1155703 2010-11-22 23:50:00 Got XP Home HP Pavilion here that was working fine and after a reboot stops with BSOD and reboots. Will give the option to load Safe Mode and stops at MUP.SYS and reboots.

Have taken the HD out and plugged into an external USB SATA enclosure and the C: drive wants to be formatted and is not accessible. The Recovery partition is OK and accessible.

Put drive back in the HP and will still boot as above.

I have booted off XP cd and used recovery console and C:\ is not accessible so can’t check disk etc. When trying to do a repair install it shows the C:\ as unknown.

I believe the drive is faulty but I am unsure why it starts to boot when the drive is not accessible using the above options?

Any ideas?

1155704 2010-11-23 00:01:00 Chances are the the partition has become damaged and the OS system files are damaged/ destroyed.

Boot the PC from a linux live CD, something like Ubuntu and see if it will see the contents so you can copy it off to a portable USB drive.

If Ubuntu wont see the contents, there are other options.

DONT what ever you do try to do a repair install -- theres a 99% chance all the data will be wiped out.

1155705 2010-11-23 00:04:00 The hdd / file maybe corrupted. Why it stops and reboots at mup.sys. Whats the BSOD stop error? Is the hdd itself SATA as well?

Have you got another PC with XP on it?? if you do, connect it to a working system, and copy mup.sys to it. See if it boots

1155706 2010-11-23 00:49:00 Wainuitech - should have tried the linux CD but can't find it so downloading now and will give it a go. Will let you know what I find. berryb (99)
1155707 2010-11-23 01:33:00 No luck with Ubuntu. Reports Unable to Mount - MTFS is either inconsistent or hardware fault.

Other options??

1155708 2010-11-23 04:17:00 Since its unmountable, you may have to use somew data recovery software to recover the data.

Depending on how important the data is will depend on if you want to spend some $$ on recovering it.

Personally I use Get Databack (www.runtime.org) -- the trial version works to the point of actually recovering the data.

You would attach the HDD to another PC as a slave or Via USB, then run the program from the working PC over the drive - it will take a while depending on how much data is there. Once finished it shows the explorer tree with all the folders, yu select what you want and it copies it to where ever you tell it to.

There are free programs available, some are betterm than others, but I prefer to use something I know generally works, esp if a scan can take 5-6 hours sometimes.

1155709 2010-11-23 07:37:00 OK will give data recovery a go.

What I am still unsure about is why the HD will boot when in the HP but is not accessible via the other options I have tried. If the partition is dead it shouldn't boot.

1155710 2010-11-23 07:40:00 Usually if you put a hdd in another system, and you want to access it, you have to take ownership of it (support.microsoft.com) Speedy Gonzales (78)
1155711 2010-11-23 07:50:00 The partition wont be dead, but it "could" be damaged.

Heres what I mean - in plain English.( hope this makes sense)

When you boot with the XP CD, it see's the Drive, it can see its formatted as C: BUT cant see the rest of the files due to corruption. Thats why you get C:\ as unknown.

IF the system files are damaged there may be a dead spot.

Take the following numbers as an example: 0123456789

Lets say number 2 is damaged, it will read 01-3456789.

The spot you get to in safe mode, MUP.sys is in 01 - The rest of the system files and data are in 3-9, but cant be read normally because theres a dead spot #2.

Windows more than likely wont see it either when the drive is attached as a slave or Via USB, as its looking for the full path.
Ubuntu throws a wobbly by saying its unmountable because it can only read 01 dead spot.

A data recovery program will see past the dead spot and allow recovery (hopefully)

1155712 2010-11-23 08:06:00 I have used Recuva before but found it abit clunky but did the job I was after.

I have downloaded GetDataBack and will try it. Have you found it better than Recuva?
