Hi, guys ! :)
Please, continue to give your oscillator value,
to add to this
post,
I erase mine, so I test many of them.
Many managed to load backups, in fact lot of them,
but with some I have to insert the disc several times to be read correctly, or unplug the pic an replug it.
So I keep testing, and I have better results with one of them.
Backups are recognize immediately (maybe it the value of my pic). :p
34AC -> OK,very well, discs recognize immediately *****
344C -> Ok, but disc recognition problem**
3448 -> Ok, but disc recognition problem**
3490 -> Ok, but average disc recognition **
3448 -> Ok, but disc recognition problem*
3450 -> Ok, but disc recognition problem (unplug needed)*
343C -> Ok, but disc recognition problem (unplug needed)*
3454 -> Ok, but disc recognition problem (unplug needed)*
3470 -> Ok, but disc recognition problem (unplug needed)*
345C -> Ok, but disc recognition problem (unplug needed)*
So keep posting your manufacturer oscillator value, it can help many people who have made the same mistake as I did.
