Schnulla Posted August 22, 2009 Share Posted August 22, 2009 We know that the P128 with Firmware-Version VBM18C1Q is able to do some kind of self healing (delete free memory space) on idle times. But what exactly means idle? I read that some people think the system (Windows 7 for example) must be in standby to make the P128 run its self healing? Is that true? Or does the P128 also run this cleanup after some minutes without read or write access? If that is true, I guess the drive will never run the cleanup because windows or installed programs always do some disk access in the background... for example logging, indexing or whatever... Or how is the start of this automatic self healing triggered? :confused: For me it is not transparent but I want to be sure it is triggered ;) Please enlighten me! Thanks a lot!

Corsair Employees Bluebeard Posted August 24, 2009 Corsair Employees Share Posted August 24, 2009 All you need to do is cold-boot your system (no reset - shut it down completely and reboot) and leave it idle (which means don´t do anything with it) for one hour. Windowas or any other backup programms actually won´t have any negative effect here at all. Link to comment Share on other sites More sharing options...
gazman2k3 Posted August 24, 2009 Share Posted August 24, 2009 Does anyone know how I can find out if my P128 drive has the Firmware-Version VBM18C1Q is there a program I need to use to find out. Link to comment Share on other sites More sharing options...

Schnulla Posted August 24, 2009 Author Share Posted August 24, 2009 Windowas or any other backup programms actually won´t have any negative effect here at all. Ok so I guess the cleaning starts if the disk usage is very low ignoring all the logging stuff which windows does in the background. I ask that because in Windows 7 Performance Monitor there is ALWAYS read/write access to folders like: C:\Windows\Prefetch\... C:\$Logfile (NTFS Volume Log) C:\$Mft (NTFS Master File Table) ...and more, so if idle would mean there shouldn't be any write/read operations the cleaning would never start. But I understand your post that this is not the meaning of idle in case of our P128. Link to comment Share on other sites More sharing options...
gazman2k3 Posted August 24, 2009 Share Posted August 24, 2009 You can use this one, it's free. Thanks I just installed the program to check my drives firmware and it looks like my firmware is different to the VBM18C1Q mentioned in this thread mine is VBM1801Q I think the last letter is Q or is it a o I can't be sure this is a screenshot of what the program said http://img207.imageshack.us/img207/8237/capturefpu.jpg Because my firmware is different to the one in this thread does that mean my P128 drive does not have the self healing feature.

Corsair Employees Bluebeard Posted August 24, 2009 Corsair Employees Share Posted August 24, 2009 Exactly. Please check out the other P128 firmware related threads here in the forum (e.g. http://forum.corsair.com/v3/showthread.php?t=79679) to get a better overview.

jthrush Posted August 26, 2009 Share Posted August 26, 2009 Is it really necessary to cold-boot to get the drive to self-heal? You mean the drive won't just do that during normal operation when idle? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted August 27, 2009 Corsair Employees Share Posted August 27, 2009 That is the method to get the drive to start the procedure, but it is my understanding that when the system is idle for more than one hour it will do that in the back ground. I will see if we can get more of an explanation on that feature. But it may take some time. Link to comment Share on other sites More sharing options...

Corsair Employees RAM GUY Posted August 28, 2009 Corsair Employees Share Posted August 28, 2009 There was an article on Tweak Town about this and it is a great read, I have asked for an explanation but I suspect the answers will be basically the same information as posted in that article. Brief Description -When user deletes files in operating system, it deletes only on file system but data itself still remains as invalid. -Therefore drive takes up unnecessary physical blocks of NAND with invalid data, which requires additional operation later. -Maintains the overall performance of SSD similar to the initial condition of SSD. Basic Operation Description -Detects the invalid blocks resulted from the delete operation of file system then secures free blocks which can be utilized for better write performance. Operating Condition -Currently is operated and verified only on Microsoft Windows NTFS system. -Function is initialized only when SSD is powered on after normal power-off/cold boot. Max recovery time is up to 1 hour depending on the state of the drive. Idle state is recommended in between this 1 hour time frame. -SSD cannot be in full disk state condition. We recommend 15% of the drive free. Link to comment Share on other sites More sharing options...
Schnulla Posted August 29, 2009 Author Share Posted August 29, 2009 Idle state is recommended in between this 1 hour time frame. Mhm unfortunately that does not answer my question what exactly idle means considering that windows does a lot of background write operations(logging, recovery, indexing...).

Corsair Employees RAM GUY Posted August 31, 2009 Corsair Employees Share Posted August 31, 2009 The term is open to interpretation but I would expect it to mean for example if you turn the system on and log in to windows and then do not access any applications just let it set idle in Windows. And I would suggest that you have any power management or screen savers turned off. Link to comment Share on other sites More sharing options...
Schnulla Posted September 1, 2009 Author Share Posted September 1, 2009 Is there a tool we can use to check if and when the last cleaning was started? Because this is all very vague to me and I would like to prove the cleaning is triggered :D: Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted September 1, 2009 Corsair Employees Share Posted September 1, 2009 No I am sorry there is no utility, and the proof will be in the use of the drive. Link to comment Share on other sites More sharing options...
Schnulla Posted October 11, 2009 Author Share Posted October 11, 2009 Today I tested if the self healing is really triggered. I did a cold boot and let the PC idle at the Windows 7 login screen. After 1 hour I scanned my drive with Avira Unerase and all deleted files were still there! I was even able to recover them. So it seems the automatic cleanup is not triggered? :sigh!: Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 13, 2009 Corsair Employees Share Posted October 13, 2009 When you deleted the files did you empty the recycled Bin? Link to comment Share on other sites More sharing options...
Schnulla Posted October 13, 2009 Author Share Posted October 13, 2009 Sure. And Avira Unerase not only found my recently deleted files. It found over 8000 files I have deleted in the past. Link to comment Share on other sites More sharing options...
Schnulla Posted October 19, 2009 Author Share Posted October 19, 2009 Can anyone confirm my results? Because now I have a fast P128 which may slow down soon like other low cost SSDs do because there is no TRIM support yet and the praised automatic cell cleanup does not work.

Corsair Employees RAM GUY Posted October 19, 2009 Corsair Employees Share Posted October 19, 2009 What is the firmware version on your drive and what O.S. are you using? Link to comment Share on other sites More sharing options...
Schnulla Posted October 20, 2009 Author Share Posted October 20, 2009 As I wrote before I'm using Windows 7 (the "final" from MSDN). Firmware is the same I mentioned in the first post: VBM18C1Q Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 20, 2009 Corsair Employees Share Posted October 20, 2009 But you are still using the Beta version is that correct? And it has still not been released yet officially and even when it is it will take sometime for these things to settle down, doing anything now would be premature.

Paolo64 Posted October 20, 2009 Share Posted October 20, 2009 Two days till Release of Win7. I hope Corsair/Samsung will give all users of Pxxx the ability to update their old firmware. Many other are also waiting for this moment. Link to comment Share on other sites More sharing options...
