D0 Note 3479 html file

includes VME-Metro traces of an upgraded VBD working with two VRB's! Address and performance discussion as well as programming sequences. Supercedes (obsoletes?) the ongoing VBD/VRB dialogue which has been taken off.

D0 note 3479 shows the VBD working in Central Tracking mode. 

Some Recent D0 Upgrade Notes. html file
Things I learned in the aftermath of a hit by the "explore.exe" (worm). 
1.  Payloads are now serious! 
2.  Don't mount and leave mounted shared volumes! 
     It is a recipe for shooting yourself in the foot: 
     you've (religiously) backed up your files on the server but 
     you always leave your user or project area mounted as native; 
     your machine gets wiped by some nasty virus (worm, trojan ect.) but because 
     you have the server volume mounted you just wiped out your 
     back up as well! 
     DON'T BE LAZY:  if you must mount the volume then UNMOUNT ASAP. 

Obsolete shares suggestions removed as official Fermilab policy supercedes all: http://www.fnal.gov/cd/main/cpolicy.pdfPostscript fileis the official Fermilab computing policy.

3.  NTFS volumes are not as recoverable as FAT volumes.
     Norton Utilities Diskeditor does not work on NTFS volumes and I could find
     nothing equivalent at the time (cerca Dec. 1998).  (Symantec will not
     recover an NTFS volume for you either!)  Since the NTFS clusters are 
     not really chained, once the MFT (Master File Table) entry is mangled the
     clusters are dangling all over the (gigabyte) disk so that searching for the 
     data cluster by cluster is very time consuming even on fast machines.  On a 
     Windows 95 FAT16 volume some files were easily recoverable with Diskedit. 
     The worm set the length field to 0 and the cluster # to 0 but did not 0
     the information in the cluster itself.  (Next time may be different!) 
     If the user knew what was in the file they could recover the data... 
     For *.xls files one must additionally know something about the structure
     of a *.xls file as well.  This was a mean bug as "undeleting" a deleted
     file would be (infinitely) easier. 
DISCLAIMER: above is my experience/opinion only and in no way official.
