Hello. I want to use with DPM 2012 R2 a tape created by Windows 2003 Server backup utility and i am getting the following message:

"The tape in Stand Alone Drive Tape Library Hewlett Packard LTO Ultrium-6 drive at Drive Hewlett Packard LTO Ultrium-6 drive has been written to by another tape backup application using an unsupported physical block size. DPM supports a physical block of 65536 bytes for writing and a physical block size ranging from 1024 bytes to 65536 bytes for reading. So DPM will not be able to read or overwrite the contents of this tape. (ID 24084 Details: When accessing a new tape of a multivolume partition, the current block size is incorrect (0x80070452))"

I read about a utility name mytape.exe that can erase the tape, but i can't find it somewhere.

Can someone help?

Thanks in advance for you replies
