难道我的硬盘快挂了么？

GMT

一台老机器，用testing netinst安装，完毕登录间断出现如下信息：

hda:dma_intr:stat us=0x51 {DriveReady SeekComplete Error}
hda: dma_intr:error=0x84 {DriveStatusError Bad CRC}
ide:failed opcode was unknown
这个搜了一下，说是有坏扇区或数据线的问题，shell基本不能正常使用（总是间断出现这些提示）

现在换了ubuntu8.04,可以正常使用，但dmesg有
ata1.00: status: { DRDY ERR }
ata1.00: error: { ICRC ABRT }
的提示

现在就想问一下如果还可以将就使用的话，如何屏蔽这些信息而不影响正常使用？

dmesg显示如下：
