i have an external harddrive Seagate FreeAgent GoFlex 1TB. it stopped giving me access as i wrongly manipulated the right click, properties, security and took off all the allowing accesses, it sound silly, as it was really stupid. now, when plugged my computer shows " Access denied, you need to format" I have 8 years of research in this hard drive, my computer is a Windows XP. thx for your help in advance
