Hmmmm... I have a single Maxtor 80GB hard drive under RedHat 7.2 (heh, with all the package upgrading I've been doing lately, it's more like 7.3) working fine so far. I use it as a SAMBA server mostly, transferring pretty big media files to and from it (700+ MB).
WHat exactly gives you this error code? The Maxtor diagnostics software or the Linux kernel? This error code doesn't look like your typical Linux kernel panic message...
