Well I can't speak for all vendors, espacially ENIX since they were nice enough to invoice me for a copy of the product, but I still haven't recieved it as of yet (I love it :-). Anyway I have 338 meg PRIAM on a 20mhz 386 that was running under AT&T V/386 Release 3.2 with NO problem at all. This drive has 1224 tracks and 15 heads, and I used NO sector re-mapping. The install script liked to rap around after 1024 telling me that the drive only had 198 tracks avalible in fdisk, but in reality it all went fine. I also setup another V/386 Release 3.2 machine with an RLL drive (Adaptec 2372 with NO sector remapping) that had 1156 tracks avalible. This drive exibited the same symptoms as the ESDI install shown above, yet in the end all was OK! I can't speak for all vendors 3.2 product, but so far I have been very plased with the way things are going. I will give a first hand evaluation on ENIX if I ever get any REAL product, which I better see if they want any REAL money!! > Also, the number of bad sectors you reported for your drive is very high, > even for a big ESDI drive.

The PRIAM drive that I recieved had 33 flaws on it, and the 3.2 release had no problems with this. I will assume that that is well below the limit of 3.2 as I haven't run into that brick wall... ------------------------------------------------------------------------------- Internet : howardl@wb3ffv.ampr.org | Howard D.
