Tyros 4 recording on hard drive -disk is busy error

<< < (2/4) > >>

EileenL:
If you get the message media error then it does sound like the hard drive. The original ones fitted were 250Gb. Two or three people I know have had there hard drives replaced Also of course it can be the holder it goes into Make sure the USB is fitted tightly.

Will do. Thank You!

Hi Joe,

The internal hard disk on a Tyros4 connects to the keyboard via a SATA to USB interface card which is fixed to the actual disk case with small bolts.  You presumably are aware of this if you have changed the drive!

The interface board has a mini USB socket which connects to a cable from the main circuit board.  The plugs on this cable have been known to come loose at one end or the other.  I think that this is what EileenL is referring to, and is certainly worth checking.

The reason that I asked if the disk was working for other files was to see if it is working at all.  If you open a file selection screen, the style screen for example, is the disk listed in the tabs at the top of the screen (as HD1)?

If it isn't, and you are sure that the hard disk cable is correctly connected at each end inside the keyboard, then there is probably a fault.

This could be with the hard disk, but if you have tried a new disk this is unlikely.  (I assume that you transferred the interface card from the old disk to the new one!)

It could be with the SATA/USB interface card itself.  This failed on my own T4, although I was able to ascertain that the the disk itself was working fine.

You can check the disk and the interface card by removing the disk in it's caddy, then connecting it to your computer using a suitable USB lead with the correct mini plug on one end.  The disk should appear as a drive in Windows Explorer if you expand 'Computer'.  If it doesn't then the fault is most likely to be with the interface card since the disk is new.

Yamaha UK would only sell me a new hard disk complete with the interface, and they wanted a stupid amount of money for it (£242 GBP! and that didn't include fitting which is a simple job that should take only a few minutes!   Note that the same model of Seagate 250 GB hard disk cost around £40 brand new at that time, so they were trying to charge £200 for the interface card!!!  :o >:() 

Knowing that my disk itself was fine and declining Yamaha's kind offer, I purchased an enclosure for a USB 2.0  external 2.5 inch SATA laptop hard drive which of course contains an interface. I deliberately looked for one with the same mini USB socket as the original interface card so that I could connect the cable without needing to use an adapter.  This cost around £6 GBP from Amazon, and I plugged the original T4 hard disk into the interface from the enclosure and connected it to the T4.  It has worked fine for a year now.  In fact I have recently tried the disk in a USB 3.0 version of the same enclosure because the USB 2 ones are becoming harder to find and I wanted a spare interface, and this also works fine in the T4.

I have also tried this with a SSD which also works fine in the T4, but obviously because it is connecting to the painfully slow Yamaha USB 2.0 bus, there is no significant speed advantage in the keyboard, but it is very much faster when I connect the drive to a USB 3 port on my computer to back up the Tyros disk.

So if you haven't already got one, you could get a similar enclosure to enable you to check if it is the original Yamaha interface card that is faulty. If it turns out to the problem is with the interface, you could simply use the one from the enclosure, unless you are happy to swell Yamaha's profits!  I actually discarded the outer case of my enclosure and just used the interface from it, which allowed the disk to fit securely back in the caddy, which if you are transporting the keyboard regularly is probably a good idea.

Even if the problem is not with the disk or the interface card, you will only have spent a small sum, and you have an empty portable hard disk enclosure which you can use with a hard drive if you have one lying around (maybe the original from the T4).

Of course if this indicates that both the disk and the Yamaha interface are OK, it probably means that the problem is on the main Tyros4 circuit board, and you will probably have to have a new board fitted, since most service technicians these days won't (can't !  :o) troubleshoot circuit boards, they simply change them!

If you do think the problem is with the main board, it would be worth contacting Yamaha to see if they are prepared to help.

Ian, Thank You!
I will try your suggestions this week. I have already tried two hard disks which I bought. I transferred the interface and connected to the computer and formatted it. Then I formatted it again on the key board. I was able to connect one HD to the computer but the other did not work. However, when I format it on the keyboard, it does not format (comes up as Media error). Being not a computer guy, it is really hard for me to diagnose the defect. is there an alternative way to bypass the hard drive and record on a USB? When I create a multi track file it seems to create it on the HD and not on the USB even if it is connected.

I will also take it to the local Yamaha tech people this week as a last resort

Again I very much appreciate your willingness to help.
Thank You!!!

The Tyros4 and other Tyros models can only record audio to the internal hard disk.  You can't record to USB I'm afraid.

If you were able to connect and format a hard disk to your computer using the Yamaha SATA/USB interface card, this presumably means that the interface (and disk drive) is working correctly.

However if you use Windows 7 to format the drive, it is likely to default to formatting it as NTFS  unless you specifically tell it to format as FAT32 which is what the Tyros4 requires.

When you format a drive using the Tyros4, it will format it as FAT32 and create the 'AUDIOREC.ROOT' folder which is used for Multi Track audio recording.

I don't know what happens if you try to record a multi track audio without this folder being present.  It is possible that the keyboard OS may simply create the folder the first time that you try a Multi Track recording if it is not already there!

You said "I have already tried two hard disks which I bought.  I transferred the interface and connected to the computer and formatted it. Then I formatted it again on the key board. I was able to connect one HD to the computer but the other did not work. However, when I format it on the keyboard, it does not format (comes up as Media error)."

This is a bit confusing, but it sounds as if you have one hard disk that you can connect to the computer, and have also been able to format using the Tyros4.  Is this the case?  Have you been able to format one of the new hard disks using the Tyros4?

When I had the problem with my own Tyros4 hard disk, out of interest I tried connecting a USB memory stick to the T4's internal  hard disk cable (using a suitable plug/socket adapter).  The device connected to the keyboard and appeared as another USB rather than as HD1 as I was expecting, so presumably the keyboard can interrogate and identify the type of device connected.  I didn't try to record audio to it but I suspect that it would not have worked!  However this at least confirmed that the T4 internal USB cable was connected to the T4 main board.

So you could try to do the same if you are not sure that the USB cable on your T4 is correctly connected to the main board.  If you do this and the device does not appear in the drive options, then this suggests either that the cable is not connected at the main board end, or that there is a fault with the cable itself or the USB interface on the main board.  However if you were really able to format one of the new hard drives in the Tyros4, then neither of these possibilities would appear to be the problem!

Please confirm if you can save and load files such as styles or voices to the hard disk that is currently installed in your T4.

Ian
