SD Card problem missing file /conf/nodes/UN0032.bin

[rayg]

My backup is failing because it cannot read this file /conf/nodes/UN0032.bin.

My previous backup is a little old but the zip does contain that file.

In order to change my SD Card and eventually migrate to eisy I need a successful backup.  

Is this the correct forum to ask this Question?

Can I:

1- Somehow manually copy that file back onto the existing ISY SD Card?  Should I do that with Telnet/FTP OR possibly by accessing the SD on my windows computer and adding the file (it is FAT right)?

2- Can I somehow get the ISY to re-create all the node files and hope the SD card remains usable enough to perform a full backup after?

Failing that I will recover the older backup and re-apply what is missing/changed

Thanks for your help

Try the windows computer route:

• Copy the files off the current card, taking note of every file that it can't copy because it can't access it, but click continue each time so it keeps going
• Find those in the unzipped backup and replace them:
  • If its more files than nodes I'd come back here and list them
• Copy the updated file set on a new card
• Hope that it works, you'll want to verify devices afterwards

The card is FAT 32, but scroll to the second post here were it's recommended to format the new card on the ISY via telnet

Thank you Paul.  I will try this in the next few days and report back.  Also, thanks for the heads up on using ISY to format.

Q1: Now all I have here are 32GB cards that meet the standard.  Will it be able to format those and simply ignore the additional space?

Q2: Also when copying missing files to the existing SD to get things going again leading to a successful backup, will the file system or SD Card be smart enough not to reuse bad sectors (sorry for the old disk drive talk)?

Thanks again

Isy can take a max of 16GB. You'll need to buy a new 16GB

No. Create a fresh file set on your PC by copying the contents of the old card there. For the files it can't copy, take note of file name and directory.

Then unzip the backup on to your PC in a different location. Use the list you created to repair the file set on your PC by copying from the unzipped backup location on the PC.

Then copy the results onto the fresh card.

Thanks Paul.  Turned out to be slightly different solution.

When I loaded the SD into a Windows folder the file copied over just fine but was ZERO bytes

I did read that the ISY can handle a 32GB SD cards.  Are you sure about what you were saying about needing a 16GB max? 

I had to reset the Location to my timezone as it had reset itself to the default Pacific.  Same thing for my custom Admin name and password, it got reset too.  I am not sure why this happened with the new SD in place.  I assume those override settings must also be stored on the SD card?

Anyways, your advice appreciated and marked as the solution but it would be nice to read thoughts in the SD Card size and these seemingly phantom resets of the properties.  With a solid backup I am in a better place to upgrade to Eisy now, just have to wait for a sale.

Thanks and Happy Holidays.

From the UDI Wiki

The ISY994i takes a MicroSD card. The max size is 32GB. Please look for a card with the newer A1 rating (A2 also works, but will fallback to A1 because the ISY994 does not provide hardware support required for A2).
