Proceeding on ejected ssd at DVinfo.net

Ron Aerts · January 21st, 2014, 03:21 PM

I understand that it is not wise to proceed recording on a ssd once ejected from the 7q. But sometimes I want to leave the files on the ssd after I backed them up. Or offload them during a pause for spotting purposes, or just want to save time in advance.
Am I always forced to copy the data and format the disk before the next shoot of the same project? When using compressed codec one can hold a lot of minutes and the org ssd can function as backup.
The 7q states that I have to do all my recordings before removal. This is a rather inconveniant workflow. It again forces me to stay up longer than the rest of the filmcrew as I have to run the double backup.

As there is still no answer, asking one more time for attention in this matter

Dave Sperling · February 2nd, 2014, 10:47 AM

Ron,

This is not a real answer since I don't have a 7Q yet.

But if it works in a similar manner to the C-D Nanoflash, then my guess is that it could work fine to eject/transfer/re-insert if transferring on a Windows or Unix system, but not on a Mac OS system because the Mac OS likes to write a bunch of extra files on the drive when inserted - which mess up the recorder's ability to continue writing on the drive until it's re-formatted.

Maybe someone with a 7Q could test with the various OS's?

Ron Aerts · February 3rd, 2014, 01:54 PM

I use both nanoflash and odyssey. MFcard stays useable as long as you dont use apple or the soft-eject on a pc. First test with the ssd was
Switch 7q off, remove ssd, upload to pc and (no soft ejected) removal of the ssd from (hot swappable) cradle. Putted back ssd in 7q and then switched on.
This worked, however it doesnt feel right though
Maybe some feedback from CD

Dear Ron,

I have been traveling extensively.

I am sorry for the delay in answering.

When the SSD is placed in a computer, many computers, Mac's and PC's will write to the SSD.

In some cases this is not harmful. In other cases it can be.

We may be being very cautious, or we may be being too cautious, in asking you not to record additional files once the SSD has been in a computer.

Here is an example of a problem that I know of:

A person inserted the SSD into a computer, then without copying the files to the computer, used Resolve to work with the files. Resolve wrote to our SSD's causing a problem.

But, we attempted to duplicated this problem in our lab and we could not get it to fail.

Thus, we are being very cautious at this time.

I hope other members of our support team will be able to add to my answer.

Respectfully,

Hi Dan,

I might be stating the obvious, but just to confirm, after recording to SSDs and connecting it to the computer, copying the files over, all we have to do is reformat the SSDs again inside Odyssey to get going again, to have no problems.

The advice is to not connect the SSDs to a computer if we have more recordings to do on the same SSDs without reformatting/deleting anything.

Also currently it is not advisable to record different frame rates (say 23.98p and 60p) on the same SSD, right? If thats the case, can one specify to Odyssey which SSD out of the two it should use for recording? This way we can use one SSD for 23.98p and the other for 60p, for instance.

Thanks.

Yes, that is correct.

Recording 60p in many modes requires two SSD's.

We do not have the ability to specify which SSD to record to, at this time.

Amir Qureshi · February 9th, 2014, 08:26 PM

Thanks Dan,

Does recording 1080p 60 to DPX sequences require the use of two SSDs?

Also, can one record multiple frame rates to the same SSD (say if the footage was 1080p 24 and 1080p 60 going to DPX sequences)?

Thanks.

Dan Keaton · February 10th, 2014, 08:42 AM

Dear Amir,

Yes, recording 1080p60 requires two SSD's.

With our initial firmware release, 1.0.214, the following applies.

After we release our next firmware, expected near the end of this month, these restrictions will no longer apply.

1. When first starting to record in any mode that needs two SSD's, start with two freshly formatted SSD's.

2. Record as many clips as you wish.

3. Then you can record in any mode that uses just one SSD.

4. But, you must upload your SSD's and then reformat the SSD's again before using any mode that uses two SSD's again.

If you attempt this, you will receive a "Mismatched SSD" message.

We have improved our firmware so that this restriction will no longer apply, with our next firmware release.

Respectfully,

Amir Qureshi · February 11th, 2014, 03:16 AM

Thanks Dan, much appreciated.

Dan Keaton · February 13th, 2014, 06:13 AM

Dear Amir,

I may have given the wrong answer. I have new information from our team.

Recording 1080p60 will only require one SSD.

I think Dave brings up a good point as the experience with P2 was similar between Macs and Windows. Always a good idea to switch the record lockout button on a P2 card to prevent a Mac from potentially damaging files when mounting. Can/Do you have a record lockout with an SSD?

Dan Keaton · February 14th, 2014, 09:06 AM

Dear Daniel,

SSD's do not have a write lockout.

But we have taken special steps to ensure that the operating system does not corrupt our files.

Only a small part of the SSD, a portion that we reserve just for this purpose, is accessible to the computer's Operating System.

However, we still error on the side of caution.

We recommend that one upload the footage to a computer as the first step.

And then perform any other necessary tasks, using the data on the computer's disk subsystem.

And then reformatting the SSD's in the Odyssey7Q.

I hope this helps.

Hey Dan,
Definitely helps give one confidence. Not sure other manufacturers are as on the ball as you guys.

Dear Daniel,

Thank you for the compliment!
