Here's some info on GIGAREC (up to 900MB on a 700MB disc) on supporting Plextor drives:
Test:
-Drives
Plextor: 712A (burn/read)
Liteon DVD ROM: JLMS XJ-JD166S (read)
Samsung CDRW/DVD: SN-324B (read) (aka: piece of shit notebook drive)
-Media
Imation aka: CMC Magnetics (700MB, 79:59,71) 48X
-Data
98:39,11/866MB of mixed media
Results:
-good
fit 866MB on a 700MB disc
copied all files on disc without errors from compatible drives
-bad
had to burn @ 8X
had to read @ ~8X
Samsung drive would not read (not surprising, has hard enough time writing a fooking disc... will probably torture it severely with knives, lighter fluid/matches, and hammer if the occasion presents itself)
probably a big compatibility issue with a lot of older and sub par drives
Conclusion:
quick test, so by no means thorough
won't be using GIGAREC very often, if ever
hell! ain't it handy
