    Hi All,

    I want to put in a bigger drive into the Acer laptop so I checked the egg and they have WD 250G for 48 including shipping. Just to be on the safe side I emailed WD tech support and asked if the WD2500BEVT (SATA 3G) would drop back to SATA 1.5G for the laptop.

    This is what came back and I am inclined to not believe it as I got the two model numbers he quotes in the first line from the Newegg site and the first is SATA II and the second SATA I...

    Thank you for contacting Western Digital Customer Service and Support. My name is Tahimi

    I apologize for the inconvenience, unfortunately the WD2500BEVT or the WD2500BEVSRTL are not able to perform 1.5 Gb speed. You will need to look for a SATA 1 hard drive like the WD2500BEAS.

    I hope that we have met your expectations today and that you are satisfied with our service. If you have any further questions, please reply to this email and we will be happy to assist you further.

    Sincerely,
    Tahimi

    Anyone care to comment on this? I always believed that a SATA II drive would also handle SATA I.

    Thanks

    Dave

    Generally they drop down, not sure why those would not. I have used WDC SATA 3G drives in older desktops and laptops without issue. The only issues I've ever had were with VIA SATA controllers, never had a SATA 3G drive work on a VIA controller without being limited to 1.5G mode. These drives do not seem to have the jumper to limit their mode from taking a quick look the the WD site, so maybe they can't drop down.

    What laptop is it?

    Its a gamble on your part, WD has informed you it does not support 1.5.

    Most of their desktop drives have a jumper that needs to be set to use it in 1.5 mode, unfortunately their laptop drives do Not have this feature.

    Thanks Triple and Mumbo, I will take them at their word I guess. Although it would only be a minor gamble as I am sure I can use another 250G drive here somewhere. :)

    However if the desktop ones require a jumper and 2.5" don't have them, I will go with the 1.5G for the Acer Aspire. Bummer as it is almost 20 bucks more with shipping.
