comment Rescue data from damaged hard disk
@Lexsys: Thanks. I think SpinRite goes much deeper, by going below the sector level and by the deliberate relocation of the drive's read/write head. gddrescue has a different philosphy, trying to do as little work as possible on the damanged places in order to reduce the risk of total failure. This is a valid argument; SpinRite's operations can push a drive over the edge and that could happen in your case. But on average I think SpinRite is much better.

comment Rescue data from damaged hard disk
@Lexsys: Partial recovery of a sector is supported (instead of discarding the entire sector). From grc.com/srrecovery.htm: " ... with this "mostly correct" now-readable sector so that all but a few data bits of the file can still be read and used. This is obviously a huge improvement over losing the entire file due to one of its sectors being completely unreadable.

comment Rescue data from damaged hard disk
@Lexsys: I found a more accurate reference, grc.com/srrecovery.htm: "During the defective sector re-reading, the drive's read/write head is deliberately relocated to either side of the troubled sector -- and at varying distances -- so that when the head is again placed over the troublesome sector, it might come to rest at a slightly different position than it did last time ... and might allow the sector to be perfectly read."

@Lexsys: there is a very detailed description of how SpinRite works in this document: grc.com/files/technote.pdf, "SpinRite. What's Under The Hood."

comment Rescue data from damaged hard disk
@Lexsys: I don't know about gddrescue (I found packages.debian.org/sid/gddrescue) - do you have a reference to a good description? SpinRite tries to influence the physical movement of the read heads over the damanged sectors in order to get the right read signal that will allow correct reading of the sector. It is in-place recovery - data is written back to the disk in case the reading of the bad sector succeeds. It may try up several thousand times on the same sector.

Does it work? From the Wikipedia article: "Junction points can only link to directories on a local volume; junction points to remote shares are unsupported."

comment Need help with putting Cygwin on DVD for a offline install
If my memory serves me right: I think this question has now been changed. It appears as if we (Joshua Nurczyk and undersigned) don't answer the question, but we did at the time (just instructions for offline install). (I will do some research and delete this comment if it turns out not to be the case).
