KErrNotReady could happen due to any of the following reasons:

1. Lun is in the process of becoming ready
|
|
502 |
2. Initialising command is required
|
|
503 |
3. Lun is not ready to process the command - meaning it is still handling
|
|
504 |
the previous command
|
|
505 |
|
|
506 |
KErrUnknown could happen due to any of the following reasons:
|
|
507 |
1. Mass storage device does not respond to the selected logical unit, other
|
|
508 |
than the locial unit not ready scenario 2. The command sent was not
|
|
509 |
recognized or contains a invalid code 3. Invialid field in the command block
|
|
510 |
4. The requested logical unit is not supported
|
|
511 |
5. The mass storage device cnosists of insufficient resource
|
|
512 |
6. Hardware error
|
|
513 |
7. Blank check
|
|
514 |
8. Vendor specific error
|
|
515 |
9. Any illegal request (we assume the commands sent by MSC should be
|
|
516 |
supported by the device, if not then the illegal request is said to be of
|
|
517 |
unknown system wide error for Symbian. 10. Miscompare - we do not support
|
|
518 |
the compare operation/command so this error should not happen
|
|
519 |
|
|
520 |
KErrAccessDenied could happen due to any of the following reasons:
|
|
521 |
1. Data protection error happened
|
|
522 |
2. Media was write protected
|
|
523 |
3. Media was not present
|
|
524 |
|
|
525 |
KErrOverflow could happen due to any of the following reasons:
|
|
526 |
1. Data over flow occured
|
|
527 |
2. The requested LBA is out of range
|
|
528 |
|
|
529 |
KErrAbort could happen due to any of the following reasons:
|
|
530 |
1. A copy operation is aborted.
|
|
531 |
2. The command is aborted
|
|
532 |
|
|
533 |
KErrCorrupt could happen due to any of the following reasons:
|
|
534 |
1. The underlying media was having errors
|
|
535 |
|
|
536 |
KErrDisconnected could happen due to any of the following reasons:
|
|
537 |
1. The media was changed/removed - While this error is happening the file

extension will be notified setting the iChanged flag
