I just installed a new WD Green WD20EARS in my system (Linux with latest kernel 2.6.34). When I attempted to query it via smartmontools I got:
# smartctl -a /dev/sdc
smartctl 5.39.1 2010-01-28 r3054 [x86_64-unknown-linux-gnu] (local build)

>> Terminate command early due to bad response to IEC mode page
A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options.
Further, after I partitioned it (single partition starting on sector 2048 to keep everything aligned to the 4k sector size), I couldn’t write an ext4 file system to the drive:
# mkfs.ext4 /dev/sdc1mke2fs 1.41.12 (17-May-2010)Filesystem label=OS type: LinuxBlock size=4096 (log=2)Fragment size=4096 (log=2)Stride=0 blocks, Stripe width=0 blocks122101760 inodes, 488378390 blocks24418919 blocks (5.00%) reserved for the super userFirst data block=0Maximum filesystem blocks=429496729614905 block groups32768 blocks per group, 32768 fragments per group8192 inodes per groupSuperblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000, 7962624, 11239424, 20480000, 23887872, 71663616, 78675968, 102400000, 214990848Writing inode tables: done ext2fs_mkdir: Attempt to read block from filesystem resulted in short read while creating root dir
As you can see, it gave this odd “ext2fs_mkdir: Attempt to read block from filesystem resulted in short read while creating root dir” error.
I have since nuked the MBR and partition tables with dd and repeated the process which did not give errors. I have been rsyncing files on to it for the past few hours with no complaints. It seems to be okay but should I be worried about this and should I RMA the drive?
