Is it possible to connect an external Hard drive to the headunit through usb?

For example: i have an alpine w404. Connected, through usb, is my iphone. Is it possible to, instead, hook up a external hard drive for my music/movies/videos?

something like this Seagate - 250GB External USB 2.0 Portable Hard Drive - ST902504EXA101-RK (http://www.bestbuy.com/site/Seagate+-+250GB+External+USB+2.0+Portable+Hard+Drive/9690449.p?id=1218180729662&skuId=9690449)

Read your HU's manual. It will probably have a limit to the number of songs it can read and/or tell you specifically what kind of media it has to read from.

^This, the box even sometimes will tell you how much power it puts out or what type of Hard drives it can read. More then likely you can buy a nice external/portable HD to match your needs.

No. First of all, your head unit reads only fat file systems. Since fat32 only supports up to 4gb you have wasted your time with a hard drive as a 4gb thumb drive can easily be purchased for ~$20.00.
This makes it impossible of course for your head unit to be able to use a 250gigs of storage since it is limited by fat32 and the large hard drive would need to be partitioned with ntfs to take advantage of anything more than 4gb.

Also, most head units do not allow for video to be played from their usb input. I don't really know why this is, but they just don't yet.

Your HD will need to be formatted in FAT32 (not NTFS). You can only use an external HD that doesn't draw more than 500mA. You can only play those file types.

No, the 4GB is the maximum FILE size, not volume size. It will work fine, depending on what program he uses to partition and format the drive.

Yeah my memory failed me. I wasn't right about that and was corrected above.

I wanted to use a hard drive and mount it.. it would be great but had to settle for a USB flash drive myself.. lol..
Only think i dont like about it is it can only read 1 folder deep.. from the root..

The one i have can read more than one file. but since it cant read video files then i might as well get a ipod..

the 500ma draw wont stop him either if he gets an external that uses a stand-alone power plug. like my uncles fantom 500gb has usb for the data transfer but it derives power from a 12v wall adapter. which means he could get a huge HD and just get a lighter socket power adapter from rad-shack to power it.

True, but I chose to ignore that possibility since most external hard drives that use an external power source are larger in volume, in which case would be pointless due to the FAT32 formatting.
