The drive that disappeared briefly was a native SATA drive connected via SATA, and the optical drives are all IDE running through IDE. In fact, the converted IDE/SATA drives are running beautifully, no problems whatsoever. This is why it was so strange, the optical drives are all IDE now, and the hard drives are all running through SATA now. There should be no connection between the optical drives and the hard drives -- totally separate controllers. Yousuf Khan

I run like that myself and eventually see some problem, usually that I cant have as much stuff open at once as I can just after a reboot. The most recent reboot was because the menus in OE went missing. >>> But there were no warnings in SMART about that drive. >> Because it was nothing to do with the drive, just the OS. > I'd have thought at least some kind of CRC error increment or something. That doesnt see a drive go missing, just sees DMA turned off and PIO used instead.

If the error was entierly with the controller, the drive may never have seen any problem. Arno -- Arno Wagner, Dr. sc. techn., Dipl.

Well, considering that the error showed up with both an IDE and a SATA drive, it may have something to do with the motherboard's disk controller subsystem. It was just something transient, because I just did a warm reboot (i.e. no power-off) and it fixed it. This system is now running Win7 rather than XP, so it might be a driver issue too. Yousuf Khan

Haven't really tried it with the SATA cables, but none of these SATA cables are from the same batch, they were all independently obtained as drives were added. Would the number of drives in the system be a problem here? I got 5 internal hard drives (all SATA), 3 external hard drives (1 eSATA, 2 USB), plus 2 optical drives (all IDE). I got a 650W PSU for it.
