The Master File Table (http://www.ntfs.com/ntfs-mft.htm) When you see this corrupting it's usually a sign of failing hardware (often hard disk or RAM) or a nasty bug.
Do the usual scans with EWIDO, HOUSECALL and the Rootkit Revealer but then find the drive's maker and see if they have a drive fitness test.
But before all this save what you can't lose on some other media or memory key.
About a week ago my laptop started asking to check my C-drive every time I turn it on. At first I let it the chkdsk run, noticing it was only doing 3 stages, (the first three of the normal five stages). Eventully I started getting sick of it so started cancelling it before it got started and just starting winXP-home.
Either way, once I log on (or any of the user accounts, not just my own.) I get a yellow warning sign down near the time display and the message telling me the file C:\$MFT [actually it uses a more distinct dollar sign] and advising me to run the chkdsk utility. When I do, ticking the boxs to fix errors and to repair damaged sections, reboot, wait the 3 hours or so that it takes to finish all 5 stages, I get relief but only until someone else logs in. They then get the same message, but with limited accounts they can't schedule a chkdsk and if I log back on, the same message comes up for me too and I have to go through the whole process again.
I want to swear, so, WHAT THE %@#$ IS THIS C:\$MFT FILE? I can't find it at all so I guess it is missing. And, how do I solve it once and for all? Can anyone help???
I should point out also, that at about the same time this started last week, I also started getting another message that a TIME EXECUTABLE is not working and needs to close. I am given three options, DEBUG (tried it, nothing happens except a fresh copy of the same message reappears), CLOSE (that works) and MORE INFO. the info is that this relates to
AppName:lxbttime.exe, and ModName:lxbtuldr.dll.
Nothing even similar in my start programs list, but in the Programs Files folder I found Lx_Cats but the folder has 3 x XML Documents, a file with the extention .A00 and a file called LXBTCATS.dll and nothing else. I have tried the Remove Programs facility in control panel but it doesn't show up.
I doubt the two events are related but since the problems both started about the same time I could be wrong.
If they are unrelated issues, can I, regards the second problem [with lxbt....], just delete the folder? Would this fix it? Also, any idea what it is? I had noticed it was in the programs list over 6 mnths ago but the problem with TIME EXECUTABLE has only been coming up this past week or so, since the first problem [C:\$MFT] began.
Acer Aspire 3500 Laptop running WinXP Home, Intel Celeron M processor 1.5GHz, 1.5GHz 448MB of RAM. What else do you need to know to help on either or both? Ask and you can have the full system analysis file if you want.
