I had an old Mac with many files and had them transferred to a PC formatted memory stick. I have since attempted to retrieve files and have been unable.
A number of issues could be the cause of this problem. Let’s go through a few of them and see if any of them relate to your situation.
Basic Data Recovery for Macintosh
In order to transfer files that have been taken from a Macintosh without investing in any type of software, you should be able to transfer them to a compatible Macintosh computer. If you are attempting to transfer them to a PC or computer with a Windows -based operating system, you need to use the same type of software program that you created the files in so that the computer will recognize the files and be able to open them properly. If you don’t have the program that you used, then you need to obtain software that will allow you to do so. You can either get a type of emulator that will convert the files or the same software that you originally used, but for the type of operating system that exists on the new machine.
The PC Formatted Memory Stick
If the memory stick has been used after the files were saved to it, it is possible that either the files or the memory stick itself have become damaged. If this is the case, then you might need to use a data recovery application in order to retrieve the files. To check for this, insert the memory stick into the Mac and check to see if the files are visible. If they are, then the problem is not the memory stick.
Data Recovery for Macintosh
If you have been attempting to transfer the data onto a Macintosh, then the problem is most likely with the memory stick itself. If this is the case, you can obtain a data recovery tool to retrieve the files.
Cross-Platform Compatibility for Mac and Windows
Fortunately, software does exist that will allow you to access your Macintosh data on your PC or Windows based machine. The problem with trying to read Mac files on a PC is that the file extensions that are used by the Windows operating system are not used by Mac. What you need is a software utility that will allow you to rename the files so that they can be read. I’ll offer a couple of programs here with pertinent details, but I cannot vouch for any of them since I haven’t used them.
MacNames is one such application, but it is on the pricier side at a cost of approximately $170. It can be used with Windows NT 4.0, Windows 2003 server, Windows 2000, and Windows XP.
Gemulator Explorer is a free utility for reading Macintosh formatted discs on a Windows computer. You can check it out here: Gemulator Explorer.
