After doing hdparm -X34 /dev/hdc
[root@lcjdap ~]# hdparm -X34 /dev/hdc
/dev/hdc:
setting xfermode to 34 (multiword DMA mode2)
[root@lcjdap ~]# mount /dev/hdc3 /mnt/hd-seagate/
hdc: unexpected_intr: status=0x58 { DriveReady SeekComplete DataRequest }
hdc: status error: status=0x58 { DriveReady SeekComplete DataRequest }
hdc: drive not ready for command
ide1: reset: success
hdc: unexpected_intr: status=0x58 { DriveReady SeekComplete DataRequest }
hdc: status error: status=0x58 { DriveReady SeekComplete DataRequest }
hdc: drive not ready for command
ide1: reset: success
hdc: status error: status=0x58 { DriveReady SeekComplete DataRequest }
hdc: drive not ready for command
ide1: reset: success
hdc: status error: status=0x58 { DriveReady SeekComplete DataRequest }
hdc: drive not ready for command
ide1: reset: success
Gave this err about 25 times...
