MacBook Pro :: Cannot Write To External Hard Drive (Error Code 36)
May 10, 2010
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 2TB Western Digital Caviar drive hooked up to my 2006 iMac through a docking bay and USB 2.0. I'm running 10.6.6 and the drive is formatted as Mac OS Extended. It's my media and backup drive and I'm always copying stuff to and from it. All was well and good with the setup and I had no problems for probably 5 or 6 months. Just around Christmas, though, I started getting alerts when trying to copy files over to the drive. Error Code: -50.
Basically, I can still view/read files on the drive and play songs in iTunes, but if I try to rip a CD, iTunes hangs and dies. If I try to copy any file over using the Finder or empty the trash with files from that drive, I get the -50 code and alert. A restart will fix the problem for a little while but then it's back after maybe 30 minutes or so that's obviously not a good long-term solution. This page claims it is an "Error in user parameter list" but I have no idea what that means. I've done a bunch of Googling, but people are saying it's anything from problems with networked NTFS drives (which it's not for me) or that it's a disk permissions issue (no bootable system on the drive).

I was trying to set up my Time Machine to an external hard drive. I didn't continue because it asked to "initialize" the hard drive which I had a lot of important things on.
I have another external hard drive I'd like to use but, my Time Machine has this error code of -43. What is this and how can I use my Time Machine on another external hard drive?

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.

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?

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)

I have a Mac Pro and suddenly it won't copy files from any external drive, or write them either. The drives mount and show up in fiinder, and they start copying, but after about 30 seconds they error out with "The operation can't be completed because an unexpected error occurred (error code 50).
It has done this on two different Mac Pros and 3 different external drives. I don't remember this haqppening before. I have Paragon NTFS running on both Macs and they have worked flawlessly for maqny months but now they won't complete.

I took the advice of people online and created a sparse image file as a way of password protecting folders on my hard drive. Worked well for a while. These days, when I try to add or delete files from that sparse image, I get error 61 code. Why can't I write/delete from that mounted image anymore?

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 did do a search on this problem, but i started a new thread b/c I think i may be having a slightly different issue...please hear me out..I have a Macbook, running Mac OS X Tiger (version 10.4.11). I have had a 500 GB external HD (MyBook) hooked up to it (via USB) for the past 4 months or so, never really had any issues, was always able to transfer files, no problem.However, today i suddenly ran into some serious problems. I tried to transfer some pictures to the external drive and after copying 200 or so files it gave me an error, said a specific file could not be transferred (specifically it said "the Finder could not complete the operation because some data in "IMG_3435.JPG" could not be read or written. Error Code - 36 "). At first I thought maybe that specific file was corrupted or something but i checked it out and it looked fine. So I then I tried transferring another folder of pictures, and then I got the same error right away (after transferring 3 files), for a different file. And now i'm at the point where I can't transfer ANY files to my external HD anymore! (T_T). And it's weird, when i transfer folders, it will transfer the folder itself but not the files.

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??

So i am having a problem with copying files onto my Iomega external HDD. Itunes films, other video files (GoPro format, etc.), music, basically anything that is not text or a picture (for the sake of this post, the movie Taken), begins to transfer and right about at the halfway point the message "The Finder can't complete the operation because some data in "Taken.m4v" can't be read or written. (Error Code -36). I have trie dot_clean and several other solutions that i have read around the web but none of it seems to be working. I suppose it might also help to know that mz external drive is formatted as MS-DOS (FAT32). Strangely, i have gotten 2 files to transfer, an iMovie film that i made myself and one of the films in my itunes library. other than those two files, the only thing i have been able to transfer has been text documents and pictures.

The last couple of times I have woken my MBP up a box has popped up with a big red sign in the middle saying my external hard drive was removed unexpectedly and could have caused loss of data. I know this is not healthy and I would like to stop it doing this as soon as possible. It is connected via firewire 800 and is a western digital 250 gig my book pro if that makes any difference. I close the lid of my laptop with it still on and connected and everything is supposed to sleep. It used to work fine, I would open the lid and everything would wake up and I could do what I was doing before with no error messages and the hard drive would still be mounted on the desktop.

I have a USB 2.0 hard drive that I have been using to back up movie files. It has let me transfer files from my Macbook Pro HD to it hundreds of times without any problems.
I have this .mkv file that keeps giving me an error when I try to transfer it to my external. I get "Sorry, the operation could not be completed because an unexpected error occurred. (Error code 0)".
I have transferred plenty of .mkv files to my external with no problems. All other files work fine when I transfer them. It will let me move my .mkv file around my Macbook Pro's internal hard drive but it won't let me transfer it to the external.

I am trying to copy my aperture 3 library (126GB) to an external hard drive to free up space on my local hard drive.
When it is at the final 1gb of the process I recieve an error message:
"The Finder can’t complete the operation because some data in “Aperture 3 Library” can’t be read or written.
(Error code -36)"
I have repaired the aperture library and repaired permissions and this did not work.

We use iMacs in the mac lab at our college. These are new this year and run leopard with FCP studio. When our students are trying to copy over footage/media from desktop to their ext hard drives they can't and are getting an error code 0 (zero). The imacs are formatted to work within our organizations network system however we aren't login onto that or working through the network when they are using them in the lab.

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.

Ok so I have an 8800 GS imac, 3.06 intel core 2, 4 gigs ram. Running snow lepord. I need to resolve an issue where I can not get into OSX. At first I got error messeges saying my external HDD could not read, now it looks like its my primary drive because when I restarted I got the progress bar under the apple logo, indicating that something is wrong with the OS. The bar when to full 100% but then I got stuck at never ending spinning wheel. I restarted and no more progress bar but still the spining wheel of death. I really dont mind refomrating its just that I had some important text documents and other files that I cant get back without recoving them some how. How to proceed? I held down cmd v or s (i forgot) on startup and got a black screen with several problem statements. One reads the system boot strapper has crashed trace BPT trap.

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 received an Acomdata 2Tb external hard drive today from Amazon and plugged it in. Time Machine popped up and I declined to link the hard drive to it. I went into Disk Utility and chose the new hard drive on the left column and went to erase. I chose Mac OS Extended. I named it and hit erase. It started going, and going..... and going... and a half an hour later I knew something was wrong.
Disk Utility was not responding and I eventually had to Force Quit. Now I cannot format the hard drive. I starts and then it stops with a disk error. I tried to run the First Aid verify and repair and both stopped after a few seconds with an error. What do I do?

This error probably indicates a hardware problem or some system malfunction. I usually try to find out what exactly went wrong to take measures to avoid the repetition of the same problem. Exchanging the HD and restoring the sytem may be the quicker solution, but I would miss an opportunity to reconfigure my system to make it more robust.
The system in question is a MacMini (Model A1347) with Os-X-Server 10.6.7. and 2 physical HDs: HD1 has 2 Partitions, the smaller for the server OS, the larger for the Shares (We use the MacMini only as a file server). HD2 is not used (was kept in reserve for cases like this).
That there may be a problem manifested itself first when the mounting of the shares on HD1 became suddenly slow (within 2-3 days) and eventually failed. I first tried to copy all the files from the shares on HD1 to HD2 before attempting any repair actions. Most of the files copied properly but a few failed with error (-36). Those few can be restored from backups, so there is no data loss. Remains the question, what went wrong?
It may be pure coincidence but just before the File-Server failed there was an attempt to upgrade a 3rd party software on one of the clients (17'' MacBook Pro / OS X 10.6.8) to a newer version. Could be that new version was part of the problem because the data files of this 3rd party software are stored on one of the shares on HD1 and the data file format has been changed between the versions. For obvious reasons I need to make sure that this data file conversion was not the cause of the problem?
1) first check the HD1 with a different tool than DiskUtility (It thinks the HD1 is in perfect shape), TechTool Pro or DiskWarrier comes to my mind, any reason to prefer one over the other?
2) Hopefully those tools can reliably test whether the HD1 is damaged or not. If it is the former the HD1 replacement option is the way to go and there is no more reason the 3rd party software may have been involved. However if HD1 is not damaged I'm left with the uncertainty of what exactly lead to the problem..?
3) Is there any check I should do before I just re-format the HD and re-install the OS and switch back to an earlier version of the 3rd party software to be on the safe side?
