Hard disk replacement - any limits

Compaq / Presario r4000

Specs: Windows Vista, AMD Athlon 64; 1 gb
is there an upper limit to the size of hard disk I can replace my current hard disk with?

I have a Compaq R4000, with Athlon 64 processor 3500+, 2.20 GHz with 80GB HD and 1GB RAM (to be upgraded to 2GB). The hard drive has become too small for my needs and i want to bypass the need to carry an external hard drive. Any ideas will be appreciated. Cheers,

You can install any IDE laptop drive. It used to be larger capacity laptop drives required more current but that no longer applies for newer laptop drives. 160gb and 250gb drives are easy to find, but the major makers are phasing out making IDE drives, so despite there used to being 320gb and 500gb IDE drives as well, those sizes are now getting very hard to find except used.

You can use AcronisTrue Image - the trial version is fully functional for 15 days - to copy the entire contents of your existing internal drive to the new drive, if your exteral drive case is IDE and you can install the larger drive in that, or if you get yourself an IDE external enclosure.

Thanks Tubesandwires. So do i take it that there is no upper limit - that is if I can find, say, a 500GB hard drive of the right form factor (2.5) thelaptop should be able to handle it without any problems.

I recommend that you first check with HP about that. Laptop controllers are more custom than desktops. You may have an arbitary limit. Below is a link to the contact information.

Search the web for: hard drive "presario R4000"
- there won't be any seller's listings for sizes that won't work.

Tigerdirect had listings for laptop (2.5") 500gb IDE ones when I checked a couple of weeks ago but were out of stock - so were every one else on the web with 500gb IDE listings.
