I have a Samsung Spinpoint F1 750GB (HD753LJ) that is quite new, I only got it on 27 Feb 09. Okay I am going to try and write exactly what has happened and everything I know so far as to provide as much information in the hope that someone can provide me with some help. First off windows media player started having some issues playing back my music which is stored on the drive in question. I restarted my PC to try and sort of WMP. After the reboot I launched WMP and tried to play my music but it said that it could not locate the music files in the directories. I then tried to access my D: partition on the drive in question and it said that the hard drive wasn't partitioned. I ran Check Disk on D: and basically it went through and found lots of errors (lots of 'error in index $130' messages for what seemed to be every single music file I had). Then it tried to 'recover orphaned files' some files it seemed to be a success, but it seemes to fail on every single music file I had, saying that there was 'insufficient disk space to recover lost data'. After Check Disk was completed I could access my D: partition again and everything seemed intact apart from my Music & Software folders which said they were empty. I could not access these folders. Upon attempting to access the folders it would say that the disk was not formatted and ask if I wanted to format it. I attempted and succeded in recovery the data from my Music and Software folders by using 'EasyRecover Professional' and saved the data to my F: drive. The data seems to be fine from my initial investigations. But now I am stuck with folders on D: that are said to be empty, but do actually contain data as I was able to recover it. I cannot delete these folders. When I try and delete them I get a message saying 'Cannot delete Music: The directory is not empty.' and if I try and delete it via CMD (command "del d:\music") I get 'Data error <cyclic redundancy check>. The folders are not infact empty as I have said I could recover data from them. And D: says it has an amount of free space that indicates that it is including the files from Music & Software folders in this calculation. I am very confused, is it a physical problem with the hard drive? It would be strange if it was as it seems to be contained into only 2 directories (D:\Music\ & D:\Software\). Check Disk is still coming up with the same errors if I run it again on D: What should I do? Is there are like any more hard drive analysis software that I should run? Should I just atempt to return the hard drive?
