I'd wait to learn if these work on other PCs.
If you wanted to solve the sufficient rights issue, that's on google but for now, try this on a new administrator account.
I have 1 Tb seagate hard disk which was working fine but now when i connect it to my laptop running with windows7,
windows detects the Hard disk and Icon of the disk displays at my computer. But when I double click it to open it shows an error message box " Location is not available f:/ is not accessible Access denied".
And when I see properties by right clicking it is shows
Used Space 0 bytes
Free Space 0 bytes
Capacity 0 Bytes
Also tried to check it for errors from tools It shows error message "The disk check could not be performed because windows can not access the disk"
And also i have to tried to access it from command prompt (Run as administrator) using command f:
It shows "Access denied"
When I try to change access permission from properties/security by providing full control or changing the owner it shows "unable to save the changes in permission information".
And finally when I try to format the disk It shows "You do not have sufficient rights to perform this operation".
<div>And I have
also tested two other external drives(WD & seagate)but faced the same issue.</div>How could this is possible that one day disk is working fine and next day it has this issue.
Please provide some solution to fix this.
