Hi All,

I thought it might be a good idea to create a backup image of the ISY’s card, so that if something went wrong I could just drop in the backup (or, being hundreds of miles away from it, have my only neighbor do so). It seems wise to use a card that’s as close to the original as possible, but I need to order it soon and am not near the unit right now. Can anyone tell me the card size (SD, microSD, etc), memory size (8GB, 16GB, etc) and speed (e.g., C10) of the card used in an ISY 994 purchased this past summer?

Thanks in advance.

@madcodger,

Anything up to 32GB will work. Minimum 2GB. 

With kind regards,
Michel

Thanks, @Michel Kohanim. I’ve never had an ISY card fail, but figure it’s a decent idea to be prepared for the worst, just in case.

 

Will the ISY support a XC SD card or only the HC ?   I understand the 32GB limit and I am not interested in larger size but rather fastest possible SD.   

I looked this AM and the fastest SanDisk A2 U3 v30 cards only come in XC (extended capacity) format at 64GB.   While going to a 32GB card drops to A1.

I take it the XC format is not recognized by ISY ? 

@junkycosmos,

We have not tested XC.

With kind regards,
Michel

ISY only uses 2BG of any card. I am not sure if it fragments the card at the sector level when you format the card inside ISY.

My older 04/02/2012 ISY994iPro has a 1GB SD Card and my newer 04/13/2017 ISY994i has a 4GB SD Card.

Correct information

I suspect ISY uses the older FAT formatting and it can only handle 2GB max.

 

I have been caught many times with this gottcha'. You can format the card to 16GB or whatever, but when the actual usage of the card exceeds its addressing limit of 2GB, the system crashes after running for years without a problem.

 

2^16 = 64K x 128 byte sectors = 2GB

 

2GB cards became obsolete

 

My 8GB inserted into my ISY maxed out at 2GB reported by ISY.
