I had 250 gb of files on my Seagate wireless plus disk, recognized by Tascam OK. I transferred 50 gb more, from my pc to the disk. I reinserted the disk in the USB contact on the Tascam. Result? The disk was no longer recognized. It came up with Root and Playlist, or just garbled letters "L – L", when I pressed Browse. If I select it the Tascam hangs and must be restarted. I upgraded the firmware from 2.00 to 2.02 but it did not help. I tried a Quick format on the Tascam, but again, no help. I had to do a Full format, which went fairly quickly (20 minutes) this time.
Is the Seagate compatible with the Tascam, used as a music library, for playback? This is the second time the disk has failed, after transferring files from the pc to the disk. It could be semi compatible, and still work OK, if I had known more precisely why things go wrong.
After the full format, I copied ten LP recordings, 38 gb, to the disk (ca 6 minutes, from my pc). The Tascam read the disk (5 minutes) and played the recordings OK. My best guess is: the Tascam stops recognizing the disk (requiring a full format) , if 1) some size limit, maybe 250gb, is reached, and / or 2) too many files are copied in one batch. I don’t think there is any physical disk problem, it seems to be a FAT limit, or how this is implemented in the Tascam. Too much – too many files, whatever - and the whole disk must be reformatted.
I give it a new go, copying 20gb of files. Does Tascam recognize it? Yes, so far, no problem. Another 30gb is copied. Is OK? Yes.
Windows recognizes that the disk is 1.8TB, Tascam thinks it is ca half that size – 860 gb. So it is obvious that some limit is reached, already in the disk info. For now, with 90 gb of files, it plays OK. That is, ca 20 LPs, in double dsd format. Not too bad. But not very convenient, either. Copying 20gb of files and then make the Tascam reread the disk takes me 15 minutes.
This makes me wonder if, even if Tascam can “also” do playback, I should use it only for recording, and then get some trouble-free device able to playback dsd files from my pc hard drive (over ethernet). I use a Squeezebox Touch in that role today – with upgrade so it can do 24 / 96 pcm, and the DSDPlayer plugin. However this outputs dsd downconverted to pcm. The Tascam must use SPDIF input and the recording format must be pcm (not dsd) for it to work. And the sound is notably poorer, more congested and dull, than true dsd from a disk or card connected to the Tascam.
