i have an wd20ears drive with the Manufacture date of 1 May 2010
The firmware of my drive is 00J2GB0
ii have made several tests of my drive na dsometimes is rather slow like 20.5 ms seek time
is it possible to update to the new firmware 00MVWB0???
i see pictures of benchmarks with the new firmware taht is much better than the older with 14 ms average and 125 MBs to speed and mine is only 107MBs
PLEASE is it possible ??
i dont see any update in downloads on western digital webisite
cheers people

Are you formatting the drive correctly? It needs to be advanced formatted.
yep im using windows 7 in all computers:stuck_out_tongue:
any word of firmware update to the first three platter hard drives

The 00MVWB0 drives are physically different. They have 3 platters vs 4 in the older drives, even though the capacity is the same. (They’re just squeezing more data per platter, etc.)
I’m betting that has something to do with the difference.
With that being said - I really hope they DO release some kind of update to make the drive report it’s sectors natively as 4k. Some Unix filesystems would like that very much.
sometimes the drive transfer rates are realy bad
i cant mantain writing of usb 2.0
normaly i have 22-25 MBs writing in usb 2.0
with older drive usb 2.0 is allways used 100%
According to the spec sheet, the maximum sustained data rate for the WD20EARS is 110 MB/s.
WD Caviar Green Desktop Hard Drives (Jan 2010):http://www.wdc.com/wdproducts/library/SpecSheet/ENG/2879-701229.pdf
If the current version is rated at 125 MB/s, and if it has 3 platters and 6 heads compared with 4 platters and 8 heads for the older version, then we should expect that …
125 / 110 = sqrt (667 / 500) = sqrt (8 / 6)
This is because we would expect the number of bits per track to increase as the square root of the number of bits per square inch.
Using the above assumptions, we get …
110 x sqrt (8 / 6) = 127 MB/s
Here is an interesting thread along the same lines as this one:http://community.wdc.com/t5/Desktop/WD6402AAEX-new-drive-slower-than-older-drive/td-p/37755
The OP was able to confirm that two drives had different media by referring to the 5th character in the DCM (Drive Configuration Matrix).
thanks for the info
the drive has some bugs… nothing that we can do about it until they release firmware
Fixed it successfully by installing
Intel(R) Rapid Storage Technology driver for Intel G33 Chipset
