Default One hard drive much slower for some reason.

Hi folks,

I am in the process of moving my OS from drive to drive and thought I
would test to see which drive is the fastest. I got some strange
results when I tested them One drive is MUCH slower than the others on
the buffered disk reads but I can't see any reason why that would be
so. This is the test results:


smoker-new ~ # hdparm -Tt /dev/hda

/dev/hda:
Timing cached reads: 816 MB in 2.00 seconds = 407.41 MB/sec
Timing buffered disk reads: 172 MB in 3.03 seconds = 56.70 MB/sec
smoker-new ~ # hdparm -Tt /dev/hdb

/dev/hdb:
Timing cached reads: 818 MB in 2.00 seconds = 408.77 MB/sec
Timing buffered disk reads: 38 MB in 3.03 seconds = 12.55 MB/sec
smoker-new ~ # hdparm -Tt /dev/hdc

/dev/hdc:
Timing cached reads: 820 MB in 2.00 seconds = 409.93 MB/sec
Timing buffered disk reads: 170 MB in 3.03 seconds = 56.12 MB/sec
smoker-new ~ #

As you may be able to tell, hdb is really really slow. Well, they are
all pretty slow but that one is a lot slower for some reason. This is
the info from hdparm on each drive: Sorry so long but it may help.


smoker-new ~ # hdparm -I /dev/hda

For the record, hda and hdb are not even mounted. I am currently using
hdc for the OS. The drive used to be a lot faster than this. I used it
for my OS a good while back and recently used it for /var/portage and
/usr/portage. I'm not sure what has changed so I can't figure out why
it is so slow. Anyone see something I am missing? All I see is the
others are udma6 while it is udma5. It has always been that way tho.


Thoughts?

Check dmesg to see if the drives show any differences...

If they are SATA drives check to see if there is a jumper which forces
it into "compatibility" mode, slow mode, something like that...

If they are SATA and you use an intel chipset motherboard check to be
sure that the SATA header of that drive is set to AHCI and not IDE
mode...

Those are just ideas, things I have encountered.

It appears that hdb is using UDMA/100 but it has always done that. It's
a older drive. This drive used to get somewhere in the 40Mb/sec range
tho. I want to say it used to be about 47Mb/sec or so.


All three of those drives are ATA. I have a SATA drive but I didn't
list it since it is working good and fast all things considered. It's
hooked to a PCI card.


Thoughts?

just a quess, did you use 80 or 40 wire ata cable for that disk?

That would be a good call. The slow drive is on the same cable as hda.
It is a 80 wire cable tho. The hdc drive is on the same cable as my DVD
burner which is hdd. Also, I always check to make sure the jumpers are
right too. One is set to master and one to slave. BIOS also reports
the drives correctly as well.


I do have a SATA controller with a 750Gb drive. I wouldn't think it
would affect anything but it is the only change that has been made.


Weird huh? I don't see anything that would cause this either but
something is.


Keep those thoughts coming tho. We need a few more.

Maybe the problem is not external (cabling, jumpers etc), but
internal? Anything interesting in smartctl's report?

I did a test a few weeks ago and it worked fine. It passed and I didn't
see any errors or anything "odd". I did the long test. I actualy ran
it on all the drives, except the DVD of course, and they all passed. I
just thought of something, it keeps those records. Here is the results:

I don't know what else to check. Everything seems to be working but it
is slow as it can get. More ideas I hope.

I was thinking about smartctl -A attributes table (or just plain -a
for all), which might've showed a great number of sector relocations
or other internal I/O-related issues.

But this report raises another question: why aren't the reported
lifetimes in an ascending list? They jump back and forth.

Here is that info. I included all the IDE drives. Sort of see if there
is something different about them.

As for the lifetimes in the report, good question. I think that drives
is doing some weird stuff. It can travel back and forth in time but is
slow for no apparent good reason.
