    It will take a few days to see if there is any change... I'll reply back near the end of the week.

    OK, keep us posted.

    Just so you know, my advice to you is this. Put your OS hard drive on SATAII_0 and your CD/DVD Drive on SATAII_5, with your other storage drives anywhere in the middle.

    My 1TB D:\ and E:\ drives keep disappearing after waking up the system. Not everytime but quite often (maybe 15-25% of the time). All three drives show up as ejectable in the removable devices list.

    I would appreciate any tips or ideas, thanks
    the fix, install intel AHCI drivers. the MS ahci drivers have this apparent bug in them that causes certain hard drives (especially large ones, 1tb+) to be disconnected upon waking from sleep.

    Because you have the intel x-25m ssd, i suggest the Rapid Storage Technology 9.6
    http://downloadcenter.intel.com/Sear...ntel%C2%AE+RST)

    mentioned from tweaktown ssd article:
    TweakTownÂ’s Solid State Drive Optimization Guide Introduction :: TweakTown

    Update (03/29/2010): Intel has recently released a new driver that allows Windows 7’s TRIM instructions to be passed through the Southbridge. The new driver is labeled "Rapid Storage Technology 9.6" and it can be found here. These drivers are also able to pass TRIM commands to RAID 0 and RAID 1 arrays.
    My early testing with the new RST 9.6 driver shows that the drive is much faster than the Microsoft Windows 7 AHCI driver whilst also being just as stable. Testing has also shown a significant performance increase in many real world tests with a significant boost in the 4K range.
    So you might as well upgrade anyways as now it supports TRIM, even in RAID 0 and RAID 1 arrays.

    I just got in a WD 2tb and had the same problem with the msachi driver, updated to the driver above and it seems fine now.

    It happened again so the bios did not fix the issue. I will change the ports. I guess I could also go back to IDE mode. Apparently AHCI mode is not necessarily the best thing.

    Ranova, thanks for the tip about the MS AHCI driver, that sounds promising but I'm a bit leary of Intel's drivers after the problems they had a few years back with their accelerator/matrix drivers. I'll probably try that this weekend.

    I would not use IDE mode, especially that you have an intel SSD. It wont pass TRIM commands with IDE mode, it requires AHCI or for you to manaully do the cleanup...

    After a week of using the Intel driver and sleeping my desktop every night, my 2tb WD has not disappeared. When I was using the MSAHCI driver, it would disappear 100% of the time after waking up from sleep. So it is a working solution, and seems to have zero downsides (SSD speeds are still great using AS SSD Benchmark) - even Tweaktown's SSD article seemed to recommend it.

    Intel drivers are fine, and suggested to be used now for SSD/TRIM.

    You seemed to be all good now then right?

    Apparently that article of IDE vs. AHCI was not well done and PCPerspective did a writeup on what was wrong with the testing and conclusion. After that, BenchmarkReviews pulled the article and put up another one which had a different conclusion (basically AHCI is recommended).

    But they did disagree with your belief that TRIM would be passed only in AHCI (see last page of review).

    I'll reply back on monday after switching the ports around and testing the Intel driver... Thanks

    I have rearranged the ports and installed the Intel RST 9.6 driver as suggested. Everything appears to be working now and the 2nd/3rd drives are no longer disappearing and are not listed as removeable which is another improvement over the Microsoft drivers. Thanks for all the help ranova and warren300.
