I recently sent an inquiry to this list about fdisk being unable to seek
one of my two basically identical disks. Both are Western Digital 250Gb
disks.
Unable to seek on /dev/sdb
This disk operates just fine when booting Fedora Core 6. However, as
soon as I boot Fedora 9, I get the above error. testdisk seems to
think /dev/sdb is only 137gb, and hdparm confirms something strange.
Here is the output from /dev/sda, which is operating correctly in Fedora
9:
[EMAIL PROTECTED] ~]# hdparm -I /dev/sda

Here is the output from /dev/sdb:

device size with M = 1000*1000: 137438 MBytes (137 GB)
Why is the LBA48 size not the same for both disks, and how can I correct
this?
