My hard drive suddenly crashed today. I run SMART monitoring software, but there was no warning. I wouldn't be so worried about it if my backup wasn't five-days old (my backup software is supposed to run every hour, but apparently it wasn't...).
Sometimes, my computer gives me the error "2100:Detection Error on HDD0 (Main HDD)". Other times, it's able to get a little further but fails to find a bootable partition. I dual boot Windows and Ubuntu; it never boots Windows, sometimes it's able to boot Ubuntu, but irrecoverably hangs out after a minute or two.
Similar story when I connect it to a USB SATA adapter. Sometimes, it will mount, but it will suddenly become inaccessible and dismount after a minute.
Is there anything I can do for data retrieval at this point or do I need to take it to a specialist if I really need the data?
