MacBook Pro :: Return Write Access To External Hard Drive?
Mar 26, 2012
My external hard drive was accidentally unplugged without ejecting. Now when I plug it in, it read only. I can copy files from it but not to it. Is there a way to reinstate write access without losing my data?
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.
I have a Late 09 15" MBP and a WD 1TB external HD. I've never had a problem until now. I start up the hard drive, then it loads up fine and the Mac recognizes it just fine. As soon as I try to copy something - doesn't matter how big it is - I get an error and at the end it says "(Error code - 36)". It just says the file cannot be read or written. Weird thing is I can access everything on the hard drive. Anyone have any tips before I try reformatting the HD?
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??
sorry if this is a noob question, but when I try to save things to my new external hard drive a box comes up telling me that the disk is write-protected. Is there a way I can write-enable it? I have tried a bit of searching on Google, but to no avail.
I have a Toshiba 250GB external hard drive to back up pictures. I can write to it just fine. I also have a Fantom Drive 1TB external. I could write to it last week, but I turned it on this week and I can't write to it. I can still pull stuff off of it, but I can't write to it. What can be causing this? I have already installed MacFuse and NTFS-3G. It doesn't make sense to me that I can't write to it all of the sudden.
After a lifetime of owning PC's I finally purchased a MacBook Pro running OS X. I installed Parallels Desktop 5, Windows XP, and several Windows apps to have dual functionality. Now I need to write to my NTFS ext. hard drive where I backup everything. It has 800gb of space left, so it would be a shame to get a new one just b/c I have a Mac now. I first installed MacFuse and then NTFS-3G. Now when I reboot, the ext. HD won't mount at all. What have I done wrong?
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 am trying to access a PC formatted external hard drive, however when I attempt to mount it I get a message saying the drive is not recognized and if I want ti initialize, which i believe if I execute will remove the files I am trying access..Is there a way to access the files on the external hard drive...it is a avi file i need to edit.
Everytime I try to click on my external hard drive it closes the window. I have two identical WD MyBook 250GB drives. Both are FAT 32 formatted. I can access one of them fine from my Macbook. The other displays its icon, but as soon as I click on it, it opens a window, then closes it again. I can access the drive via a PC. I purchased a replacement hard drive (LaCie mobile disk 500GB) which worked fine until I transferred the data at which point the same thing started happening with the new drive.
I ran a Bit Defender scan on the hard drive and the only thing that turned up was an "Exploit.PDF-JS.Gen" file buried inside Adobe Acrobat. Bit Defender couldn't quarantine or disinfect the file so I deleted the copy of Acrobat but the drive still won't mount. I have a Macbook running OS X 10.4.11 and a 2 Ghz Intel processor.
I'm using a 1.42ghz Macmini running 10.4.11. I've been using a Lacie 500 G firewire external hard drive for over a year to store and retrieve files. I have several movies in the mp4 format stored on the Lacie external hard drive. I recently opened one of the movies in full screen (quicktime). It ran for about 10 minutes before freezing up. I watched the spinning beach ball for about 5 minutes. Unable to force quit Quicktime, I pulled the plug on the Macmini. After restarting the computer, the icon for the Lacie external hard drive no longer appeared on the desktop.
I tried several different things to get the icon back, including: repairing the permissions and shutting down the external drive and unplugging the power supply for several minutes before reconnecting the external drive to the computer. The external drive doesn't show up in either the System Profiler or Disk Utilities.
I have a new mac mini and a vista pc on the same network. I want to have my pictures, videos and itunes library on a time capsule so I can access them with my mac and pc. I will not be using time capsule as a backup drive. What I want to know is if I can use an external HD to backup my time capsule content. Would it be better to plug the drive to the capsule with usb or to the mac with fw800? The reason I want a time capsule and not a nas is because time capsule is a router at the same time, which means I save space on my desk and dont have to mess around with different components for my network to work fast.
I have plugged in an external hard drive into my time capsule via the usb input. I have a main router for my network and internet and time capsule is connected to this wirelessly. The external drive doesn't show up as being attached to the time capsule and hence I cannot access any files. What do I need to do to be able to access it?
How do I change permission for writing to my usb harddrive that was previously used on a windows pc. At present it will not let me write and in the top of the window there is a pen which is crossed out.
I have a late 2009 MacBook pro, running the latest version of Lion. Last week, I experienced a Kernel panic at start up, and was unable to launch the OS, even with the recovery boot. Starting in verbose told me that there was a sata issue. I opened the computer, replaced the internal hard drive with lion set upon it, and tried to start again, without any success. I bought a SATA-USB cable to plug my old hard drive. My computer is now running normally, but with the former internal hard drive plugged in USB.
Disk manager sees the new one and I can read data written upon it, but I can't write anything nor erase or partition it. So both the hard drives are OK (I tested them in a friend's MacBook pro and it worked), the computer seems OK too, because I'm running it presently, but any internal hard drive won't work. The cable that links the hard drive to the motherboard does not seem to be damaged, however, the status indicator light is not working since that time.
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 have to return m my Macbook to Apple, and they asked me to erase the hard drive. I booted from disk went into disk utilities select the Macintosh HD and did a 7 pass erase. But it says in the stats (appear at the bottom) that there is still 6 folders, 425 MB space used and 2 files. Should it not say 0? I am unsure if I have done this correctly.
So I may have one of the Seagate hard drives that are failing badly. Haven't heard back from Seagate to see if my drive and firmware is bad, but since I just bought the drive, I'm thinking of returning it.I'm in the middle of a 7 Pass Secure erase on it (1TB). Do people feel comfortable returning a drive after doing that erase? Or should I just forget about it and destroy the drive and chalk it up to a loss?
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..
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.
Starting today, when I try and write anything to my non-OS harddrive (with my music library and data on it), OSX gives me the error: "The data can't be read or written" The permissions seem to be fine. I can open files on the HD fine, but they open a little slow. So basically I only can't write to the drive. What's going on? Is my HD dying?
I've not Time Machine'd in about 3 weeks. After working fine for several months, out of the blue I get this error. I think it was -61? "Get Info" said it was read only. I couldn't figure out how to make it write & read. Now, out of the blue, I can't even mount it.I'm at a loss. My iMac is on it's last legs and I'm playing with fire. I guess the first order of business is to mount the thing but it just does nothing or IDK how to force it to do this?
I want to be able to write to an NTFS-formatted external drive from a Mac (I do not want to create an NTFS partition on my internal drive). I know about the Paragon NTFS For Mac product, but it doesn't get great reviews on CNET or Amazon.
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.
The one response I had was: 'alex try putting your mac os cd in and restart the system holding down the letter d key and let me know what happens.' unfortunately I can't find my system disc... will I need to buy a new one? here's a the problem: I have a PPC G5 iMac 2.1GHz, 1.5GB. The Internal Hard drive is 250GB in total and partitioned into 4 sections. After working fine for ages I suddenly found I can't copy files into one of the partitions. Initially I got an error message saying: "DS_store could not be tead or written. (Error code 36)" I used Disk Utility to clean up the hard drive. Which didn't help. Got a copy of Disk Warrior(4.1) to try a more effective clean up. There were a few errors that found and fixed, but i still got the same error message. Then found a utility called DS_Store Cleaner to try and force it to remake the DS_Store files. This got rd of the DS_Store message but I'm still left with another error 36 message and still unable to properly copy. The message then said: "The Finder cannot complete the operation because some data in "example file.doc" could not be read or written. (Error code -36).
I have also got hold of a copy of techtool pro (4.6.1) and run everything - basic, intermediate and advance scans. Everything (aside from a few minor errors on other partitions - which it cleared up easily) was fine, that partition showed no errors at all. I didn't do the full tests on the system partition though as I haven't used the e-drive function yet. The problem has been ongoing since late March.Just today I found the same problem in another of my partitions: "The Finder cannot complete the operation because some data in "example file.doc" could not be read or written. (Error code -36).This happens when trying to copy to either of those partitions or trying to save anything to either of them.What might be causing this and what should I do next? with the first partition to have problems I am unable to copy/write any file size (eg KB size files) with the most recent partition I found I could copy a 2.3MB Jpeg. The problem occured when I tried to copy a 680MB .mov file (there was enough space - about 1.8GB)
