Read all this before doing anything.
You select the library in the Finder and right click it and do Show Package Contents. That will revel the inside of the library You would then copy the files/folders out to the other drive MAKING SURE you copy them so that they are in the same relation to each other as they are in the original.
On the destination drive create a new empty Aperture library. You'll probably have the easiest time of it if you have two finder windows open, one on the original library and on on the destination. Revel Package contents on both libraries and then copy from the source to the destination replacing the items in the destination library with items from the source. Make sure you go from source (old) to destination (new). It sounds silly to emphasis this but once you start copying it will be easy to get disoriented and go in the wrong direction. Do something to make sure the source Finder window stands out from the destination Finder window.
I wouldn't worry about copying the previews or thumbnails those will be recreated when Aperture opens the new library BUT don't do anything with the Dobro or previews until you are sure the new library opens. In a worst case scenario you could retrieve the previews and still salvage something from your library.
Of course the possibility exists that you will hit the file(s) that are causing the error that is keeping you from doing this in a normal fashion. If so mark the file(s) that are having problems (color label will work well) and continue with the rest of the library. It is possible that the file(s) that won't copy are not of major importance to Aperture and the new library will open anyway. If not then there may be some other way to work around it. By labeling the files you'll at least know what didn;t copy.
That should do it if you're unsure of anything post back before starting.
good luck
Ps. Read this post Re: New iMac, Pegasus & Aperture? from a recent thread on backups and RAID. In it I explain why RAID is not a backup replacement. Once you recover from this you will need to put a true backup procedure in place.

BTW here is OS X's definiiton of an Error -36
Type -36 error (I/O Errors (bummers)
This file is having difficulty while either reading from the drive or writing to the drive. The file
may have been improperly written data to the drive or the hard drive or disk may be damaged.
This is almost always indicative of a media error (hard error on the disk). Sometimes (rarely) it is transient.
Solutions: Try copying the file to another drive. Use a disk recovery software, such as Disk First Aid to examine the disk. You can try rebooting with all extensions off. Once in a while this will allow you to read the data. The file in question should be restored from a backup that was stored on a different disk. Regular backups can reduce the time to recover from this error.
