[ILUG-BOM] [OT] Root partition mouting read-only frequently

[Rohit V Bhute]

My partitioning is as follows:
/dev/hda1    /
/dev/hda5    /home
/dev/hda6    swap
/dev/hda7    /data

All are ext3.

The / partition is mounting read-only very frequently, in spite of clean 
shutdowns. As a result, the only apps I can use are Firefox and 
Thunderbird. Anything else (even those two if have to download 
something) requiring access to / (specially /tmp) doesn't work. For 
e.g., running "man" on any command gives "man: can't create a temporary 
filename: Read-only file system".

I looked through the output of dmesg and found the following piece 
interesting.
<cut>
[17180032.820000] hda: dma_intr: status=0x51 { DriveReady SeekComplete 
Error }
[17180032.820000] hda: dma_intr: error=0x40 { UncorrectableError }, 
LBAsect=23677870, sector=23677863

#1470023 contains a hole at offset 0
[17180032.824000] Remounting filesystem read-only
<cut>

The full dmesg output is here <http://rvbhute.org/full_dmesg_error.txt>
Is my disk failing or is it case of partitioning/formatting gone wrong?

Regards.
