External SATA hard drives using USB ports not recognized by Windows XP on Dell Latitude C840 laptop
Posted on 2008-06-14
I have long used IDE pocket-sized external hard drives with my Dell Latitude C840 notebook. However, I've now tried Western Digital and other SATA pocket external hard drives on the laptop and they NEVER show up at all on Disk Management of Windows XP Home OR Professional. NOTE: These same hard drives ARE recognized by my Sony VAIO.
The Dell Latitude C840 has USB 1.1 ports (the external hard drives connect to these). I have tried both these USB 1.1 ports directly as well as hooking them to a PCMCIA card that upgrade the laptop to USB 2.0. The various IDE external hard drives work fine... the SATA
The Laptop Bios is upgraded to the latest version. Basically, I've tried every possible combination to rule out everything (USB port problems, Windows XP problems, etc.) except that there might be an inherent problem with using a SATA external hard drive on this laptop. If there's a workaround that I don't know about, I'm willing to try it. If SATA external hard drives simply don't register on some laptops/computers, I'd appreciate knowing why.
