I have a 1TB hitachi that after some use develops bad sectors as reported by HD tune and checkdisk. After reformatting the HD tune and checkdisk report no bad sectors.
I use the disk exclusively for my music collection which is indexed by foobar2000. After some time checkdisk is ran at windows startup and many files are found to be "corrupt"... sometimes bad sectors are reported(But not always). Usually it seems it has to do with the MFT being corrupt to some degree(some files were put in the "found.chk" dir and I've listened to them and they were ok).
I send the drive back and got a new one I believe(serial was different) but the same problem occurs. It only happens on this drive. I have an another one I brought at the same time without having these problems.
I believe the issue is foobar2000 corrupting the file system some how but I do not know this to be fact. I only believe the probability of having the same issue between the old HD and the new one to be pretty low and formatting the drive seems to make it work for a while(but of course I have to restore all the files).
I do not want to return the drive if it is ok and just end up with the same issues(although it would point to foobar being the most likely culprit). I've used a different SATA cable and different port without different results.
