Subject: Re: Linux 2.6.31.6

	As I've had with the last few kernel releases in the 2.6.31.x
series, I'm still having a problem where I'm constantly getting seemingly
random I/O errors in dmesg output for my external usb hard drive. The thing
that worries me is that although my ext4 filesystem is configured to remount
readonly when problems occur, it is not in fact doing so. Does this mean the
error is transient, worked around, and I can ignore it, or ... what?

Specifically it is these messages I'm recieving whenever I do heavy duty
work with the drive that worries me:

sd 0:0:0:0: [sda] Unhandled error code
sd 0:0:0:0: [sda] Result: hostbyte=0x07 driverbyte=0x00
end_request: I/O error, dev sda, sector 79713943


Note that the sector number is never the same, and has never been the same
over a month's worth of I/O errors, but the unhandled error code result
always stays the same, though that also does not always show up.

In my attempts to determine if there's some sort of filesystem corruption
going on I haven't been able to find any problems - files that were changed
while the I/O errors seemed to be being generated are in fact perfect copies
according to md5sum.

I *really* need to know exactly what is going on here. Worst case scenario I
can think of is that the hard drive is going bad, but the symptoms don't
seem to bear that out. I need to know what the error messages - combined
with the the filesystem behavior (NOT remounting readonly) - mean.

I use the usb drive (a 250gb seagate using a rosewill external usb kit) to
backup two 120GB internal maxtors using rsync. These are all IDE hard
drives.

I would appreciate any tips on how I can determine if linux is working
around the problem silently on its own, or not.

The rest of this email includes dmesg output and various filesystem settings
I've set. Note in the dmesg output I plugged in and turned on the drive,
mounted it and poked around a bit, then unmounted it and ran my backup
script (Which e2fsck's it, mounts it, runs rsync to do the actual backup,
then unmounts it when it's done)
