Hi, folks!
Recently I have been granted with external usb-drive. It's 3TB FA
GoFlex Desk of Seagate:
http://www.seagate.com/www/en-us/products/external/external-hard-drive/de...
I've formatted it as ext4 and plugged into machine running F 15. I use
it as apache server directory and as mysql data directory (this
computer serves as internal testing server for web-developers).
Everything works perfect except that I see a lot of errors in dmesg output:
[198659.222949] EXT4-fs error (device sdb1): ext4_find_entry:933:

What's wrong with it? Should I test it somehow? Is it broken and must
be replaced?
Another question here. Could anyone suggest how to prevent disk from
going into sleep mode? When it sits by weekends without work it stops
and after that it takes a few minutes to start it again. By the way, I
put following to /etc/fstab in order drive to be mounted during boot
process:
UUID=632ce2dc-97e5-47ed-9ddf-2217f136e637 /srv ext4 defaults 1 2

Well, yes. Fortunately you can configure sleep time-out using hdparm
or even turn off power management completely. See man hdparm. I also
find wikipedia page on hdparm very useful. Here it is:
http://en.wikipedia.org/wiki/Hdparm
I also find I'm getting errors. The drive can be heard clacking away
*trying* to read, some files sometimes. And I'm also wondering whether
it falls asleep before any drive changes get committed.
If in doubt use sync ;- )

I have a seagate drive that falls asleep when it gets bored. Sometimes
it's quick to wake up (a few seconds), other times it takes ages
(minutes), or may not wake up. I'm wondering if it has three different
sleep levels.

I also have a seagate USB drive that, once it goes to sleep, can
take a minute or two to come back to life--long enough that I start
getting i/o errors. OTOH, my cheap old WD usb drive wakes up quickly
and works fine.
I recall there being a bug in some vendor's USB drives a few years ago
that manifested on Linux, but not Windows, where once it had gone to
sleep it was reluctant to revive on Linux. I don't recall which vendor
it was, though.

For what its worth - I had a 2 TB seagate USB - got similar types of
errors - replaced western digital (I have a stack of these I use for
backups)
- no problems at all. I wonder now if the USB chip on some seagtes is
bad - I've only had this with seagate.
My other drives only take a couple of seconds to wake from sleep ...

Have you thought of putting a USB 3.0 card in your system?
I think the drive you describe comes with USB 3.0 connection, right?

Yes, I already have usb 3.0 port. Should I use it instead USB 2.0? Is
it more reliable? I think I'll simply put the drive inside computer
box and connect it directly to eSATA bus. The drive won't move
anywhere.
Thank you JD. Your hints are sharp as lightening ;- )

In that case, I would opt for connecting it to the internal eSATA port.
Try it and let it run (i.e. with transactions) for a while and check
for error messages in /var/log/messages. I think that should solve
your problems, assuming there is absolutely nothing wrong with
the drive itself. Be sure to force fsck first before you mount it.

How is the external drive connected to your system?

Oops! Forgot to mention. It's attached on usb-port. Here's

I have a 1.5TB dirve with external USB2.0 and eSATA
connection ports (on the external box).
I had tried to get it to reamain stable while using it
on USB ports. I kep losing connection with the drive.
USB is inherenly unreliable.
So, I purchased a pcmcia card with 2 eSATA ports,
and connected to the external box vit it's eSATA port.
I have never had any problems ever since.

Well, yes. Fortunately you can configure sleep time-out using hdparm
or even turn off power management completely. See man hdparm. I also
find wikipedia page on hdparm very useful. Here it is:
http://en.wikipedia.org/wiki/Hdparm
Unfortunately, that doesn't seem to work with one of my firewire
connected drives.
# /sbin/hdparm -B255 /dev/sdd
/dev/sdd:
setting Advanced Power Management level to disabled
HDIO_DRIVE_CMD failed: Invalid argument
I'd already used hdparm, years ago, to save my laptop's internal drive
from an early death.
And, smartctl can't be used with either of the USB or firewire external
drives that I have (to check on them). The interface to the drive is
too dumb, or the program isn't programmed to work through those
interfaces.

Well, the trouble is the drive falling asleep at some time that you
didn't notice... ;-) But since the dozing is some time after the last
access, you'd expect that the file system changes would have been
committed before the drive went to sleep.
I'm beginning to have suspicions that suspending the laptop is part of
the equation.
