Harddrive Needs formatting? after 4 months of use, worst hard drive i've had

re: my problem posted 2 posts ago (April 2012)

i found another clue as to what might be the problem

testdisks reports a strange geometry and says that geometry must be set right before Analyze can be successful.

my geometry is very unusual

model number:

WDBAAK0010HCH-00 1911B

this makes it the 1TB version I believe.

testdisk reports geometry as:

Drive J: - 738 GB / 687 GiB - WD My Book 3.0 1123

CHS 1441517568 1 1, sector size=512

cylinders 1441517568

heads 1

sectors 1

sector size 512

how do I find the correct geometry for this model of harddisk to key in manually into testdisk and re-Analyze again?

thanks!
