HDD Regen and reallocated sectors

300? Wow.
Well yours is made for speed so maybe it's how it works..... I have no clue really.
On SMART my Samsung has 125, must've been from heavy torrenting I guess.

In my case, external hard drives don't sit on the same table as the user. That's because small "earthquakes" occur when users touch the table or move the mouse. You don't notice it, but the heads floating above the hard drive platters notice it. After all the times you've shaken the hard drives and caused the heads to slap the platter surface, you might get some errors.
A lot of people forget that they it is easy to vibrate or shake an external drive while the heads are moving. It doesn't have the benefit of sitting inside the huge mass of a desktop case that dampens out even the shaking of someone walking by (if your flooring is not on a concrete slab).

HDD Regenerator will not reduce the reallocated sector count - the drive will not let it, once a sector is reallocated, that's it. HDD Regenerator may be able to "fix" a bad sector, but only that, which was not reallocated (the drive produces an error when you try to read it). However, it is safer to let the drive reallocate the sector.

Yup :p

its obviously a bad drive since the other HDDs, even older, are still working fine. RMA or get something else.

Oh, because I participate in a local hardware forum... where all the causes for bad things seems to be always the PSU, or so they keep posting ::)
So when you ask something you have to state beforehand that your PSU is perfectly fine :P
Well, I've already filled the RMA form at WD site. Official WD RMA is handled here by a 3rd party, that from the net side of things at least, looks kinda shady. They don't even have a website for their local activities, and WD doesn't even provide a phone number. I had to get the number from a forum member that uses the RMA regularly for resellers (I need the number to find out when they work, so I can take them drives). At least for him he always got new ones. Let's see how I do with them... from the "end user" side.
Still, I have to find the plastic bubble wrapping, no one seems to sell that crap in small quantities (they sell rolls of 50-100m, lol). And I need a "perfect" packaging as WD says, even if I am to take the drives to the RMA "office" personally <_< (they then send the new ones with inside the same package as I been told... lazy rats, bothering the end user to find that shit, it's stuff that only companies or resellers seem to buy).

Speaking of hard drives, read/write errors, is it something to be worried about?

My Samsung HD204UI drives have 2 or 3 of those (appeared some time and never again). One drive with 2-3 read errors, and the other with 2-3 write ones :p. No idea what they mean precisely. The drive failed to read/write once but then tried again and it was successful? As I never got any corrupted data, it seems to me that's a "failed once, passed on the 2nd try" kind of error. Ofc, having a lot regularly should mean something bad... even if it then tries and succeeds, so no corrupted data shows up, it'll slow the drive and I wouldn't trust it at all...

As is mine. The drives dock sits on an old TV table, that I made even putting a magazine under one of it's stands (or "feet"), as it was quite unstable. Now it's rock solid :3

Interesting. Aside the drive I mentioned above, I had a WD Green (EADS) 1.5TB that would pop up "pending" sectors when used regularly. It happened once, I did it a full format and the disappeared. But with the daily use, the same happened again, this time though, some "reallocated sectors" showed up too. I heard somewhere about the "magic" of HDD Regen and I gave it a try. Poof, the drive became perfect again. Not even a scratch. So back to normal.
Now, the other day I checked and it has 8 "offline uncorrectable", 3 reallocated and some pending. So I decided to take it to RMA together with the other drive (fucking WD stupid drives >:(). At least I have a few months of the 3 year warranty.
I wiped both drives with the DoD method (the 7 pass one, don't wanna let my... "shady" stuff brought to light :P). The 500gb Blue bad sectors (both pending, reallocated and offline) sky rocketed, but the Green one... as with HDD Regen it was back all to 0, except for the 8 offline sectors :-\
Weird...
