We are also having the same issue:
I have five identical machines with exactly the same P55-USB3 v2.0 Motherboard. The first "test" machine that I built worked perfectly and still does not give me any problems. However, the four additional machines are ALL causing major headaches. They are all using Western Digital hard drives.
The setup is as follows:
Windows XP Pro SP3
SATA PORT 0 - A single stand alone 160GB Western Digital HD which runs the operating system and ALL applications.
SATA PORT 1 - 2TB Western Digital HD (RAID 1) (Model WD20EARS)
SATA PORT 2 - 2TB Western Digital HD (RAID 1) (Model WD20EARS)
SATA PORT 3 - Stand alone 2TB Western Digital HD (Backup Drive) (Model WD20EARS)
The idea is to have a 2TB RAID 1 drives to store all of our critical customer data. In addition, we've added single stand alone 2TB drive which every night, using a backup program called SyncBack, has all of the data from the 2TB RAID drive copied to the stand alone 2TB "backup" drive as yet another layer of protection against failure.
The data stored on the 2TB RAID is never "in use" is simply data storage. It is never being access from any other computers or any applications.
The problems we are experiencing are as follows:
The 2TB RAID array is constantly going into degraded condition. One of the drives in the array continually shows up as “offline” “failed” “error occurred” We can reset the drive status to normal and it will rebuild the array to 100% and then it will run OK for a day or two until it fails again.
The second issue is that when copying the data to the stand alone 2TB backup drive we consistently get the following error:
{Delayed Write Failed} Windows was unable to save all the data for the file. The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere.
The error log also shows these errors:
1. An error was detected on device \Device\Harddisk2\D during a paging operation.
2. The system failed to flush data to the transaction log. Corruption may occur.
To troubleshoot I’ve already done the following steps:
1. Updated BIOS to latest F9 Version
2. Ran official Western Digital HD Diagnostics in FULL TEST on all hard drives. ( They all passed 100%)
3. Purchased another set of brand new SATA cables
4. Replaced the hard drives with another set of brand new hard drives (Tested them as well 100% OK)
5. Downloaded and installed latest version of Intel Rapid Storage Technology Application
6. Deleted entire RAID array, Deleted all Partitions on HD, Recreated RAID array, Reformatted RAID 1 drive.
7. Performed clean install of the OS from XP Pro Disc
8. Took an EXACT CLONE using ghost of the original working ‘test” computers OS hard drive and used in the problem machines.
9. Replaced the entire motherboard with another brand new one
10. Replaced the memory
11. Replaced the power supply
12. Replaced the CPU
At this point I have no other choice but to feel the problem is with the motherboard itself. Again, I have five machines all identical and only one of the works without issue. These problems are occurring on all four of the other machines. I’ve spent the last three weeks swapping out parts, rebuilding raids, replacing cables, OS’s, etc and still after a day or two the problem resurfaces and drives start going offline and being unable to copy the data to the backup drive.
Any advice you can give will be appreciated.
