I have (by trial and error and brute force) determined a valid geometry for this drive under linux that is compatible with 98's concept of */240/63 geometry. The number of cylinders should be 1826(/240/63). at 1826/240/63 I can put every sector that fdisk can see on the drive into partitions, and I can do 'dd if=/dev/zero of=/dev/hdaX' to the partitions without having kernel I/O errors on the disk. At 1827 or higher, I get errors. 1826*240*63*512 = 14135869440 bytes (14.1 GB in HDD manufacturer's terms of K=1000, M=1000000, G=1000000000)... so the size looks sane as well. So... my personal problem is resolved, in that I can fix this with a kernel commandline param of "hda=1826,240,63"... but the bug still exists... why can't linux detect the drive in the first place..? assigned to dledford, Cc: Alan |
