11. Data Backup(Copy) and Verify
This chapter represents the ‘Copy’ and ‘Verify’ functions.
Insert a memory card into the corresponding memory slot.
The slot for CF/MD/SDHC/SDXC/MS is located on the top side of the NVS2501.
The slot for the SxS card is located on the left side of NVS2501.
The Cardbus memory card (including P2/P2E cards) must be used with a CardBus
memory card adapter which is included in the NVS2501 box.
The Ikegami GFPAK flash memory device can be connected via the “eSATA/
USB-Host” combo slot using the USB cable.
When copying from a memory card, the NVS2501 must not be connected to
a computer. The NVS2501 can copy a memory card onto the internal hard disk via
the built-in memory slot or via the "eSATA/USB-Host" combo slot connector
with a USB cable. After the backup, the copy procedure can be verified. The data
on the memory card and the data on the hard disk are compared with one another.
This ensures that the data has been copied properly (“Verify”). You can choose
the “New Copy” or the “Verify” function according to whether the contents of
the memory card have been copied before.
● Do not connect more than one memory card or USB external HDD to
the NVS2501. Only the first one connected will be detected.
● Insert the memory card carefully. The pin may get bent if you insert
incorrectly.

When you choose the verify function, the NVS2501
compares the data stored on the hard drive to that
on the memory card. The verification logic entails
a full bit-by-bit verification, and detects any
differences.
: For verification, press the control key briefly
: Another option: press the control key for more
than 2 seconds. Select to make one more copy
of this memory card.
Two options are available for verification using left/right key selection.
Sample verify
Full verify
Compare first 1MByte of each file.
All the data is compared
Compare data stored in the hard drive to the data stored in the memory
card.
Verify
Copy again. Make a new folder and copy all of the data in the memory
card to the hard drive.
Copy
Delete the data on the memory card so that it can be reused. Delete
The data on the memory card is compared with
the data stored on the NVS2501 hard disk to
determine whether it is new data or if the data or
a portion of the data has already been stored on
the NVS2501. According to the comparison result,
the NVS2501 operates as follows:
Make new folder and copy all the memory card data into the folder.
Before copying data, the NVS2501 verifies that its hard drive area is
safe. If a bad sector is detected, a new, safe area is found –
then copying [Fast Copy] will begin.
Fast Copy
Verify&Copy
Same as [Fast Copy] but after copying, the data on the memory card
is compared with the copied data in the NVS2501 hard drive. Each
bit is verified.
Safe Copy
(2) Memory card with copied data
If the memory card was copied before and not modified since, then you can
choose to [Verify] or [Copy] or [Delete].
Three options are available for copy using up/down key selection.
