First of all why did you do all this, surely you should have realised that you would possibly break your player. There is being curious but you were just plain reckless. Curiosity does not go as far as to reformat a hard disk when you have no idea as to the original format or what the player requires.
However, with the drive back in the LIve Hub can you see the disk under the disk manager setting.
System Setup / Disk Manager. If you can see the disk, then select it and re-format it using the Live Hub. Hopefully the player will again recognise the disk and you will be back in business. If not then you have expensively learnt not to take things apart that you don’t understand.
