hdd geometry
After a failed HDD sfdisk refuses to copy the partitions:
Warning: given size (1459904512) exceeds max allowable size (1459901185)
Disk /dev/sda: 750.1 GB, 750156374016 bytes
255 heads, 63 sectors/track, 91201 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk /dev/sdb: 750.1 GB, 750156374016 bytes
64 heads, 32 sectors/track, 715404 cylinders
Units = cylinders of 2048 * 512 = 1048576 bytes
sda is the new one, sdb is the old one, active in raid.
Size is the same, but geometry no... It's safe to change geometry to match the old one?
Comments
Geometry doesn't matter in the year 2015 and it haven't mattered for years. It's all LBA now.
thanks, fixed by specifying geometry:
sfdisk -H 64 -S 32 /dev/sda
i never liked math...
