wondering how long the hdd will last with the usually stiff suspension in most skylines.

Most hard drives are pretty tough now a days. I've dropped a few and they still running fine. If you mount the hard drive sideways as opposed to flat, you'll lengthen the life of the hard drive too.

Yeah they are fairly tough, but I dont expect mine to last much more than a year though... HDD's definitely dont like to be moving when they're spinning! The price of laptop hard drives is cheap now anyway.. You can get a 60GB for $110!

The only way to counter this is with a flash hard drive, but they cost an arm, a leg, and your 1st born child's soul unfortunately.

Like, try $117,887 (yes, ONE HUNDRED AND ELEVEN THOUSAND!) for a Memtech 98GB Flash SATA Hard Drive! ;) Pretty silly when you remember that 4GB USB memory sticks are only $160 now! :(

Yeah, thinking of getting just a 1gig usb2 stick to run windows from. Probably be lighting fast to boot up and shut down on. Probably the only down side of a car PC is that, taking time to boot up.

That shouldnt be an issue!

Go to Mp3car.com and search "tweaks".. Find guides to disable services and crap the pc doesnt need etc... This will shave a lot of time off your boot up from cold.

I havent optimised mine yet, and its running at about 20 sec's boot resuming from Hibernate! By the time I get into the car, and wait for the LCD screen to slide out and up, the thing is pretty much booted! I think I have to look at a black screen for only 2-3 seconds! Youre using Hibernate and not shutting it down every time are you?

The Opus Power supply takes care of the hibernating and shutting down. I think its like when ignition is turned off - goto hibernate - then 15mins after shutdown. Alls I'm saying is that if windows boots quick (20 secs) from a standard hard drive. imagine how fast it'd run from flash memory.

Got some pics of your install Prim?

Ahh ok.. yeah booting from flash would be very quick!

I havent got pics at the moment.. I'll post some up tonight if I get a chance. The only thing you can see is the lilliput 7" motorised touchscreen in the dash. It's difficult to even see the laptop as it's mounted under the drivers seat on a docking station so i can remove it easily.

Which front end are you running?

Yeah thats what you would expect... The read rate and transfer rate are two different things. The transfer rate of USB2 is up to 480MBit/s... Where an average HDD is only about 120Mbit/s...

The READ rate (how quickly the drive can pick up data off the platter) on a HDD is usually between 30 and 70mbit/s...

So the read rate on the USB flash could be faster or slower... Im not too sure. But the Bus/transfer rate on USB2 flash disks is certainly higher. Whether or not thats the actual rate that data is read off the flash chips is another kettle of fish!

^^ This isnt gospel... it's just what I understand from the small amount of research i've done! :unsure:

I guess the best way to test it would be to copy a 100MB file from a USB2 > HDD, and then do the same file from a HDD > HDD. If the HDD>HDD test is faster, then you've got your answer!

There is a huge amount of issues regarding booting from USB2 disks though

    • I have been looking at some setting on the alarms for the Q60 and what buttons do and so and also been looking for details on the alarm in my V37 which is a standard issue with the car. settings like window roll up and a few others seem to not work at all. i cant seem to find exact info on V37 alarms so Q60 is all i can really go off i have not tried 400Z alarm settings or info yet so that will be next. any one got like a sheet of info on the alarm system in the V37 as all my documents are in japanese but i thought the system would basically be like standard through similar models? 
    • I had a fuel smell coming from the drivers rear and pulled the tank out to inspect where it was coming from, turns out the breather hose from the tank to the filler neck was perished. I’m going to Japan next week and I’ll grab it while I’m there  pulled the oil tank apart and started cleaning this crap out of it, some brake cleaner and rags got it looking new again 
    • Hmm. Was quite a few years ago now. I think I bought from a crowd in the US called CDT Audio. The speaker is the HD-6. The HD-6CF would have been the better option (based on T-S parameters), but they were discontinued in 4 ohm at that point in time. The HD-6 is a better driver in almost every other way (than the CF) - just not as good in IB. They still do the HD-6. They might even have a more suitable (for IB) option here.https://www.cdtaudio.com/cdtnew22/products/components/woofers/midwoofers/midwoofers.htm But, here's the rub. I was working in the US a lot back then, so I got them delivered to my US office and then just brought them back to OZ myself. I don't know if they will ship to OZ, and it probably wouldn't be great cost-wise anyway. As to results. They're driven direct off the rear channels of my headunit, because the headunit can be setup to run the rears as subs. So, not a lot of power being fed there. Nevertheless, there's no shortage of volume - the sub levels don't need or want to be boosted at all. The bass is definitely not what you would call "tight". It is definitely a bit delayed compared to a proper sub. But, with the great front soundstage and really good 6.5" woofers in the front doors, I'm getting most of the bass detail from the front and the rear is really only to extend the bottom end a bit. Works for what I'm doing. I mean - until recently you couldn't really hold a conversation in my car due to the fuel pump, and for many years I had tyres so noisy (Kumho KU36 at <50 tread depth) that I had to drive with earplugs anyway!
    • curious to know what drivers you chose and the results? quik mafs, says two 6.5s should roughly equate somewhere between a single 8" or 10" driver. i agree that IB is definitely the way to go in most cars imo.
    • S13 and R32 rear suspension geometry is horrible once you lower it (which everyone does). The camber & toe out ramp is very aggressive, hence it's common for the S13 boys/girls to use a S14 or S15 subframe as the geometry is light years ahead. I'm sure the same can be done on R32s, but I don't know anyone that has done that.
