Unwanted/unknown file in external HD

Hello everyone,

Not sure if this is the correct forum to ask this, but since it only started when I upgraded to Mavericks, I thought that it might have something to do with it.

So, I have G-Drive Mini external hard drive, and now, among the folders I have in it, there's a folder named System, with the following path: System/Library/Caches/com.apple.kext.caches/Startup (this last folder is empty), and no matter how many times I delete it, it automatically recreates itself.

Do you know what this is and how I can remove it for good?


Thanks a lot 😉

Rui

Ok, so there's definitely something going on. I'm sending the log report from the moment tried to delete the folder from the drive. Here are the steps in order:


1. deleted the folder

2. empty the trash

3. eject the drive

4. switch the drive back on

5. delete the folder again

6. empty the trash again

Hi,

same issue here - very strange.

I put the following in the - possibly related - post https://discussions.apple.com/thread/4934668:


Some weeks ago, I installed an SSD as the boot disk, moving my "old" HDD to the Superdrive bay.

This worked quite well. I then upgraded to Mavericks (from ML).


It's tough to say for certain, but my impression is that since I upgraded, things have gone quite awry.


I'm seeing these Error 107 messages from kextcache as well, repeating over and over periodically. What is very odd is this: the cache is trying to update on the HDD! I checked; there is a Library and a System directory in the HHD's root.


I figured I had forgotten to clear those out when I changed the HDD to be a data-only drive, and that Mavericks was using the System directory on the HDD because - well - it was there. So I deleted both the Library and System directories and rebooted.


This fixed Pathfinder's lockup error (after updating), but - much to my surprise - the System directory is back!


All it contains is a Library directory and that only has a Caches directory in it, which - no surprise - contains the com.apple.kext.caches directory. This subtree belongs to root with group wheel, so that should be ok.


So:

1) why on earth is Mavericks putting this directory on the HDD, and not on the SSD which contains the "real" system directory?


2) why am I getting 107 errors?


I've done the repair permissions bit, no help there, unfortunately.

I've also done a safe restart, but that didn't fix it either.

I just experienced the same with a collegues work mac. The external drive had some remains of a former system on it. Those remains where not visible in Finder but when I opened Terminal and did "cd /Volumes/TheVolumeName" and then a "ls" I saw files and directories like this:


bin

mach_kernel

usr

cores


and so on...


Somehow OSX seems to think the external disk to be a startup volume. Formatting the external disk solved the problem.


[edit]


You may also try to delete all those files and directories, if formatting is not an option. But some of those are quite persistent :-)
