I am using Samba (on top of reiserfs/ext3) in a couple of  
architecture workplaces similar to yours (5-10 users).
No errors like yours are experienced and the only non-standard  
smb.conf settings I use are:

(In the [global] section)
strict locking      = no
socket options  = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192  

In a couple of other places I am using Samba as a media server for  
500meg-2gig file sizes and have experienced no problems there either.
In these situations I am using an underlying XFS file system and the  
majority of tasks are intensive reads rather than read/write.

It would be very strange for Samba to be destroying your disks but I  
can understand file corruption and locking problems because of the  
size and nature of the files (AutoCAD seems to try its best to  
corrupt files on a good day).

I've found most problems like you describe eventually lead their way  
back to a misbehaving RAID card or driver issue.
Either way its not a good position to be in, best of luck and when in  
doubt simplify :-)
