HDD size limit for 1,1 Macbook (early 2006)

Hi i have an early 2006 Macbook 1,1, 2Ghz, 1gb sd ram, 13inch monitor. Last year i upgraded the HDD from 80 Gb(original) to 500Gb seagate HDD with snow leopard. it worked well for a year though a bit slow which was attributed to snowleopard and then crashed.
Also i must add very importantly my battery had completely given out, no battery life whatsoever, so a couple times when the power cord would get yanked off , the system would shut down.Now the 500Gb HDD has been reformatted and fixed back with a new battery and it seems to work well. However i havent yet loaded all my data back into it as i have recieved conflicting opinions.
one opinion says that i should use a hard drive with maximum capacity of 250Gb as that is the maximum my particular macbook can support.
Another opinion says that size does not matter as long as it fits into the laptop.Does anyone have a clue about what is correct. do i need to change to a lesser sized Hard disk drive?

To the best of my knowledge there is no HD size limit for a MacBook. The only limitation are the physical dimensions of the HD (some larger drives over 750gig can be too thick/tall)...not the amount of storage (gigs) inside of the HD.

I can confirm that whoever gave you the rubbish that you attribute to "one opinion says" is completely wrong.

I have checked a few sites that all suggest the 500 GB drive us fine as long as it is physically the correct size for the drive. Here are a few:

The idea that it could not take a larger drive might have been because at time larger drives were hard to come by at the correct size. If the new drive used more power than the old one that would shorted the length of time between battery charges.

thank you

yes i have started using my macbook and loading all my data back into it.
Thank you all
