Saw a similar post to this... but thought I'd give my problem a shot. It's things like this that keep an IT guy humble (after 20+ years).
My co-worker brought me his laptop as such:
Fujitsu A Series Lifebook Model A6210
First thing I did was to clone the original hard drive to a spare I had via ACRONIS 2013 (this way I can thrash around on the spare whilst keeping the original... uh... "pure").
- It cloned without any errors.
At power on - it boots through Windows Splash screen - then goes black - nothing.
- Hooked up an external monitor with same result.
Opened it up - dusted it out really well, cleaned off and re thermal-pasted CPU, GPU, etc. (the original stuff was dry and crumbly)
Put it all back togehter and powered up
- Chose safe mode and it went through it's gyrations until it hit "blah blah blah computer words FJGSDISK.SYS" where it would hang indefinitely. ** (See below for more on this)
- thought "A-ha!" bad driver perhaps...
I removed the hard drive and attached it to another computer - ran a Trend Micro virus scan (what we use here) - clean
I can get to all the files and so forth - so the drive "seems" physically okay (especially since it's a clone).
I tried to use a WinXP boot disk (legal) and got so far as getting to the console and running the CHKDSK /R - which took almost 3 hours (160GB HDD), said it found an error, fixed it, etc.
No change in result.
Pulled the HDD out again, attached it to a DIFFERENT computer - booted via Safe mode - and same result - it appeared to hang on the FJGSDISK.SYS folder...
I attached again to the other computer - went into SYS32 and changed the name from *FJGSDISK.SYS to " " ".OLD.
- now it just went into a reboot loop. I changed it back in the same tedious old way.
** At one point I setup the hard drive as a secondary drive and then mounted the registry of that drive to disable the FJGSDISK.sys from loading.
- this didn't work either.
SO - I can put the original drive in - boot from a Windows XP cd - but since the CD is Dell OEM - there is no Repair option install.
The whole reason for jumping through these hoops is that the customer has Lotus 123/Notes on the system and needs it - (Really?!!) but of course no longer has the original disks.
