ESATA box doesn't work??

I've bought an ESATA + USB disk dock by Sedna
http://www.sednacomputer.com/products/se-ehd-03.html

and it does not work with my desktop PC
( Gigabyte GA-G33M-S2H board with built-in ESATA connector, XP SP3).

It works almost well with a new Dell laptop which also
has a buil-in ESATA port.
( However, even in the laptop, the disk is detected only
after manually scanning for new devices in dev. manager)

With the desktop, the ext. disk is detected - also
after manually scanning for new devices in dev. manager -
but then it does not show up in the disk manager, and
several seconds later disappears from device manager.

Two internal SATA disks in this machine work well.
I have not installed any special SATA drivers besides of the
mobo drivers package. In BIOS, SATA is set to legacy mode.

So what could be wrong with this mobo?
Any adivce will be appreciated.

What does "Sedna" say?
http://www.sednacomputer.com/support.html

Because before I would assume it was something wrong with equipment you are
having no other trouble with (two different pieces of equipment) - I would
look into what the tech support for the new variable in the equation has to
say based on your experience.

Actually it doesn't sound to me as if there's anything wrong with the
Gigabyte MB with the possible exception of its eSATA port. (And I've yet to
come across a motherboard where its eSATA port was a defective component.
But it's possible, of course). Conceivable you might be dealing with a
defective external SATA dock, no?

You have indicated that there's no device recognition problem affecting your
internally-connected SATA HDDs, right?

Assuming you have a SATA data cable that has the eSATA connector on one end
and a "normal" SATA connector on the other end...
What happens when you connect the device directly to one of the desktop's
motherboard SATA connectors - preferably the one that's being used by your
secondary internal SATA HDD? Same problem?

When you connect the enclosure to the eSATA port on your Dell laptop,
power-on the device and boot, are you indicating there's a device
recognition problem with that laptop? That the device is not recognized
until you "Scan for hardware changes" in Device Manager?

Or are you indicating that this problem *only* arises if the device is *not*
powered-on at bootup, and following the boot you power-on the device? If
it's the latter situation, that's not unusual for an Intel-based system
involving an eSATA (or SATA) external HDD in an XP OS environment.

But (with reference to your desktop machine)...once the drive is detected in
Device Manager there should be no further problem. But you've indicated that
even *after* device recognition in DM, the external SATA HDD "disappears"
from the system, right? And, of course, it's not listed in Disk Management,
right? That's what you're indicating, yes?

Have you tried different HDDs in the enclosure? Both 2 1/2" & 3 1/2"? Same
problem?

Until now I've never heard of this Sedna product. Apparently it's not a
device marketed here in the U.S. Have you consulted the device's
manufacturer about this problem?

Not likely, because the same dock, disk and cable work well
with another computer (the Dell laptop). But I forgot to
mention that the Dell has Vista SP2.

You have indicated that there's no device recognition problem affecting
your internally-connected SATA HDDs, right?

Yes.

Assuming you have a SATA data cable that has the eSATA connector on one
end and a "normal" SATA connector on the other end...

No, the cable is eSATA to eSATA. The GB mobo has eSATA connector.
I don't have eSATA to SATA cables.

When you connect the enclosure to the eSATA port on your Dell laptop,
power-on the device and boot, are you indicating there's a device
recognition problem with that laptop? That the device is not recognized
until you "Scan for hardware changes" in Device Manager?

Right. Neither connection or removal are auto detected.
This is a bit surprising, as the dock spec says "plug and play",
the laptop is new, and it has Vista.
However, after being detected, it works well.

Or are you indicating that this problem *only* arises if the device is
*not* powered-on at bootup, and following the boot you power-on the
device? If it's the latter situation, that's not unusual for an
Intel-based system involving an eSATA (or SATA) external HDD in an XP OS

I tried also to boot the desktop with the eSATA connected.
Same behavior.

But (with reference to your desktop machine)...once the drive is detected

that even *after* device recognition in DM, the external SATA HDD
"disappears" from the system, right? And, of course, it's not listed in

Yes. And lot of disk errors and timeout messages in the eventlog.

Have you tried different HDDs in the enclosure? Both 2 1/2" & 3 1/2"? Same
problem?

Two 3.5" disks: WD 1 TB and older Seagate 160 GB.
Almost same behavior; the new WD stays in dev. manages a bit longer.

Until now I've never heard of this Sedna product. Apparently it's not a
device marketed here in the U.S. Have you consulted the device's
manufacturer about this problem?

Not yet; I'm now suspecting the mobo ESATA port, but you're saying that
it is unlikely to go bad... Will try to find another ESATA disk.

Thanks again and regards,

Have you considered jumpering the SATA drive in the enclosure for
1.5Gbit/sec operation ?

It could be that the Gigabyte signal level on the ESATA port, is only
at SATA levels. Either a shorter cable should be used, or jumper the
drive so that the drive operates at 1.5Gbit/sec. This will not affect
the drive performance, but may improve signal properties between
the enclosure and the Gigabyte desktop.

For hot-plug operation, you may want AHCI mode. But I don't know the
details, about how you'd mix AHCI on some ports, with legacy on others.
It may require running all the ports AHCI, using a different driver, and
so on. A real mess.

If you purchased a separate SATA/ESATA plug-in card, at least the
driver issues would be separated. You could leave the drivers of
the existing internal hard drives in place, and install a separate
driver for the ESATA card.

The eSATA port is most likely on an auxilliary controller, usually
from JMicron or Marvell. Are you sure this is enabled in BIOS?
If your eSATA drive is in AHCI mode you can usually hot plug
it, but if it's in compatibility (IDE) mode, the external drive will
need to be connected and powered on before starting XP,
otherwise it will not be recognized.

Any adivce will be appreciated.

Actually it doesn't sound to me as if there's anything wrong with the
Gigabyte MB with the possible exception of its eSATA port. (And I've yet
to come across a motherboard where its eSATA port was a defective
component. But it's possible, of course). Conceivable you might be
dealing with a defective external SATA dock, no?


"Pavel A." wrote
Not likely, because the same dock, disk and cable work well
with another computer (the Dell laptop). But I forgot to
mention that the Dell has Vista SP2.

You have indicated that there's no device recognition problem affecting

"Pavel A." wrote
Yes.

No, the cable is eSATA to eSATA. The GB mobo has eSATA connector.
I don't have eSATA to SATA cables.

When you connect the enclosure to the eSATA port on your Dell laptop,
power-on the device and boot, are you indicating there's a device
recognition problem with that laptop? That the device is not recognized
until you "Scan for hardware changes" in Device Manager?

"Pavel A." wrote
Right. Neither connection or removal are auto detected.
This is a bit surprising, as the dock spec says "plug and play",
the laptop is new, and it has Vista.
However, after being detected, it works well.

Or are you indicating that this problem *only* arises if the device is

environment.

I tried also to boot the desktop with the eSATA connected.
Same behavior.

"Pavel A." wrote
Yes. And lot of disk errors and timeout messages in the eventlog.

Have you tried different HDDs in the enclosure? Both 2 1/2" & 3 1/2"?

Two 3.5" disks: WD 1 TB and older Seagate 160 GB.
Almost same behavior; the new WD stays in dev. manages a bit longer.

Pavel...
It's hard to escape the conclusion that it's the SATA dock that's the
problem. It's surely worth exploring with the device's manufacturer.

While like anything else involving a PC component it's possible that the
motherboard's eSATA port is defective and that's causing the problem(s)
you're experiencing. The reason I'm doubtful about that is because I'm
hard-pressed to think of a single incident where I experienced a defective
motherboard's eSATA port (as the *only* defect involving a particular
motherboard), and I've worked with a fair number of MBs equipped with that
type of port.

I realize the SATA data cable that was included with your SATA dock would
obviously have eSATA connectors on each end of the cable, but I was hoping
you had available a SATA-eSATA data cable which would allow you to bypass
the motherboard's eSATA port & *directly* connect the dock to one of the
motherboard's SATA connectors. So you could diagnose whether the problem
was, in fact, with the motherboard's eSATA port.

I don't understand your final comment re "Will try to find another ESATA
disk."

Incidentally, I've worked with two different models of that type of external
SATA dock (apparently similar to your Sedna product) - a Thermaltake &
Vantec, both of which performed flawlessly.

With the desktop, the ext. disk is detected - also

Two internal SATA disks in this machine work well.
I have not installed any special SATA drivers besides of the

So what could be wrong with this mobo?

I have discovered several eSATA drives that do not appear to work with PCs.
The problem in each case was that the connector in the drive was behind a
piece of plastic trim that prevented the plug on the end of my cable from
entering the connector fully enough to actually make contact.

I can only assume that there are some different designs of connector around.
In my case the problem was resolved by cutting away some of the plastic
surround on the connector allowing the connector to enter fully.
