Recently I purchased two 500GB FreeAgent external portable hard drives and when I plug them both in, my computer only recognizes one of them. The other stays offline and disk management says:”The disk is offline because it has a signature collision with another disk that is online.”
[multiple passports — signature collision]
I wanted to solve this issue, so that I am able to have both drives plugged in and accessible. Fixed by right clicking that message over “Offline” and selecting Online.
Solution is very simple. follow the steps given below:
1- If you have administrative rights go to START button, and right click on “COMPUTER” and Select “MANAGE” or find MANAGE on your system.
2- In this window, select from left side ” Disk Management ”
3- You will see your drives on the right side. (HERE YOU SHOULD SEE YOUR NOT WORKING DRIVE, ITS APPEAR AS OFFLINE) you may have to look around for it , should I say look down to find it, the drivet may not be on the right it may be below the disk list, look around and down
4- right click on “OFFLINE” tag and select “ONLINE”
5- Good to go…
Let me know if your problem is solved using these steps.
