UPDATING DATABASE ON JB7

[Chrissy7090]

Hi 

I have owned a JB7 since forever but it  has been in “storage” since I moved house a year or so ago. I have also used my b2 almost exclusively since then. I now want to put the JB7 in my conservatory and to that end have attempted to update the database. I have done that many times with a blank Cd using the software suggested. However my attempts to update    

To the current database are proving problematic. I have burned the Cd but when put into the JB7 it is immediately spat out without updating. 

What am I doing wrong???.

Regards

Hi Chrissy7090,

I recently purchased a secondhand JB7 from eBay, advertised as faulty.  When I received the JB7, it powered up and played music, but on trying to use the CD drive, it did as yours is doing and just spat the CD out.  I realised that the CD drive motor was not spinning up to speed (it should make a low level whirring noise that increases in level until it gets to its maximum speed).  So I bought a CD drive from eBay, swapped it into the JB7, powered the JB7 up, inserted a CD and now I could hear the CD motor spinning up to speed.   The CD functions are now working.

When you insert a music CD can you hear the CD spinning up to speed? 

Does the display show ''CD 12' or similar instead of 'CD --'?  

Can you rip a music CD to the JB7?

If the answers to the questions above are 'Yes' then the CD drive is OK, and below is the process that I ran through.

1.  Download the latest 'sqdb.zip' file from the Brennan wesite to my server (or laptop)

2.  'Unzip' the 'sqdb.zip' file to a suitable location on the PC.

3.  You will now have a file named 'sqdb' (the latest one is 588,415 KB size).

4.  Start up your CD Burner program.

5.  Insert a new CD-R.

6.  In the CD Burner program select the 'sqdb' file

7.  Select 'Finalise CD' (or it might say 'Close CD' or similar terminology)

8.  Run the CD burn.

9.   Transfer the CD to the JB7 and run 'Settings menu'  -->  'New CDDB'

10.  Takes 10 - 15 minutes for the update to load into the JB7.

If the CD drive spits out all CDs, then the drive is probably faulty and will need to be replaced.

Let us know how you get on.

Regards,

Peter.

Hi Peter 

Thanks for yr reply...my jb7 works perfectly playing music CDS. The only issue is updating the database when the machine. Spits out the Cd.I was thinking that maybe, because I haven’t used the machine for a long time, that the software may need updating but how I do that iis not clear to me.

Thanks again.

Hi Peter again.

Tries again using a different burner program x same result. 
Jb7 spits Cd out after a few seconds but plays music cds perfectly!,.so from  your detailed instructions 1

-9 works ok.. then it stalls on. no 10

Hi Peter & Chrissy,

I have had the exact same problem. Everything is working, but as soon as the CDDB should load, it ejects the disk. I believe it was before Christmas that this started. In my situation I only had a few CDs to load up, so I did them manually via usb. I just thought that as Brennan were using other databases now, that was the issue.

Hi Peter,

Which download link did you select from the web site?

Paul

Brennan Support.

[Barbs]

The Google Drive link, which I always used successfully in the past and the CDXP Burner.

Hi all

Just to add some more confusion I have just burned my 6th database disc. None of the previous 5 worked.

Did nothing different and guess what? ."It finally worked,!!!

Don’t ask me how or why!!

That's good! I've only done 4, so I'll give it another go too.

Hi Paul,

I used the Google Drive link; on the Brennan Home Page --> 'News 2021' --> 'New album database' --> 'more' --> 'New album database for JB7 and B2' --> 'JB7' --> 'Download this file'

The 'sqdb.zip' file is 362,944,379 bytes in size and then decompresses into a file named 'sqdb' which is sized at 588,415 KBytes.

Once burned onto a CD-R disc, the 'Update CDDB' ran for 10 - 15 minutes and loaded up into the JB7 without any problems.

I read on another forum that the JB7 doesn't like CD-RW discs but I am going to test that as soon as the JB7 'Backup finishes later today.

Regards,

Peter.

Hi Crissy,  Barb and Paul,

Further to my post above, I did read on this other forum that the JB7 CD drive can be fussy about the brand of CDs that are used.  I was inclined to dimiss this but perhaps there is something to consider.  You can find the forum discussion if you Google 'JB7 database problem'.  There is a JB7 user called 'DougCuk' who offers good advice. 

The other thought that I have just had is that for CD burning, I always use a full size CD unit, because it burns very reliably due to its larger physical size (the bigger the CD motor, the more stable the motor speed is which gives a higher quality burn).   I have had problems in the past with CD burning on PCs and small portable drives so I don't use these 'compact drives' for burning.  They are fine for CD reading.

Regards,

Peter.

Also, you will get a more reliable CD-R if you burn at a slower speed.  I burn at 8x.  The faster the speed, the more likely there will be problems.

[Peter Lowham]

Daniel,

That is a very good point to make.  I'm going to do some tests on CD burning, so I'll keep this in mind.

Regards,

Peter.

Hi Peter,

If I have it right, I think that under normal circumstances the slightly shakey data burned at a fast speed will not be any different than that by a slow speed.  I think where it begins to be noticed is when the fast disk errors are in an opposite direction from how a CD drive may vary from spec.  It's more likely to make a difference on a music CD than a data CD (even if the data is music).  This is where my knowledge gets foggy.

Hi Peter,

After Chrissy's success, I gave my database yet another go and it worked too! Up to date for Feb '21.

Hi Barb,

That's great news and thanks for the update.

Regards,

Peter.
