Help Formatting\partitioning a memory stick pro duo in ubuntu

[Solstar]

Let's start by saying that i'm not 100% knowleageable of Ubuntu,but i know my way out.fact:

1)i have a memory stik pro duo,16 gb,that i used for psp gaming.i sold my psp and i need to get back the stuffi have on this stick

2)if i plug said mem stick on my win 7 pc,it can't be recognized.it never did,and its an original sony one.any other mem stick pro duo up to 8 gb,are recognized perfectly in win 7.

3)on my old psp,it was recognized perfectly

4)when i plug it in win 7,it asks only to format..and the only format-size i can get is 3 gb..thus losing the other 13 gb

5)i have a program that can recovery apps and stuff from mem cards,but of course if i use it on this stick,formatted on win,i will only recover 3gb of data,and i need the rest

so what i did was starting up an ubuntu session on vmware.in there,the memcard is recognized perfectly,but here's the deal:

basically,it states that there's a partition of 3 gb(created by win 7)and 13 gb unpartitioned.i tried to format the mem stick in ubuntu,and again it will only create 3 gb...

so i tried to delete the 3gb partition,and\or tried to create a bigger one with the remnant gb,and here's the error i get

what can i do?

I don't think you can partition stuff while one (or more) or those partitions are currently mounted.

Try:

sudo umount /media/disk

ok done ,but it still format at 3gb..and won't let me allow deleting that partition..

What hardware are you using to read it?

You could try getting a different memory card reader

 

[Solstar]

its a normal ide memroy card reader that plugs on a dektop pc,on the case itself,not one of those external ones.and as i said it works perfectly with all other mem stick pro duo

EDITk i used a sony official tool formatter...now i finally get 16 gb in ubuntu(still 3 gb in win7).is there a program for data recovery in ubuntu?

testdisk/photorec

 

[Solstar]

when i launch testdisk \photorec it still says that the media is 3gb..and halfway during the scan it just stops by itself...

Try testdisk first, to see if it can recover the whole partition ?
