USB Disk management

Assuming the USB memory stick was formated and named disk1

In RouterOS version 6.x the following command sequence worked to rename disk1 to Disk2

/disk set 0 name=disk2

In RouterOS ver7.8 the above does not work .. name= is no longer valid

Can anyone tell me how to rename disk1 to Disk2 under routerOS v 7.8. ?

Are you sure that name is disk1 ?
Mine shows as usb1-part1.

Anyhow, instead of name, use slot (found it using F1 on command line for possible options and verified with GUI/Winbox)
/disk set 0 slot=disk2

See help page: https://help.mikrotik.com/docs/display/ROS/Disks
It’s also mentioned specifically:

Note: Starting from RouterOS 7.7 disks will carry names (slots) where they are physically connected

Thank you ..

You are correct … disk1 is no longer used …the naming convention has changed … it’s like you stated.

What is really annoying about this specific CHANGE is that on many devices the change is transparent – meaning the MOAB control file is stored successfully under disk2 – while on some device like the hAPac2 I have lots of complaints that MOAB control file no longer get stored in disk2 , they get stored somewhere but do not show up in the Files list ??? … so I suspect corruption and will be forced to do a Netinstall if renaming /disk set X slot=disk2 does not work … grrrr
How do I know THAT they get stored somewhere but do not show up in the Files list

The log file states the download was successful … really???

For the hAPac2 the solution was to Reformat the USB memory stick then use
/disk/set x slot=disk2
Then Reformat top most named ID and make sure MBR is left unchecked … this worked to resolve the issue …
