Hello, I've had a 1.5TB Freecom external HDD for a few years now (has Samsung innards I believe) and it has worked great since. About 2 days ago, I tried to write some files to the drive, but it won't write at all. I can read fine from the drive and disk checking utilities all report that there is no bad sectors on the drive. There is definitely no permission problems. I also have done a deep format, checked different file-systems (NTFS as well as ext4). I have also created a new partition table (msdos(mbr) and gpt) to no avail. Is there any more tests I can run? Should I get a new HDD? Thanks for the help in advance.
