USB Disk vs. USB Stick

Hi Experts,

Can someone explain me the difference between an USB memory stick and an external USB Hard disk. Yes I can see the difference (in model and size) :-)

But some hardware can read memory, but refuse to read an USB disk. e.g. my hard-disk recorder, my car stereo. How can these kind of hardware recognize the difference and can I do something to let the HD act as a memory stick?

Thanks,
Murphey

Well there are different classes of USB as well as different power consumptions.  Different drivers / loaders will used depending on the device.

As Fox85 said, there are different file systems.  Windows can't read Linux or Mac file systems you might find on a hard drive without a special driver software.  But most USB Memory Sticks are formatted with FAT32 Windows/DOS format to give them a format that almost all systems can read.  If you reformat a memory stick to a Linux or Mac format, Windows won't be able to read it.

Thanks :-)

The USB Hard disk has his own external power.

Yes I understand the part of the Filesystem, but we are not talking about Windows of Linux Systems, but about a Philips HD-Recorder and a Car audio system.
The last one is the most important:
It recognize the disk because the display shows (No media files found on USB Device),
So I can try to change the format from NTFS to FAT32.

(I also tried to find-out what the max supported Size is for the Car audio, but it seems that nobody knows)

Thanks (let you know the result),

What model is the Car audio system device?  Some devices like that do use a Linux file system.  You should be able to look at "Properties" and see what file system Windows thinks is there.

I found two pages that said that the Phillips HD Recorders use FAT32 formatting.

Fat32 format for a 120Gb HD is not possible so that option is not solving my problem,
How do they do that with a 128 GB Memorystick ?

I will try to get one to test if that is compattibel with my car's audio.

FAT32 will support larger sizes than Windows OS will allow for it, up to 2047GB.  Swissknife http://download.cnet.com/CompuApps-SwissKnife-V3/3000-2248_4-10070864.html will format the larger disks for you.  Here also: http://www.compuapps.com/index.php?option=com_content&view=article&id=126&Itemid=190  It is also what someone used to replace the harddisk in their Phillips unit: http://forum.videohelp.com/threads/311434-I-fixed-my-Philips-DVDR-3455H-dvd-hdd-recorder

There are some other programs that will do it also.
