I've had this hard drive for over two years now. A week ago, it decides to slow down to a crawl in Windows - even after doing the usual things to fix it (disabling Superfetch, closing programs, etc.) and it still was extremely slow. I decided to wipe the hard drive clean in a linux live cd (dd if=/dev/zero of=/dev/sda bs=1M) and install that distro of linux (Ubuntu). It fails to partition the ext4 system. I tried wiping the drive and installing Windows again, but it won't let me (either in UEFI or BIOS). I had checked my smart data and while the SMART health passedthe raw value of the command timeout is suspiciously high - 5,227,170,103,295 to be exact. Is this bad for my 1 TB hard drive?
