Ok here's the deal.

My parents have a Samsung NC10 with Windows XP (Home I think) and from what I could understand they were looking at some photos with the laptop connected to a monitor (for the first time I think, working normally), while downloading the latest itunes and with an ipod connected. Suddenly the laptop runs out of battery, they connected the charger, turn it on and the computer gets into the following blue screen loop.

None of the options work (safe mode, last good configuration, start normally, etc). They all go back to the blue screen.

I looked around and found some pages regarding that.

0x000000ED: UNMOUNTABLE_BOOT_VOLUME
(Click to consult the online Win XP Resource Kit article.)
The kernel mode I/O subsystem attempted to mount the boot volume and it failed. This error also might occur during an upgrade to Win XP on systems that use higher throughput ATA disks or controllers with incorrect cabling. In some cases, your system might appear to work normally after you restart.

From what I could understand doing a checkdisk should fix it but I dont know if it can damage the data.

The most important thing here is the data. The laptop is worthless and they can just buy another one (thats what they told me).


Continuing, its a netbook so no optical drive. They never connected an external optical drive on in too.

Also, they told me after that, while charging, the charger was getting very very hot, way hotter than normal (dont know if thats relevant here). It still works though (computer boots with no battery, connected to the charger).


Now some questions.

Any way to boot an XP with recovery console using USB (I dont know if that netbook supports USB booting, how can I check that out?)
-OR-
If an external DVD drive is connected (for the first time ever), will the bios recognize it and would I be able to boot a Windows CD from that?

Will a checkdisk damage the data?

Can I remove the HD, connect to some other computer and copy the files?

Any way at all to get all the data back?


Any help is appreciated!
THANKS

UNMOUNTABLE_BOOT_VOLUME error usually means hard drive problem.

Since it's netbook, use USB stick to...

Run hard drive diagnostics: http://www.tacktech.com/display.cfm?ttid=287 (or http://www.bleepingcomputer.com/forums/topic28744.html)
Make sure, you select tool, which is appropriate for the brand of your hard drive.
Depending on the program, it'll create bootable floppy, or bootable CD.
If downloaded file is of .iso type, use ImgBurn: http://www.imgburn.com/ to burn .iso file to a CD (select "Write image file to disc" option), and make the CD bootable.

NOTE. If your hard drive is made by Toshiba, unfortunately, you're out of luck, because Toshiba doesn't provide any diagnostic tool.

Chkdsk is not designed to damage data, it can recover some data from damaged file systems or hard drives.

The simplest way to recover data files...if the file system isn't screwed up...is to remove the hard drive from the computer...and then attach it to a secondary system, as a secondary drive (connected directly to motherboard or connected via USB 2.0 device).

The specs show that it has a SATA hard drive, so any device like one of these would do:

Example 1

Example 2

If the 2d system has SATA connectors, then you would not need an enclosure/docking station. SATA connectors are the same on laptops and desktops, despite the difference in size of the hard drives.

<<Any way at all to get all the data back?>>

You never know untily you try. If the hard drive iteself is damaged, it might be tricky...but can probably be done.

FWIW: Should you decide to run the chkdsk /r command on the hard drive while it's attached to the second system...you may save some frustration and unnecessary action.

I can't answer your other questions...but others here can :thumbsup:.

Any netbook should have that possibility. Check BIOS.
