ERROR CODE -36 (on mac) Solved/Closed

Question

Hello everyone, I have a problem recently with my MacBook Pro, I hope you can help me:

Recently, I have been getting an ERROR CODE -36 message on my Mac when I try to put a file on a USB stick. I’ve already tried three different USB sticks, and the result is the same. The only way that works is copying the folder to my iPod...

Here is the message:

Finder cannot complete the operation because some data in "tp_nadine" cannot be read or written.
(Error code -36)

Knowing that my USB sticks are formatted MS DOS fat 32...

What should I do?

Thank you for providing clear answers ^^

Configuration: Mac OS X / Safari 531.21.10

Hello,

I don't know if this can help you, but here's what Apple says about this error:

Error type -36 (I/O Errors)

The file is encountering reading or writing difficulties on the hard drive. The file
may have been saved incorrectly on the hard drive or the storage medium may be damaged.
This almost always indicates an error on a storage medium (physical error on the disk). Sometimes (rarely), this error is temporary.

Solutions: try copying the file to another disk. Use disk repair software, such as Disk First Aid, to check the disk. You can try restarting with all extensions disabled. Sometimes, this will allow you to read the data. We recommend restoring the file in question from a copy stored on a different disk. Regular backups can reduce the time spent resolving this error.

This article dates back to 2008... And since I'm showing up after the battle...

Good luck!

Hi Try to download iusb family for your system version! You'll need to create an account, it takes 20 seconds, so give it a try.

OK Jebreen :) I'll do that and keep you updated, thanks.

Hello,  I suggest renaming your stubborn file and the folders in the hierarchy leading to it with simple names.  Ritchi

oneniane · Answer

Already, Jebreen IOUSB is asking me for the name of my company or business.. lol
and Ritchi, it doesn't change anything about the folder names... :( snifff

The only way to copy my folder is to copy it onto my iPod, and there it poses no problem.. it only comes from the USB keys :(

Hello,

Here's what I suggest:
- format your USB drive to "Mac OS Extended (Journaled)" (see below) which is the standard format for a Mac.
- make sure you can copy your folders to your drive
- if you need FAT32 because this drive is going to a PC, then format it from your Mac to FAT32, but be careful to choose the FAT32 formatting settings properly (see below).

Mac OS Extended (Journaled) Formatting:
* Launch "Applications / Utilities / Disk Utility"
* Select the "Partition" tab
* Select the USB drive by clicking on the first icon, that is, the one indicating the size of the drive
* Choose "One Partition" (or two or more) for the "Volume Configuration" field (do not leave this field set to "Current" otherwise the other fields remain grayed out)
* Give a name to the future drive
* Choose "MacOS Extended Journaled" for the "Format" field
* Click on "Options" and choose:
- "GUID" for an Intel Mac
- "Apple Partition Map" for a PowerPC Mac
* Start the formatting by clicking on "Apply"

FAT32 Formatting:
* Launch "Applications / Utilities / Disk Utility"
* Select the "Partition" tab
* Select the USB drive (the first icon, that is, the one indicating the size of the drive)
* Choose "One Partition" for the "Volume Configuration" field (do not leave this field set to "Current" otherwise the other fields remain grayed out)
* Give a name to your future drive
* Choose "MS-DOS (FAT)" for the "Format" field
* Click on "Options" and choose "MBR"
* Start the formatting by clicking on "Apply"
Once formatted this way, try transferring your files again

I've had the same problem since the beginning with a Corsair Voyager GT 16Go (a good drive on paper) and my MBPro 15" 3.06 4Go Snow Leopard...

On my wife's MBPro 13" 2.53 4Go Leopard, there’s no problem.

I reformatted the drive to FAT 32 from the MAC (I can't remember if I followed exactly the procedure outlined by Richie, I'll try again) and I consistently have problems, especially when copying large files. With a 3Go file, I get failures sometimes at 1.2Go, sometimes at 2.8, etc.

I renamed the file, made a copy and tried with the copy, I always get error 36 that comes up randomly. The files that fail during copying are not corrupted because they can be read well on a PC or my wife's Mac.

I tested the drive on the MBP 15" 2.8 4Go Snow Leopard and the drive also had issues.

I feel like it’s a bug in the USB driver management on fast drives that causes the drive to disconnect randomly, as if we were unplugging it from the socket. It disappears from Finder and reappears, but the reading fails.

The problem only appears during reading, never during writing, which makes me think it’s an issue related to the transfer speed and especially the sustained throughput. Maybe the Mac imposes too high a transfer speed at some point, causing the drive to crash???

I have the same problem for a few days; my MacBook shows this error "code-36" when I try to copy certain files to certain USB drives/external hard drives. On the same drive, I can put files, and others create an error. The same file can cause an error on one drive but not on another. My MacBook is 3 years old; this is the first time this problem has occurred, and I have been using these USB drives for several months/years without any issues.

Additionally, once the Finder window displays the error, I have to restart Finder because it freezes, and I cannot close the error window.

I'm worried that this might be a problem with my Mac that is starting to age.

I would also like to mention another problem. For a week now, as soon as I launch Safari, it shuts down automatically, making it impossible to go online. I reinstalled Safari without any change.

Without internet and the inability to put files on my USB drive, I am starting to despair!!!
