OS X :: External Hard Drive Error Code (-50) When Copy The Files
Jan 11, 2011
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 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 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).Â
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.

Mac Pro, Mac OS X (10.6.8)

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 just got my first Mac which has Snow Leopard. I've been trying to backup files to an HFS+ extended formatted hard drive. This usually fails because there are files that give me an error code of -41. It's random files. I also believe this is affecting why Time Machine can't backup my filesAnyway I can't find a solution to the -41 error code issue.

I'm trying to copy some music files from my mac pro hard drive to a ReadyNAS, which is using AFP file protocol. I can copy the files one at a time, but if I try to copy many of them at once I get the error code -50 message.

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 had both my MacBook and external hard drive for over three years now, and have never had a problem. In the last week, my external hard drive stopped letting me copy files onto it. When you try to drag and drop it just comes up with the blocked symbol. I have tested this with other hard drives as well and keep getting the same error. I've read other forums where it seems the answer is just to reformat the hard drive to the correct format, but I've never had a problem before so it seems strange that the format would just suddenly change.Â

I have a 38gb iMovie file on my MacBook. I also have a 160gb external HDD. I want to copy the file across, sounds simple right? It will start copying happily but when it gets to about 8-10gb I get this error message (EVERY TIME!): Sorry, the operation could not be completed because an unexpected error has occurred (Error code -1309). I really do not want to delete this file as it is a wedding video I did for a friend only a few months ago. I am trying to copy across to a Freecom II drive using USB.

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?

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.Â
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). Â
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? Â
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?Â
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..?Â
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? Â

I've created an ISO file which I need to back up and keep safe. I have a couple on my macbook pro but due to the large file size, it's taking up alot of space on my hard drive. I tried to drag and drop this onto my external hard drive but when I attempted to move them, it came back with an error message saying it wasn't possible to do due to an error. I can drag and drop every other type of file but for some reason this wont want to work?
Note: The file itself ranges from 4.9GB - 8GB and I have about 200GB space on my portable hard drive.

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)

with cloning/copying the content one an external hard drive onto a new external hard drive. Basically, I have a 500GB FW400 drive which I use to store my media files. It's full, so I purchased a 1TB FW800 drive to replace it. Obviously, I thought I could simply copy and paste the media files from the old drive to the new one.I cannot copy the media files to my internal drive first as my internal drive is only 250GB and nearly full itself.I have used Disk Utility to attempt to close the old drive to the new drive, but keep getting "insufficient space" errors.

I have my library on my iMac running Snow Leopard and iPhoto 09. I want to copy it to my MacBook Pro running the same. Whenever I try to copy it over, I get the following error after it copies a few MB worth:
The Finder can't complete the operation because some data in "iPhoto Library" can't be read or written. (Error code -36)
I have found a similar problem online that someone was having, but it was error code -30, and they didn't have a fix.

Probably a stupid question but I can't figure this out as it is not covered in the User's Guide or in the FAQs on the Fantom website. I have an PowerMac G4 with an old Fantom 120GB external drive which is nearly full. I have purchased a Fantom Drive High Speed USB 2.0 (750GB.) How do I transfer data from my old Fantom to the new one?

Macbook pro 13' running 10.5.8 has intermittent issues with usb 2.0 mass storage drives but not jump drives. Here is the issue, my gf just got a brand new mac book pro 13'. This is great for her no more asking to use my unibody macbook. She plugs in the drive I have used for a very long time with my mac my pac etc. with not a hint of issue. The drive shows up copy's stuff off ok. However when it came time to return the data back to the drive it gets about 10% through and just hangs. Here is what I have done. I first thought ok might need a reboot. Then I went with the ok I will check her disk for issues. This is a 3 day old mac book by the way. I found random permissions errors with quick time which has never been run. After the fix the issue goes away for that boot.
The issues seems to come back after a re-boot or so. I go ok enough of this I format the mac with the system disk, then I update to the latest updates from apple. Plug in the drive and still having issues. Run the permissions repair same issues exactly format to format. I have also run the deep test off the system disk the machine checks out through that so I have ruled out ram on her system as a possible culprit. I am at a loss on this machine. I have gone so far as to format the external drive replace the data from my network server and try that. Still no luck. On my box there is no issue it time machines great it copy's data like a usb 2.0 drive should.
