tried lots of stuff.
gpart n all that
finally gave up & delete the dam thing.
any here is what win xp did.
i had a win xp partition, linux partition(s) & 60 gb unused space. tried fdisk but it didnt work. so booted into winxp (thats the biggest mistake of my life) and created a logical partition in free space (extended was already allocated) 52 gb of fat32. big big mistake.
win xp didnt warn & did it happily. formatted it to fat32.
rebooted into linux - and boom !!!
all sort of freaky partition errors.
booted into win xp & omg - it shows me more than 10 partitions of 900 GB !! OMGGGGG WTF ??????????
tried all sort of recovery software - but of no success. lost lots of data. ..tried recovering from backup superbocks and all that - but it didnt work
formattted everything & back to zero.
I AM NEVER EVER GOING TO USE WIN XP OR ANY OTHER HIGHER VERSION OF MS SHIT !
Win98SE & maybe give win 2000 a shot
Maybe this will warn other users - never work around with critical task on win xp.
