    Angry HD Died! Replaced With Laptop Drive...

    About a month ago, my 10.2Gig Quantum desktop drive begain to fail. At first, the player would just freeze up. Then, the drive began making a clacking sound as it continuously reset (head parking/unparking over and over). Early last week it began hard to boot up, sometimes requiring up to 10 tries. Then, Thursday afternoon, it died.

    I was able to get a laptop drive and IDE adapter by Thursday night, and was able to persuade the drive to boot up one more time to Ghost over to the new 6.4Gig laptop drive. It is a smaller drive, but I can't see even getting it to 3 gigs anytime soon, so I'm not worried. The transfer went fine, and I am glad to report that after some serious punishment Friday night (drag racing, a little bit o' rallying, etc) everthing seems fine.

    I have always been one to do things right the first time. I orginally planned a laptop drive, but since others have had good success with desktop units I opted for the cheaper solution. Now, instead of buying 1 drive, I have had to buy two. I guess that just reinforces teh point that it is best to get it right the first time, as it will be less hassle in the long run.

    Well I know that Maxtor bought Quantum (merged or whatnot) but do you remember the specs that came with the Quantum HD? Mainly referrring to the shock numbers...

    My western digital's been holding up for... *thinks about it*

    Wow, almost 10 months now.

    How long did you have yours before it died, Aaron?

    yeah, from what ive witnessed, Western Digital hard drives fail far less than Maxtor drives. But, thats just what ive seen from personal experience.

    It can be hard to find shock specs (most HD manufacturers don't make them easily available for desktop/server drives), but usually desktop drives are rated for 20-40G/2ms shocks.

    Laptop drives are rated much higher. For example the IBM laptop drive in my player is rated for 180G/2ms operating and 800G/1ms non-operating.

    Cool

    Personally, i think the reason the drives are dying on you guys is quite simple. Seems that u guys fasten the drive or mount it to the body of your case. I know Aaron at one point said he had like a shock absorber thing but still it is fasten to the case. Now take into account when u get into a pot hole or bump, you are basically swinging or bangin that harddrive. I might not be explaining it correctly, but this is how i killed my prototype HD when i started out with my setup. I have a 13gig HD that is still in my first box and still works fine and this is over 1yr ago. My second box uses the same type suspension as in the first one, but slightly modified. And so is my first customer box. If you guys really want to learn how to mount your HD correctly, take a look at this pic on my site.

    On the other hand, i had a 6gig toshiba hd that was in my second prototype box for the second box, that is now DEAD, thats right DEAD. I couldn't figure out y since these suckers where made for extreme laptop.....well u know the rest.

    This is still a heavely debated topic! So far censwesi and aaron are pretty much the onely ones ive ever heard of drives failing out (other then reasons of over heating) Granted it proubly would be better to have a labtop drive but thats way too expensive for size i currently have in my system. Im going on haveing the system mounted in my car for almost a year with no problems what so ever... the first version had a absorber but now it is just mounted in the case for a while. Basically for the number of hard drives we all have and the number you hear that fail from the people that claim they hit a pot hole or something can easily be chalked up to just bad hard drives to start with. Ive had it happen before to my desktop unit that after 10 months i found out the drive was crap. Basically if there is something wrong with the drive dont assume its cause it was in your car.

    Talking

    The HD lasted for 1.5 year of hard driving. That is, speeding, hard stops, 7(!) accidents (not my fault), drag racing, etc.

    Yes, my HD is hard mounted to my case, but there are rubber bushings and the whole case is mounted on 4 shock absorbers.

    Quantum incorporates several shock protection schemes designed to work while the drive is running. Their site has all the propaganda about it...

    One word.....SEAGATE.

    These babies last! I had an 8gb one to start with, this is still working perfectly, but I upgraded to a 30GB and it is fine also. I have them mounted via 4 rubber gromets, but that's it. Gravel, rallies (wrx's are good for this you know pot holes, you name it, these drives deliver. (sounds like an ad doesn't it !) But I have never heard of a Seagate dying yet. They are cheap and damn good. I have made 4 players so far, and they are all still working sweet!

    Forget Laptop (tiny) drives, get a good sized 31/2" baby in there...Segate of course... and you can't go wrong.

    Well that's 5 drives that I have had personal experiences with that have lasted in a car environment. Before these, I had a Western Digital, and 2 Quantums....

    All are deceased ..*sniff*

    Quantum's main two shock protection methods (in SPSII) is

    a) stiffer head arms, so that the head can't bounce as much
    b) delays writing till after shock, so as not to scatter data

    (b) isn't a big factor for us, as we're mostly just reading.. (a) is being done by most hard drive manufacturers, despite them not having fancy names for their shock protection systems. They do care about shock protection though, as poor shock protection means high replacement rates.

    Quantum doesn't disclose operating shock ratings for it's drives, only non-operating. You'd think they want to brag if it was so good. They list non-operating shock ratings 'as high as' 300G/2ms.

    Compare this to Maxtor who doesn't boast any whitepapers or special antishock technologies, but are willing to share their shock specs. Pretty much all their drives are rated for 25G/2ms operating 250G/2ms non-operating.

    Then compare that to a laptop drive like IBM's. 175G/2ms operating and 800G/1ms non-operating. I'm not an expert on accleration, but it seems that 250Gs over 2ms should be roughly equivalent to 125Gs over 1ms (half the time period). In this case, a typical laptop drive handles 6x the non-operating shock ratings and 6x-7x the operating shock ratings.

    Anyway.. normal drives do seem to be working for most people, but I'd rather play it safe than have to replace things later.

    But I am skeptical of Quantum's ballyhoo'd Shock Protection System II (SPSII), as it appears to be nothing more than what all the other drive manufactuers are doing -- drive manufacturers who openly share their shock statistics.

    Oh yeah, for those looking for the SPSII whitepapers, you'll find them on Maxtor's website, as Maxtor aquired Quantum's hard drive division.
