Hi,
Is this drive fubar? It's installed brand-new, and after only three days
of operating it's giving me these errors from time to time.
May 30 07:08:18 web3 kernel: hda: dma_intr: status=0x51 { DriveReady
SeekComplete Error }
May 30 07:08:18 web3 kernel: hda: dma_intr: error=0x40 {
UncorrectableError }, LBAsect=227270012, sector=227270007
May 30 07:08:18 web3 kernel: end_request: I/O error, dev hda, sector
227270007
I could find some other people on the net with these problems, but none
of them happened with brandnew drives.
What can I do?

Seems so, try getting the SMART utils and have a look at the
output of smartctl -a <device>.
However I fail to see why this l-k related and as such offtopic
here.
Servus,

1. I see no particular evidence to suggest that the drive is necessarily faulty.
2. It is on topic because it may well be a coding error in the kernel.

Please post more information. First, what size is the disk?
The LBAsect number suggests an access around 108 Gb. If the disk is smaller
than this, then it would appear that a request was made for a non-existant
sector.
Is the LBAsect number the same in each error? What is the machine doing
when the errors occur?
John.

Here's some more information about the disk from the boot log.
I also found some StatusErrors in there.
May 10 11:14:07 web3 kernel: hda: Maxtor 6Y120P0, ATA DISK drive

DriveStatusError }
May 10 11:14:07 web3 kernel: hda: Write Cache FAILED Flushing!
Thats a different error then what it gives me occasionaly. Googling this
error lead me to believe this is a bug in the ide driver, that my disk
doesnt support some flush command.
After parsing the log with simple script, these sectors seem to give the
errors:
227270012
227270483
236708724
237757036
237757472
238018530

58619448
58619519
58620045
58620048
58620331
I've tried to reproduce these errors by rsyncing the whole filesystem,
executing various find / commands, but nothing triggered them. The
machine is primarily a web server, so my guess is they happen when
apache tries to do something to the disk.
The output from smartctl -a seems a bit large to include in this email.

It is, what kernel are you using?

The that's a known error, you should not worry about it. It's fixed in
later kernels.

I found somewhere that's something wrong with that maxtor drive.
However, everything works fine.

There's nothing wrong with the drive technically, it's just odd (lba48
without FLUSH_CACHE_EXT). It's really a linux ide bug that's fixed in
newer kernels. 2.6.7 will fix your problem.

Wrong.
Bug is a combination of a very minor firmware quirk
and lack of strict checking in Linux IDE driver.
FLUSH_CACHE_EXT bit is set but it is not supported
(but it is not a problem because LBA48 is not supported also).
It is fixed in 2.6.7-rc1 but your IDE barrier patch has this problem
(just reminding you that it is still not fixed in 2.6.7-rc2-mm2).

Ah my bad, I didn't realize this bit was actually set correctly (you
mean (cfs_enable_2 & 0x2400) == 0x2400 is actually true?).

So where's the bug? I don't see it...

Yes but only on unaffected drives. ;-)
0x2000 is FLUSH_CACHE_EXT support
0x0400 is LBA48 support
Affected drives have 0x2000 set incorrectly so we have to check also 0x0400.
(== 0x2400 is needed because & 0x2400 is true if & 0x2000 OR if & 0x0400).
Everything is explained in the patch changelog:
| - many Maxtor disks incorrectly claim CACHE FLUSH EXT command support,
| fix it by checking both CACHE FLUSH EXT command and LBA48 support
| (thanks to Eric D. Mudama for help in fixing this)
and in the patch itself:
+/* some Maxtor disks have bit 13 defined incorrectly so check bit 10 too */
+#define ide_id_has_flush_cache_ext(id) \
+ (((id)->cfs_enable_2 & 0x2400) == 0x2400)

ide_fill_flush_cmd()
+ if (drive->id->cfs_enable_2 & 0x2400)
+ rq->buffer[0] = WIN_FLUSH_CACHE_EXT;

Ok, so I didn't miss anything. Was just wondering because of your

Just checked a fresh copy of 2.6.7-rc2-mm2, and it has it correctly:
static void ide_fill_flush_cmd(ide_drive_t *drive, struct request *rq)
{
char *buf = rq->cmd;
/*
* reuse cdb space for ata command
*/
memset(buf, 0, sizeof(rq->cmd));
rq->flags |= REQ_DRIVE_TASK | REQ_STARTED;
rq->buffer = buf;
rq->buffer[0] = WIN_FLUSH_CACHE;
if (ide_id_has_flush_cache_ext(drive->id))
rq->buffer[0] = WIN_FLUSH_CACHE_EXT;
}
So that's why I didn't follow what you meant, there should be no problem
here. You are reading disk-barrier-ide.patch, barrier-update.patch is
applied on top of that.
So we are back to step 1, why is his drive complaining. I'm guessing it
doesn't have write back caching enabled and aborts the flush on those
grounds - Ed, what is the output of hdparm -i on your booted system?

Hi,

I'm seeing this error too, and also frequent crashes (total lock ups) of the
machine (every day or two at the moment). Could the two be related?
I haven't got round to doing any diagnostics yet, but there's nothing
obvious in the logs. I was going to dismantle the machine and check
connections etc. first.

This is usually also a bad sign, escpecially if the size is caused
by the Error Log Structure areas.
Please send the info of smartctl -v <device>. This should give a
good indication of whether this is a kernel or a drive problem
because it will show some of the internal status of the drive.

The lower ones are definitely within the capacity of the drive. I suspect
it _may_ genuinuely be faulty after all.
Back up your data.
If practical, try overwriting the whole disk, with something like:
dd if=/dev/zero of=/dev/hda
and see if it makes the errors go away.

Hi Rick,

You can use selective self-tests on this drive. You'll need smartmontools
version 5.31 or greater. This will help you pin down the bad LBAs
quickly.

This is a very useful disk feature!

Your disk has already reallocated 15 bad sectors.

There are 13 unreadable disk sectors that the OS has tried to access, and
one additional unreadable disk sector found in an off-line scan.

This is a typical read that failed at LBA 227270007.

See http://smartmontools.sourceforge.net/BadBlockHowTo.txt for info on how
to locate and force reallocation of the bad sectors. When you are done
you should be able to run a long self-test (-t long) with no errors found.
You can use selective self-tests (-t select,M-N) to help locate the bad
sectors.

That is a known issue in older driver versions that should be resolved
now. It only affects our latest generation of drives that are <=
120GB, it will not affect the larger drives (>= 160GB), and it won't
affect any drives of the next product generation because I fixed the
root cause in the drive as well as helping identify a driver
workaround/fix.
error=0x04 is an "abort" and not a critical error
The original note had error=0x40, which is an Uncorrectable ECC
error... that is bad, and you should probably RMA the drive.
You can also try to see if you can "fix" it by writing to that LBA
(obviously backup your data first) and see if the error goes
away... if that is the case, the ECC could have been due to a write
splice at power failure or some other transient event (extreme shock
or heat or something)
If there are a lot of ECC errors (you have them in about 2 places)
which could be a sign of bad things in progress, just RMA the drive.

I use that drive normally, smartctl does not report errors.
That error was not displayed before: I don't remember, but maybe with
the 2.6.5 kernel (is that possible?) - now i run the 2.6.6
