no sdc appears here , BUT it's appears on /dev/
rootghost-lap:/home/ghost# ls /dev/sd*
/dev/sda /dev/sda2 /dev/sda5 /dev/sda8 /dev/sdb /dev/sdc1 /dev/sdc2 /dev/sdc6 /dev/sdc8

also it appears in proc

ok now , let's see what i've tried
testdisk to check for partitions -- failed
dd to copy data from /dev/sdcX -- provide strange output size
for example /dev/sdc1 is about 15G , the output for dd is 62G+ so i had to cancle it
safecopy successfully made an image for partitons , but can't fix images, can't mount it, can't do any thing with it
and some other tools i've tried and all failed , so any idea ?
