Once i turn on the drive i havn’t paration appear but when i enter by “fdisk” i discover that my partations are the same but the PRI-DOS partation has system “unknown” (not FAT32 or other) i don’t know why my FAT is changed. I try to delete the PRI-DOS partation and creat a new one but the same Problem appears. my data is in the Extanded partation and i can’t try any thing else because my data is very important. Please help me to solve this problem or tell me how i can get my data from the extanded partation.
