Odd ResScan problem

[DocWeezy]

Has anyone experienced this?

ResScan has decided not to be able to read last night's data...there is data on the card for 5-10-11, and the files are a different size from the files for 5-9-11. But when I go to upload them, ResScan simply doesn't see them and does not import any of the files dated 5-10-11.

I'm going to upgrade by ReScan to 3.14 (currently running 3.12), but having had time to find out where the actual data files are stored on my machine so I can back them up before removing the current version. If anyone knows that off the top of their head, I'd appreciate it!

Any ideas on why the sudden refusal to recognize last night's files?

Thanks!

Any change you went to bed before midnight one night and after midnight the other night?

Or ...

Are you getting just a blank outline for the one night w/no data? Were you given the option of Overwriting that date? If so, select Overwrite rather than Discard. If it doesn't work, you just don't Save it.

I've downloaded after noon and gotten the data from the second night before but not that night's data. I just make sure that the next time I download I do so before noon and when given the Overwrite option I do so and voila! the data appears!

That is assuming, of course, that one hasn't waited more days than the card and PAP are capable of reporting the Detailed data.

Thanks for the ideas, Slinky, but no to all of the questions. I download every day (did I say I was obsessive?)...no blank anything, the card was erased about two weeks ago so it isn't full, ResScan just simply pretends nothing is there but I can see the files on the card. Odd. Haven't had any time to play with it today.

Any other ideas?

If by some strange reason, and I don't know what it would be, the CRC file was corrupted, or calculated incorrectly, Resscan will not read the data file. Or, if for some reason the data file got changed and the crc file did not, it won't read the file. Did you by chance remove the card from the machine within seconds of turning it off? If so, that may have done it. I don't know how quickly the S9 completes all its writes after the machine is turned off (blower off), but it is not instantaneous.

Sounds like it only happened once to you. Now you have one more day to try and read into ResScan.
I've been also faithfully storing the results into the ResScan database. Lost a day of detailed data once after changing clinical parameters, another time after I waited too many days to download.
I wonder what happens when a ResScan resource limit is reached on one's particular computer.
A sanity check: the ratio (BRP file size) / (recording time) comes out to be around 350 KB / hr

Unless you have an exceptionally low capacity hard drive in your particular computer, you will have shuffled off this mortal coil before that is likely to happen.

Bill, that's just one obvious resource to worry about. I haven't tested the program's robustness, but I seem to be getting close to a bottleneck.
I am running ResScan v.3.10 on the only PC I have with a compatible OS: WinXP-SP3 on an old Pentium 3, 1 GHz, 512 MB RAM.
I have accumulated ~400 hrs of CPAP detailed data, and with each download the sw appears to take longer to get to the point where it displays all the recorded nights in the Patient file, meaning that it is ready to provide Summaries & Statistics. When I pick a night for detailed data curves, or a date range for Report, the CPU and memory utilization shoot up to max.

DocWeezy, you could take a look at your directory C:\Program Files\ResMed\ResScan3\Patients\YourPatientName and check the date+time of the most recent RLK and Summary.dat files. For all we know, maybe ResScan takes forever to update its database. In which case, since I have all raw data downloads and the latest patient database archived, I could reduce the running database to just the last month. And do separate incremental archives for the total picture.

I notice that the specs for v.3.14 require a more powerful computer. And it still won't run under WIn7 Home. Looks like ResMed needs to upgrade their in-house platforms.

When you uninstall ResScan, the data previously downloaded remain on your computer and are recognized when you install a more recent version. You do not need to backup the data before uninstalling one version and installing a more recent version. I have done this multiple times and never lost any data.

You have an old PC, running an n-2 operating system version, with not much memory and a very slow processor. Your particular performance results are entirely predictable, however, even that poor environment will not stop ResScan running.... it is just going to take a while in such highly resource constrained circumstances

Just FYI, I have had no trouble running ResScan 3.12 on a Windows 7 Professional 64-bit machine - the smart card reader was supported natively (only had to run a Windows Update) and the ResScan program installed with no changes or tweaks (just skip any driver installations). The only problem I had was moving the patient data from the other computer. Exporting and importing did not work at all; I had to copy the patient folder, instead, but that was straightforward.
