Intermittent issues like these are the worst to debug...
Did you perform a Secure Erase of the SSD before the fresh install?
Does running storage benchmarks generate these problems?
One of the things I tried was installing my OS on another hard drive, Secure Erasing the SSD, and then reinstalling the OS back onto the SSD. Still had random hanging under Windows 7.
I tried running several diagnostic/benchmark tools, and none of them generated any sort of error.
If you are overclocking you could try ease up a bit.
You could try test your RAM, I've seen flakey RAM behave like that.
Run the Full DIagnostic Scan from the Intel SSD Toolbox.
Have the same issues with this SSD. Tried to reinstall Windows 7 64 on the SSD but it hangs during the installation. I am using a MSI P6N SLI V2 motherboard. Maybe it is an incompatibility with this chipset?
I have exactly the same problem but I'm running Windows 7 32-bit and I have a WDC WD2500JS-60NBC1 hard drive. The very strange thing is that my system was running perfectly for almost 4 months now. Then after Windows made an auto-update 2 days ago this strange behaviour started. So I thought to recover my system to a previous stage but it didn't help at all. When I do a S.M.A.R.T. check on my disk, the results are all OK. I noticed that as soon as the system is in idle the high activity time of the disk goes down but as soon as there is a small data transfer on the disk it goes up to 100% even the data transfered is as small as a few KB. Using the diagnostic tools of WD didn't help as the test results are all OK. So I assume that there must be a problem with Windows as in my case this problem just started after that Windows update.
At this time I didn't found any solutions yet.
I have had this same problem since i Installed Win 7 Ultimate X64....did all the tests and EVERYTHING came back peachy,but still had freeze ups.Sooooo I took a chance and removed my GeForce 9500gt 1gb ddr2 and replaced it with my 6 yr old 6800gt...everything runs smooth as hell but doesn't have the graghics capabilities for newer games . That's how i solved it.the 9500gt is pooh for windows 7.
I doubt your issue is caused by the SSD. I have exactly the same hangs/freezes and no SSD.
My setup is as follows:
ASUS Rampage II Extreme - no overclocking
Intel Core i7 950
Corsair 12G ram - tests fine witj memtest86++
2 x Western Digital Caviar Black 1TB using RAID1 setup on single partition
I have been dealing with this issue for over a year now. The problem seems to come
and go with various Windows updates. It seems to always run fine for an hour or two
Performance monitor show 100% Disk Activity and disk light is on solid. When the
disk activity drops, the applications become responsive again.
I have read about a deadlock issues in the Intel Matrix Storage driver, but have not
seen any fixes that work.
I have tried vaious versions of the iaStor.sys from 8.8.1009 to the renamed Intel Rapid Storage
driver 10.6.0.1022. The problem still persists.
I suspect the problem is a deadlock condition in the RAID driver.
Has anyone solved this issue.
I am dumping my RAID1 setup to back to non-RAID as the RAID solution has caused more
grief than if the disk crashed and I had to rebuild my system from backups.
It appears Win7 x64 with RAID via the Intel ICH10R is not yet ready for prime time.
