I have 1TB Transcend External HDD around 2 years old. In the HDD, there are 3 Partition:-
i) Local Disk (J:) [~90GB] - exFAT
ii) Local Disk (E:) [~400GB] - NTFS
iii) Local Disk (H:) [~488GB] - NTFS
I have a number of .RW2 files transferred from a friend past few months into J: and never opened the folder after few weeks later. Not long after the transfer, I found out that every time I connect my HDD to my PC, it lags my PC to the point that it crashes the Windows Explorer. Ever since, I rarely plugged it in and now I can't convert the .RW2 files to .JPG as the converter said "Could Not Read File". So I tried to do a chkdsk, and this happened.
After "The volume will be checked for bad sectors.", chkdsk took 15 minutes before exiting and did nothing to the disk.
A friend suggested me to use PartitionGuru. Without the HDD attached, the program opens smoothly. But once I plug in the HDD, the program stop responding. I tried leaving the program to respond for almost a day, but to no avail. I guess I should mention that when I want to open the Disk Management, it takes almost 30 minutes to show all the drives details.
I'm not sure what to do as those .RW2 files are needed and my friend who transferred it to me had lost those exact files on his computer.
P/S: There is no clicking sound or any abnormal sounds. Everything works like normal except that it loads slowly on Windows 7, 8, and 10 laptop, and it won't load at all in Windows XP Desktop PC as I've tried to plug it in using SATA cables too. The HDD utilizes a dual USB to a Mini USB.
