However if you have used a Time Capsule made by Apple then this is a WiFi router with a built-in network Time Machine server and this would be encrypted. Note: If a Mac backs up to a network Time Machine server instead of a local hard disk then it will always be encrypted, however your friend is unlikely to have used a server to do this so it would not apply. There are several utilities available to let Windows read (unencrypted) HFS+ volumes, below are some of them. To do this will however require installing additional software for Windows to let it understand HFS+ format partitions.

No while it is certainly true you are not going to be able to read an encrypted Mac disk on the Windows PC, it is possible to read a Mac formatted but non-encrypted disk on Windows. This means it will likely be partitioned using the GUID scheme rather than the Master Boot Record scheme, and also that the partition/volume will be in HFS+ format and not FAT32 or NTFS. It is possible the drive in this case is despite what you are currently thinking not encrypted, it will however be formatted as a Mac compatible hard disk and not as a Windows compatible hard disk.

Most people would not need to encrypt it. Time Machine when backing up from a Mac to a locally connected hard disk allows you to chose whether to encrypt that hard disk or not.
