....a bad sector in a drive isn't bad at all. This happens a lot and is nothing important really. What sucks is that this may be in the MBR of the drive and you need to rebuild it. Google/Bing/whatever rebuild MBR and leave that Linux disc out of the picture for now. You had a simple update, you swear you did nothing else, and now it won't start...it's fixable as long as you don't get hamfisted.
.... Something as simple as SpinRight can get your data corrected....
This is Free clinic stuff as it's help requested. We talk about how awesome the next hardware in 2015 will be here usually.
You are correct, this would be better if it were transferred to the Free Clinic (moderator?).
Bad sectors are always bad news
on ATA drives.
I wouldn't let that ancient Spinrite
in my house much less my PC. Even Gibson expresses surprise people still clamor for it. It was awesome in MFM days when tracks strayed. It is useless on ATA drives as sectors are scanned/tested and rewritten during idle times by the drive itself (and dangerous in data recovery situations where writes are the last thing you want to do).If
it is a corrupted MBR then Testdisk
can help (and is on Parted Magic
as everything else is). And Linux is an important resource for Windows
rescue, recovery and repair---actually it is always the last resource too as it can succeed when Windows OS disk, recovery disk and BartPE/WinPE fail. Though it is true you should always first backup a drive image if possible. And then ID the problem before ANY write attempt (including a repair) is attempted. It is also true the data is almost always still there as long as you don't overwrite it. Whether you can get it off the disk or not for free is another question.
I noticed several zombie threads resurrected quite recently by Mr. Chumley. Please stop.
