problem/solution to Win7 TRIM SSD issue

    General discussion

  • I have a device that uses the Intel Atom platform (menlow).  The platform has native support for PATA.  Because PATA HDDs are getting harder to come by, the manufacturer implemented a PATA to SATA bridge IC, so now the system uses a SATA drive.

    I have discovered that SSDs with TRIM enabled firmware (i.e. Indilinx, Intel G2) will not boot into Windows 7, and the repair utility cannot find a solution to the problem.  The problem can be pointed to the PATA to SATA bridge...because when the platform had a PATA interface, it had no problem booting to Win7 with TRIM enabled SSDs.

    In a round about way, I was able to resolve the issue. 

    I put my Win7 image onto a HDD.  Since TRIM doesn't matter to HDDs, I was able to boot with no problems. 
    I disabled TRIM in the OS (went to the command shell, entered fsutil behavior set disabledeletenotify 1 ). 
    I then pulled an image from this HDD, and installed it onto the SSD.  The SSD will now boot into Win7!

    Here's my beef.  Why doesn't the built in Win7 repair utility detect this issue, and flip the switch for me?

  • It's not a common error.  Go to the OCZ SSD Forum and you find many, many people that are using SSDs that support TRIM and have Windows 7 installed.  In fact your's is the first post I have seen blaming a combination of Win 7 and TRIM.

    It seems to be an incompatibility with the PATA to SATA bridge IC and TRIM.  Our system uses a 1.8" microSATA drive, so right there my options are limited.  Thus far, the only SSDs w/ TRIM that I've tested are Intel (SSDSA1M080G2GN) and RunCore (RCP-IV-S1832-C) (indilinx barefoot controller).

    We had earlier version of the computer that still had the PATA interface.  I also had a version of the RunCore SSD with a PATAzif interface, and TRIM enabled (both in OS and firmware) and the unit works flawlessly with Win7.

    After they implemented the PATA to SATA bridge circuit, I acquired the Intel G1 SSD.  Works great with Win7, but no TRIM support. 
    Then I acquired the Intel G2 (w/ TRIM).  It will not load Win7. 
    Then I acquired the RunCore SSD, with an early firmware that did not yet have TRIM support.  It would load Win7 with no problem.  I updated the firmware to the first version with TRIM support.  I could no longer load Win7.  I contacted their Tech Support, and they gave me a revised version of that firmware with TRIM disabled.  The drive worked fine again.

    I agree, it's not a common error.  But, it does exist for me!

  • So apparently you have an isolated case.  I seriously doubt Microsoft is going to make this a high priority.  You would need hundreds, if not thousands, of compalints for very similar conditions to get Microsoft interested in investigating this and looking for a soultion.

  • Hi,

    I'm not sure if I have the same issue here; I have a Sony TZ31WN laptop that has a Tosh 1.8" ZIF drive fitted. I purchased a KingSpec 128GB SSD ZIF drive (1.8”) and installed it. The Bios sees the drive and reports the correct size. I set it to the second boot drive, the DVD being the first. Then tried to install windows 7.

    Windows 7 could not see the SSD, so I have been unable to install Windows 7 (double loss).

    KingSpec have no software tools or drivers on their site and Sony just say I have the latest Bios ver.

    I have not seen any other 1.8” SSD drives so I’m stuck !

    Surly Microsoft must know that this problem is out there. I have been searching for a solution for a week now, and have found lots of posts with the SAME looking problem on different Laptops using different SSD drives, so it’s not an isolated case, it’s more like the start of something BIG as more and more people want to upgrade their laptops with SSD drives, making them bigger and faster let alone more robust, and will also want to upgrade to Windows 7 at the same time.

    Can anyone help (please) ?

    Regards

    Thane

    Your issue is not related to the TRIM question.

    Have you checked to see if XP or Vista install media can see the ZIF SSD?  This would help determine whether it is problem with your hardware and possibly a BIOS setting.

    Since your post is not related to the Original Post (OP) you should start your own thread.  It is not considered proper to Hijack someone else's thread.

  • Not an isolated case. There are a lot of problems with the SSD and the trim function in Windows 7. I think only expensives (very expensives like intel) works well under Windows 7. I`ve got an HP2710p with Windows 7 Ultimate and the drive is a RunCore PATA ZIF Pro IV 128GB. With the 1819 Firmware all the times I've deleted a file bigger than 1GB the light from the disk became solid and the only way it's a hard reset via the power on button. And with this firmware the garbage collection doesn't work at all. Now with the new firmware 1916 it recovers the speed (repair the garbage collection) but it still fails to interact with the trim command implemented in windows 7. So maybe if there will be more communication between hardware makers and OS developers maybe things work well.

  • I currently have SSDs in 3 different systems running Win 7.  None of them are "expensive" and they all perform and function properly in Win 7.  So, it's NOT a problem across the board!

  • I just upgraded the firmware in my OCZ Vertex from 1.3 (no Trim support), to 1.4(Trim) and then 1.5(Trim). I have the exact same problem as articulated in "L u i s" post. On large file deletes the disk activity light comes on and stays on and you can do nothing with the computer while the light is on. It (Trim, apparently) is slower than molasses. I will be checking the OCZ forums to see if I can't downgrade the firmware.

  • Hi!

    I have the same drive, only a 2.5 and I haven't had any problem with it. First I used the bios and changed it to raid, then after the "OS" booted I installed "Standard AHCI 1.0 drivers" in device manager then I restarted and changed the bios back to AHCI and sata, and re-booted, it works fine...

    Oh; I also changed my "paging file" to a regular HHD WD sata drive to keep down on the wrights to the drive, so it will last longer...hope this helps, rember is good, but can not do ever thing for us, "You have to be smarter than the pice of equipment your working with"

  • It has been confirmed that the JM20330 chip in the HDD adapter has problems about trim.
    see this link http://forum.notebookreview.com/hardware-components-aftermarket-upgrades/356421-those-slow-1-8-pata-drives-wanting-sata-11.html
    So if there is any options to turn off trim at the install step of window 7? Otherwise it will need two disk to install windows.
    Or does Windows 8 has this option?

    We just want an option to turn trim!!!

    you can turn on AHCI Through bios before installing windows or if you already installed the windows you can do it Through windows!

    1. Exit all Windows-based programs.

    2. Click Start, type regedit in the Start Search box, and then press ENTER.

    3. If you receive the User Account Control dialog box, click Continue.

    4. Locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci

    5. In the right pane, right-click Start in the Name column, and then click Modify.

    6. In the Value data box, type 0, and then click OK.

    7. On the File menu, click Exit to close Registry Editor and restart the PC!

    And about trim:

    In the Elevated command Prompt windows, type the following:

    fsutil behavior set disabledeletenotify 0

    how to check if TRIM in win 7 is working:

    In the Elevated command Prompt windows, type the following:

    fsutil behavior query disabledeletenotify

    Results explained below:
    DisableDeleteNotify = 1 (Windows TRIM commands are disabled)
    DisableDeleteNotify = 0 (Windows TRIM commands are enabled)
