I have a Seagate Laptop HDD which I want to format. Since I encountered problems formatting it while installing Windows 7, removed it and connected to PC using USB adapter.
Tried the following:
- Partition manager on Windows (All partitions are deleted; Formatting unallocated space fails after deleting all partitions)
- diskpart.exe on windows (clean) (All partitions are deleted upon completion; But partitions reappear upon reconnecting the HDD with the original contents)
- kde partition manager on Debian/Linux (Shows as deleted; Old contents are retained)
- fdisk utility on Debian/Linux (No change in the partition table)
- dd utility on Debian/Linux (Failed with I/O error)
Please help me fix this issue.
Thanks in advance.
