Informations from INQUIRY command: Manufacturer: TSSTcorp, Product: CDDVDW SH-S223Q, Version: SB01 Synchronous data transfer: Not supported Explanation: The INQUIRY command will give fundamental information on a device. First it determines the names of the manufacturer and the product and the product version number (in most cases the version of the firmware). It also determines some infomation on the abilities of the device; the most interesting being whether the device supports"synchronous data transfer". This transfer mode allows a faster transfer of the data through the SCSI-bus. This is also necessary when using "slow" CD-Roms, because the bus will be burdened less. Reading device capabilities: OK Maximum speed: 7056 kByte / second (40.0 times) Cache size: 2048 kByte Read CD-RW: Yes Read Bar code: No Read UPC code: Yes Read ISRC code: Yes Return C2 error pointers: Yes Read R-W subcodes: Yes R-W subcode de-interleaved: Yes Read CD-DA: Yes Read CD-DA correctly: Yes Explanation: All "modern" CD-Roms support a additional command, which can be used by the computer, to determine the capabilities of the CD-Rom. The device supports the command. Feurio! has decoded the most interesting details and output them. It should be pointed out that these are statements by the manufacturer! If a CD-Rom reports that it supports some functions, this doesn't mean that these functions are implemented correctly. Maximum speed: This is the maximum speed, with which the CD-Rom can read audio data. (This has nothing to do with the transfer rate on the SCSI- or IDE-bus.) Cache size: The size of the cache memory of the device. (Feurio! determines the real cache size that can be used by audio data later; in fact there are devices that cannot cache audio data!) Read CD-RW: Here it tells you whether your device can read rewritable media. Read Bar-code: Reports whether your device can read the bar-code which is printed on most CDs/CDRs. Read UPC-code: Report whether the device can read the UPC-code (Universal Product Code) of the CD. Read ISRC-code: Reports whether the device can read the ISRC-code (International Standard Recording Code) of the tracks. Return C2 error pointers: A CD has several methods for error detection and correction. In general, a CD-Rom corrects errors automatically (if possible). There is also a mode, in which the CD-Rom returns, if (and where) there were correctable errors. So it is possible for example to determine, how "good" a CD still is. Unfortunately this mode works only with data CDs! Read R-W-subcodes: Besides the normal audio data, on an audio CD there is some additional data in so-called "Subchannels" on the CD. The individual channels are named with letters. The P- and Q-channels contain e.g. the time-code and the index data. The channels R and W are still not normed, they can be used e.g. for writing the artist and the title of the track to the CD. This parameter reports, if your device can read the R- and W-channels. R-W-subcode de-interleaved: Reports, if the device can read the R-W-channels just in raw format ("No") or in a processed format ("Yes"). Read CD-DA: "Yes" -> The device claims that it can read audio data. Read CD-DA correctly: "Yes" -> The device claims that it can read audio data correctly (i.e. without jitter errors). ===================================================================================================== +++++++++++++++++++++++++ ++ Cache test +++++++++++++++++++++++++ Feurio! will now try to determine the size of the cache memory usable for audio data and the max. transfer rate. To do so, Feurio! will read a certain number of sectors repeatedly and measure the transfer rate. First 1 sector will be read repeatedly, then 2 sectors, and so on. Normally the transfer rate will increase, because the more sectors are read, the fewer search operations will be needed. Number of sectors: 1 (=2 kByte) -> 0.108 MBytes / second Number of sectors: 2 (=4 kByte) -> 0.217 MBytes / second Number of sectors: 3 (=7 kByte) -> 0.322 MBytes / second Number of sectors: 4 (=9 kByte) -> 0.432 MBytes / second Number of sectors: 5 (=11 kByte) -> 0.542 MBytes / second Number of sectors: 6 (=14 kByte) -> 0.647 MBytes / second Number of sectors: 7 (=16 kByte) -> 0.747 MBytes / second Number of sectors: 8 (=18 kByte) -> 0.836 MBytes / second Number of sectors: 9 (=21 kByte) -> 0.731 MBytes / second Number of sectors: 10 (=23 kByte) -> 0.809 MBytes / second Number of sectors: 15 (=35 kByte) -> 1.214 MBytes / second Number of sectors: 22 (=51 kByte) -> 1.427 MBytes / second Number of sectors: 15 (=35 kByte) -> 1.218 MBytes / second Number of sectors: 16 (=37 kByte) -> 1.295 MBytes / second Number of sectors: 17 (=39 kByte) -> 1.107 MBytes / second Number of sectors: 18 (=42 kByte) -> 1.172 MBytes / second Number of sectors: 19 (=44 kByte) -> 1.237 MBytes / second Number of sectors: 20 (=47 kByte) -> 1.302 MBytes / second Number of sectors: 21 (=49 kByte) -> 1.367 MBytes / second Number of sectors: 31 (=72 kByte) -> 1.678 MBytes / second Number of sectors: 46 (=108 kByte) -> 1.867 MBytes / second Number of sectors: 69 (=162 kByte) -> 2.032 MBytes / second Number of sectors: 103 (=242 kByte) -> 2.227 MBytes / second Number of sectors: 154 (=362 kByte) -> 2.383 MBytes / second Number of sectors: 231 (=543 kByte) -> 2.487 MBytes / second Number of sectors: 346 (=813 kByte) -> 2.549 MBytes / second Number of sectors: 519 (=1220 kByte) -> 2.598 MBytes / second Number of sectors: 778 (=1829 kByte) -> 2.645 MBytes / second Number of sectors: 1167 (=2744 kByte) -> 2.686 MBytes / second Number of sectors: 1750 (=4116 kByte) -> 2.701 MBytes / second Number of sectors: 2625 (=6174 kByte) -> 2.729 MBytes / second Number of sectors: 3937 (=9259 kByte) -> 2.754 MBytes / second Number of sectors: 5905 (=13888 kByte) -> 2.791 MBytes / second Number of sectors: 8857 (=20831 kByte) -> 2.829 MBytes / second Number of sectors: 13285 (=31246 kByte) -> 2.881 MBytes / second Number of sectors: 19927 (=46868 kByte) -> 2.945 MBytes / second ------------------------------- Result: Maximum transfer rate: 2945 kBytes/Second Cache size for audio data: 0 kByte It seems that your device isn't able to cache audio data! ############################################ #### FINISHED ############################################
