Finally got it working...

Under putty --> Telnet
Disable "Retuen Key sends. Telnet New Line instate of ^M"

That will fix the prompt things and I can do the fdisk now..

Formatting now...
let see what happen next.

Hum... No success story...

After I reboot ...

I really have no idea why it happen....

I just do the fdisk.
mkswap /dev/sda1
mke2fs -j /dev/sda2

I'm on windows xp.

when you do the resize on part 1,2 if you have two disks setup in raid 1 will that maintain your Raid setup? it looks like it will and I'm in the same boat as dcmwai with the same drives -- not that I have an issue re-formating if required but am I correct in assuming you can just do a resize of the partitions instead of formating?

TimeZlicer thanks for your help on this.  I have a WD20EARS and DNS-323.  

I tried doing the partition myself using the steps you laid out but my 4th partition's numbers didn't match.  I didn't think anything of it and comitted the changes and rebooted.  Upon reboot the drive light is showing up purple, so looks like it has corruption.  Not a big deal since no data on it, but what do you think I'm doing wrong.  Here's my fdisk results.

Code: [Select]

The number of cylinders for this disk is set to 243201.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

did you mkswap partition 1, format partition 2 and run hd_verify before you reboot?
if not, surely you will get some error,
because the data in the original partition 4 is assuming that partition 1 and 2 are already formated
(i assumed you have chosen ext3, if not drop the -j option in mke2fs
Code: [Select]
mkswap /dev/sda1
mke2fs -j -m 0 -T largefile4 /dev/sda2
hd_verify -w

in your case you can use 2088456 for partition 2
Code: [Select]
ceiling(2088450 / 8) * 8 = 2088456

You're right, I didn't format the swap and 2nd partition.  I was able to successfully execute the mkswap command but the mke2fs (yes, ext2 so no -j option) yields that the partition is still mounted and I can't format.  How do I go about formatting it?  I tried the -F (force) option but that didn't work.

if you have created partition 2 correctly using fdisk,
this should be able to format partition 2 as ext2
Code: [Select]
mke2fs -m 0 /dev/sda2if you still face problem, please post some transcript,
or it would be difficult to help you
