Foxbat Posted August 25, 2013 Share Posted August 25, 2013 I have a Western Digital Caviar Green 500GB WD5000AADS SATA connected to a SYBA SY-VIA6421-3S1P IDE/SATA/eSATA combo PCI (VIA VT6421A) non-RAID controller card. This particular configuration seems to be causing the system to hang, mainly with larger files about 1GB in size. When the system becomes unresponsive, I could hear the head of the drive continually park and unpark indefinitely every 8 to 10 seconds. Examples of when this happens: while watching a video (freezes at random spots every time, never the same position); benchmarking with RoadKil's Disk Speed (freezes at 8KB blocks and 16 KB blocks, does not happen with Crystal Disk Mark, however); and when performing a binary compare (files are verified to be identical through a different connection). Move and copy operations are unaffected, so I was able to load it up with files.System specs:OS: Windows 98SE (RP9, KernelEx, both are unaffected by this problem)CPU: Intel Pentium III 1GHzMemory: 512MBMotherboard: Intel 82815 Motherboard (28-bit LBA BIOS, IAA installed)HDDs connected to motherboard: Maxtor 200GB IDE (128 GiB in use) Western Digital Caviar Blue 160GB IDE (128 GiB in use)AGP and PCI (no conflicts):Video: nVidia Geforce4 Ti 4200 128MBAudio: Creative Labs Sound Blaster Live!

This problem only happens with the Green drive connected to the controller card. It does not happen when connected to a USB to SATA bridge, or connected to another computer. I checked for data corruption; there is none. I've changed ports, and swapped cables with known good ones. I tried it with and without the 1.5Gb/s jumper setting. I've tried smaller partitions without success. The SMART looks as good as it should for a brand new drive. No bad sectors. It passed the WD DLG test.Going further, I examined the major differences that the Green drive had compared to the others. Green drives run at 5200 RPM and have an 8 second head-park feature. RPM is not an issue, but 8 second-head park has been know to cause problems in very limited and specific conditions. As a precaution, I used wdidle3 to disable the head-park just to see if it might alleviate the problem. It did not.Additional testing has shown it to be in good, working order. The only possibility I could come up with is some form of incompatibility with the controller card and Green drives, but I was unable to verify this. Syba support only offered the same basic procedures that I have already performed, unplug this, plug that, etc. In order to eliminate any doubt, I returned the Green drive for a replacement. Once the new drive arrived, it was tested for potential problems. It checks out fine, and when I went to reproduce the problem at hand, the same thing still happens. A month of troubleshooting hasn't brought me any closer to a solution, so I am out of ideas. Link to comment Share on other sites More sharing options...
