OS X :: External Hard Disk Changed From "Read And Write" To "Read Only"
Aug 12, 2010
I have an external Transcend HD, which has been working perfectly fine for around 5 months now. It is NTFS, and I use NTFS-3g and Macfuse. Been running fine. Was able to read and write. Suddenly I am only able to read though. I go into the "Get Info" pane and the option to choose whether I want to read and write, or read only is gone, and all that it says is "You can read only". getting this back to read and write is really appreciated. I really need this disk.
This issue has been killing my work flow for quite awhile. I have a G5 dual 2.0. I can barely read or write files to an external hard drive. Say I try and copy 1.56GB of audio (12 files) from my external drive it will start to copy then stop at 500mb for minutes then start moving as normal and stop again around 900 for minutes.. then again at 1.4. This also happens when writing.
Here is the confusing part. This happens with two external drives (different models) with firewire 400, 800 and USB. I have reinstall OSx. I have repaired permissions and ran repair disc on everything. These hard drives work FLAWLESS with my Macbook Pro as well. Gr what can this be? It takes forever to copy data to or from a drive which is often how I transfer audio between my desktop and laptop. I should soon have Mac Pro money and this crappy G5 can go out the window. I am on 10.4..
I recently borrowed my brother's laptop to use as a media station for listening to music from, and watching movies, in order to free up some space on my main macbook. In trying to migrate some files over, I discovered that my hard drive, a 320 GB WD Elements drive, is having some problems which I've never encountered before. It has always worked fine in the past, but now I can't transfer any files to or from it, from either computer. In all of my troubleshooting, I've gotten various errors, (-36, -50), and various messages saying how the device can't be read or written from, or how some files contian unreadable data, etc.Disk Utility found an unused node when verifying the disk, and notified me that the disk needed to be repaired.I then used Disk Utility, which said it was able to successfully repair it, but the same problem remains, and after verifying the disk, it still says it needs to be repaired.I've tried to find any files that may be causing the problem, and was finally able to delete a seemingly troublesome file that was stuck in my trash bin from the external drive after trying various apps, (ie Trash It, Cocktail, What's Keeping Me?).This didn't end up solving anything...I've used terminal to eliminate some other potentially problematic files, with no luck still, and I'm not too confident with Terminal so I don't want to be messing around too much without more guidance.
I've used Disk Warrior to try to solve the problem, but still with no success.When I use the app to Check All Files and Folders, it does so for only a few seconds, then reports that "An unexpected error ocurred while attempting to perform file operations" for several files, and that several files' "Property list is damaged and cannot be repaired". When using Disk Warrior to REBUILD the drive, the app pauses for about 15 seconds, then says that it can't be rebuilt because it is in use.Again, I've used the What's Keeping Me? app to kill any activity with the drive, and the same error occurs.I've spent a lot of time trying to sort this out.
hey all, this has been really frustrating for me today. i want to be able to write to an external HDD that's formatted in NTFS. today i find out it isn't possible to write to this file system on a Mac and that on FAT32 it is possible. however, FAT32 can't address files larger than 4GB so this hurts me a lot. are there any other file systems that'll allow me to read and write from a Mac? my goal was to use freeNAS to build a NAS with an old tower and connect my external hard drives to it, but if i can't write to them this may not be possible.
I bought a Seagate Free Agent Go Flex External drive. I transferred all my files from my previous external HD.
When I went to access my folders on my external HD, the folders are all locked, with Sharing and Permission section in the Information "Everyone: Read" only! I can't change any of the information or move things! All of them are locked and "read only." I know how to change it, but only manually, individually. I have several hundreds of folders and I don't want to manually change all of them to "Read & Write." Is their a way to let me re-set the folders to "Read & Write" easily??
I have an external hard drive(seagate 250 NTFS format) which i have used on my windows 7 computer now that i'm trying to load the information onto my macbook pro (10.7.4) it will not let me change the permissions nor duplicate the files. How can I be able to edit and save the information to my mac from the external drive??
When I connect my external hard disk (Maxtor) to my Mac Book Pro, I am not able to copy/transfer files to it, though I can copy from it to my Mac. How do I change the permissions from Read Only to Read and Write?
I know this is lame, but I searched and can't find a solution. When I click on a day in ical it says it is a Read-only calendar. I repaired permissions, but it still says read only. The strange part is, in the Get Info screen, it says Read-Write for all the users.
I'm buying an external hard drive to use as a backup for my MacBook but also as a network drive that all the computers connected to my router (Airport Extreme) can use. There are two MacBooks and two PCs that connect to the network. I only need my MacBook to be able to write to the hard drive but I need the two PCs to be able to access and use the files on the hard drive. I was going to get a 1TB external and give it two partitions. The first partition is going to be the Time Machine backup for my MacBook and the other will be accessed by all computers on the network. What format will the second partition need to be so that both MacBooks and both PCs can view and use the files? Also what external hard drive would you recommend?
I may end up getting another external hard drive & would like to be able to stay with NTFS so I can use it with either PCs or macs, there is a PC in my home & I would like to be able to use it between the PC & my macbook pro. Does anybody know of good reliable software that does not hog resources that will enable me to read & write NTFS on my macbook pro?
What is the standard tool to test your hard drives read/write speeds? I'd like to test my new SSD to see how fast it really is. I've heard you cant trust XBench for that which is the only thing I have to use.
I have an early 2009 macbook, with 320 GB hard drive and running OS Lion, after i upgraded my os to lion, the computer ran perfectly normal, although a little bit slower than running snow Leopard. However, recently I notice my mac become very slow, got rainbow wheel even when i open the safari. then I use the black magic to test the hard disk speed, it appears the read and write speed is only a little over 30mb/s.
i have recently change my keyboard at apple store, I notice my mac slow down after that, do you think it would related?
I got my MBP only a couple of days ago , but noticed that my Calendar and Accuweather widgets seem to have changed the font style.The numbers are hollow, instead of solid, which makes it hard to read. Is this normal, and is there any way to change it?
I was trying to write xmp data to my photo's, when I got errors on photo's in certain folders. ?Writing XMP Metadata? did not complete successfully. It seems all jpegs in a few particular folders have generate this error. I then noticed all those files were lacking a creation date. When trying to copy the "image taken on" date to the "creation date", using A Better Attributes, I didn't appear to have the right permissions.
Now this is, to me at least, the weirdest part: when I open Get Info on any of the images, it says "You can only read", even though all privileges are set to Read & Write (screenshot attached). The folder itself says "You can read and write". So far I've only seen this on files/folders on an external hard drive, formatted Mac OS Extended (Journaled). It's a WD My Book, connected via USB through a hub. Anyone ever seen this before? Is there anything I could try to fix this?
i used to have a bunch of files on my hard drive before i sold my mac pro
i backed everything up on an external hard drive so i can keep it until i received my imac. now i have my imac, and when i try to transfer over the files to my imac, or another external hard drive, sometimes the copying stops and says something along the lines of "you do not have permission to copy this file"
so i guess some of my files got messed up, putting them in "Read only" mode.
i know i can go to "Get info" and then manually change it to "read and write" mode but honestly theres so many files it would take a lot of time.
is there a script, or an app i can run that could scan my whole external hard drive so it will go thru each file in their own specific folder and change the permissions to "read all write all" without me doing it manually one by one?
I am sure this is a simple question, but I am having a problem going from windows to mac with an external hard drive. I can read and write to the drive on any windows PC. On my macbook pro laptop, I can only read. It will not let me write or erase anything to the drive. Does this have to do with the drives formatting? If so which format will let me both read and write on mac and pc?
Recently I purchased an external hard disk, to put all of my pictures of my baby due to space limitations on my internal laptop drive. Since my Canon camera 10 megapixel pictures take up a ton of space this was occurring at an alarming rate. My intention was also to back up to DVD but never got to it. This is both a comment and a question.
Now said baby, is getting really good at pulling cords etc. He managed to do this on the external drive firewire cable. As far as i know the drive was not in the process of actually writing. However, after a few minutes and trying to re-plug the drive the OS crashed with a Grey Screen of Death hardware error that tells you that you need to push the power button..
This apparently corrupted the drive's directory. Upon reboot the drive would not mount. Since there were time machine backups on the drive too Diskwarrior was not able to reconstruct the drive in the built in memory available on the computer. Time machine stores millions of files and Diskwarrior apparently wants to keep it all in memory at once. Since my computer has 2GB you would hope that would be enough but apparently not. So that failed. Other utilities seemed to be able to find the files but not restore the directory. I also took it to the apple store they were not able to recover it.
I have to say this is extremely distressing, and hard to believe that a simple accident like this could cost the loss of thousands of pictures. I did send it to a rescue company but that was expensive but I think apple needs to do something about this situation.
On Windows there is a way to disable the write cache for external drives. This is not available for Mac OS X. This would prevent this rather common occurrence of a plug accidentally becoming disengaged when the drive is not in the process of writing. This reduces the odds but I still think apple, in order to become clearly superior, needs a better solution.
I know Apple has experimented with ZFS would this not eliminate this possibility of this kind of disaster? Is this in Snow Leopard desktop? I know they are thinking this is a business customer focused technology but clearly if it can eliminate this kind of thing then I think it is extremely useful to their non server customers. Perhaps there are other ways of dealing with this issue but ZFS is designed to deal with these issues. HFS+ is extremely fragile to disk corruption.
I know my situation is not that uncommon and this is not the first time this has happened to me with an external drive. You would think I had learned. I hate to think of how many other people have had the same thing happen to them.
I have a Seagate FreeAgent GoFlex Desk external hard drive, which i've loaded movies, pictures, videos, and documents on to. I have only used up about 100GB of 1.5TB and for some reason when I plugged it in today it wont let me load anything onto it and if you click get info on it, it says you can only read.
I have 2 external hard drives one specifically for mac the other is for either mac or Windows base PC. I backed up on my mac using the time capsule back up now. When I attach to a usb ion my windows PC it wont read or even pick up either external discs, is this normal. How do I get files from my mac to windows based PC, it does work using a memory stick. But why won't PC pick up the drives.
Info: MacBook Pro with Retina display, OS X Mavericks (10.9.4)
I have the PIONEER DVR-104 Drive in my MDD Dual 1Ghz G4 that has stopped reading DVD's. It still reads CD's just fine and will write CD-R's just fine. To get arround the problem (I need to be able to atleast read DVD's) I've installed a plain DVD drive in bay 2. This problem existed before I upgraded to 10.2.4 so it was there under 10.2.3 as well. Toast and the Apple System Profiler recognize it as a DVR-104, the proper drive. Lets see what else can I tell you... We are using Apple branded media. When I do drop a DVD-R in the drive whether blank or written it trys to read it for about 30 sec then spits it back out.
can't write to FTP drives via finder. But I'm having a lot of difficulty connect to FTP drives via finder. Despite using the correct log in details and FTP paths just like I do in Fileziller, Finder constantly rejects and when I do get on using the master file hosting log in details I can't write to the drive only read.
