from any kind of memory cards)
z With maximum speed of 20MB/sec and average speed of 14MB/sec, it only takes about 1
minute for Nexto-M1 to back up 1G bytes of data.
z Nexto-M1 has verification feature that you can double check the integrity of your data.
z You can install large sized HDD into Nexto-M1. Most of legacy devices can only manage
HDD size less than 120G, but you can install maximum of 2000G bytes HDD into Nexto-M1.
Things to be careful
z For Nexto-M1 to work properly, 2.5” PATA type HDD must be installed. Without HDD, Nexto-
M1 will not work properly.
(※ Nexto-M1 doesn’t match with SATA type HDD
z HDD is fragile to magnetic field and impact. So be careful not to drop Nexto-M1 or place it
near magnetic devices such as TV, radio or speaker. The company will not be responsible
for loss of data stored in HDD under any conditions.
z Nexto-M1 has many slots for variety of cables and memory card. Do not let dust or foreign
objects get into those slots.

name like YYYYMMDD.XXX. Nexto-M1 checks the files and extracts the latest creation date among
the files and use to name the folder. The 3 letters of suffix is version number of the folder in case
same date comes up more than once among the backup files.
For example, if the latest file creation date is 2007-10-25 then new folder 200071025.000 is created
for backup.
[Caution] Every time you backup, even for the very same data more than once, new folder is created
and no data is over written.
When backup fail.
When Nexto-M1 fails backup data properly, Tmp folder is created. In the Tmp folder, it appears all the

Here, press the button once to verify the data.
There are 2 types of verification.
Press the button once for Sampling Verification or press down
the button for Full Verification.
With full verification, Nexto-M1 compares every bit of original
data and backup data, so it takes longer time to verify.
With sampling verification, Nexto-M1 compares only sampled
bits, so it takes less time to verify.
Once verification starts, you will see the number of verified files
and number of to be verified files.
When done, you will see the message shown in the picture.
Remove the memory card to end the process.
Backup the same card more than once.
When you insert the same card more than once, you can choose to backup the same data again.
Even if you back up the same data, Nexto-M1 will not overwrite the existing data, instead it creates
new folder and backup the data in the new folder.
Insert the same memory card, here press down the button to
choose “more” command.
Here you can backup the same card once more. However you
can only choose “copy” method. “move” method is the option in
this process.
You can always go back to initial screen by press down the
button for more than a second.
You can see the number of files copied and number of files to be
copied.
When you backup the same data more than once, Nexto-M1 creates new folder every time. First it
creates folder named 20070421.000 then 20070421.001 and so on.
So existing data remains in the different folder.
