Are Toshiba drives made for HP compatible with Toshiba drives made for Lenovo if the part number is the same?

I have a HP Elitebook 2730p with a failing hard drive with an HP part number of 516486-001 and a general model number of MK2529GSG.  I'd like to replace it with an exact match, however, these old drives are bit hard to come by or are jacked up to $300+.  When searching around for this drive I do see some that match the model number of MK2529GSG, however, the label is a bit different and has Lenovo on it.

Should these two be interchangeable or is there some sort of proprietary bios/firmware concern I need to worry about?

I see a few of the Lenovo branded drives for about $100, much more reasonable.

Inexpensive and reliable vendor suggestions also welcome for this particular drive.

HP's website saus the hard drive is "80/120 GB 5400 rpm 1.8-inch SATA hard drive".  This is a small and somewhat rare, part but no, you don't need to get an exact model replacement or anything particularly branded.  Any 1.8 inch SATA will do the trick.

Sorry, I didn't notice you said exact match and my link to newegg was a 250GB model.  Not sure where you can get the original capacity any more.

i have not seen any "some sort of proprietary bios/firmware" for  drives in commercial laptops
so you won't need to worry - as said, any 1.8" drive will do
what is the reason for wanting an EXACT match ?
