Not sure if anyone has seen this probably not but thought that I would throw it out there, running centos 5.4 on a tyan s4985 and I wanted to add a hot swap drive cage to it so I added a supermicro cage and bought some drives, not wanting raid but something for storage and rsync backups. Well I decided to buy some of the newer samsung F3 hd502hj 500Gig hard drives, supposedly good performance for the price since they didnt have enough of them I bought some WD black 500G drives also. Well when I got everything back together I noticed that I was getting errors when centos was first trying to boot, the error was Comreset -16 sata1.... wash and repeat 4 times, then it did it a second time, finally it would time out and and start to boot. Once booted it did not see the 2 samsung drives but saw all of the other drives, didn't matter what channel etc...whether it was in the drive cage or not. I orginally thought it was the bios of the tyan board, which is bad, but to no avail. I finally booted one of the newer buntu livecd and all drives were picked up, so i wonder if it is a kernel issue..if anyone has any ideas or would like more info please let me know....other wise I will need to swap/sell some drives....Thanks.
