之前有台外接磁盘，原本的主系统是BSD6.2
目前主系统重灌为BSD9.2，但原本的外接磁盘却挂不上来
该外接磁盘的 fdisk 讯息如下
******* Working on device /dev/da0 *******
parameters extracted from in-core disklabel are:
cylinders=486305 heads=255 sectors/track=63 (16065 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=486305 heads=255 sectors/track=63 (16065 blks/cyl)
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD)
start 63, size 3812497542 (1861571 Meg), flag 80 (active)
beg: cyl 0/ head 1/ sector 1;
end: cyl 1023/ head 254/ sector 63
The data for partition 2 is:
sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD)
start 3812497605, size 3999992220 (1953121 Meg), flag 80 (active)
beg: cyl 1023/ head 255/ sector 63;
end: cyl 1023/ head 165/ sector 59
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
<UNUSED>
但使用 bsdlabel 却都错误讯息如下
bsdlabel: disks with more than 2^32-1 sectors are not supported
请问该如何让我再把原本的两个磁区挂上来呢?
