Hi. I have a text file on my portable hard disk (WD 250 GB) named urgenttttttttttt.txt you would have already assumed how important this file would be and it is updated daily. The size of the file is 545 kb which is HUGE for a notepad. I opened the file 3 days ago and it gives me an error: "cannot open the K:\Mainnnnnnnnnnn\usb\urgenttttttttttt.txt file make sure a disk is in the drive you specified" There are many text documents in my hard disk and many even in the same folder but every document is fine but there is a problem in this particular file. I recovered this file using shadow explorer but the recovered file is 518kb in size and many new things i wrote in the notepad are GONE. I have some private text in the document or i would have uploaded it on some site for you. I am unable to copy or move this file to other folders. There is another error related to this, I deleted an iso file that was in the same portable hard disk by mistake (even from recycle bin) and tried to recover it using "disk digger" (best recovery software for huge files!!). But I get an error which I have never seen before.. "There was an error while reading from the disk: Data error (Cyclic Redundancy error). How would you like to proceed" and no option works out. I searched google for this error and i came to know that it comes from a bad spot on the hard drive and the bad spot would be because of the same urgenttttttttttt.txt file. Please Help.
