Recently, I went to "My Computer" meaning to check my CD ROM drive, in error, I clicked on "Check Local Disk" it started, so I let it run, it came up "Scan for, & attempt recovery of bad sectors" I said OK,& it went through Phases 1,2,3 & 4 in twenty minutes, then "Disk Checked". I clicked on OK. Since then, when I boot up, within a minute, the dialler is there, & in next to no time, I'm on-line, before, I had to go to Internet Explorer or Outlook Express before the dialler would appear, tell me it's not a coincidence, what exactly does this facility do? I know the "Scan for....etc., IS self-xplanatory but how? & has anyone else tried this,.....I guess they have. Also it said "Check Hard Drive & check Local Disk", I'm still learning as you can gather, so what is the difference please? Another facility was "Automatically fix files system errors" should I have done that too? Hope this isn't too involved, but it IS all on the same subject Thanks.
