Creative 8gb mirophoto freezes at logo
I suppose that you have a bad hardisk. I have repaired several models of Creative Zen including the hardisk types (Zen Micro, Microphoto, Neeon, Zen 20 Gbytes, and your problems points to a bad hardisk symptoms. Either the disk or the read/ write head stuck up. Do you hear clicks in the player upon startup? If yes, then do the following procedures:
If you're out of warranty, then you might want to open your player, and do some repair yourself, but be very careful. Somebody has posted on how to dismantle the zen microphoto, please search for the site.
Once you got to the hardisk, carefully remove it from the player...
Remove the sticker. There's some holes in the cover, can you see the disk and the read/ write shaft? Insert a piece of wire or anything that can be used to move the shaft a little, again be very careful. AVOID SCRATCHING THE DISK OR, Move it to the right. If you're lucky to have just a jammed or stucked shaft, then you just save bucks. Replace everything and test your player.
You might want to modify your player by replacing the hardisk into a compatible compact flash. it is the same size and same pinouts. A step-by-step procedure has been posted somewhere, please search for that.
If you're player powers up and freezes on creative logo, or go to the recovery mode directly, then your player still works, and you just got a hardisk problem. try replacing it.
I'm lucky enough to have a warehouse in my area here in the Philippines who sells surplus Creative mp3 players (various models and products)for a very cheap price, sold asis. So I have ample stocks of boards and parts for my repairs.
