I have an HP dv6837cl laptop. The original hard drive is a Samsung HM250JI which crashed and needs to be replaced. This hard drive is now more difficult to find and I've seen instances of others on the web who have also encountered issues with this HD so I'm even more concerned about trying to replace with an original part. The original hard drive is labeled to replace with HP spare 453775-001. It appears that this is no longer available from HP which instead pointed me to a 613051-001. The 613051-001 (based upon the HP site) does not appear to be compatible with my laptop. How can I determine what other hard drives are compatible replacements for the original?
