Specifically, I am curious about a particular behavior of the drives after performing a write operation to the disk. It appears that after performing said write, the drive will perform another I/O operation a second or so later, lasting just an instant. (No, I'm not referring to the drive dumping it's cache buffer) Furthermore, if this operation is not performed, due to a system reset or such, no problems are encountered with the drive, save for one peculiarity: The drive will seem to search for something for quite a while upon re-start, then apparently having found it, will boot normally. (This seems to be a common behavior to all Quantums I have encountered) What exactly is this small I/O operation doing? Thanks in advance. --LaMonte "The most original .sig file yet: a non-existant one."-me UUCP: {hplabs!hp-sdd ucsd nosc}!crash!pnet01!lkoop ARPA: crash!pnet01!lkoop@nosc.mil INET: lkoop@pnet01.cts.com
