Hard drive enclosure to turn internal into external? Answered

Hello all,

I have what may be a dumb question - so hopefully it will be an easy one to answer!

I have a couple old hard drives from old computers that I want to put into a case/enclosure to repurpose into an extra external hard drive.

When I take exact measurements of the hard drives they are: 4" x 5 3/4' x 1 (W x L x D).

I've been looking around for enclosure kits but I don't see any that are 4" in width. I see a lot of 3.5" and not many others besides smaller 2.5" casings.

So my possibly stupid question is: Do I want the 3.5" enclosure for my hard drive? I know that sometimes the sizings can be off when it comes to stuff like this.

Thanks for the help,

3.5 inch drives are considered hard drives from desktop models of PCs. They fit in industry standard sized mounting slots. 2.5 inch drives are the smaller drives you find in laptops. You may see 5 1/4 inch wide slots or bays on PCs which accommodate cd/dvd drives, hard drives with mounting bezels, floppy drive wide mounting...but external drive cases are purchased according to the size of the drive. Good luck.

. 3.5" is the size of the platter, not the HDD unit itself. A 3.5" HDD is about 4.125" wide.

Can you post the model numbers of the drives? We can then find out what drives they are and then tell you what ( if anything ) can be done with them.
