Hitachi 4TB SMART Error – Reallocated Sector Count – Odd Support suggestions.

With my latest build I’ve got my first ever SMART error. The BIOS tells me that the drive must be replaced and makes me go into the BIOS before I can then exit the BIOS and get into Windows. Nothing to do there I don’t think. Once in Windows the Intel RST utility gives me an “At risk (SMART event)” message. So I get the Hitachi DFT utility and it passes the quick test but if I double click on the dive in the DFT list it gives me the SMART info on the drive and there is a red light next to the Reallocated Sector Count with the data: Current 1, Worst 1 and Threshold at 5. Even though when you run the quick test the DFT says something about running a SMART check. So I use the HD Tune program and it gives me more SMART info and shows a Status column with Failed in it and a Data column with the value of 1995. I believe this means that the drive has failed. The Current and Worst counters have dropped from 100 to 1 that is below the Threshold of 5 with 1995 bad sectors but it passes the DFT tests.

When I called Hitachi support I was told a number of odd things. He said that the SMART errors don’t really tell you that the drive is failing and that a Windows Update or incorrect formatting can cause SMART errors, Windows reporting SMART errors can’t be trusted and so on. ??? I tell him that the BIOS and Intel software are reporting the error and SMART errors come from the diver right? He tells me none of that matters and I must run a full test to get an error message for them to see what if anything is wrong. I ask him how long it will take saying it will take like 8 or 9 hours for a 4TB drive. He says only a few hours unless you have old slow hardware. It’s an Intel controller on an X79 motherboard and it took like 10 hours. :(

He also told me they do not cross ship drives. So even if you are lucky enough to find out your drive is failing while under warranty and before the data is lost, you have to go buy a new drive at whatever price to back it up and then get a refurbished drive that you don’t really need.
Anyway, still passes the long and short DFT tests.

Do it oldschool and check it with chkdsk /f /r "driveletter:"

/f - fixes errors on the disk
/r - Locates bad sectors and recovers readable information (implies /f)

I have saved endless amounts of data by using these simple old commands from when the times errors were fixed manually

Probably not gonna work, still worth a try tho
 
really? "do not cross ship drives" so what's the point in then having an RMA service?? i would suggest check to see if yoyr drive is still under warranty and just have it rma'ed :http://www.hgst.com/portal/site/en/support/warranty/

btw. i think the tech support just want you off the line.

As I understand it, after some research, the chkdsk program would only find bad sectors not found by the drive itself. When the drive or SMART routines find a sector that is difficult to read or bad it will write that data to a reserve sector on the drive and mark the original bad and no longer use it. As far as the OS or chkdsk or even the DFT scan are concerned everything is fine because the bad sectors have been swapped out for good ones. So my drive has had too many and the Reallocated Sector Count is now marked as failed as it has passed Hitachi’s own Threshold. If there had been only a few then they would be logged in the SMART info but if the count has not passed the Threshold then you don’t get warning by the BIOS or any other piece of software that is monitoring the SMART info from the drives. As far as I know the data is still ok but no one can tell me how many a reserve sectors are left.

Also, this is the newest drive I have and it’s already passed the Reallocated Sector Count Threshold so I think it won’t last much longer.

Yea, I could not believe it. I’ve only had to do it like twice over the years but they have always (if you are willing to give your credit card info) sent out a drive first so you can try to copy the data off. I know this has become the norm for PC components but to me hard drives will always be different in this regard. If they are going to lower warranties and no longer cross ship then the price needs to drop by half so you can buy a backup drive to keep on hand when one goes bad. I know they don’t want to deal with folks that don’t send drives back or the security issues of taking someone’s credit card info but hay, I’d like to get paid at my job while not having to do it too.

That first guy did seem new. Even told me that I’d have to format the drive and that was the only way to fix the error. I don’t think there is any way for the average Joe to reset SMART errors or the log. Maybe some tool that flash the drives internal software.

I did tell them what the error was but they did not seem to know what it was and just wanted me to run the long test. The problem that I have now is they say the long test is definitive but I disagree. Why is there a SMART event or alarm that the long test ignores? Part of the progress shows it running a SMART test but it should not pass a long test or SMART test with an active SMART event or alarm. It’s kind of an important one too. By Hitachi’s own standard or the SMART Threshold the drive has/is racking up too many bad sectors and will run out of spares. They were trying to say that you can only RMA if the long test fails.

Oh and another fun thing about their support and or site. When you try to check the warranty status you don’t use the full Serial number reported by any software in the SMART info. I asked why my serial number was coming up as unknown and he knew what was up right away. You must use the last 8 characters of the serial number. He said of course (like don’t be dumb) that is not what is on the drives label. I said: So everyone is to pull apart their systems just to check serial numbers? He had no response. Hitachi can’t note this on their site or just have the database query disregard the first few characters when someone enters more than 8?
