SH205 and SatanDisk

[jvas]

Hi Uwe,

I'm using HDDriver 9.04. There is an SH205 and a SatanDisk attached to my Mega2. The SH205 has a 40MB drive with one partition. The Satandisk has a 128MB drive and four partitions. During boot, HDDriver recognizes both de devices and partitions correctly. But in HDDRUTIL in the devices window I see only the SH205 and in the partitions windows all 5 partitions seems to belong to SH205. I pressed the refresh buttons many times on both windows.
If I press the "device check", then it displays both devices correctly. Made some screenshots: https://www.dropbox.com/sh/g67xnw0mwlr3 ... BArba?dl=0
Do you have any clue what I'm doing wrong?

Thanks for your support in advance!

Cheers,
Jozsi

Hi,

When checking for a device (name, type, capabilities) HDDRUTIL has to use more SCSI commands than HDDRIVER, because HDDRUTIL needs more information about the device than HDDRIVER needs when booting. If a device does not react correctly to unknown SCSI commands it is considered not to be a SCSI device but an old Atari SH/Megafile drive. Looks as if SatanDisk does not report proper error codes and is classified as not being SCSI.
Note that HDDRIVER does not officially support SatanDisk, whereas UltraSatan is supported.

Take care

Uwe

Hi,

Thanks for the quick reply. Now I see, that SatanDisk is not supported.
Still not understand, why it appears correctly in HDDRUTIL's check devices window and not in the "devices" window...
Thanks anyway.

Though, this site http://joo.kie.sk/?page_id=55 states it is HDDRIVER compatible, but of course should know better

Hi,

The device check uses a different sequence of SCSI commands than those used for displaying devices in the device window. Note that the device check does not even require that SCSI Driver support is available.

As far as compatibility is concerned claiming compatibility to HDDRIVER is quite useless. A device has to be compatible with the SCSI standard and if it is it will also work with HDDRIVER and other drivers. Even the UltraSatan had problems with SCSI standard compatibility, and more than a year ago several firmware updates were published for the UltraSatan. The SatanDisk is much older and I don't think there were any recent updates, so it's not surprising if not everything works as it should.

The SDRVTEST tool, which can be downloaded on the HDDRIVER website, runs some tests that have to do with SCSI compatibility. Most likely SatanDisk will not pass some of them.

Take care

Uwe

I can run the test and post the results here, if you are interested...

Well, regardless of how the results look like, if errors are reported I don't expect that they will ever be fixed.
