Topic: JB3 Recording failed

[Norm]

Hi,

I was taping a show last night. However my battery didnt seem to be charged properly, its probably on its way out.
I dont know how much of the show got taped (5 mins or an hour).
When you stop a recording it normally says "Processing Recording" or something similar.
I assume as the battery died it didnt do this part. As such, there is no file on the JB3 for the recording.
Is anything that was recorded now lost, or is there some way to recover any recording that was made?

Thanks

Norm

Hahaha, Same exact thing happened to me last night. 

I dont believe there is anyway to get it back, which really sucks, cause I lost mine right at the end of the 2nd set of the show with like 2 minutes left.

AFAIK, and IME, if the "processing" piece doesn't happen all is lost.  I've read that here and it's happened to me personally - jb3 "froze" for some reason (I was new to it at the time so likely user error) so I had to pop the batts out to get it to stop/restart.  There was no recoverable file that I was ever able to find...

Thanks guys.
Disappointing,but hey thats life

Did you try the jb3 recovery function?   I think it is 'clean up'.

If that doesn't work you might be able to recover it by removing the drive from the jb3, attaching it to a PC and using photorec.

I did try clean up.
Whats involved with removing the drive? Reasonably straight forward?
Attach it to the PC using a standard IDE cable?

It's a 2.5" Laptop style hard drive... not a 3.5" desktop hard drive.

pretty sure Windows wont recognize anything...other folks have been down this path...

I assume I could use some kind of adaper?

But then it seems it might be a fruitless exercise anyway?

There are cheap adapters that will let you connect the drive to the normal pc cables. In this situation direct ata is better than usb.

Photorec searches raw drive data and identifies file type based on contents/header/hints. The drive doesn't need to be mounted, just accessible. I run photorec under linux so your experience under windows may be different.

It may or may not work with the proprietary file system on the jb3... but I expect it will.  It is also possible the author would extend the software to support the jb3 if he received some help in identifying any format oddities.

I've never torn apart a jb3, so no help there. There are some howtos on nomadness.

I think it is definitely worth trying... If you can verify that it works then other folks will have an option to recover their otherwise lost shows.

Thanks, I will give it a try.
I will try and source an adapter locally tomorrow.

I tried recovering a JB3 with R-Studio which is also a lowlevel HDD recovery tool (looks at raw data only) and it only found TXT files on the JB3.  I have been able to use this tool to recover WAV files on other drives.

These tools are hit and miss and you usually have to use a few to get all of your types of files.

Let us know if you have any luck.


BTW - I used a USB 2.0 to PATA IDE 2.5"/3.5" cable for this purpose that I picked up off ebay for about $25 shipped.  They now have cables that are USB 2.0 to PATA and SATA and support 2.5" and 3.5" drives - they are also cheaper than buying a 3.5" to 2.5" adapter many times.

The one I got is at the below link on ebay (minus the SATA cable)

I am based in the UK. Would take a while to get one of those shipped from the US.
Would one of these work?

[Norm]

I think its still worth a try.
I will let you guys know what happened.

Been trying this photorec tool on a usb drive I have. It covers lots of file types, although it hasnt found any WAV files yet on a 300gb drive. If the author is willing to help, I have contacted him already about some othere issues, maybe we can get somewhere.

[it-goes-to-eleven]

I'm sure you've discovered that it is important to disable file types you aren't interested in...

Odd that it isn't finding your wavs. I've used it on a variety of media.
