The hard drive on my XP desktop was filling up, so I moved data to a 200 gig Maxtor external hard drive, which now has way more data on it than C: can hold, and I'm running programs like iTunes directly from the external G: drive (the program is on C:, but the data is on G:. For back up purposes, I got a 2nd Maxtor external HD (300), with the idea of copying the data from G: to F: Whether I START XP with both drives running, or start XP and then start the external drives, XP sees both hard drives. However, when I try to copy files from G: to F: using explorer, it won't work. Explorer will open G: and let me highlight and copy a folder, but as soon as try to access F: to paste the folder, the (+) sign next to F: DISAPPEARS, and the drive cannot be accessed. The same thing happens if I use SyncToy instead of explorer to sync or echo files on the 2 drives.
The only way I can back up from G: to F: is to copy a small AMOUNT of data from G: to C:, then turn off G:, turn on F:, copy the data to F:, turn off F:, turn on G:, and copy the next batch of data.
I've checked disk management, and both drives are there, and HEALTHY. Utilities show them to be functioning fine. Independently, they work fine. Together, nothing.
Any ideas on how I can copy from G: to F: without copying the data to C: first?Well Heres my two sense. I have the same sort of problem when I plug my USB DVD Burner into my computer, when I plug it in the USB Network Adapter no longer WORKS. Reason being is that the DVD Drive takes more power, and probably uses more resources which means both can't run at the same time. I'm assuming the same thing is happening with you.That's what I feared. I was just hoping someone had a work around. Thanks anyway.Are those external hard drives powered by an AC adapter or only from the USB ports?Both are powered by AC adaptors.Do you have anything else plugged in?
Other USB devices?Quote

:-? Do have a comment, question, or just rambling?

An HP Pringer and a Belkin backup battery.
If you're suggesting that I disconnect them both and then try it again, I'll give that a try and let you know what happened.
