Hi Kalide,
Are there any pins on the drive or interface to prevent the drive going into sleep mode ?
Are there any pins to make sure the SATA interfaces works at 1.5GB intead of 3.0GB/s (i.e slowing it down a little)?
There are 4 pins, but bought it OEM so at first it went with no docs. I finally found the documentation on Samsung's site :
http://aerodrink.free.fr/temp/MH320JI.pdfThey say :
SATA 1.5Gb/s Speed Limit Jumper setting Only for
SATA 3.0Gb/s products. In some rare cases SATA 1.5Gb/s
hosts can not establish SATA interface connection with
SATA 3.0Gb/s devices due to interface protocol issues.
In this case the jumper may be installed as shown on the
figure below to force the device to negotiate for SATA
1.5Gb/s speed.
So first, as my drive is 1.5 Gb there is no jumper to put on. Then, if I look at the PDF (2 pages only) I don't see the jumpers on their scheme ... only the empty pins
I should give it a try anyway, but the size of the jumpers is smaller than the ones used on conventionnal 3.5" size and I don't have such small jumpers at the moment
By the way my SATA->IDE adaptor is SATA 1.5 Gb compliant so theorically there should be no pb ...
Do you need additional external power for the hard drive rather than powering it from the SATA connector ?
I tried powering it from my desktop's USB bus while it was connected SATA->IDE to the sampler, with no success. e6400 still sees the drive, but always in sleep mode.
Also - do you know if the interface works on a regular PC already before trying it in the Emu ?
You're right ! I'll try this tonight when I'll be back from work. I already connected the HD with USB on my computer and it's well recognized (tried to format it FAT32, then tried with no partitions, etc. never succeed to work on the E-MU). But you're right : I have to know if the problem comes from the SATA->IDE adaptor or the HD itself.
Thanks a lot for your usefull suggestions !!
