RHEL4 Oracle 10.2.0.2

I get the below message when I attempt a simple query on our members table:

SQL> select firstname, lastname from members where rownum < 25;
select firstname, lastname from members where rownum < 25
*
ERROR at line 1:
ORA-01115: IO error reading block from file 12 (block # Cool

ORA-27091: unable to queue I/O
ORA-27072: File I/O error
Additional information: 4
Additional information: 7
Additional information: 8192


Here is what is in the alert.log:

ORA-06512: at "SYS.DBMS_SPACE", line 1554

I can perform:

SQL> select count(*) from members;

COUNT(*)
----------
15431

and get a valid response.

The disk is not full. Is this datafile corrupt? I've experienced corrupt datafiles before, but have not seen an error like this.
Thanks.

Anything related in /var/log/messages?
Run dbv against file.
Does dmesg report disk problems?

I checked in /var/log and could not find any related messages.

I also brought this to the attention of our SysAdmin and he found that the disk is question is critically close to failure. I'll have to recover this datafile to another location. Thanks for your help.
