What is a "capacity restore tool"? Did it come with the hard drive? Is
this an program that usurps the MBR bootstrap area to load on hardware
bootup and before the OS loads? To the rest of us, that is called a disk
overlay manager. It compensates for an old BIOS that only supports 28-bit
addressing of 512-byte sectors for a maximum size of 128GB (which many
folks call the 137GB boundary in decimal); 2^28 * 512 = 128 GB. The disk
overlay manager provides for 48-bit addressing to get past the 128GB
addressing limit in the old BIOS. Check if there is a flash update to
your old BIOS.
Alternatively, to eliminate problems with motherboards in some old BIOSes
that only supported 28-bit addressing, the hard drive's PCB came with
logic that would limit the size of the partition to only 128GB. You used
a jumper to configure the drive for the max partition size. You never
mentioned model numbers of the 160GB SATA hard drives.
You also never mentioned which operating system you are using. I believe
SP-2 for Windows XP eliminates the needs for the disk overlay manager.
Windows 2000 required a patch. Vista supports drives over 128GB in size.
That is, even if the BIOS doesn't handle the large drive (which means you
will have problems using DOS-mode utilities), the OS can handle them okay
providing there isn't additional restrictions enforced in hardware.
However, you might still require a partition manager to enlarge the
partition. Depends on how the OS got installed.
Is this what you referred to as the software:

What they refer to as "your BIOS does not support LBA48 mode" is talking
about 48-bit addressing support (for LBA mode). If so, it is possible
they installed a disk overlay manager but they leave it very vague as to
what actions their software will commit. That means you don't know what
it plans to do to "fix" the problem, and you are blindly using the tool
(the same way that many users blindly use registry cleaners).
You never bothered to mention how the "drives" became ANYTHING. Your
system crashed. Okay. So was magic involved getting your system back up?
You did some type of restore. Maybe a fresh OS install. Maybe you used a
restore disk. Maybe you used a restore image in a hidden partition (and
you just wiped out that hidden partition by including its space in the
other partition that you enlarged). But then you never did bother to
provide any details, like the operating system, either. Looks to me like
user error when restoring your system by whatever means you used.
