Third Party > Repairing and Upgrading Rockbox Capable Players

Got JBfmR V2 to power up....still got register error.

(1/1)

infoguy:
I had my JBR sitting around gathering dust for quite a while until I upgraded a friends 2.5 HDD in his laptop for him and he gave me the Hitachi Travelstar 60gb he wasn't using.

At first i couldn't get the damn thing to even charge until i held down the on button for the Archos and seen green flashing from the led at the top. When I seen that, I left the unit plugged in for about 15 minutes. When I unplugged it, I jiggled the cover, plugged it back, and both LED's came on. The "charging..." screen came up. I did the happy dance.

I let it charge overnight to a full charge. I woke this morning to turn it on and I received:

HD Register Error

SC1 (85) 227
SN1 (170) 0
SC2 (170) 18
SN2 (85) 211

Searching the site I found various fixes and tired most. I've looked at all my solder joints around the connectors for the HDD and everything looks solid. I don't think It could be a battery problem since the battery apparently took all night to recharge. Also, I made sure my regular jumper settings were set to Master (no jumper).

The only other fix that I seen could be is to jumper of pins 28 and 30 fix i have read about in http://forums.rockbox.org/index.php?topic=20.0 thread. I'm not sure If this also applies to Hitachi Drives too. The amps compared to my old drive are double. The new drive is 1.0a. The old one is 0.5a. I realize the setting jumpers on 28 and 30 can short your HDD but I'm willing to chance it if the fix is suggested. If jumper fix is the way for me to go, would someone tell me which pins are 28 and 30 from the picture from Hitachi's PDF documentation?


I'll take any other suggetions on a fix too. I want my ole buddy back up and running :)

---EDITED---

OK. I realized that the pins were already numbered for me in the documentation above. The 1,2,3,4. duh. I have marked 28 and 30 in the photo below:


Before I try this fix I would like to get a suggestion or two from more seasoned forum members though. Make sure I hve the right pins marked and make sure I have tried all other options before this fix.

Last night I stayed up till 4 am testing.

Through this I found out that it MUST be a solder joint that has come loose somewhere. Be it ground or battery.

I came to this conclusion based on 2 things. I took my 40gb Toshiba from my laptop, cloned the drive to my spare 250gb, and then cloned that information to the Hitachi 60gb I was trying to use for the jukebox in my first post. I formatted the 40gb to FAT32 (primary), stuck it into the Jukebox. I still got the same registry error message. The only thing that was different in the registry error were the numbers outside the (), which were all number 1.

After that I decided to do something I probally should have done in the first place. I hooked up my original, thought to be broken, HDD from my Archos, into the portable 2.5 HDD case. It spun up. I even copied a bunch of files to my PC, from the HDD, everything is fine with the drive.

So it MUST be a ground connection or a battery connection problem since all HDD, including my original, seem to work from the portable 2.5 case.

I have looked at some of the Tutorials for battery connections and grounding but i can only find the tutorials for the v1. I need tutorials or help with a v2. the one WITH the long, flat, rechargable battery.

Can anyone link me to some tutorials or give me some hints based on the new information I have come across overnight?  

LinusN:
This page has some interesting info about fixing battery issues among others.

It is also linked to from the rockbox.org documentation index page.

I think the pins you have shown are wrong it would appear that all odd numbers are on the top row and even numbers on the bottom.
I think 28 & 30 must be on the bottom row.
