the drive will affect your ability to access/use those files on the drive from Mac/PC. For example, I can't use my iTunes library stored on the drive from the PC, as it's formatted for Mac. Honestly, I never have accessed the drive from my PC until you asked this question, but it worked!

What packages to install, and how to install in an USB hard drive

Hello.
Well, as I said in another thread, I want to install in an USB hard drive. But I don't know how, because it hasn't graphical installer, but text installer. I tried in a virtual machine, and it was fine, but when I want to start it, an error appears, "Was not found a bootable system" or something. Maybe a VM is not as a computer, but... well. I didn't change anything while I was installing GRUB, and I know that I've to install it in /dev/sdb.
And I want to know too, what packages to install and what packages don't (the ones which are neither "base" nor "base-devel"). But I'll install sudo, links and ndiswrapper (for wifi).
Thanks, and excuse me if my English is bad.

Gotta use the wiki my friend and this one is even translated into Spanish:
https://wiki.archlinux.org/index.php/In … C3%B1ol%29
As to your question about which packages you'll need beyond those in base and base-devel - that depends on what you want on your system... no one can answer that but you!
Welcome to Arch.

How to use iPad (4th gen) to edit with iMovie - but using an external source such as a USB stick or external USB hard drive

Want to use my iPad (4th gen) to edit a movie using iMovie - easy enough if the movie file is on the iPad - but what if it's too large - can I keep the source file on a USB stick or external USB hard drive and edit from there? How can you do this?

You can't export any type of file using the camera connection kit, so a USB flash drive or SD card won't work.
There are some wireless external hard drives that can be used with the iPad.
The Kingston Wi-Drive, which costs $50 for the 16 Gigabyte, and then $30 more for every 16 gigs more. It works by you turning it on and then accessing the files on it from an app that you download on your iDevice. You can access music, movies, and other stuff. No connections or anything, it works like a WiFi connection, you connect to it from the setting on the iPad under wireless networks.
Then there is the Seagate GoFlex, which some would recommend over the Wi-Drive. But this one costs $199 and had 500 Gigabytes of storage. It works the sameway as the Kingston: no wires, runs over its wireless connection. You can actually fit up to 300 HD movies on it.
Another option:
Expand your iPad's storage capacity with HyperDrive

How to restore machine using a TM backup on a usb hard drive from older imac to a brand new iMac?

My imac (the one that had a superdrive in it), had a broken superdrive and was sent for repair. Whilst being "repaired" the screen was broken. I now have a brand new imac albeit without a dvd drive. My question is how to I restore my the old TM back up which had been made to an external usb hard drive to the new imac. Help files say that I should not restore from a TM file to a different machine and that I should use migration assistant. Whilst I can see the external usb drive in TM it is not being recognised in Migration assistant when I click on back up from a TM backup on another machine or disk.
Any ideas?
Just noticed that this new machine is running OSX 10.8.4 the broken imac was on mavericks

This is very simple first run Software Update on the new machine and get your machine upgraded to the most recent version of Mountain Lion 10.8.5. Install all other software updates Apple recommends in Software Update. Then care fully read Pondini's guide on using Migration Assistant located at:
http://pondini.org/OSX/MigrateLion.html
Your migrated data will be in a new account, to access it log into the new account.
Also DO NOT repeat DO NOTuse Wi-Fi to migrate data, if your TM backup drive uses USB, then connect it via USB and follow the on-screen instructions as described in Pondini's guide.
