What is the difference in WD5000BPVT hard drives with model ending with -22HXZT1 and -00HXZT1?

Hi, I have a near three year old notebook harddrive titled “WD5000BPVT-22HXZT1” that recently failed. I suspect that the warranty has expired.

I’ve found a potential replacement on Amazon, but the model number is a bit different: “WD5000BPVT-00HXZT1”.

Are they compatible?  May I replace one with another?  I have an Acer Aspire 5750.  What does the last sequence mean?

Thank-you.

Hi it makes no difference any BPVT drive will work fine. So the WD5000BPVT-00HXZT1 will work ok, the other number’s may mean firmware changes it is a WD code so really only they know.

The model number suffix is a Customer Configuration Code. The first two characters are the Merchant ID.

00 = Generic (retail version)
22 = Acer ???
