Whats the difference between Western Digital Caviar Red, Western Digital AV-GP, WD Enterprise RE4, and WD Caviar Greed?

So many labeling im also confused.

All I know that Red is for work stations and CCTV and hence durability.
well green is to safe energy but migh might not be durable
Not sure bout AV-GP might be similar to red but do not know if there is much diff

totally clueless about Enterprise RE4.
*
Red is for NAS and/or RAID.
AV-GP is for CCTV.
Green is for normal but reduced energy usage.
RE4 is for enterprise usage.

besi buruk dont offer good turn in price  cry.gif  cry.gif

i heard some IT vendors collect and sell it part by part.. if besi buruk rm10 but the IT vendors they say can get up to RM200 =( depends on your hdd type .. hdd sounds like a gold  smile.gif
*
RM200 sounds ridiculous, at least for common HDDs that can be had for less than that. Maybe they're also stealing the data from the HDD? It is possible to extract data from dead HDDs. So dead HDDs that once belonged to a finance department, celebrities or other people of significance could be valuable.

How old is your HDD before it died? The F1 is a pretty old model.

my warranty has expired... but i really need my HDD to be repaired.. anyone know where i can go to replace the PBC board?

If you need the data on the HDD, please do not send it back to the manufacturer for RMA. The manufacturer will almost certainly give back another HDD, with a different serial number and without your data on it.

Hi new here, is there any brand of 2TB 3.5 HDD recommended more than others? I'm just looking for storage and reliability, performance speed is is not a main factor.

Unfortunately I haven't heard of a recent RMA statistics of that kind, so there's no way I could objectively state which modern HDDs are in the list of top 10 HDDs for reliability and durability. There was such a data reveal, but it is two years old now and is probably no longer true today.

You can always choose to go with popular opinion.

yeah im also wondering which is the most relaiable hdd around in the market i got the Westernd D 3TB Red for photo/audio/video (memorable storage) but still do not know among

Western Red
AV-GP
RE4

which is the toughest durable hdd. AV-GP and Red have similar shock withstanding standards....

What about other brands? All I know is that Western D is kinda catering for a more durable market since its for long running devices like 24/7 CCTV and 24/7 Servers. hmm.gif

So confusing thesedays

In that case, it would sound as a bad idea to give them as I do keep a lot of financial analysis on my hard drives and yes personal financial details. If the hard drive is dead any way to complete wipe it although it partially detects the drive? hmm.gif

The only way you can guarantee that your data is not casually retrievable without authorisation is to use full disk encryption (FDE) and a good password. But you'll have to do this before the HDD died.

Truecrypt is a rather popular third-party FDE tool, or on Windows you can use Microsoft's Bitlocker. Don't do partition or file encryption, as copies of your data can be leaked to unencrypted portions of your disk; do full disk encryption. Be warned however, if you lost or forget your password, the probability of cracking it is very low unless your password is weak. There was an unfortunate fellow forumer who had forgotten his password and all his data was effectively lost.

If the HDD is already dead, then the only secure way to destroy the data is to dismantle the HDD and damage the platters. Of course, this will void any existing warranty.

Do note that the HDD's PCB has some value in the HDD repair market. Sometimes the HDD failure is due to damage on the PCB and replacing the damaged PCB might restore the HDD back to working order. They'll need some rather detailed information however, as PCB incompatibility is also rather high.

I guess you can hammer your hdd plates after you have dismantle them as they were being stored magneticly and put it under a magnetic field

In the HDD, there's a pair of magnets that are strong enough that you really don't want your fingers to be between them when they snap together.

I don't understand why magnets is a popular thing to use to erase HDDs when the HDDs already have the strongest magnets that I have encountered located next to the platters themselves. rclxub.gif

Edit: Oh, that explains it. Somewhat. http://www.dansdata.com/magnets.htm#drivemags

Edit 2: And this one appears to debunk the magnet myth, at least in 2006. http://cobolhacker.com/2006/10/28/is-it-po...e-with-magnets/

Do you know any shop that does the PCB repair? Do they still do the old hdd like maxtor that uses IDE slot? I have one harddrive i suspect is the PCB dead but i dont seem to be able to find anyone to fix it. The problem is the hdd is detected but the name is like symbol alphanumeric and some other stuffs.. The hdd does not show in the OS or system manager.

Truecrpyt of the legends and one of the most headache software if you forgot the password. I seem my friends having the same issues.

Unfortunately I don't.

And it seems that it is possible to kill a HDD with magnets, but you'll need a really strong one. http://www.technologyreview.com/news/40595...l-a-hard-drive/

The magnet sit not between the disc.. and they not effecting the disc data...the magnet does impress me bcoz they are relativity small but powerful interm of stick to metal but not that much to snap finger..

as wat i know there two type of magnet that either gonna effect or not.. for speaker mostly satellite speaker will have magnetic shield label shown that will not affect HDD or even monitor.. if u still have crt monitor try take magnet put on the glass screen u will see rainbow colour at the screen.. unless the magnet as such subwoofer which normally not magnetic shield then better put not near to PC casing...

what type of solenoid u think maybe in HDD? as far as i remember no solenoid were included in the manufacturing process..

that magnet will come in handy when you need to unscrew some REALLY TINY screws, like the glasses/watch/HDDs.
