Hi all,

Encountered an issue when attempting to resurrect a 22 year old system.

On initial start-up the CPU gave overheating beeps. Sorted that out with a spring clean but major issues have since reared their ugly heads.

To get forward with solving them my first query is if TestDisk can be run from a FD as that is now the only means to gain pc access. The download in zip form is too large to fit on a 1.44 media. Therefore, is there a core component that I can extract which will operate from a FD even if there is not enough room to include boot files?

cheers,

Kev

Telling the name of the operating system would be more helpful than telling that it is 22 year old.

Do me a favor and replace your abbreviations by full words. In 10 years nobody will know what "FD" should stand for!

I don't know why but my reply of a few days ago seems not to have made it!
So, re-post. Result after a scan:-

Analyse Disk80 - 4507 MN / 4298 MiB - CHS 548 255 63
Geometry from i386 MBR: head=255 Sector=63
Should be marked as Fat16
get_geometry_from_list_part_aux head=255 nbr-16
get_geometry_from_list_part_aux head=8 nbr-2
get_geometry_from_list_part_aux head=16 nbr-2
get_geometry_from_list_part_aux head=32 nbr-1
get_geometry_from_list_part_aux head=64 nbr-1
get_geometry_from_list_part_aux head=128 nbr-1
get_geometry_from_list_part_aux head=240 nbr-1
get_geometry_from_list_part_aux head=255 nbr-16

Partition table type (auto): None

Analyse Disk81 - 4507 MB / 4298 MiB - CHS 548 255 63

This was originally a dual-boot system and fdisk shows a 8 MB partition for this purpose.

Even after reading some of the program's documentation I'm still unsure how to change the table to Fat16.
