My HDD is dead...right? [UPDATE 3]

It started dying. So you will have to buy a new one.

I would avoid seagate, they are known to have a bad failure rate. the infamous click of death

i have a faulty seagate drive that i have managed to keep working ( faulty as in the device had a recall order but i nvr returned it)
its an old 500gb drive ( so old its sata 1) it has the click of death and it only reads as a 400gb drive now and instead of 6300rpm it runs at 5200 (even when it is on high load) ima stick with it till it totaly dies

hitachi is really super hdd, get it without a doubt
p.s My hdd is have same issue as your, so i connect it like external hdd thru usb thing (forgot how it called), and its ok :P

p.p.s Do not buy toschiba, worst hdd ever

It's a long shot, but try this:
(On Windows 7)
Start button -> Computer -> Right click your HDD -> Properties -> Tools tab -> Check for errors -> Check both checkboxes and start.

I once had a similar problem and doing so fixed the issue. Only, it might take a whole day to complete, depending on your HDD size.

Its basically got a terminal disease at this point. You may have some time with it left, but its on its way out. Download HDSentinel as they may be able to give you a sense of how much time is left.

A few months ago mine had very similar problems with reallocated sectors. I backed up everything I needed to and I kept getting blue screens in Windows 7. Then one day, I got a blue screen, went to restart and it said my OS was gone. I reinstalled Windows and surprisingly that bought me some time, but eventually the blue screens returned and I got sick of the hassle and just bought a new one.

HDDs come with some extra sectors that reserved initially. Once sectors on your HDD starts to throw errors those sectors is marked bad and some of the extra sectors is reallocated to compensate for the "lost" ones.

Depending on your definition of "dead" the disk would be dead. I would replace the disk ASAP even if the disk may run well for a few years. I guess it depends on how important the data on disk is, if it is just a collection of steam games and some movies you might as well keep the disk until it really breaks down.

Make sure you back up the important files too!

I believe that this is a better HDD than the one you posted.

oh im glad they give you a form of warning i thought when a hardrive would die it would just...die

i think everyone sooner or later is going to have an HDD or SSD issue... i had some old HDD that worked for 10 years and a new OCZ SSD that died after 4 months...

Remember to disassemble your HDD for the aluminum and the cool magnets. The scrappy pays good for aluminum.

Just make sure you check the height of a potential HDD. They aren't all the same, some may be taller then the one in your laptop.
Check with your laptop manufacturer which size you need. Oh, and remember to see which manufacturer has the best guarantee/warranty for you.
