I've been trying to repair for some time a Sony Vaio PGC-61611U, which as the title says, doesn't boot.
The original error message goes something like this:
Windows has encountered a problem communicating with a device connected to your pc.This error can be caused by unplagging a removable storage device...,or by faulty hardware such as a hard drive or CD-ROM.Make sure any removable storage is properly connected and then restart your pc. File:\Boot\Bcd Status: 0xc00000e9 Info an unexpected I/O error has occurred.
Or sometimes it will also say "Operating system not found". I'm not quite sure yet what makes it go for one option or the other, but it seems to be related with whether the optical disk drive or the hard disk are first in the boot order from the BIOS.
So far I've tried using Knoppix and then TestDisk to repair the boot sector, but TestDisk said the boot sector was fine. I tried using a Windows 7 installation disk and boot from it, but no matter what I do, whether I choose Start Normally, Safe Mode, or Safe Mode with command prompt, it eventually reaches a point with a black screen and a cursor, and nothing more.
I also tried accessing the hard disk from Knoppix, but I got an error that looked like this:
Error mounting: mount exited with exit code 13: ntfs_attr_pread_i: ntfs_pread failed: Input/output error
Failed to read NTFS $Bitmap: Input/output error
NTFS is either inconsistent, or there is a hardware fault, or it's a
SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows
then reboot into Windows twice. The usage of the /f parameter is very
important! If the device is a SoftRAID/FakeRAID then first activate
it and mount a different device under the /dev/mapper/ directory. Please see the 'dmraid' documentation
for more details
So far I've been trying to find some way to run chkdsk /f or bootrec.exe, which I can't do fron Knoppix as far as I know. Ideally I'd like to make the computer work again, but right now I feel I could also settle for being able to access the data (even if it is from linux) and put it on an USB stick, which I can't do directly at the moment.
So, can I have some help with that? Does anyone know what is going on, and how can I fix it or at least recover the data? I try not to make posts about such things, I usually can manage on my own, but my google-fu has failed me this time and with an amateur level of knowledge I don't think I can get much further than this on my own.
EDIT: I didn't post this one in the "Windows doesn't boot" section because it doesn't seem to be malware related, or at least obviously so. The owner of the computer told me that her brother was the last person to use it, and that when she tried to turn it off it said that windows hadn't been shut down correctly, so it must have something to do with a bad shut down attempt.
