Hi,
I bought this disk and reformatted it to exFat in windows7 to be able to share data with my wive who's on a macbook. I read about this on different websites, so I gave it a go. I used the standard cluster size.
Afterwards, windows recognised the HD, but only for a couple of seconds. I tried on USB 2 and 3, didn't make a difference. Sometimes the disk was recognised, sometimes not. And I was not able to copy anything.
After some testing, I decided to reformat it to NTFS. In windows, I could get all the way to the format button, but after that, nothing happened. Tried different PCs (didn't try mac) and different programs to get the disk going - Find and Mount and EaseUS Partition Master. Both were 'not responding' after I pressed format. I was not able to close the program as well. So I had to close them with the task manager as there was no progression after 30 minutes. Maybe that made it worse, but I didn't see another option..
Now I'm trying HDD low level format. First program that seems to do something. But after 80 minutes it has formatted 310.000 sectors of the 4.000.000.000 512 byte sectors. 0.0MB/S..
I was planning to buy the software to make it faster, but the problem is clearly elsewhere.
Any suggestions? I'm stuck here for 26.000 hours, and I have to go to work tomorrow
