Re: [disklavier] SSD failures

2014-01-30 by Spencer Chase

i have a decent backup and restore program that actually works. i have used it to restore which is the real test. most programs do the backup just fine but when you try to restore, they fail. the program is called EaseUS Todo. i have some adapters that allow you to connect any hard drive, IDE SATA etc to the USB port. the program will backup from and restore to the USB port. it will do all the normal formats and will do a sector by sector backup for unrecognized partitions or file system formats. for example, it backs up the hidden restore partitions that are on various computers instead of an install disc.\ufffd i do not know that it will specifically back up the DKV drive but think it should. would be interesting to know if anyone has tried this.

how difficult is it to take the drive out? i doubt it can be backed up without removing it. to backup unknown partitions requires the drive clone feature. i have done this many times and the cloned drive is indistinguishable from the original. the only thing is that some programs use hard drive id numbers to determine if you are installing to another computer and this might need reregistration. i hope DKV doesn't do that.

The backup function seems to create a very proprietary set of files which I\ufffdm guessing work well within the confines of the \ufffdbackup\ufffd and \ufffdrestore\ufffd functions of the Mark IV. But if you lose the whole HD, you lose the file systems and the operating systems\ufffd and you\ufffdll never get to that menu. It would be arduous but not impossible\ufffd you\ufffdd restore the whole drive from the original image, then do any upgrades that Yamaha has provided since, and then use the restore function to pull your material from the backup \ufffd and hope it works. I\ufffdve never restored from it, but my only experiences with propriatery backup/restore systems aren\ufffdt great. \ufffdAnyone who remembers MS-DOS\ufffds Backup/Restore will certainly know of what I speak.\ufffd


DKVBrowser lets you copy actual files, but only the non-protected files. A PianoSoft CD that\ufffds been imported to the HD would have to be re-imported.

In bits and pieces, it\ufffdd be possible to rebuild from scratch, providing you\ufffdve been dutifully making backups. It just occurs to me that the right way to do this would be a complete HD image. One snapshot and done.

Can't you use the Mark IV backup function?

There seems to be an emerging trend with respect to SSD failures\ufffd that when they fail, they fail instantly. A mechanical HD would typically start causing problems and throwing out errors, giving you some time (days or weeks) to deal with it. Not so with SSD. A simple Google of \ufffdSSD failure\ufffd will pop up a concerning list of articles.

For those who aren\ufffdt sure what I\ufffdm talking about, you have nothing to worry about\ufffd your piano, if it has a HD, has a mechanical old-school one. For those of us who\ufffdve done an upgrade from mechanical to SSD, this is an issue.

Sidenote: upgrading the HD makes your piano perform wonderfully. Boot times are measured in seconds, not minutes. Jumping around menus goes from annoying to instant. Far more storage space.

The issue that it could die at any moment, though, throws a bit of a snag into things. It\ufffds not so simple to back-up that entire drive. Its contents, sure\ufffd but if my SSD died now, I\ufffdd have to be reverting to the disk image I manually made before I did the upgrade. And I\ufffdd lose any new content that I hadn\ufffdt backed up, and would have to restore it.

So\ufffd\ufffd. suggestions? Anyone know of a good way to backup the piano\ufffds HD without physically removing it and mounting it on an external machine? In a perfect world, DKVBrowser would have an option to [Create HD image] and with one keystroke, you could keep a backup on a computer and simply image a new SSD when needed. Hey Kevin, are you reading this?! :) Is that feasible? Is there a better way? Another way?
