I wanna know if something is normal or a problem and what i can do about it.
I have a brand new WD30EZRX that i bought a couple weeks ago.
There seems to be a bad problem with it. The load/unload cycle count is getting very very high.
Look:
Already at 7474 and i did get +3000 in only one day for NO reason.
In comparison my Caviar Black that i use for my OS is only at 200-250 and it has 6 months.
For informations, i use my caviar green for storage and i didn’t copy any files on it these past 3 days, and even so it keeps getting bigger and bigger and bigger load/unload cyles.
If i understood this right, it’s VERY bad cos the disk could die early (the smart infos give 198/198 and will decrease till reaching 0 at this rate in a few months, can’t believe thay).
What’s the problem ? Should i return it ?
I can’t believe i am at near 8000 cycle counts in 3 weeks. Unbelievable.
So, the good news is that WDIDLE works with the WD30EZRX.
I still had some trials and errors and so I’m going to write it all for those who will meet the same problems as me.
1/ You need a bootable USB device.
Do not use SD card reader cos it can cause some error when you try to boot on it in some cases for whatever reason. Prefer the good old USB Key (I used a 250MB sony usb key)
Format it with HP USB STORAGE FORMAT TOOL V2.1.8. To make it bootable, download the WIN98DOS files there : http://files.extremeoverclocking.com/file.php?f=196 and choose the right option in HP USB TOOL (check the last box and search for the right folder where you unzipped the win98dos files)
2/ Turn off your computer and if you have an HDD that doesn’t need to be touched (like a Caviar Black), plug out the power cable from the HDD. On many motherboard like mine, there are 4 SATA 6GB/S. You have to use the FIRST TWO (SATA 0 and 1) and not the other ones since they are detected as External SATA and WDIDLE WILL NOT WORK if you plug your HDD on those (It will report and ERROR CODE 0006 or say it didn’t detect any HDD)
3/ Now here the very important parts. I have a Z68a-GD65 motherboard. To boot on the usb key, you need to enter the BIOS and go to where in show your Hard drive disks in the SETTINGS tab. You need to be in IDE mode (so change from AHCI to IDE. DO REMEMBER TO PUT IT BACK TO AHCI once you’re done.
4/ Boot on your USB key. Type WDIDLE3 /R to see if the tool is recognizing your HDD. If yes, it will report the model and the IDLE3 settings (8 seconds on a WD30EZRX, same as every caviar green), if no, it will report an ERROR CODE. Please read the part (2) carefully to see if you encountered the same problem as me.
5/ Either type WDIDLE3 /D to disable the IDLE3 timer, or type WDIDLE3 /S300 to change the timer to 300 seconds instead of the original 8 seconds. In my case i disabled it.
6/ Do that to each caviar green HDD you have. Then turn off your computer and plug your HDD back if you did what i did. Turn on your pc and REMEMBER to go to the bios to put the AHCI MODE Back.
7/ It should be done (I’m still a bit sad i didn’t see the problem ealier, +7000 cycles is not good )
2/ Yes - accordingly to my experience it is good to connect only one HDD at time - only the one that needs to be upgraded. When I tried to disable timer when there were 3 drives connected (WD1002FAEX, previously upgraded WD20EADS and new one WD30EZRX) disabling timer doesn’t have an effect. I was even convinced that Load/Unload cycles were counting faster than before that first try. Accordingly to my experience HDD don’t need to be connected to SATA 0/1. My HDD was connected to port SATA 2 and everything works fine. I think that you just have ESP option turned on by default in your BIOS, for ports higher than SATA 0/1. I can enable or disable it, so I haven’t got any error while using SATA port 2 as it had ESP turned off.
3/ Yes - boot device needs to be set appropiately. But I didn’t even knew that I need to go to IDE mode. I upgraded my WD30EZRX in AHCI mode and when it was the only one HDD connected to controller everything worked fine. So at least on some systems going IDE isn’t necessary.
4/ , 5/ , 6/ OK, except that I didn’t had to change back to AHCI as I didn’t even disabled it.
My system is GA-890GPA-UD3H Rev2.1
“ESP” is BIOS option that enables ESATA for given SATA port (“ESP” probably menas just “E SATA Port”).
EDIT:
Additionally I haven’t noticed any slow downs of data transfers after either setting timer to 300 s and disabling timer completely. Everything was done as I described above - on SATA port 2 with ESP disabled and in AHCI mode with only one HDD connected to SATA controller. PC was booted from CD-RW with software noted above.
