HD Problem: Kernel reports bad sector/inode

[jirza at world.std.com (John Irza)]

Hello All,

The trusty (?) hard drive on my Linux Web server (of less than 6
months old) appears to have suffered a hit. The system is still
running but there are a lot of processes waiting for disk access.
(Status="D" on the ps -ax report).

Here is the output from /var/adm/messages:

Jun  6 06:25:23 neptune kernel: hda: read_intr: status=0x59 
     { DriveReady SeekComplete DataRequest Error }
Jun  6 06:25:23 neptune kernel: hda: read_intr: error=0x01 
     { AddrMarkNotFound }, sector=49171, CHS=158/1/32
Jun  6 06:25:23 neptune kernel: harddisk I/O error
Jun  6 06:25:23 neptune kernel: dev 0302, sector 49171
Jun  6 06:25:23 neptune kernel: inode=6124, block=24585

Now what do I do (short of buying a new drive and re-installing everything)?
Can I "edit" the inode or somehow tell the disk controller to ignore the bad
sector/block?  Help!!

Thanks in advance,
