Hello,

I need your help on a well-known issue.

One of our concert has been recorded and transfer to a pc then Md has been formated.

All I have now is a directory with .hma files, how can I get them convert to .wav.

Thanks for your a help,

Anthony

Hi,

did you try it the other way around already? Copying the *.hma files from the pc back to an empty HI-MD disc and then importing them with SonicStage and convert them to wav? Maybe that works.

I don't think you can process the *.hma files on the computer directly.

EDIT:

Ok, I had a quick look around an it doesn't seem to be as simple as I thought it would. You can only recover data from a HI-MD disc if you used an rh-1 as a recorder and you will also use an rh-1 for the recovery. As I don't have too much time on my hands I will only provide you with a link to the 'HI-MD Recovery'-post on minidisc.de. Babelfish should do the job, otherwise just ask what's unclear.

That same page translated by babelfish. U'll have to use some imagination, though.

Oh, well ...

I didn't use Babelfish for ages and thought it would have been improved by now but that doesn't seem to be the case.

Hasn't this artice been translated already to English somewhere? I could do a translation but actually I should be doing other things instead of that.

Here is a translation of the article which was posted on the mindidiscforum.de (link: http://www.minidiscforum.de/forum/viewtopic.php?t=15456) by enaef. All credits go to him. I only did a quick and dirty translation.

PS: Sorry about the sloppy formatting. I'm going to change that probably soon. Improvements and corrections are welcome, of course.

Start of Translation:

Starting point:

Sony MZ-RH1 and SonicStage 3.4

No recordings assembled in groups (just recorded as one long stream, no parts cut out or moved)

The recordings can only be recovered with the help of some manipulations. It doesn't work with the RH10. Furthermore it only works with discs which have been formatted in the RH1 prior to recording. When recording was done with an RH1 and an RH10 on the same discs only recordings done with the RH1 can be recovered.

It doesn't seem to matter if the disc is formatted via SS or by selecting to format it on the unit.

How to proceed (actually rather simple)

Access the faulty disc with the help of MS file explorer. Copy the container file 'ATDATAxx.HMA' to your harddisk (the two xx are substitutes for changing characters, usually the first one is a zero, the second one either a number or a letter. Those characters change every time the recorder writes to the disc).

Now take a fresh disc (type doesn't matter, can be a standard MD or a HI-MD) and format it. The faulty disc could be used for this task too if you still trust that thing.

Disconnect the RH1 from the computer.

Start a 'pseudo'-recording, which has to be a tad shorter than the one on the faulty MD. Attention: this 'pseudo'-recording shouldn't be longer than the whole recording on the buggy MD.

After the 'pseudo'-recording let SS write the system-files.

Delete with the help of MS file explorer the 'pseudo'-recording on the MD (usually named ATDATA02.HMA, if you recorded to one single file) but make sure you note the name of that recording. Now replace the deleted file (the 'pseudo'-recording) with the one you saved at the very beginning from the bad disc. Rename the file with the name of the 'pseudo'-recording.

Disconnect the RH1 from the computer. Choose 'line out' on the RH1. Now you can copy the recording to another device. When the recorder hits a track mark which was set on the faulty disc there is a short break. (If the RH1 isn't set to 'line out', it looks as if it is playing (at least the meter seems to indicate this) but there is no sound output till you move the jog lever to ff).

Instead of playing the recordings on the RH1 they can also be played with the help of SS:

Connect RH1 with the computer, start SS. Now you should be able to see the 'pseudo'-recording in the view 'transfer files'. When you play that recording now, the recovered recording should be played. It will play properly till the point where the first track mark was set is hit on the faulty disc. Then SS will stop and jump back to the start of the recording. The track bar has to be moved over that track mark in order to make SS/RH play on.

The file can be imported from the MD to SS without any problems. If you play the files they behave the same way like when playing them from the RH1 though.

Converting to WAV works till the first track mark is encountered and then the converting process will stop. Trying to convert the recordings to another bit rate will result in an error.

Wow! This is exciting info!

Looks like Sony has slackened cryptographic madness in RH1 quite substantially, so this unit should be considered much safer for serious work.

dear roem,

I have almost the same problem. Our team transfered some recordings to the Hard Disk via USB before we set up the SS on the computer. Now we can not open the .hma file which was our two years reading research result.

I have tried the method you mentioned to save my data. However, some problems occurred.

Does the method you mentioned work on SONY MZ-NH700 too ? How about the recordings length ?Our research recordings was about 1 hr. per disc (~800mb)

When I replaced the ATDATA03.XX on the 'pseudo'-recording processing to the one to recovered, however, the the length of the " to be recovered recording" was the same as the 'pseudo' one (which I though should be longer), and which can't be played neither on the Hi-MD nor on the SS. It Also doesn't work after they were conversed . Though I can see the to be transfered folder via the SS.

When you play that recording now, the recovered recording should be played. It will play properly till the point where the first track mark was set is hit on the faulty disc. Then SS will stop and jump back to the start of the recording. The track bar has to be moved over that track mark in order to make SS/RH play on.

Would you please explain more of this section? when we connect the MD and PC, there are two side to be played, one is the MD, the other is the PC storage, do you mean the MD side? Actually there is no response when we played the MD side , and the length of the recordings are always the pseduo one not the recovery one, also there is no normal sound showed.

Thank you so much!
