I wish to replace my old laptop hdd(WD2500BEVS-250 GB) at SATA 1.5 Gb/s with a new one(HTS721010A9E630-1TB) at SATA 6Gb/s.Will this downgradation from 6 to 1.5 work on the laptop with:
CPU:Intel Core 2 Duo P8700@2.53 GHz
Ram:4GB
Motherboard:Lenovo 2743A92
HDD:WD2500BEVS (250 GB)
Also both the drives have identical dimensions.
Please Help Thank You
Any Sata drive should work. Your Sata bus is probably 3Gb/sec and data transfer will work at that speed.
Hey there sportsfanatic,
SATA 1, 2 and 3 are backwards compatible and the HGST drive should work just fine in there at reduced speed (most probably SATA 3 Gb/s).
As for the old drive, I could advise you to run the WD Data Lifeguard Diagnostic tool to make sure it does not have any issues and use it as a backup for you more important information. Here's a link: WD Support / Downloads / Other Products / Data Lifeguard Diagnostic for Windows
Hope this helps,

"On the drive side, your understanding is correct, SATA interface speed is downgrade-able, that means that SATA 6Gb/s drive can work in 3Gb/s or 1.5Gb/s line with ease. However, on the motherboard side, there are older motherboards which do not recognise a SATA 6Gb/s drive at all, the drive needs to be recognised first before it can handshake the interface speed to go to the lower interface speed.
In such scenerio, we would advise customer to find a SATA 6Gb/s system first, then plug the SATA 6Gb/s drive in and run a utility to lower the drive interface speed lower to that of 1.5Gb/s."
My Question:Will i be needing to lower the drive interface speed to 1.5 Gb/s to be able to run it on my laptop?
Check the jumper settings for your WD drive.
Link is not your drive.

Can you please elaborate on the jumper settings as i am a layman to this subject? I can't find the jumper settings for this drive.
