I am a computer re-seller. I've installed over a thousand hard drives into laptops but have not had this issue.
I just bought 10 Dell latitude D620 and D630 laptops (2.5 in Sata hard drive).
I just installed ten of these bought via Newegg Refurbished:
Seagate Momentus Thin ST250LT007 250GB 7200 RPM 16MB Cache SATA 3.0Gb/s 2.5" Internal Notebook Hard Drive
The bios does not detect them. Can you guys make any suggestions as I don't see a way to manually change the bios to detect this thin drives. I am using the regular dell d620 and d630 hard drive caddy's. They all work with the regular (non thin) hard drives but they were too small (only 40 gig) .I have re-seated of course. NO luck. Please feel free to make any suggestions.
I have solved this problem. I had to very carefully re-seat the hard drives by guiding them with a little extra care into the sata interface. Since they are thin they were not quite lining up.
Thanks guys... Leaving this up in case it helps someone else.
