Some advice here from a guy that's been doing professional data recovery for
Don't touch Maxtor. Ever. Luckily Fujitsu don't make ide drives any more.
They were worse than Maxtor.
If you have existing Maxtor dirves and can't change them make sure you keep
them as cool as possible.
I would recommend Western Digital or Seagate for IDE drives. Western Digital
make RAID edition drives which are very fast and reliable which I personally
favour for these kind of situations and they only cost a bit more.
