External NTFS Hard Drive 160GB( Samsung make) suddenly appears as RAW format and is now unreadable.
I had an external USB drive which was working along nicely for over a year, Now, it has suddently become unreadable and windows is asking if it be formatted.. I don't know what to do. I connect it to two different PCs and both cannot read it.
Try running CHKDSK /F DRIVE LETTER: This worked for me when an internal Hard Drive went RAW unexpectedly. CHKDSK revealed some errors which the F command "Fixed" but all data remained intact and the drive now is OK.
