Total waste of time.
As stated above. 1.24 is a VERY minor (and RARE) bug fix. And 1.25 - 1.28 are only aimed at the new drives with the faster NAND.
To be totally honest... I would NEVER upgrade the firmware in any device unless there was a bug fix for something that was personally giving me a problem, or it gave me some tangible improvement (EG. in the case of SSD's... improvement in TRIM processing, or speed improvement/s etc.). If only because there is "always" the chance that you could brick your device!!!
had a feeling that may be the case, thanks mate
