Can't write to external disk after cloning startup disk to it

After cloning my PowerBook Pro's startup disk to an external Thunderbolt drive, and temporarily using that drive to boot-up, the Thunderbolt drive is locked into Read Only mode. How do I enable it to write again? The INFO pane says the following: System privilege: "Read & Write"; wheel: "Read Only"; everyone: "Read Only". The basis for my cloning was to deal with a very full startup disk that I did a lot of video editing on (very processor intensive). The disk had become fragmented to the point that it couldn't access sectors fast enough for editing, so I cloned it over to a G-Tech Thunderbolt drive (using Carbon Copy Cloner), reformatted the MacBook startup disk, then reverse-cloned the copied files back over from the Thunderbolt, the idea being that they'd be re-written nice 'n neat in unfragmented order into their proper sectors. I then ceased booting-up from Thunderbolt, but now the system seems to think that Thunderbolt is still special in some way like a gossling bonded to a surrogate human mother, and it won't let me write to it. Can anybody help me with this?

Have you verified and if necessary, repaired the disk(s) using Disk Utility on your Mac?

Time machine no longer backs up after cloning startup disk

I cloned my startup disk (250 mb) in April 2013 to a 500 mb disk and replaced it with the cloned disk. Before the clone, Time Machine was backing up properly to the 6tb external drive designated for backup. Since installing the clone Time Machine has not backed up anything. Everything (all the apps) is working properly on the cloned disk except, apparently, Time Machine. In fact, I cannot get Time Machine to allow me to make any adjustments to the settings. I went on the Apple Support website to see if I can reinstall Time Machine, but could not find anything. Any suggestions?

If only the system was cloned with CCC it should work, though if you change names who knows.
Delete the plist and turn off and on.
they don't make 6TB so you're using some kind of array or JBOD.

I am getting a message that my startup disk is full, what files can be safely removed to open up space or can I use an external HD for my startup disk?

Converted a FCP X movie into a quicktime .mov file and tried to burn to DVD, message came up that I needed 26.8 GB to burn this movie. I am not sure how I used so much memory. I was not creating Blu-ray movie just a standard DVD. Anyone have any suggestions for what I did to creat such a large file?

It needs free unfragmented space on your boot drive.
So just what and how large and how full is it?
And it isn't 'memory' (ie, RAM), storage is never referred to as memory.
Your system is likely running something later than the 10.6.6 shown.
Clone your system to another hard drive adn then try, or clean it up after backing up with CCC
While at it, move all your home data and media folders off the boot drive (leave a mini ~/Library only)
System
Media and data folders and libraries
scratch
projects
backup partition(s)
etc
more efficient and runs better.
never let the system drive get to less than 30% free, even more.

Is there any way that I can get back my iPhoto? After having hard disk replaced (no backup) and the operating system has been updated to Lion (no disc) I am wondering if iPhoto can be reinstalled with my Leopard discs?

Can't write on external SD card after upgradation

I can't write on my external SD card of my HP slate7 after it was upgraded to KitKat version. It is saying as your Android os is changed you can no longer write on your external SD card. How can I solve this??

Can't write to external disk drivers

Hi guys
I own a 2TB TC. I've connected two WD hard drivers through usb hub and they are all reformatted to FAT32. I can see them and I can have access to them as well but the problem is I can't write to them and I can't copy any thing to them. Can any one help?

Have you verified and if necessary, repaired the disk(s) using Disk Utility on your Mac?

Can't write to external hard drive. I have an NTFS driver.

I have a macbook pro running mavericks and an external hard drive that is NTFS and i can read but i can't write to it. I already have the paragon NTFS driver installed and i know the driver works cos i can use my other NTFS hard drive with no problems. In the "get info" pane under permissions it says i can "only read", but in disk utility under "write status" it says i can read/write. I tried to verify and repair the disk in disk utility and both completed normally with no errors detected.
Does anybody have any ideas on how to deal with this? i would rather not reformat the disk as it has roughly +500GB of work that i have no other place to store temporarily.

Yes, HD are cheap as dirt, buy another HD and format it for your Mac (Mac OSX ext. Journaled)
OR for both PC and Mac in EXFAT format.

Leave it as it is,
$65 for a 1TB HD, or $100 for a 2TB drive. you always need minimum 2 ext. HD for data redundancy protection anyway.

Can't write to external hard drive

I have a MacMini G4 and and iBook G3 both running Tiger. I bought a Verbatim USB 2.0 500 GB external hard drive and reformatted it to HFS+. I can write files from the iBook without any problems. However, from the MacMini, the external drive mounts, I just can't write to it. When I try to change permissions in Get Info, I get error code 195. No luck with Disk Utility or Disk Warrior either. I have a suspicion that the problem lies in the fact that until very recently, the MacMini had only a networked account, now it has two local accounts (the iBook has only ever had 1 local account). How can I fix this without having to reinstall Tiger on the Mini, if at all? Thanks!

Resource Manager Errors (other than I/O)
-195 addRefFailed AddReference failed
So it appears to not be a read/write problem, but either Permissions problem or missing OS components.

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.

Can't write to mounted HDD after updates. (SOLVED)

Im using XFCE as my DE.
I can no longer write to mounted HDD. Neither the 2nd HDD in my computer or my USB backup drive. I can't write to them as root either?!
I can read them just fine, even drag files from them but nothing at all will write to them.
Any ideas??

Can't write to External HDD connected to AEBS

+This is a repost from the SL Discussion...hopefully someone here can help...+
I am logged in under my account, which is the Administrator Account. I am unable to write to Seagate 1 TB external HDD connected to AEBS base station.
Under "Get Info"->Sharing and Permissions it reads "You have custom Access" and then shows just one account, "everyone" and this is a "Read Only" account. The format of the External Drive is shown as "Appleshare" (actual drive is formatted as NTFS so my Dell PC can read/write, which is functioning perfectly).
I tried to change the "everyone" account to Read and Write but Mac 10.6.3 won't let me because "I don't have the necessary permissions".
So then I tried to add another account (clicking the "+" sign) but it again rejects me because the account "isn't a valid name" although I am using my account name.
I was able to read/write to this drive under Leopard but lost that function when I upgraded to 10.6.3. I can read the files on the drive and copy them to my iMac but I can't copy back to the drive. Is this a Finder problem?
How can I get the permissions changed on this external drive so I can read/write from my Admin account?

Okay, it is formatted as FAT32.
I checked under Airport Utility and there are (2) accounts that have permitted access, Dad (Read/Write) and Mom (Read Only). The drive is not corrupted as I can read/write from the Dell PC without any issue and I can "Read" from my iMac.
When I right click on the drive, "Get Info" and then check "Sharing/Permissions", there is only one account shown "everyone" (all small letters) with "Read" access. This account does not show up under "Airport Utility" so it is an account that Finder assigned.
My other two accounts, that are correctly shown under Airport Utility, are not shown in Finder. It seems like this is a Finder Problem and Finder (under Snow Leopard) won't let me access the drive.
So how can I change the Permissions in Finder? Even if Finder lets me add another account that can read/write, I'll be happy. But it won't let me add any accounts, it simply says "Invalid Account Name".
I'll try the direct hookup to the iMac as a last resort but this drive has all of my photos backed up on it so I don't want to mess around too much with it. I have photos on other drives as well but it is a big pain to reload from the other drives...it is around 300 Gb of photos.

Time Machine and a Cloned StartUp Disk

I have a BootCamp partition on my startup disk that is painfully too small. In the next couple of hours I will have a 2 TB drive delivered to replace it. Splitting it in half between Mountain Lion and BootCamp/Windows, I have addressed any issues I thought would arise. I plan to clone the Mac partition of my current drive onto the new and just do a clean install of the BootCamp/Windows partition. Backups done, preparations taken care of, my final concern has come to mind...
Will Time Machine continue its incremental updating from a cloned drive?
In the past, any time I've changed computers the backup wasn't available. Other forums I've checked says that Time Machine allies itself with the MAC address of the computer it backs up. Some hinted that there's a paring with the drive it backs up as well. Is this true? I'm not changing Macs, I'm not even changing the data; I'm just changing the drive its on.
It's not a big deal if I lose the backup though I'd prefer not having to go through that initialization again. It just seems logical that Time Machine would view the clone same as the original. Any feedback?

I personally only have the Time Machine backup. The main advantage of the Time Machine backup is that it happens automatically every hour that the Mac is active, incrementally backing up files that changed. With a clone, it is only as up to date as the last time you performed a cloning run. The second advantage of Time Machine is that you can +go back in time+ to an earlier state, not just restore to the latest state. With a clone, all you have is the last backup.
The advantage of a clone is that you can boot from it. So if your hard drive fails, you can still use your iMac to wrap up necessary work before sending your iMac in for repair.
It you have two external hard drives, there would be nothing wrong with doing both. Make a clone about once a month and let Time Machine handle the up-to-the-last-hour backups.
If you had to choose one, I would use Time Machine.
It is remotely possible that your primary storage drive and your Time Machine drive will fail at the same time. So I do keep my most critical files (just the files) backed up to second separate storage location. I do that manually.

IMac G3 freezing after changing startup disk?

Hello.
I bought a iMac G3 I few months ago just for a hobby and have been playing around on it.
This morning I noticed two other previous system folders in the system folder.
I then opened "startup disk" (I think that is the name) and chose to restart with "Previous system folder".
When it re-booted it opened up differently, had a new background and made sound effects when clicking and scrolling.
I decided to change the startup disc to "Previous system folder1" (which is the other previous system folder)
This time when restarting it booted normally until the desktop icons loaded. The mouse and keyboard froze and then a message popped up saying "To use your internal modem you need to select the country from where you will be using your computer". I try to use the mouse and keyboard to select, "Australia" and then "OK" but as previously started the mouse and keyboard are frozen.
When booting up I can use the mouse and keyboard on the loading screen until it freezes when the desktop appears.
(The computer was working amazingly before I stupidly changed the system folder)
Why is this happening. How do I return to a previous system folder when it keeps freezing.
Here is a youtube video showing you what happens:
https://www.youtube.com/watch?v=uYURgG2W5x4
Please note, I do have all the software CD that came with computer, however for some reason discs won't work on the computer they are unrecognizable.
All keyboard commands do nothing for example holding down shift into safe mode still freezes.
Thanks in advance!

I'm not sure what OS you are running here.
There is a way to set what os boots from the firmware. Not sure how.   Look tomorrow. let me know via another post.
For classic, you could try hold the
space bar
then booting. or is it the shift key?
If this is a slot loader, try:
The startup manager will list all of your bootable partitions then give you a choice of which to boot. Hold down the option key then power on. Continue holding down the option key until you see the startup manager. This brings up the startup manager. Click on your hd or disc. Click on right arrow key.
Restore Tiger 10.4 & Leopard 10.5 DVDs are available from Apple by calling 1(800) 275-2273. Have your serial number ready. Have your credit card ready too. There may be a small fee.

Startup keys
http://macs.about.com/od/macoperatingsystems/qt/osxstartupkeys.htm
I have a list of magical boot key sequences:
    Key Combinations-- Effect
    * mouse down -- Eject removable media ( I think Boot ROMs prior to 2.4f1 excluded the CD drive )
    * opt -- Bring up OF system picker on New World machines.
             iMac g3 400 or newer machine
    * cmd-opt -- Hold down until 2nd chime, will boot into Mac OS 9 ?
    * cmd-x (or just x?) -- Will boot into Mac OS X if 9 and X are on the same partition and that's the partition you're booting from.
    * cmd-opt-shift-delete -- Bypass startup drive and boot from external (or CD). This actually forces the system to NOT load the driver for the default volume, which has the side effect mentioned above. For SCSI devices it searches from highest ID to lowest for a partition with a bootable system. Not sure about IDE drives.
    * cmd-opt-shift-delete-# -- Boot from a specific SCSI ID # (# = SCSI ID number)
    * cmd-opt-p-r -- Zap PRAM. Hold down until second chime.
    * cmd-opt-n-v -- Clear NV RAM. Similar to reset-all in Open Firmware.
    * cmd-opt-o-f -- Boot into open firmware
    * cmd-opt-t-v -- Force Quadra AV machines to use TV as a monitor
    * cmd-opt-x-o -- Boot from ROM (Mac Classic only)
    * cmd-opt-a-v -- Force an AV monitor to be recognized as one
    * c -- Boot from CD. If set to boot to X and no CD is present, may boot to 9.
    * d -- Force the internal hard disk to be the startup device
    * n -- Hold down until Mac logo, will attempt to boot from network server (using BOOTP or TFTP)
    * r -- Force PowerBooks to reset the screen
    * t -- Put FireWire machine into FireWire Target Disk mode
    * z -- Attempt to boot using the devalias zip from first bootable partition found
    * shift -- (Classic only) Disable Extensions
    * shift -- (OS X, 10.1.3 and later) Disables login items. Also disables non-essential kernel extensions (safe boot mode)
    * cmd -- (Classic only) Boot with Virtual Memory off
    * space -- (Classic only) Trigger extension manager at boot-up
    * cmd-v -- (OS X only) show console messages during boot
    * cmd-s -- (OS X only) boot into single user mode
Did not work simply 'z'?
You could buy an external DVD drive. It needs to be firewire and bootable by Mac OS. If you have another PPC with firewire, you could try target Disk mode and installed tiger that way.
You need to figure out the level of your firmware before installing 10.2 or greater. ( The PC name for firmware is BIOS. ) Installing 10.2 with a down level firmware will most likely make your iMac unusable and difficult to fix.
What is Open Firmware?
The firmware on a PPC is called Open Firmware. Open Firmware software receives control when you poweron your machine. It does some hardware testing and some hardware configuration then passes control to your version of Mac OS.   It reside on a PROM ( program read only memory ) chip on the logic board.
Figuring out what level of Open Firmware you have?
1) Mac OS 9.x or 8.x, you need to use the Apple System Profiler.
Apple -> Apple System Profiler
2) Mac OS X, use the System Profiler.
Apple -> About This Mac
click on the More Info... tab
click on Hardware
read the Boot ROM Version
3) Open Firmware, boot into Open Firmware.
