I have been testing/using ATI 10 at the workplace. Nothing sophisticated - just an Ibm thinkcentre PC - pentium 2core running winxp. It's a fairly new PC with SATA drives (Hitachi made i believe) I have been running the most basic routines like backup & restore on the single drive. There is no raid or scsi - just using IDE Channel. Sometimes the backup (to external WD or external Maxtor via USB) will stop halfway no matter WD or Maxtor. But if i persist a few times more - it might succeed. Similarly ,with restore. Sometimes it freezes at different points 12 minute mark or 17th-minute mark... it just freezes. At other times - when the linux boot loader starts up - it cannot find the external maxtor drive. My take is that - it doesn't matter which make you use - maxtor, WD, seagate etc you will face the same problem with the loader software. At the moment i have rebooted the PC 8 times in a row (using rescue CD) because it cannot detect the external maxtor... It is scary restoring a PC this way because if you are in an emergency situation in need of important data or application - it will surely draw sweat beads on your forehead.
