I have a Samsung SP0802N ATA hard drive on an HP Pavilion a500n desktop. A while ago it stopped booting, after the "HP" blue BIOS screen, instead of GRUB (the linux bootloader) I only get a flashing bar on the upper left corner and nothing happens.
I have an NTFS partition which I am unable to mount in the ubuntu live cd, and I had an ext3 (or ext4, maybe) partition which I was able to mount and access the files. Since then I formatted the ext3 partition to an ext4 partition but I have not been able to reinstall Ubuntu in that partition.
Also, I enter disk utility (from an Ubuntu Live CD) and in SMART status I get a green dot saying disk is healthy but when I click on SMART Data and run a short self-test I get the message "Failed (Electrical)" after just a few seconds. Basically there are three things with which I am having issues:
■Diagnose the problem and determine if the HD is at fault and whether it is still usable.
■Recover data on the NTFS partition
■If HD is still usable, reinstall ubuntu, or at least boot Windows XP in the NTFS partition.
I should also add that Disk Utility does not seem to recognize the NTFS file system (It is shown as Unknown 49 GB on the graph), but when I attempt to install Ubuntu it does recognize the partition's file system as NTFS, also when I run fdisk -l. I am following these instructions (under Using Linux to recover your Data) but the command "mount -t auto /dev/sda2" tells me I need to specify the filesystem, so when I run "mount -t ntfs /dev/sda2" I get "The device '/dev/sda2' doesn't seem to have a valid NTFS."
I greatly appreciate any advice. Thanks!
