Can't get 1 TB (2.5 " drive) to fit into HP Pro Book 6555b laptop.

[Somewhat_Knowledgeab]

I have my Win 7 system cloned ( 1 TB cloned drive to replace the 160 GB one ). It fits into the HDD caddy but won’t allow it to connect up . The 160 GB appears way thinner (about half the thickness of the new 1 TB one) . Is there a thinner I TB drive (SSD?) that will fit and allow the drive to fit?

What is the make and model of the New HDD and the old HDD?

See if this helps

make sure the drive is 7mm thick, which used to be the thinnest I could get.
I think the default is 9mm.

These are the numbers on the HDD.

ST91000640NS = Seagate I TB ( about 1/2 Inch - 12.7 mm )

HTS725016A9A364 = Hitachi 160 GB ( about 1/4 Inch - 6.35 mm )

I think the replacement drive is too thick according to my measurements

Seagate I TB ( about 1/2 Inch - 12.7 mm )

Hitachi 160 GB ( about 1/4 Inch - 6.35 mm )

Is a 2.5" drive different ( I purchased my two 1TB drives from Amazon ) from a laptop drive or did they started making the specs larger from when the drives were originally made?

[Rustys]

Systems are getting smaller and more compact, and hardware is sometime behind.

2.5-inch drives use to be the standard for laptops.

Have you looked at HP to see if they have drives that fit?

Did a quick search for thin 2.5 drive ssd and found a few yet not sure on the dimensions.

Have you tried looking at some of the local computer shops?

the large capacity drives had multiple internal platters when they first came out.
now they do one platter, hence thinner units.

you need to get a 7mm thick drive as that is the size of your current 160GB unit.

personally, I’d be getting a SSD drive as they have always been 7mm thick - but check first!

Would this work as a HDD - https://www.newegg.com/1tb-wd10spsx-...1Z4-0002-017H9

Further down the page it lists the specs as: Dimension - 3.94" x 2.75" x 0.28" of which the 0.28" converts to 7.112 mm

which is the recommended thickness of the replacement drive that you stated.

Why not get an SSD would be faster and less chances of failure since there are no moving parts.

None of the drives you have asked about are SSDs

I looked at some SSD’s, but they were listed as SATA III.

(I wasn’t entirly sure they would work - the online .PDF manual for my laptop HP probook 6555b only listed the HDD as"sata" not “sata III”)

Unless they are backward compatible I don’t know if they would work or not.

Here is one of the SSD’s I looked at for it - https://www.newegg.com/gigastone-960...0D9-00A3-00005

[Rustys]

Here yours should be a SATA 2

Might also take the original drive with you so they can see a Comparision.
