Abstract

A computer-based method and apparatus transfer files from a source media to a destination media. In one embodiment, the presence of a source media in a source storage drive is detected. In response to the detection, a user is prompted to transfer files from the source media. Then, in response to user input, files are transferred from the source media to the destination media. In another embodiment, a user is prompted for a transfer session identifier. Data is then transferred from a source media to a subdirectory on a destination media. The subdirectory corresponds to the transfer session identifier. The method and apparatus aid in migrating computer data from one storage technology to another (e.g., from media based on an older technology to media based on a newer technology).

Claims

1. A computer-based method for migrating data between storage media of different types, comprising:

a) detecting presence of a removable source media of a first media type in a source storage drive;

b) in response to said detecting, automatically prompting a user to transfer files from said removable source media to removable destination media of a second media type in a destination storage drive, said first media type is different than said second media type;

c) automatically selecting all files stored in said removable source media for transfer to said removable destination media;

d) in response to user input, automatically transferring said all files from said removable source media in said source storage drive to said removable destination media in said destination storage drive by performing a raw data read of said removable source media thereby creating an image of all data in said removable source media;

e) creating an index of said transferred all files in response to said user input, said index comprising a plurality of keys for one file of said transferred all files, each key of said keys respectively matching text within said one file; and

f) storing said index on a local hard drive of a computer system which communicates with said destination storage drive holding said removable destination media and said source storage drive holding said removable source media.

2. The method as in claim 1, wherein:

a) said removable source media is a floppy disk; and

b) said removable destination media is a compact disc.

3. The method as in claim 1, wherein detecting the presence of said removable source media in said source storage drive comprises detecting an insertion of said removable source media into said source storage device.

4. The method as in claim 1, further comprising:

a) searching for files on said removable destination media based on said index stored on said local hard drive; and

b) locating at least one file based on said searching.

5. Apparatus for migrating data between storage media of different types, comprising:

a) a program memory; and

b) a data transfer application comprising program instructions stored in the program memory, said program instructions defining;

i) a user interface that prompts a user to transfer files from a removable source media of a first storage media type;

ii) a storage source media detection function for detecting said removable source media in a source storage drive and, upon said detection, automatically displaying said user interface;

iii) a data transfer function, said data transfer function automatically selecting for transfer to a removable destination media of a second storage media type all files stored in said removable source media and automatically transferring said all files from said removable source media to said removable destination media, in response to user input to said user interface by performing a raw data read of said removable source media thereby creating an image of all data in said removable source media, wherein said first storage media type is different than said second storage media type; and

iv) an indexing function, said indexing function creating an index of said all files transferred by said data transfer function, said index comprising a plurality of keys for one file of said transferred all files, each key of said keys respectively matching text within said one file, said indexing function storing said index on a local hard drive of the apparatus.

6. The apparatus as in claim 5, wherein said source media detection function reads a status of a bus line, said bus line indicating a change in media presence status in said source storage drive.

7. The apparatus as in claim 5, wherein said source media detection function comprises program instructions for issuing a status query instruction to said source storage drive.

8. The apparatus as in claim 5, wherein said indexing function is configured to receive a filename of said one file and to return said keys in response to said filename.

9. A computer for migrating data files from media based on an old technology to media based on a new technology, comprising:

a) a first drive for receiving removable media of a first type;

b) a second drive for receiving removable media of a second type, said second type is different than said first type;

c) a data transfer application configured to automatically detect a presence of a removable source media in said first drive and to automatically prompt a user to transfer files from said removable source media to said second drive in response to an automatic detection of said presence by said data transfer application, said data transfer application further configured to automatically select for transfer to a removable destination media in said second drive all files stored in said removable source media and to automatically transfer said all files from said removable source media to said removable destination media by performing a raw data read of said removable source media thereby creating an image of all data in said removable source media, wherein said data transfer application further creates an index of said transferred all files, said index comprising a plurality of keys for one file of said transferred all files, each key of said keys respectively matching text within said one file, wherein said data transfer application stores said index on a local hard drive of the computer.

10. The computer as in claim 9, wherein said data transfer application is configured to automatically select, in response to said automatic detection, said removable destination media in said second drive for receiving the transferred files.
