In Windows 7, my second HD drive, teh 1TB Caviar Black disappears randomly from My Computer/Disk Managment. If I am writing to that drive, the process fails.
I have disabled sleep/power save mode
I have tried with both IDE and AHCI in BIOS
I have swapped SATA cables
I have tried reformatting several times.
I have searched for bad sectors
I have run the WD Data Lifeguard Diagnostic, which reports NO errors.
This hard drive is 1 month old, and has done this since I got it.
Same here. My system disk is SSD on SATA II. I have 2 wd1002faex on SATA III. Both are disappearing randomly or freezes. I installed them on a Marvell 88SE91 adapter (onboard adapter on MSI Big Bang), and did not use RAID, No matter what Marvell-driver I use, problems remain although I must say with the latest Marvell driver 1.0.0.1051 The disks do not dissapear, they only freezes. I’m already searching a month for a solution.
