External Hard Disk Asking for Reformat After Plugging to Mac

April 10, 2013 at 15:55:49
Specs: Windows 7
My friend plugged my external hard disk (that requires 2 cable) into his Macbook Air, only to realise that the cable doesn't stretch across the computer. So, it was plugged in for a while, did not show up on the Mac, and never got dismounted/removed properly.

So, I went home and plugged it into my Windows 7 notebook, and suddenly the disk is asking me to reformat. I have run crystal disk management tool very recently, and the disk is in perfect health. So could this be a cable issue? Or?

Upon some research, i went to read the hard disk through Ubuntu, and the folders are there, but they are all empty. I am now running Test Disk to see what is wrong, but it is at 1% for such a long time during Analysis. Since it can read all the folder entries, it isn't a cable problem right?

Meanwhile, if anyone has any suggestions. Please let me know. For example, does TestDisk further damage the disk during analysis, or if i should run it from Windows etc.

Thank you!

Look in Windows Disk Management to see if the drive format type is listed as RAW. If so, download and use a utility called Easeus Partition recovery from the link below to repair the corrupted partition.


If you see any other listings other that RAW post back before doing anything.
