My Passport external drive can be detected by my desktop (window xp) every times, but it will disconnect automatically after using for a while. Do anyone reach the same problem like me? I am wondering if it is due to the unstablization of eletricity or not, since it is using one USB port cable to connect only.
If is a desktop try using a USB port from the back panel, also in another computer to compare results. If issue persists you can try requesting WD a Power Booster cable. If this does not fix it the drive needs to be replaced.
