I just wanted to add another data point... in case anybody is interested...
uring my recent spending binge, I also acquired a Hatachi portable external
2.5 inch "Touro Moble" 500GB drive.
Righ out of the box, this is what fdisk tells me about this one:
==========================================================================
******* Working on device /dev/da1 *******
parameters extracted from in-core disklabel are:
cylinders=60801 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=60801 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 7 (0x07),(NTFS, OS/2 HPFS, QNX-2 (16 bit) or Advanced UNIX)
start 2048, size 976766976 (476937 Meg), flag 0
beg: cyl 0/ head 32/ sector 33;
end: cyl 1023/ head 254/ sector 63
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
<UNUSED>
==========================================================================
I can't help but note that both this one and also my new Seagate 2.5" portable
external 1TB drive are pre-partitioned with one partition that in both cases
starts at sector 2048. I suppose that it is no coincidence that 2048 * 512B ==
1 megabyte, exactly.
