I am encountering a really weird problem on my WD Caviar Green HDD. Well first of all I have 2 HDDs on my Desktop, one 160GB Seagate holding my Win7 Ultimate x64 and the problematic one, WD 1.5 Caviar Green for storage purpose.
My problem is kinda weird, when I transfer files from my Seagate(C:) to my WD (D:) the speed is good (50-60MB/s). Then the problem arises when I transfer too "many" large files, the transfer speed would go straight down to kilobytes/s. Well after I cancelled the transfer and access my D:, even entering a folder requires loading for like 10 seconds.
Such problem not only arises when I am transferring files to my D:, it seems like my WD can't handle much activities. For instance, last time I installed my game on D: and I would face much lag after playing for some time. When the same game is installed on C: no problem arises.
Does anyone knows what is the problem?
P/S: There was one temporary solution that I used to tried. After the "situation" occurs, I tried to access as many folders on D: as I can and let it load, repeating such actions and giving it some time bring the D: back to speedy transfer. However, large transfers would causes the situation to happen again. Does it have something to do with cache whatsoever?
1First, i would suggest to get a program to display the SMART data of your HDD. It will let us verify that the HDD is healthy, and also inform us about eventual corrupted sector.
Other things that could be useful to add to your post:
The thing is I tried running diagnostic tools from WD performing a "Extended Test" I kinda passed the SMART test. I am using NTFS as it is an internal drive (WD15EADS). – Steven – 2012-10-11T10:34:07.860
I have exactly the same problem with my 1.5TB Caviar Green drive. Transferring a large 4GB file, or multiple 1TB files starts at 80mb/s for a few seconds, then drops to 10mb/s for the remainder of the transfer. Performed a WD diag test and every thing passed. I am suspecting the drive could die at any moment now. – azgolfer – 2012-11-14T15:14:49.327
