smcsw Posted December 26, 2009 Share Posted December 26, 2009 The (free) CrystalDiskInfo tool shows whether TRIM is enabled or not. I upgraded P128 firmware and also use Windows 7. Now the Crystal screen shows TRIM enabled for the SSD. http://crystalmark.info/?lang=en. Link to comment Share on other sites More sharing options...
Lord Farken Posted December 26, 2009 Share Posted December 26, 2009 open the Command Prompt [Ed: run as administrator - Wired] and type fsutil behavior query disabledeletenotify Press Enter you should see one of the following DisableDeleteNotify = 1 (Windows TRIM commands are disabled) DisableDeleteNotify = 0 (Windows TRIM commands are enabled) If Trim is disabled then you need to go back to the Command Prompt and type fsutil behavior set disabledeletenotify 0 Press Enter If you ever need to disable Trim go to the Command Prompt and type fsutil behavior set disabledeletenotify 1 Press Enter Link to comment Share on other sites More sharing options...
Synthohol Posted December 26, 2009 Share Posted December 26, 2009 this should be sticky info if its not already? Link to comment Share on other sites More sharing options...
superj Posted December 26, 2009 Share Posted December 26, 2009 It seems like the only AHCI SATA driver to support TRIM at this point is the default MS driver. The intel Matrix Storage, and Rapid Storage Drivers do not pass the TRIM function from the OS to the drives yet. So even if you have it enabled in the OS and proper SSD firmware you may not get the benefits. Link to comment Share on other sites More sharing options...
ojon838 Posted December 28, 2009 Share Posted December 28, 2009 Not so, superj, ATI (AMD) also has their own AHCI SATA driver. It come with my DFI DVD. Oh, and it supports TRIM according to post #4... Link to comment Share on other sites More sharing options...
purell Posted December 29, 2009 Author Share Posted December 29, 2009 So I restart computer and don't touch it for an hour and the trim process will start? Can I manually run a command at the dos prompt to start the trim process in win 7? Link to comment Share on other sites More sharing options...
Wired Posted December 29, 2009 Share Posted December 29, 2009 No and no. As per one of the stickys (which leads to this MSDN article) In Windows 7, if an SSD reports it supports the Trim attribute of the ATA protocol’s Data Set Management command, the NTFS file system will request the ATA driver to issue the new operation to the device when files are deleted and it is safe to erase the SSD pages backing the files. With this information, an SSD can plan to erase the relevant blocks opportunistically (and lazily) in the hope that subsequent writes will not require a blocking erase operation since erased pages are available for reuse. The "sit and wait" is for garbage collection, which is different than TRIM. Link to comment Share on other sites More sharing options...
trond Posted December 30, 2009 Share Posted December 30, 2009 Not so, superj, ATI (AMD) also has their own AHCI SATA driver. It come with my DFI DVD. Oh, and it supports TRIM according to post #4... The AHCI driver from AMD doesn't support TRIM yet. The only thing the fsutil query in post #4 does, is tell you whether the OS is sending the TRIM command or not. It does NOT tell you if the drive firmware supports TRIM, if the AHCI driver supports TRIM, or if TRIM is actually in effect. You can try that fsutil query on a system that doesn't even have an SSD, and in some cases you'll be told that the TRIM command is sent. Does that mean that the system is taking advantage TRIM? Of course not. Link to comment Share on other sites More sharing options...

trond Posted December 31, 2009 Share Posted December 31, 2009 so my GIGABYTE GA-MA770T-UD3P AM3 doesnt support the TRIM? Your motherboard has no relevance. Every motherboard can run TRIM as long as it supports AHCI. And as already pointed out, the only AHCI driver that currently supports the TRIM command is the one from Microsoft.

Randy Myers Posted December 31, 2009 Share Posted December 31, 2009 what if your motherboard does not have an AHCI setting, which my Asus appears to not have (I can't find one). Will it support trim? Link to comment Share on other sites More sharing options...
