Locked

Seagate HD Recognized but not accessible

By smcheatham ·
I've been slogging through forums to see if this problem
exists but
can't seem to find a way to correct it.

Question: Is there any way to 'repair' a external HD so that
a computer
will recognize it as already being formatted and storing
data?

Here's why...

I have a Seagate 250G external HD
(http://www.seagate.com/www/en-
us/products/external/3.5-
inch_external_storage/) that I formatted to FAT32 when I
got it a year
or so back. It's strictly back-up only, so it has seen
minimal use. I
recently switched to Mac and was swapping the drive
between my
WinXP and Mac 10.5.1 with no problem last week. On
Monday I tried
the same and now, in both PC and Mac, the there's an
error message
thrown asking to reformat the drive. Probably a result of
the plug-n-
play I was doing last week and perhaps I didn't quit in Mac
properly(?).

So I dl'd Seagates free demo for data recover
(http://services.seagate.com/diysoftware.aspx) and found
that the
files are all intact which is no big surprise. The thing is I
don't think I
need to 'recover' I think that perhaps it's something to do
with the
drive just not being fully recognized (it shows up as E: but
unaccessible). The way I think about it, the computer is
expecting to
see the switch OFF but it's seeing it as ON which prompts
the comp. to
offer to reformat in order to set the switch ON.

Any ideas as to how to go about 'repairing' without doing
doing data
recovery? Yes, I know I could spend the $130 at Seagate
for the
software and get my files back...but that would involve
installing their
PC only software on a friends computer and not being
able to use it
again on my Mac.

I can tell you why it's like this and YES you do need to Recover the Data

by OH Smeg In reply to Seagate HD Recognized but ...

With external HDD's they need to be shut down before unplugging them from a computer or the Partition Information of the drive gets corrupted and the computers see the drive as not formatted.

When this happens you need to Recover the Data or the Partition and how you do this depends on the Software chosen and what is actually required.

With any Data Recovery Software there are 2 Distinct types that you can use the First and most common recovers files off a working HDD and may require you to Format the Drive so you can recover the Data. The Second type rebuilds the Partitions Tables/Files and is faster but generally a more expensive option.

Here is a short list of the more commonly used Data Recovery Programs available so you can look at what is involved.

While the last 2 are from the same company they are very different products. Win Hex should only be considered for use by someone who knows Hex Inside Out while Davory is a great cheap General Purpose Application.

Personally I prefer the On Track Option but it's anything but cheap. However because I use this type of software a lot it's paid for itself many times over by now, for a cheaper option Spin Rite from Gibson Research or Stella have both very good reputations by other TR members.
