[BBLISA] software hard disk recovery

[Rob Taylor]

I've never used it, but I've heard of spinrite. Runs under windows and supposed to be easy to use.

One of my friends windows machine died today – boots up only half way through the windows splash screen and freezes. There is one file he wants to recover out of it, but it seems to be suffering from hardware failure because attaching the disk via USB enclosure to another computer will only let him load the USB mass storage device, and won’t go any further than that… 



So my question is … 



What are the software hard disk recovery applications that people like, which may save his file(s) and/or his dollars for him? 



Of course, free is awesome, but commercial might be ok too.

If the file system is not mountable, there are various Linux tools which can be used to scrape through a large pile of bits and reassemble files (they work better when the sectors are consecutive). However, I haven't used said tools for several years as they are much less certain than backups.

I then ran WD's drive maintenance software as a requirement for warranty return and their software managed to repair the drive. I have put it back in service in a non-critical RAID and it has worked perfectly for 6 months or so since the repair.
