#1: Electrical Question :) Author: LeeMaddern, Location: ScunthorpePosted: Sun Aug 21, 2011 4:46 am ---- Okay, so as most people do, i have to many albums, to fit onto ipod, phone, cd's, or memory sticks. so i was wondering -
can you convert a normal external Hard Disk Drive, so run of 12v the car puts out ? ( correct me if it isn't 12v, because i dont really have a clue ).
i was planning on putting the HDD into the glove box, and running the USB cable to the back of the headunit ( where the usb slot it ) and then the power cable of cars power circuit.
the HDD is wireless, so i can set it up, so when my cars turn on ( HDD is on ) my laptop will automaticaly move all recent downloaded albums onto the HDD in my car, sort of like automatic back up.
this will then save me time, putting albums onto different memory sticks or loads of cds or different ipods.

you need at least SSD.

SSD is specially design for mobile application, as it contain no moving parts compare to the normal HDD (disc+reading pin)
when normal HDD is reading/ writing data into the disc, if you hit a a speed bump or pothole then the disc will be damage.

Worked out the other day that I have 1200 hours of music on the HDD and still more to go on.

Should be able to get plenty of music on that
#9: Re: Electrical Question :) Author: qwert, Location: ukPosted: Sun Aug 21, 2011 7:12 am ---- Headunits generally only run FAT32 which is a 4gb max, they wont normally run NFTS
#10: Re: Electrical Question :) Author: jimjam19927, Location: PortsmouthPosted: Sun Aug 21, 2011 7:38 am ---- As above most head units only take-up to 4gig max
#11: Re: Electrical Question :) Author: MrBSI, Location: What's it to you? ? ?Posted: Sun Aug 21, 2011 7:48 am ---- Looking at the owners manual for this head unit it says:
A USB memory device can hold up to 10,000 files/1,000 folders
This device supports FAT 12/16/32.
A single FAT 32 file has a maximum limit of just under 4 gig.
If the files are sized / structured correctly then a large USB stick will be fine.

WD makes both 2.5" and 3.5" USB drives - 3.5"-ers run off 12V and come with an external power supply (brick/wall wart).
Some 2.5" drives want more power than a typical single USB port can provide and then come with a special cable with 2 male A type connectors at one end, one of which only has the power and ground wires to suck power from a 2nd USB port.
But generally 2.5" drives (not only WDs) can be run off a USB port w/o extra power.
As to the survivability of hard drives in a car depends on on how they're mounted and used. For instance the empeg (aka Rio Car) player had its drive(s) (1 or 2 2.5" drives) mounted on a plate in turn mounted on rubber buffers in the player chassis and only spun up the drives as needed to read and fill the RAM buffer...
Haven't had a drive go bad in the 10 years I've been using my empegs (oldest drive about 6 years in operation (drives have been replaced as available size has increased, but replaced drives have lived on as sneakernet units in external USB chassis. and that's in a stiffly set lowered Polo and stock suspension 180/RC.
