As you have said, the guide is providing exactly that: Changing the File System type into some other format which unfortunately both Windows and Ubuntu can't recognize.
From your screenshot it looks like your Ubuntu can still see the device (/dev/sdc) although Ubuntu can't mount it.
How about changing the File System type into what it was before? (Which I ...

1st Solution: (Tested and Failed)
On a recent Tekzilla episode they recommended a free data recovery application called Recuva. I've never used this application before but it sounds promising. I would however recommend you clone the external hard drive to another hard drive before attempting to recovery your data just to be safe.

A well written program generally won't be writing to its Program Files folder unless you're upgrading / reinstalling. Most programs do their writing to/from various folders in the user's home directory (My Documents, AppData, Temp, etc.). The paging file is wherever you have it configured in windows, and generally applications don't have much control over ...

If you really don't care who writes what where, and assuming the disk is mounted at /mnt/media-disk, then the best way to set full permissions for everyone would be to run these two commands:
find /mnt/media-disk/ -type f -exec chmod 666 {} \;
find /mnt/media-disk/ -type d -exec chmod 777 {} \;
The first command will set read and write permissions for ...

There are such devices. Basicly they are multi hard drive enclosured with RAID.
An example is from icy dock.
It has not network port, but USB, 1394 and eSATA connection options and is idependent of the computer. It is meant more for desk top use, but can easily be transported.
There are many vendors but you could start by looking Newegg icydock raid ...

In general, the class of device you describe would be called network-attached storage, NAS for short; the specific use case you describe can be filled by any number of home- or small-business-grade devices of that type.

Using TestDisk, I discovered that my external HDD had actually been converted to Linux file system. Such a shame that even Windows 8, Disk Management can't at least tell if the hard disk is using a file system created in Mac or Linux.
I managed to back up all of my documents on Windows itself, using DiskInternals Linux.

Yes! I do this, but not every 30 min. There is no compression. But you know how synctoy works so if you want every folder pair or one one it's up to you. Start a windows task scheduler event turn through the menus and here are some tips:
In the Add arguments box, enter –R to run all of your syncs each time.

is the bios recognizing the USB hard drive? Did you install the OS to the ext HD? Or just move the files. The OS has to be directly installed to that hard drive. This one may help as well

For Debian based systems (e.g. Ubuntu etc) there's the usbmount package that automatically mounts USB drives for you. It basically uses a udev based approach as already outlined - only it's just a simple package install. It seems the original author of the package has run out of steam but Ubuntu/Debian still appears to maintain it (I guess it's not that ...

Look at this chart on Wikipedia and scroll down to the last table for "Supporting operating systems." This lists OS support by file system.
As you can see, there is no file system that is covers all OS platforms, the closest being FAT16. FAT32 is a close 2nd, requiring 3rd party driver support for z/OS.
Since you require read/write support and large ...

Hard drives do not use a consistent amount of power. In particular they use as much as twice as much as their "idle" power when spinning up the disk (from power off or sleeping) and more power doing long seeks than doing short ones. So it is completely possible to have a drive that mostly works but has sporadic failures when it is underpowered.
However, ...

There is no perfect solution for all situations. "Best" varies based on your requirements.
I use NTFS on several 1TB USB hard drives for the wide support it has on multiple devices, because I often take them to clients' houses and I know the files will be accessible regardless of the operating system with no extra set up required in most circumstances.

If drive sleep/wake events are logged by default you can check the Windows Event Log for the same. If not it may be possible to enable auditing so they are logged. The most accurate stats might be obtained from the drive itself using its Power-On Hours SMART attribute, provided the firmware excludes sleep time from the count.
On certain drives this can even ...

What is the format? NTFS - FAT32 - EXT3... Are the files copied to the root or do you have a subdirectory tree in place? Some formats have limits on the total number of files you can have in the root regardless of space.

The two USB's are solely for power, not for data transfer. So if 1 USB is capable of powering it (as you have said is the case) then there is no benefit in plugging in the second one.
Situations that would require the second one include:
You are using hardware that the USB ports do not provide as much power as they should (e.g. a battery powered USB ...

I agree with your statement to a certain extent that the hard drive would either work or it wouldn't. I've run into situations where external drives weren't getting enough power and they would make repetitive noises like they were trying to get up to speed but couldn't. My best guess on the two USB connectors is that one is meant for data and the other is ...

USB2 specifies minimum amounts of available power (600 mA, 4.75V, so 2.85 Watt). Your PC probably supplies more than that. In particular, it almost certainly will supply 5 Volt (3 Watt).
That's sufficient for your particular drive. However, there are plenty of drives which require more power. 4 or 5 Watt is quite common. That also means some drives will ...

WinHex is very good at this. However it really depends on whether/what kind of harm was done to the partition map and the file system meta data records.

Someone did some research into how to format a flash drive with udf so it can be used on as many operating systems as possible. His findings are at http://sipa.ulyssis.org/2010/02/filesystems-for-portable-disks/ and there's a script to format the disk properly at http://sipa.ulyssis.org/wp-content/uploads/2010/02/udfhd.pl_.txt

This should work fine. However, to be safe you should probably use a powered USB hub rather than a power adapter as typically used for charging a mobile device as some of them are designed to use non-standard voltage/amperage.

I've not tried it, but it should be ok. the device will only draw the power it needs off the second usb plug.

With Disk Utility, you can only resize partitions (without erasing them) if the partitioning scheme is GPT. Yours is MBR. Also, you can't verify this disk with Disk Utility.
You have some options (always do a full backup before doing anything!):
Erase the whole disk and re-partition it as GPT. In order to do this, you should select the right option (1, 2, ...

If you are planning to use this disc as the actual Linux OS disc, then it will need to have an some sort of ext partition for that. However, Windows Dow not get on very well with ext, so I would suggest formatting a separate partition as NTFS for the general file storage and sharing between systems. When you plug this into your PC it will appear as a ...

What linux system will you install?
Regardless of that, Linux will create it's own partitions. When you install it, it will request space, in the form of unallocated space or a partition it can remove. You select space, or a partition (of sufficient size), and it will create at least two partitions in this space.
To have space for your files, use Disk ...

It looks as if the disk was slowly deteriorating up to the point where critical bookkeeping info got hard/impossible to read. That's why chkdsk now chokes on it (sees it as a RAW disk).
I wouldn't put too much emphasis on HDTune reported 100% damaged; it probably could not access the disk and so failed on every try to read.
The question is: is it only a ...

Most likely the Windows Updates are not the culprit. AutoDesk software has various anti-piracy functions built into their software.

Hey I have encountered the same problem and the solution is simple!
What the virus does is:

The trickiest part is that the shortcut lets you access your files if you open it but will run a background virus as ...

The only component that you really have much to worry about is a hard drive. If you have an SSD the point is moot.
Otherwise, a foot would be more than enough space (This was about average for poorly shielded speakers and PCs / CRT monitors). Although, with decent speakers I have seen more than a few speakers sitting on the PC and there has been no ...

You should have no issues with them right next to each other. All your devices are well shielded. In addition to that, home based electrical devices do not typically generate a large or powerful magnetic field. As for proof, well... There are plenty of HTPC, DVRs, etc that are more than 1000 watts that have hard drives inside them.
As for sound, I ...

When you unmount cleanly (e.g. eject a drive, rather than just unplugging it hot), you're letting the OS do clean up activity to the drive (which prevents the repair dialog you sometimes see when you plug in a drive).
In this case, the drives are probably spinning up to close file handles, write out journaling data if needed, parking the heads, flushing ...

No. You can not connect it through your Macbook to the server for others to access. You have to directly connect it to your server and set it up as shared drive or shared folder. Then others can access it through the server but it would independent of your Macbook.

You could run something like for following CMD script:
:again
dir x:\*.* /S > nul
:: adjust timeout 10s to your requirements!
ping -n 10 127.0.0.1 > nul

But this might shorten the remaining lifespan of your disk as it involves actual read operations.

Would that indicate that there's still something else wrong with the notebook, or can an external faulty hard drive cause a BSOD?
Yes, there might still be a problem with the laptop. Yes, an external faulty hard drive can cause a BSOD. The two are not mutually exclusive. All the BSOD proves is that there is still a problem. The details of the BSOD ...

A hard drive requires a host [computer] to live in. I think any answer you get will depend on what OS/hardware you run, but in general you can just use "Windows Filesharing" [also known as SAMBA, SMB, CIFS] to share the drive, as this protocol is widely used and works with Windows, Mac and PC.
I suspect that reading/writing the HFS+ partition will be a ...

I don't believe you should have any problems whatsoever disconnecting and reconnecting the drive while your PC's hibernated. Since the drive is encrypted using TrueCrypt, for further peace of mind you can ensure that under Settings / Preferences / Auto-Dismount you have the "Dismount all when" User logs off and especially Entering power saving mode options ...

You can disconnect that drive without any problem. People will never use filesystems (or encrypted drives) if this may be dangerous in case of accidentally power loss or disconnect.

When you sleep or hibernate a system any on-going I/O is quiesced. A well-behaved device driver will assure that there are no on-going operations -- eg, any file move operations will be stopped in such a way that overall consistency is maintained, and file directories and free-space tables will be completely written.
Of course, there's no guarantee that ...

Yes it is, because when you hibernate your system your usb connectors have no electricity and a complete image of your memory is inside your HDD.

This is typically due to a power configuration option. Go into device manager and don't allow the computer to put the device to sleep!
If this doesn't work, try playing with the power options in Control Panel

What you're looking for is a wireless USB hub such as this one (disclaimer: I've never used one, that's just the first Google result I found).
On one end, it has USB ports as with any USB hub; on the other end, it has a Wi-Fi radio that talks to your wireless network and exposes attached storage devices. For stuff like USB microscopes, oscilloscopes, ...

No one USB end will be fine for powering the drive and transfering data too.
