当我连接 e-sata 或 usb 作为外部磁盘时,显示屏显示以下消息:
[534.032718] ata3: exception Emask 0x10 ASct 0x0 Serr 0x5840000 action 0xe frozen [534.033063] ata3: irq_stat 0x00000040,connection status changed [534.033403] ata3: SError: { CommWake LinkSeq TrStaTrns DevExch }

**fdisk 可以找到外部磁盘,我使用 parted 设置。但使用 mount disk 时,显示以下消息:
message,can't mount disk**
[873.367903] EXT3-fs error (device sdb1): ext3_check_descriptors:Block bitmap for group 320 not in group (block 540385280)!

我不确定,但也许您在 3TB 驱动器的 4K 块方面遇到了问题。应该是可能的。我的存储中有很多 3TB 驱动器,运行旧的 debian squeeze,但内核为 3.4.8,我很快就会升级到 ubuntu 12.04 lts。
我查看了 ext3 src 并在(http://lxr.free-electrons.com/source/fs/ext3/super.c):
/* Called at mount-time, super-block is locked */
static int ext3_check_descriptors(struct super_block *sb)
所以你的 ubuntu 无法读取 4K 设备。看这里:http://lwn.net/Articles/377895/
