Re: Problem Formatting an External hard drive



The drivers I referred to would not reside ON the external drive,
but would reside in the windows operating system. They tell the
system how to access the drive. IF there are drivers, they
should have been supplied on floppy or CD with the drive. They
may not be required, which might explain why there are none on
the CD.
If there is no "install" components other than the backup
software, then you probably don't need drivers.

I do know that, to be recognized, a hard drive does have to have
an MBR (Master Boot Record) written to it. Usually the MBR is
written when a partition is created. In my experience, which
isn't great, fdisk is the program which creates partitions and
prepares the disk to be formatted.

Here's a link that may help you:
http://support.microsoft.com/?kbid=313348

It talks a lot about prepping a disk for the OS, but all the
other uses are mentioned there too, along with a couple good
links such as:
255867 (http://support.microsoft.com/kb/255867/) How to use the
Fdisk tool and the Format tool to partition or to repartition a
hard disk

Give those a read and see if it doesn't help.

Until fdisk, or its equivalent, has been run, it's my
understanding that hte disk is not yet ready to be formatted.
fdisk must come before formatting.

That's what I thought. But the CD that came with the drive
doesn't seem to have any drivers or tools - just a program
for doing backups. Nor does the Iomega support web site. In my
Windows XP Add hardware wizard, Iomega isn't a listed
manufacturer.
But in general, if the drive is now unformatted, and
"un-partitioned" wouldn't I have to first get Windows to
recognize it before I could add any drivers? It seems to
me there must be a way for Windows to access a completely
clean drive.

Try and remember that when you originally formatted the
drive, if you use some IOMEGA tools. I know when I had a
Zip drive under Windows 95, I had to use Iomega tools to
set it up. Also just thinking out loud.

I've long had an external 80GB Iomega HD connected to
my WinXP home system via
USB. It was formatted into two equal sized partitions,
and has functioned
without problems for several years. I wanted to
transfer this device to another computer. So first, I
wanted to wipe both partitions clean, then create a
single NTFS partition. Here's what I did: I went into the
Computer Management section and deleted
each partition. But
when I tried to create a new portion and then format
it, I ran into a problem. Windows XP now does not
recognize the HD. I tried the Control Panel |Add
Hardware, and looked into some help files on Iomega's
site. But still no recognition.

I'm certain this is a software issue, as the drive has
functioned perfectly
until now.

Is there a simple step I've overlooked?
