If it's corrupt, it will get scanned automatically I think, Slackware 9 here does. Then you do get the opportunity to run fsck which is the File System ChecK tool. This can take a while and take several passes to get it right. Yes, I got caught on this too, can't remember how. If you get back on long enough to do real backup, a rebuild has its uses as you never know which bit got corrupt and is there like a time bomb waiting to blow you away when you do something different to normal. Patching any kind of file allocation table is a chancy affair leading to the loss of a complete or significant part of a file. It takes a lot less than a whole allocation block out of a binary to wreck it and make its operation very risky and unpredictable. I don't know the low level workings of Linux to know if it has duplicates of allocation tables, even DOS used to though don't know about the Winglows. GA!
