 Posted: Sat Mar 27, 2004 6:46 pm Post subject: Hard Drive Geometry is wrong |
 |
|
I have 2 identical hard drives, IBM 75GXP 45gigs. The first hardrive has boot, swap, / and /home on it, while the second hardrive is just a 33 gig fat32 drive with winxp on it. Yes, just 33gigs. It does not and will not recognize the full 45 gigs. And yes, i tried multiple paritions, I can use any combination of 33gigs!
I checked somethings out and came up with some interesting points
The "broken" harddrive has 255 heads, 63 sectors, and 4111 cylinders, while the other "working" harddrive has 255 heads, 63 sectors, and 5606 cylinders. These were reported by cfdisk and fdisk.
I figured that I could just use fdisk and change the 4111 to 5606, reboot, and it would register as 45 gigs, but it does not. I have also tried hardcoding into the bios, but that didnt work. Then i tried selecting none in the bios and seeing if maybe it was passing off the parameters, but that did not yeild any more space ethier.
Here are the outputs of hdparm -I /dev/hda and /dev/hdb

Maybe the MBR is corrupt? - can you afford to loose everything on the disk?
If so, try ...
dd if=/dev/zeero of=/dev/hd? bs=1k count=1
... and then re-fdisk it
That will completely wipe the boot sector |
