Does Hard disk enclosure also depends upon size of Hard disk

i recently bought a 2.5 inch enclosure to recover my data from my laptop 500GB Seagate harddisk. But when i plug all the cable the Derive was not visible in "My Computer" window but computer gives a sound which it usually gives when you connect a USB device to it. And then after scratching my head for some time i came to know that , there is written at the back of the box of enclosure (very bad quality box) that "The maximum support capacity 120 GB" . So my question are :

1. does we have to consider the storage capacity of the Hard disk when buying a enclosure for it?
Can it be main root of the problem that i can't see any derive in my computer?

3. It's written on the hard disk that " DC +5V ---0.85A " (i assumes it means it required 0.85A) current to operate. But when i plugged in the enclosure and check out the properties of the respective USB port in Device Managar , then it shows the connected device required 2mA and The total power available 500mA per port. Is it creating any problem for me?

Thank you.

Please elaborate on "recover my data".

If the hard drive died, plugging it into another enclosure will not magically bring it back to life.

Your questions: 1 - that is most likely just a disclaimer that is on most enclosures and is related to the largest drives that exist at the time. Basically it is to cover the maker so if there is a change in the future that say the SATA protocols change - that someone can't sue them because the 20 year old enclosure they have doesn't work on a 2PB drive.

3 - What type of drive is it? A 10K rpm drive or something with very high power draw can exceed the power available on a single USB port. Often enclosures like this have a special usb cable that connects to two usb ports (for 2x power) but only connects the data signal cables to one port. Alternatively try using a powered USB hub as some will supply >500mA.
 
A usb port does not normally have sufficient power to both power a hard drive and also handle the I/O.
There are some adapters that have 2 usb connections that can do the job.
Or, look for an external enclosure that has a separate power brick to power on the drive.

First of all thanx for reply,

Actually my hard derive is not died up , i formatted the whole derive while installing ubuntu in it now i am trying to plug it into my friend's laptop using some kind of enclosure/SATA to USB adaptor and use some kind of recovery software on it.

1. So does that mean i have to replace my case which can support 500GB derive?

3. It's a 500GB Samsung M8 5400 RPM HDD , 2.5 inch. Yes i got a Y connection usb cable that have 1 thick cable port which support data + power and other thin cable port with only power supply. Will power USB hub with a separate power adaptor will work in my case at any cost(mean i don't have to worry whether it will work or not).
