HP6820s and 7200rpm HDD

Hi everybody

 

Can a 7200 rpm HDD be installed on a HP6820s laptop?

Had anybody tried this operation?

 

Thank you.

Re: HP6820s and 7200rpm HDD

Hi:

 

According to the quickspecs on your notebook they only list 5400RPM drives.  See the section on storage.

 

http://h18000.www1.hp.com/products/quickspecs/12768_div/12768_div.HTML

 

The parts list in your service manual only lists 5400 RPM drives. See Chapter 3, page 17.

 

http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c02014623/c02014623.pdf

 

On the nc6400 for example, there are both 5400 and 7200 RPM HDD's available.

 

That would lead me to believe that 7200 RPM HDD's are not supported in a 6820s.

 

I don't know enough personally about what would happen if you installed a 7200 RPM HDD in your notebook. Would it just run at 5400 RPM, 7200 RPM or not work at all?

Hi Paul

 

I think it is not like in the memory case, that if you mount 667 memories and they run if required at 533. A HDD can spin only at 5400 if manufactured for 5400, or 7200 if so.

I'm thinking that the manual specifies, I hope, the only possible configurations HP delivers the 6820 laptop, not the supported HDD specifications. For the capacity there might be a problem but I don't see what could be the problem if it is at 5400 or at 7200 if the interface is still SATA.

But I don't want to buy one and than to see that it is not working and I don't have anybody to buy it from me and I don't have a store where we can give it a try. The second chance, if it is not working ,would be to buy an enclosure and use it as an external storage, but in this case I better buy directly an external HDD.

Re: HP6820s and 7200rpm HDD

Hi, Calin:

 

What you write makes sense. I guess it is up to you if you want to take the chance. It might work. I can share a couple personal examples...I still have an old Dell C610 notebook. It came with a 4200 RPM IDE HDD. The HDD failed, and I didn't even think of what would happen if I didn't buy another 4200 RPM drive. I just went and bought a 60 GB 5400 RPM IDE notebook drive and it worked just fine and the computer's response seemed faster due to the higher RPM.

 

Also, I have put in 7200 RPM drives in old desktops that had 5400 RPM drives, and never experienced a problem.

I'm back

 

I tried a 320 GB  / 7200 rpm / 16 MB buffer WD Black Edition and it works.

I just finished last night installing it, so there is no 250 GB / 5400 rpm limitation on this notebook

 

Thanks for support
