How to retrieve files from a drive needed to be re-formatted?

Healer
I have a portable drive that has some files in it. Somehow all of a sudden the files in there are not visible or retrievable. Connecting it to a computer USB port, I can only see a message saying the drive needs to be formatted.

If I follow the prompt to format it, I can imagine I would lose all the files in there. Is there any way I can go around it? I wonder!

Sorry, let you know how what works?

It has 2 USB Plugs which plug into 2 different USB Sockets on the Computer to give the correct Amperage to the External Drive.

Each USB Port by Design is supposed to supply 5 V DC at 500 Milliamperes. That is the Apple design but with the move of USB to the PC some makers think that they know better and have reduced that 500 Milliamperes. Granted this mostly happens with NB's and is claimed to increase Battery Life by their maker but it's a Short Cut which hurts the system and really shouldn't be taken. It also occasionally happens on Desktops where that USB Socket is in a Fly Lead so read that as Front USB Sockets and the like.

If you carefully look at a Y Cable you'll see that the Middle Connector has a standard Cable but the Cable to the second USB Plug is thinner than the other cable. This is because the second USB Plug only supplies the Current to drive the external drive so it has fewer wires in that part of the lead. There are no Data Wires just Power Wires.

You can plug one of these cables into 2 Different USB Sockets on a computer or into 2 different USB Sockets on a Powered USB Hub. If you do not use a Powered USB Hub you are not getting the full benefit of the Y Cable as there will not be enough Amperage available at the Hub.

I hope that helps you understand.

This is a very good explanation. Thank you!

I have a question about the data recovery utility above asking if such utility does not require hard drive be formatted.

I applaude all those who replied with information on how to recover data. Kudos to you all for sharing your experience. However, this "Y- Cable" issue is another story.
Per the USB specs (USB Power Delivery Specification Revision 1.0 Version 1.1 dated 31 Octobber 2012 available @ www.USB.org), section 2.3 states in part <i>"There is only <b><u>one</u></b> Source Port and <b><u>one</u></b> Sink Port in each PD connection between Port Partners."</i> The purpose of this statement is so the Source port can advertise its' capabilities to the Sink port and the 2 ports can properly negotiate all necessary power issues (including "low-power" devices).
By using the Y-Cable applying 2 Source ports, you <i>may</i> temporarily get around a problem <b>IF</b> the issue is insufficient power. However, you have also just told all the non-electrician techie-wanna-be's how to potentially damage otherwise perfectly good equipment.
In future, I suggest that <b>IF</b> you give out this kind of information, please also include any & all necessary caveats. In my 30+ years experience, I have found that only telling part of the story frequently is worse than not helping at all.

My computer speed has been greatly compromised after I having been getting the message High Disk usage from the Norton Antivirus. I have run basically all the maintenance procedures available all the informations obtained is that everything is working okay but my computer continuously freezes and becomes unresponsive most of the time. It is really a nightmare for me and since i not have much knowledge on these troubleshooting issues I am really stranded. Window experience index has degraded from 5.9 to 2.9 but when I run it using HP troubleshooting tools the window experience is always 5.9. I do know that with microsoft troubleshooting tools the information is correct since my laptop has slowed down tremendous even if I had only use 388GB free of 444GB for local disc(C:). How do I solve this problem since I have already tried to restore it the date that it was working properly but this turned out to be a useless exercise.

Your have to start a new thread.

Perhaps re-install the computer from scratch might help you.

I had the similar situation. The device was used on a MAC and it got unusable on a PC. What I did was that I formatted it and then used the RecovrMyfiles program to recover the data. I was able to recover every thing from tha USB device.

Wouldn't it have been easier and considerably faster to

Just install the Partition Type that is used by the MAC onto the PC so that the Windows OS could read the MAC Drive?

Hi Col,

Is Partition Type a piece of software to be installed on a PC for use by MAC?

Are you also saying that data recovery utility software doesn't require drive to be formatted before lost file can be recovered?

Thanks!

No by default Windows only reads Windows Partitions. When you plug a External Drive or any Storage Device into a Windows Computer it needs a Windows Partition Type on it to be readable.

To get around this it's possible to install a piece of software that allows the Windows System to read different Partition Types. There are several of these but the most commonly used is Mac Disc
