Can I edit hard drive contents with the SCFS extension?

You cannot do it directly from the command line. However, you can save the content you are interested in to a disk file, edit it with a third-party hexadecimal editor and then write it back. However, the best way to do it is create an access descriptor, start the Memory Juggler and edit hard drive contents directly from the Memory Juggler’s hexadecimal editor.

How do I create an access descriptor?

To create access descriptors please use the HDAD command. This command can display a list of created access descriptors as well.  It also removes access descriptors on demand.

Can I clone my hard drive content to another drive using the SCFS extension only?

Generally, yes. If you want to clone small data arrays (for example, a flash card), you can use the RWS command to save an image to a disk file and then restore the data to another flash card. But if you need to clone very large disk arrays, you will need to use the Memory Juggler as it allows writing data directly from one data source to another without intermediate storage.

Does the SCFS extension have a limitation on the hard drive size?

No. All existing hard drives can be processed with the SCFS extension without size limitations.

Can I use the SCFS extension to process data on flash cards?

Yes. You can process data on flash cards the same way as would do on the hard drive.

What is the difference between the DPE and the DVE commands?

The DPE command displays information about all hard drive areas including unpartitioned areas. On the other hand, the DVE command displays only partitioned spaces and volumes of your hard drive. In addition, the DVE command displays letters of existing volumes.

How do I view hard drive contents?

With the help of the RWS command you can read/write/view hard drive sectors. Please use –v switch of this command to view hard drive contents. The RWS command also allows writing hard drive contents to a regular disk file and vice versa.
