'Seagate Momentus 5400.6 500GB 2.5" SATA Laptop HDD'.

Hello,
Greetings I am looking for a replacement Seagate Momentus for my HP Laptop possibly like the hard drive above you have for sale. I currently have a 5400.2 120GB and want to upgrade it to a 500GB. The serial number of my current unit is SN:5PL2F5YD Model: ST9120821AS PN:9W3184-022 and FW: 7.24 Please forgive me as I live in Samoa and also live in Nelson but am driving "blind" on this errand. Will your unit be the correct replacement for my faulty 120GB Drive? Many thanks

Hi there, thanks for your question. The model you have described is a SATA drive, which is the same as this model. Based on that, I would expect it to be compatible, but it may be worth contacting HP to confirm this. Another option could be to ask for multiple opinions by posting on a PC hardware forum such as this one: http://www.tomshardware.com/forum/forum-32-204.html . Hope this helps :-)
