Since my mid-2006 scale stock was now exhausted, I lay me - due to the many negative reviews but as a precaution - only a 50-pack Spindle for test purposes.
My more than sobering realization:
42 1. Of the 50 blanks were not writable (on which 4 different types of burners), that the burn process has meanwhile canceled.
7 2. Of the 8 described blanks were either not or only the directory structure to be read. On the data itself no longer has access was possible
3. Only a burned DVD was subsequently also readable again
Conclusion:
------
Pure garbage for cheap 12.00 EUR. If I highly expect me, cost me 50 OPERATING DVD's 50 x 12.00 EUR = 600.00 EUR!
Luckily I had for testing purposes as well - and as an alternative - bought a 50-pack Spindle Verbatim blanks for about 15.00 EUR. These blanks I had no problems!
This one star I forgive for Ricoh blanks is a gift, because there is unfortunately no negative star for rating!
