Unknown Partition

By rpevley ·
I have recently installed a 160 GB Seagate Baracuda Hard Drive. I cloned my old 30 Gb's image onto the 160. When I booted it up I noticed that my computer only sees 135 GB of it.

I have a Dell Dimension 300 Bios Version: A02 So, I thought the reason that the HArd Drive was only showing 135GB is because I needed to update my BIOS. I went to Dells website and downloaded BIOS Version: A03. When I rebooted my system it was still recognizing 135GB of the Drive.

I went to Disk Management and noticed that the extra space that wasn't showing up was listed as an unknown partition. I right clicked on it and the on;y option I had was "Delete Partition" the other options were grayed out.

My question I guess is should I have updated my BIOS before I installed the Drive, or is there a way for me to get this "Unknown Partition" usable?

Any Suggestions????

I did a search on TR's Home tab

by OnTheRopes In reply to Unknown Partition

Using the search terms "partition manager".<br><br>

I'm familiar with Norton's PartitionMagic 8.0.<br> PM could be used to delete the unknown partition, and resize the active partition to fill the unused space. The drawback is the cost as it's unavailable as trial software.
One of the results from my TR search leads to here:<br><br><br>
I've never used Acronis software but I see that a trial is available. It looks to be able to do everything that PartitionMagic does and if you want to buy it it's $20.00 less. <br>
I don't know if it's a full-featured or crippled trial.<br><br>
Without my reading the search results in depth I can't say if there is another, more direct, solution to your issue.

The Hidden Partition

by Jacky Howe In reply to Unknown Partition

I am betting that it will have your preinstall OS in there. If you just delete it you will not be able to recover the PC. Unfortunately the larger companies don't ship there PC's with CD's. That is how they are installing software for you that you probably wouldn't dream of installing yourself.

I wondered about that. Perhaps a CIO/CTO can explain it to me.

Why would his original 30GB drive use 25GB for a recovery or preinstall OS partition? <br><br>
My Dell had a recovery/restore partition until I deleted it. It didn't show as an unknown partition. I can't remember what file system it used and don't care to find it in my archives but Windows and Norton identified it correctly. I recall it being less than 5GB in size for a 300GB HD.<br><br>
The only times I recall seeing an "unknown partition" error was when a GRUB bootloader was in the first partition and/or the MBR was messed up for some reason.<br><br>
Edited for clarity.

You're right

A recovery part will identify itself.

In this case, the original "saw" itself as 30 GB. It opened its eyes only partially to "see" the new space.

Part Maj or similar will fix the issue.

PM could expose that things aren't what they appear to be.

by OnTheRopes In reply to You're right

I'm kind of, sort of, curious as to the "clone" tool too. I use Nortons Ghost (the version escapes me at the moment). <br><br>

Though this is after the fact, it might have been better to setup the drives as Master-Slave so as not to lose any existing recovery partition.<br><br>

Having a computer with data that you want to retain without having OS installation disks and verified backups is like walking on thin-ice. You <i>might</i> make it okay but I'll say, "better you than me".<br><br>

hidden partition could have possibly been corrupted. I have had clients PC's where they have been exposed and written to. had the original drive been looked after IE: defrag & dskchk. Was there a currupt area on the drive that was cloned?
There is a risk that you take when you clone older drives.

Not NT

Compaq and Acer are just two companies that i know of that install the XP OS to a FAT32 environment. There was no reference to NTFS in the original Question.

dawned on me your PC shipped with 98 Disk Management is in XP. Was this an upgrade or a fresh install? If it was a fresh install what are the steps that you took to perform it?

By the way i never was any good at maths. Not to quick to catch on sometimes as well.
