all my hdd's are iBM , with one exception a maxtor 40gb disk, that is crap...very bad.., it overheats in this summerheat, the ibm disks have no probs at all.
(the maxtor is now resting, refused to work one day due to heat..)
i have 120gb ibm's , 80 , 40 , 46 , 20 and 10gb disks , none have been a prob in the amiga, but i must add i have always used some sort of 4way adapter and now lately i use fastata from elbox.
also, the 46gb disks and several more from ibm are the ones u should stay away from, i mananged to fix one of em (why i have it) as my friend gave it to me as it refused to work..
cheers'
pps:maxtor, if u buy it...buy a fan for it also.
