I have a backup HDD that is connected via eSATA. When I turn it on, my PC's HDD light turns on solid. It sits like this for about two minutes. Then the PC's light turns off for about 30 seconds. It then repeats this 2 more times before my backup HDD shows up in My Computer. So it takes about 5 minutes or so from the time I turn on my backup to the time I can access it. About 2 or 3 times the PC will lock up, but then unfreeze during this waiting period. I have noticed some conflict with my wireless connection while all this is going on as well. Sometimes I find that disabling the wireless will speed up the wait time. My computer will not boot up with the backup HDD on, it will freeze at the WinXP loading screen. Works just fine when using the USB connection, just not eSATA. What's going on here? Can this be a power supply issue even though the external has it's own supply?
