Disklavier

\ufffd

Gentlemen,

This is an interesting thread to read. \ufffdI have what may be a obvious (or stupid) question. \ufffdInstead of replacing the HD, why not use a USB flash drive? It seems the biggest concern is loosing the music files following a crash - the USB drives can be easily backed up. And they are inexpensive! For example, you can buy a 64GB drive for about 40 bucks, which is cheaper then retrofitting the control unit. \ufffdI know the DKC 850 has several USB ports, however don\ufffdt know about other control units (I started with the DCS2 w/ DKC500R)

I look forward to being enlightened :-)

Regards,

Rich Freeman

externalizing the drive sound like a great idea. if it is SATA, that should be real easy since the cables are more flexible. with ATA it might require some ingenuity. you can can get a ribbon cable to make twists and bends by separating the individual wires into clumps of 10 or so. if the cable is really long, the alternating ground wires are important so it is best to do the separating just for the sections that need to be twisted or fitted through tight areas. you can also find aerodynamic cables that have been made round. they generally have twisted pairs which are actually better than just parallel wires. i have a large spool of this twisted pair wire but never needed to use it yet.

Right.

DKVBrowser can only do what yamaha intended the PRC-100/TRC-100 to do.

I did built a "backup" option that will move all non-protected files to your PC along with a meta-data file so you don't lose any of the meta information (comments, song title, ratings, last played date, etc.) when you choose to move the files back to the piano. \ufffdThis is incredibly important if you ever have to replace the disklavier itself, since a Yamaha backup is "locked" to a particular piano.

But, it can't do protected files, and it can't do anything about the operating system.

I wonder how difficult it would be to rig it so that the SSD is EXTERNAL to the Disklavier. \ufffdThen a quick disconnect/backup (image)/re-connect operation could be done via some other computer.

It occurred to me after I wrote my message that, as Kevin will verify, there\ufffds no way to do what I\ufffdd like. You can\ufffdt mount the file system and then do a disk image of the whole thing\ufffd i.e., you can boot the HD or SSD\ufffd i.e., this could only be made to work if you boot the piano off a CD or USB stick and then do a disk image.\ufffd

As per below, it\ufffds possible to boot off a CD. That means, if someone ever felt like getting around to it, you could create a CD that boots a minimal OS and then captures a disk image of the SSD and dumps it to a USB stick.\ufffd

Bill, thank you for offering\ufffd I don\ufffdt think I\ufffdll need the 3-CD set because I have a relatively recent image of the SSD I installed. Whether the restore function works off a backup\ufffd who knows, I hope I\ufffdll never need it. At some point I\ufffdll remove the SSD and clone it and perhaps every 6 months swap one for the other, always having a pretty current one and a backup. It\ufffds not trivial removing that drive but it\ufffds not a huge deal either.

That does sound easier if you make the clone before the HDD dies.

sounds like a lot to do compared to a simple disc cloning that takes about 30 minutes of unattended waiting for a 1 tb computer drive that has about 250 gigs of data on it.

NEAL and HORATIO,

I have never experienced the backup/restore problems that Neal has described. I have never found the Mark IV backup/restore function not to work. I backed up last week. After seeing your emails, I decided to do a restore and it looks like it is working perfectly. (I won't know, however, until the process completes in about 3 hours.)

During the last year, I have replaced my hard drive twice. The first time was with a standard hard drive I purchased from an electronics store. The second time I replaced the drive with a SSD drive. In both cases, I did backups before the replacement and then used the restore function to get all of my music to the new drive. To say the least, I have a considerable amount of software (one of the benefits working for Yamaha for 31 years...). As a result, I actually have two different backups (with two different sets of music) \ufffdI work from. By using the restore function, I am easily able to switch back and forth between my two sets of music data.

NEAL, my Mark IV operating system is currently DIO 4.21. The two USB hard drives I use have been formatted as MS-DOS FAT 32. The only negative I can find with the Mark IV backup/restore function is that it takes a long time (USB 1.0). So, before I go to bed, I start either the backup or the restore. When I wake up, the job is done. Neal, give it a try. Just make sure that your external drive is formatted MS-DOS FAT 32.

HORATIO, first of all, there is an easy way to take a hard drive and use it with the Mark IV. First, do your music software backup. There are RESCUE CDs that can be used to place the operating system, internal piano voice and all of the factory installed music software on the drive. Three CDs are required, along with an update floppy. To do the rescue, the 1st CD is inserted in the drive, along with the update floppy. The piano is powered on and a couple of buttons have to be pushed on the I/O center during the boot sequence. When the 1st CD has been loaded, the CD drive ejects the CD and then you insert the 2nd CD, after it is loaded, you insert the 3rd CD. After the 3rd CD has been loaded, the rescue is done. The piano is now running operating system DIO 3.0. From there, you can perform your music software restore function, and then update your piano over the Internet using Network Update.

If you need the three iso files that make up the 3.0 rescue set, let me know and I will send you links so you can download them. Each of them are about 600 MB and each are burned as an image to the CDs. I can help you with this process, if you need assistance.

Bill
