Fsck
From NMTWiki
Easy and suitable for everyone.
As far as I know this works for A200 and A210, but I have no experience with C200
After having many painful issues with my current PCH internal HDD (errors & I/O errors) I decided to run FSCK, which is a check-disc program for linux formats, eg. EXT2 and 3, of which PCH uses.
This is not an advanced How to section as I'm a n00b at linux and I only use windows and I managed to figure it out.

1. How to run Linux on your windows PC.
To do this an easy option is to run a Linux Boot CD on your PC. You can use any of the standard Linux Distros or the likes of gparted which is purpose built for these type of operations. Here I'll use Ubuntu so click here to download a copy of UBUNTU. This is an ISO image file that can be burnt to DVD or CD.
Place this disc in your computer (or even better, a laptop next to your computer) and make sure your popcorn is plugged in via usb to the unit you are going to check the disc with. When you boot, in the bios screen you need to press the "F" key that is for boot options. My Dell XPS M1530 is F12.
You may now select to boot from your DVD drive instead of your hard drive.
This is now going to boot UBUNTU... instead of windows.
Once ubuntu boots, it may ask "try ubuntu" or "install ubuntu".
select TRY UBUNTU as you dont need to install it
Your windows and hard drive from that computer won't get wiped or anything!
2. How to check your drive name
When you want to check a disc using Ubuntu, you will use something very similar to "command prompt/DOS" in windows, therefore you need to type commands. In order to ask it to check the correct disc and correct partition you need to know its "name"
To find its name, click on SYSTEM (top left) then ADMINISTRATION then DISK UTILITY
Select the correct disc on the left and in the window lots of details appear. You are looking for "device". eg. /dev/sdXX where XX is going to be a letter then a number. (sda1) for example.
The letter resembles the different physical drives where as the number is the actual partition number you want to scan. The A200 and A210 make 4 partitions. The 4th is the "main one" that carries all the media.
Write this down and then close disk utility
3. Running fsck
To run fsck click on the top left and select APPLICATIONS then ACCESSORIES and finally TERMINAL This is the final step and one that may require some deciding.
Typing fsck -yvf "your device name"
eg. fsck -yvf /dev/sdb4 This would scan my PCH usb (as that is drive b) and it would scan partition 4 of that drive.
-y is to say 'yes' to fixing detected filesystem corruption, -v is verbose mode, and -f is to force a check on a clean filesystem.
This section is to your own detriment. In MOST cases the files will be fixed and errors completed with little data loss. If there are 300 errors and you dont use -y then you ahve to click 'y' every error that is fpound over a course of up to 2 hours!
If at this stage you are not allow read/write access you can add sudo before the fsck part which allows it to get access and privelages.
eg. sudo fsck -yvf /dev/sda3 (drive a, partition 3)
4. The actual Run of fsck
FSCK may run over 30 mins or up to hours depending upon the state of the disk. Make sure the computer it not turned off in this time!!! There are a number of steps that occur so you just have to let it go for it.
After i completed my first test of this I had a working disc again. Obviously this is not something that fixes all problems, but as Accident said to me, it may be dude to improper shutdown of the pch after losing power before it was shut down (something im going to keep an eye on from now on)
5. Running the fsck scan/fix on the 100/200 Series NMT
Rather than using a PC and Linux bootcd you can do much of the above using the actual player. Downside is that the player does not have the power of a PC and so the scan/fix may take longer, far far longer if you are using a large capacity HDD. Upside is that there's no removing of the HDD.
- Download the tools from HERE and place in USB thumdrive root.
- Browse to the html (4th filter at Home page)
- Cick on "Disable NMT"
- Click on "Scan NMT Partition" (should only take about 1 minute)
- When finish, reboot.
- Browse the html again, click on "Enable NMT"
- Reboot again.
- Then try out torrent etc. that is in issue.
If still fail, then try "typical setup" to reinstall NMT again.
If still fail, then try 1) to 8) again, but this time at 4) do "Scan Content Partition" instead. (**NOTE this may take hours.)
Good luck and I hope my first wiki post wasnt too bad!! If needed I can get some screen shots up :)
