i wonder what my problem is then ;p cause i was getting alot timeouts, and normally i always turn off disconnect, i've had years of problems with it (since the drive was first written, and this is linux or freebsd) i added this new drive seagate bar. machine was stable before that. I turn ON disconnect for that drive only, and timeouts have gone away. And i do have two other seagates in there, same model, and those don't like disconnect. ( also have two ibm 4 gigs, 3 quantum 4 gigs ) OS is linux 1.3.33 standard, i do think i have bios version 1.25 tho, or maybe thats 3940 uw, i forgot, too many cards. > > > > In the meantime, I found a way to stop the timeouts occure.
