Just so you know, these Maxtor ATA 100 cards are actually PROMISE ATA 100 cards. It has the name Promise written right on the card. Or at least mine does, I bought the Maxtor one.
I also discovered the latest Promise ATA 100 driver works better than the Maxtor driver. I was having problems with my computer waking up after not using it a while, but then switched to the Promise driver and haven't had the problem.
