I think I'll try another drive first.

If you're willing to start from scratch, I'd use DiskPart and clean the drive and reformat. &nbsp;i had one recently that I would switch back and forth from PC to Mac and it got borked. &nbsp;It's been fine since.<br />
<br />
here are the commands...<br />

Basically, you'll want to list, select the drive and then clean. &nbsp;takes about two minutes from a command prompt.

I have a Windows 2008 server with an External USB hard drive that I use with the Windows backup.<br />
Periodically the backup fails and I repower the USB drive and it goes to Read-Only in Disk Management.<br />
<br />
How can I get it back to normal read/write and stop it from happening again?

USB Hard Drive becomes Read-only randomly

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage

Windows Server 2008 and Windows Server 2008 R2, based on the Microsoft Vista codebase, is the last 32-bit server operating system released by Microsoft. It has a number of versions, including including Foundation, Standard, Enterprise, Datacenter, Web, HPC Server, Itanium and Storage; new features included server core installation and Hyper-V.

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.
