Get a -412 Error when coping to an External Drive

Hi, Wildcat, and welcome to Apple Discussions. I confess I did a double-take when I read this:

They said to reformatt the hard drive. So I bought a new Lacie 300 GB External Drive...

Did you ever try reformatting the 200GB drive? What was the result?

What program(s) was (or were) running when you were notified of the error -412? I ask because that isn't an error code used by the Mac OS. Perhaps the code was generated by an application you were running.

Can you reproduce the error at will? If so, restart your Mac with all peripherals except the external HD disconnected from it, and no programs running except whatever you use to copy your files from one drive to another. Does the problem still occur predictably?

Hi Wildcat
Error 412 is a file infecting virus in PCs. Perhaps your eps comes from a PC?
Try top clean the file with an antivirus... The problem is only with one file?
bye

I've tried the 200 GB on another computer with the same results.

What results, exactly? Do you have the same EPS file on the second computer, and find that you can't copy it from that computer onto the external drive, either? Would you please clarify whether it's just one file or more than one file that fails to copy?

What happens when you try to duplicate the EPS file on the same disk where it already resides? Select the file by clicking once on it, then type Command-D. Does it duplicate OK?

Are both of the external drives formatted in Mac OS Extended (HFS+) format?

If you can't make copies of these files even in the same places where they already reside, I'm completely stumped.

Are any of the drives in question shared over a network? If so, turn off sharing for them, then try again.

I too would love to know what a -412 error is.

Whilst trying to copy a CD to an internal HFS+ 30 GB drive (on a grey G3/300 running Mac OS 8.6, using the "Mac OS 8.6 Base" and "8.6 All" configurations via Extensions Manager), I was getting it repeatedly.

Disk First Aid (8.5.5) says there is nothing wrong with the drive. Alsoft's DiskWarrior (3.0.3) also gives it a clean bill of health, but the -412 error still occurs after a directory rebuild.

I moved the HD to my G4, running OS X 10.3.9 and ran Disk Utility on it, which reported no errors. I could copy the CD to the HD via the G4 successfully, using the Sony-badged DVD-ROM drive from the G3 as well (just to confirm it wasn't a device error or media error). I put the HD and reader back into the G3 and try to copy the CD again, I get more -412 errors.

So I fit another HD into the G3, this one a 4 GB Apple-badged Quantum, and installed Mac OS 9.2.2 onto it. I set the 30 GB drive as slave, and tried to copy the CD to the 30 GB drive again. Once again, I got a -412 error.

Anyone with some clues as to what a -412 error is, and what's going on here?

Hello

If my memory serves me, undocumented error -412 is often related to excessive number of comments, that is shown in Finder's Get Info window, in a volume.

I guess that the number of Finder's comments in a volume (under OS9?) may not exceed 65535 (or 32767 ?), because Finder's comment id field in HFS/HFS Plus catalog file data is defined as SInt16.

Anyway, possible work-around methods might be, e.g.,
(1) If you don't need comments, remove items' comments before copying them to problem volume.
(2) If you need comments, create DiskCopy disk image in problem volume and copy items into the mounted image.

* Note.
If you use 'Create Image from Folder…' or 'Create Image from Disk…' menu item of DiskCopy 6.3.3 under OS9.1, it will remove all comments of copied items in the created image. So if you need comments preserved, don't use these menu items. (To the contrary, under OS8.6, the same memu items let you copy items along with their comments)

Hope this may help,
