error messages when tranfering data to thumbdrive

I have a new MacBookPro, 320HD, 2.66GHz Intel Core 2 Duo processor, with Snow Leopard. I have always put my thumb drive into a slot and transferred my data to the desktop so I can work on it. Only with my new computer does the following happen. After working on any files, I drag them back to the thumb drive. I keep getting the following message, "The Finder can't complete the operation because some data can't be read or written. (Error code -36). It will then create a new folder just like the one I'm transferring to the thumb drive, only without any files. I can then transfer single files to the new folder, but only if they aren't in a folder. So anything in a folder will not be transferred until a new folder is written on the thumb drive and then I have to transfer single files until everything has been moved over. Never happened before, hope someone can help.

How old is that drive?
What format is it in?

The new folder is created at the start of the transfer so it does not happen after the error code message.
If you only use that thumbdrive on a Mac, then consider formatting it to OS X Extended, far more stable than FAT.

Try this. Create a folder on the desktop. Open the data folder on the Thumbdrive and drag the contents into the folder on the desktop.
Should be no problem, as usual.
Now open the folder on the desktop and drag the contents onto the folder on the Thumbdrive. You should get a warning about an existing file, say replace and all the files should be transferred.

It's a work around, if it works, until you can reformat the thumbdrive.
They don't last forever.

thumbdrive problem

In reply to: Thumbdrive

Drive isn't over 4 months, it is formatted as FAT32. Tried your suggestion, same thing happened. Even tried another thumbdrive, same thing. Something I did notice, I can drag any file from my Macintosh HD onto the thumbdrive and it will copy to it. Seems like only the files that are on the thumbdrive can't be worked on and then copied back. Also I tried working on the files directly on the thumbdrive. When I hold down the OPTION key and try to drag to another folder the same thing happens. Any other suggestions?

Second Mod's suggestion

In reply to: thumbdrive problem

The same thing happened to me recently, with an 8 GB and a 16 GB drive (made in Switzerland). The problem only occurred with copying folders, not individual files, like in your case. I agree that FAT32 could be the culprit. And it does not happen on a PC. I've read that FAT32 only supports folders no more than 4 GB. After I reformatted the drive to OS X extended, everything went smoothly. Interestingly, copying FROM the thumbdrive always works and is much faster than TO it. I would now only keep the FAT formatting if I need to put it sometimes into a PC. What I did not try was erase and reformat even in FAT32. Maybe it was time...

thumb drive problem

In reply to: Second Mod's suggestion

Thanks for info. but the drive is only 4GB. Also, I have to have the drive formatted as FAT32 since I go back and forth from PC to Mac. I'm trying to contact Apple about the problem. Could it possibly be because of Snow Leopard?

interesting thought

In reply to: thumb drive problem

You might be onto something but I kind of doubt it. Anyway, if you find something from Apple, please share it with us.
