[SSD]Accidentally Had My SSD Scheduled To Defrag

I had thought Win7 automatically disabled defrag for SSD. Are you sure it was being defragged?

Open up the defrag utility (can just type "Disk Defragmenter" in the search box). The GUI will list every drive you have.

Just remember to re-enable it if you ever put a mechanical HDD on your system.

I wouldn't worry about it, re: "used up write cycles". Wear levelling was in effect the entire time, so unless you let this run for many months, possibly continually (who does that?! :-) ), I wouldn't sweat it.

If you're obsessing over it, you can see if the Crucial m4 supports ATA general log area 0x04 which should contain some indication (calculated internally by the drive) of actual "endurance". Example from an Intel 320-series device:

Device Statistics (GP Log 0x04)
Page Offset Size         Value  Description
  1  =====  =                =  == General Statistics (rev 2) ==
  1  0x008  4               13  Lifetime Power-On Resets
  1  0x010  4             6824  Power-on Hours
  1  0x018  6        989192721  Logical Sectors Written
  1  0x020  6         37887761  Number of Write Commands
  1  0x028  6        118822303  Logical Sectors Read
  1  0x030  6         18340114  Number of Read Commands
  4  =====  =                =  == General Errors Statistics (rev 1) ==
  4  0x008  4                0  Number of Reported Uncorrectable Errors
  4  0x010  4                0  Resets Between Cmd Acceptance and Completion
  6  =====  =                =  == Transport Statistics (rev 1) ==
  6  0x008  4              382  Number of Hardware Resets
  6  0x010  4               61  Number of ASR Events
  6  0x018  4                0  Number of Interface CRC Errors
  7  =====  =                =  == Solid State Device Statistics (rev 1) ==
  7  0x008  1                0  Percentage Used Endurance Indicator
 

Thank you for that info.....I will talk with Crucial on Monday and see how to do the firmware update. I want to make sure that I don't already have the update, and I've never done a firmware update on an SSD.......

However, do you know of a link that explains it all, so I can check if I have the newest firmware, and if not, how to update it?

How do I know if I have a 7mm SSD or a 9.5mm SSD, so I know which firmware update to use on their site? The SSD is in a Sony VAIO laptop.

I found that it is a 9.5mm

I found the firmware, and this is a pretty new laptop, and it says not to use the new firmware update if you have an SAS Expander. I don't know if my laptop has this.

1. computer (the icon)
2. right click on the harddrive, and click Properties
3. look for the "Hardware" tab, and then it will tell you the model number and you could go look it up.

SAS = Serial Attached SCSI (Also applies to SATA).

If You're Unsure, "RTFM"... If You're SURE, "RTFM" Anyway.

Thank you for the link.....I just have to make sure that I don't have an SAS "Expander." I hesitate calling Sony, for I'm not sure I will find out the correct answer. I looked up the Specs and it doesn't mention it. To make sure, I'm going to call Crucial on Monday.

I think another way to see do you have a SAS controller of any thing. Just go to your Device Manager.

run, devmgmt.msc
or right click on the computer icon, on the left click "Device Manager"

Look under "Storage Controllers" if there is SAS

Exp:


There is a very high chance you dont have any SAS.

With SAS:

Thanks to both of you. I do not have an SAS Extender. However, I just read the guide of how to upgrade the firmware, and it is a little complicated for me, so I'm going to still call Crucial tomorrow and have them help me with it.

I successfully updated the firmware for the SSD on my own. It was pretty clear how to do it on Crucial's site. If you need to do it, and have a Crucial SSD, go to »www.crucial.com/support/ssd/inde···urce=web and first click on "Guide" before you start the process. The "Guide" is in many languages.

The only problem I ran into is that you have to download the firmware and then burn a CD with the .iso file on it. I am running Win 7 Pro, and I first made the mistake of just copying the whole file to my CD. It would not, of course, boot up from the CD to install the firware.

I then remembered that you have to use Windows to burn an .iso file to the CD. So I right-clicked on the file, clicked on open, and burned the .iso file. Everything went smooth from then.

Thank you all for your help.
