Seagate 1.5TB for 109.99

Hello all,

I see that tigerdirect.com has the seagate 1.5tb drive for only 109.99
today. That's the best deal by far that I've seen on it to date.

Just wondering, I heard about some issues with this drive from some myth
users a few months back. Have those issues been fixed? Can someone recommend
this drive to me for my main recordings drive?

-Any input is appreciated

-Thanks
-Steve

The issues were about the firmware on the drives at the time. AFAIK all
of those issues have been fixed. The only concern you might have is if
you get a drive that has been sitting on the shelf and hasn't been
updated yet. You can just check when you get the drive.

I don't have the 1.5TB drives, but the 1TB drives are doing just fine
for me.

Have fun!

Re: Seagate 1.5TB for 109.99 [In reply to]

Not the same as MythTV BUT.......

I use 7 of these drives in my Thecus N7700
http://deancollinsblog.blogspot.com/2008/10/thecus-n7700.html

Firmware upgrades HAVE NOT FIXED ALL MY PROBLEMS, including having to
ship back 4 drives to Seagate that were less than 30 days old and they
ship me back 'reconditioned units'.

If you have to then go ahead but if you don't have to then stay away
from Seagate for now until they really fix these problems.

Thanks for the info. I'll be staying away. Maybe this is why they're
offloading them for 109.99.

Mebbe you want to catch them on sale at Frys or BestBuy. That way
if you have problems, you don't have to worry about shipping issues.

I had 1 of 5 from NewEgg be DOA. I bought a couple more from BestBuy
that I've not had troubles with. I haven't put any of them in critical
positions. None are boot drives or recording drives. (lots of bulk storage)

I have a bestbuy near me but do they really have descent sales? I mean
every time I walk into bestbuy stores and look at computer equipment I
end up laughing when I find a 1GB DDR2 dimm for $67 or some other
ridiculous price. The last time I looked at hard drives (less than 1
month ago) a 500GB SATA hard drive was over $100US.

I have had a $50 best buy store credit for over a year. Every time I
go to the best buy down the road to get something with it. I just
can't bring myself to waste the money because it is literally 2x or 3x
more than online. I am just saving it for the day I won't want to wait
and then I will just take the hit.

I second that - I've gotten NO satisfaction when I've received DOA
items from TigerDirect.

I have currently failed 2 of 15 that we have in service in a RAID 6.
The first return selecting the 2 day option (costing $20) took 6 days.
The second time that we failed one, my boss bought another one from
Newegg just so we would have an extra on hand. It arrived the next day
with Free shipping.

All drives were updated to the firmware Seagate says should work before
being put into service.

What are those "issues" or "problems" ?

Running 3x1.5TB here without issues so far (has been a bit over 1 month)

Yes, I completely agree that you will have no end of problems with these
drives. Since you once read somewhere that there were problems with
them, anything that ever happens will be due to the problems with them,
not due to whatever causes the problems.

Wait until Seagate gets a new line of HDD's with an unsullied name.
Until then, buy some $300 WD 2TB HDD's.

(Actually, I'm not recommending the WD's--if you thought so, read again.)

FWIW I have been using a 1.5 TB Seagate drive to store my recordings
since January with-out issue.

I have one at work storing patient reconstructed CT scans before they
go to more permanent storage. No problems so far in 6 months of
usage.

BTW, before everyone tells me I am an idiot for doing this. There is
actually a way to get the raw data back from a different machine so if
this one failed it would not be the end of the world. And on top of
this the system is experimental (non FDA approved).

Hmm. I just ordered two of their 1 TB external drives, thinking they'd
worked out the problems with them. Now I'm wondering whether I should
cancel the order or cross my fingers and hope that I get good ones. They
have a 5-year warranty, but still, an unreliable hard disk isn't all that
useful.

Hi,

Back then, the issue was cache flush commands not completing while streaming data off the drive. This only happend with the drive write cache enabled.

A firmware update that fixed this issue was provided by seagate.

Next there was a 2nd firmware problem: certain drives could be "bricked" when power cycling; also fixed by a firmware update.

At least for me, a final issue remains: I've never had harddrives develop so many relocated sectors in such a short time. I started logging changes when I first noticed the sector counts (about one month after initial install) - they had all started out clean.

Table contains a date column and relocated sector counts for each of my 5 drives:

2009-01-14 01:00:01; 0; 1; 1; 2; 7;
2009-02-12 01:00:01; 0; 1; 1; 2; 20;
2009-03-11 01:00:01; 0; 1; 1; 3; 20;
2009-03-17 01:00:02; 0; 1; 1; 3; 21;
2009-03-18 01:00:01; 0; 1; 1; 4; 21;

So after about 4 Months, 4 out of 5 drives show reallocated sectors;

I've got a 2nd batch of 8 drives at work but they're behind a HP P400 Controller that unfortunately doesn't allow access to the smart data, so no Idea how these are doing. At least ther have been no outright failures.

Yep this is the problem I'm now having still with SD1B firmware.

These firmware updates are not solving the problems and Seagate
whitewashing with PR saying the issue is resolved is just plain false.

I feel cheated I now have 4 out of 7 as 'reconditioned drives' after
wasting a little over $1000 on brand new Seagate product and not being
able to use it for it's intended purposes.

I will second that - I took a chance (after reading about the
problems) and bought one of these disks for my master backend. I
installed it back in December and has not given me any issues as of
yet. It even has the "bad" firmware SD17 (or whatever it is). But I
am not using RAID - just LVM - and it's only holding recordings, not
the DB or system partition. So far I'm happy - YMMV of course.

I suspect that the majority of the drives do actually work, but the
people who are happy with them are not vocal about it (for obvious
reasons). I am even considering taking advantage of this deal and

For the medical research system that I am using this drive since
November I did not mess with the firmware either. Its a windows XP SP3
box and the drive is not used in a raid however.

Seems to me that can only get worse as data densities go up. The same
size surface defect now affects a lot more sectors than it would have in
the past.

I picked up one of these drives (newer firmware line CC I think, not SD)
at Microcenter for 109.99 too and have yet to have a problem with it.
Though I am using it in my Vista game/main machine (that dual-boots OSX
for iphone development) and have yet to have a problem after 3 months.
It is not raided and I haven't really streamed any videos off of it.

Do you guys remember hard drives from 20 years ago? I mean you paid
$700 USA for them and they all came with a list of 100s of bad sectors
standard and as you used them more would be added. You had to
regularly run checkdisk to test your sectors... Things are much better
now and densities are very much higher.

I am not sure this has a any correlation with densities. At work I
have 200+ drives that spin 24/7/365. Some of these are 7 or more years
old and when I look at the number of remapped sectors on any of these
(from 8GB ide drives to 750GB Segate 7200.11 drives) it usually is
less than 20.

Yup, I remember that. There'd be a "defect list" printed on top of the
drive with the C/H/S numbers of the known bad sectors.

Actually, though, drives still have defect lists; it's just that it's
handled internally, now, and they have a certain number of "extra" sectors
that can be used to replace ones that fail. When you get the drive the
known factory defects have already been remapped. New ones that fail as
you use the drive are remapped on the fly and that's what you see in the
SMART data.

I do know about the remapping and the extra sectors however I was
unsure weather or not the remapped sector count actually included the
factory bad sectors or not. Either way it appears drives are much more
reliable now then they were back then.

Wrong whether. At least today I can blame my bad English on the cold
meds I am on since I contracted a really bad sore throat yesterday..

Consider that the number might be bogus. I have 2 seagate 750GB that
claim many PENDING sectors (which should generate read errors), one of
them over 3000...

There are no such sectors. I've dd'ed the whole drive and checked via
mdadm several times. The SMART response is just wrong.
