Informations from INQUIRY command:
Manufacturer: SATA, Product: TSSTcorpCDDVDW S, Version: SB03
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: 2823 kByte / second (16.0 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) -> 0.042 MBytes / second
Number of sectors: 2 (=4 kByte) -> 0.084 MBytes / second
Number of sectors: 3 (=7 kByte) -> 0.127 MBytes / second
Number of sectors: 4 (=9 kByte) -> 0.169 MBytes / second
Number of sectors: 5 (=11 kByte) -> 0.210 MBytes / second
Number of sectors: 6 (=14 kByte) -> 0.253 MBytes / second
Number of sectors: 7 (=16 kByte) -> 0.296 MBytes / second
Number of sectors: 8 (=18 kByte) -> 0.336 MBytes / second
Number of sectors: 9 (=21 kByte) -> 0.285 MBytes / second
Number of sectors: 10 (=23 kByte) -> 0.317 MBytes / second
Number of sectors: 15 (=35 kByte) -> 0.476 MBytes / second
Number of sectors: 22 (=51 kByte) -> 0.558 MBytes / second
Number of sectors: 15 (=35 kByte) -> 0.474 MBytes / second
Number of sectors: 16 (=37 kByte) -> 0.508 MBytes / second

Number of sectors: 19 (=44 kByte) -> 0.482 MBytes / second
Number of sectors: 20 (=47 kByte) -> 0.507 MBytes / second
Number of sectors: 21 (=49 kByte) -> 0.532 MBytes / second
Number of sectors: 31 (=72 kByte) -> 0.653 MBytes / second
Number of sectors: 46 (=108 kByte) -> 0.727 MBytes / second
Number of sectors: 69 (=162 kByte) -> 0.795 MBytes / second
Number of sectors: 103 (=242 kByte) -> 0.871 MBytes / second
Number of sectors: 154 (=362 kByte) -> 0.927 MBytes / second
Number of sectors: 231 (=543 kByte) -> 0.976 MBytes / second
Number of sectors: 346 (=813 kByte) -> 0.997 MBytes / second

-------------------------------
Result:
Maximum transfer rate: 1152 kBytes/Second
Cache size for audio data: 0 kByte
It seems that your device isn't able to cache audio data!
