First of all, I'd like to thank anybody who answered my question on window refreshing. I tried responding personally to those people, but all of my mail bounced... Anyway, I know this has been asked a billion times, but I'm going to ask it again. I would like to a buy a relatively cheap h.d. for my 2000 (Under 700, hopefully) that will support the new fast file sytem. Could anybody please e-mail me some suggestions? Thanks. BTW, has anybody tried Pacific Perifrials SCSI interface? It retails for $249, and is alot cheaper than the CBM alternative. Alexander Hinds BITNET:A_HINDS@HVRFORD USENET:ahinds@hvrford

Can somebody tell me how many HDisks the A2090 can support? Also what are some cheap prices on SCSI compatible 50 meg harddrives? Thanx in advance. backstro@silver.bacs.indiana.edu

Well you purchased the a2090 instead of the pacific peripherals card I have used both and a few facts are in order 1) Pacific Peripherals card allows each and every partition to be FFS format, A2090 does not. 2) Pacific peripherals card will auto boot with ROM revision A2090 will not to my knowledge 3) Diskperf with the Old File system showed Pac Peripheral card to be faster. 4) The A2090 card held the reset line low on power up until a BindDrivers call was made resulting is slight compatibility problems for some SCSI disks (eg had to warm boot them since the drives would not spin up until reset line went high) Based on my experience I would recomend the pacific peripherals board but it has 2 major drawbacks 1) When doing large block xfers it raises the interrupt level to like 5 or 6 for long periods of time resulting in lock out of serial port and keyboard devices. This will be fixed soon they say by a slightly slower device driver that does not have this problem. 2) It will only support SCSI drives so even though you save $$ on the Controller you may not save $$ in the long run. In the end you must decide, if it were me right now I would probably wait and see what the HardFrame Card from Microbotics will look like. -Roger

Note that the ST506 drives cannot have more than 8 heads due to some firmware limitations on the card. As for prices, the price of an imbedded SCSI drive is currently about $11 to $12 per Megabyte for fast drives (< 30 Msec). Less for slower drives (>= 40 Msec). So for a 50 meg drive you can expect to be charged somewhere between 500 and 600 dollars depending on how fast it is. Note that if you buy Seagate drives they have a slow and a fast version (usually indicated by -0 (slow) or -1 (fast) after the model number) --Chuck McManis uucp: {anywhere}!sun!cmcmanis BIX: cmcmanis ARPAnet: cmcmanis@sun.com These opinions are my own and no one elses, but you knew that didn't you.

Afraid that's wrong. If you set up a SCSI disk as unit 0, then it automounts the first partition of the drive. If you set it up as SCSI unit 1 or higher, it doesn't automount, so you can use FFS on the whole disk. For st506 disks, you are right, however. >3) Diskperf with the Old File system showed Pac Peripheral card to > be faster. What conditions? In particular, same drive, exact same files on the drives, and in the same places (i.e. unfragmented at start of test, with the same amount of data)?

It's been noted that the 48Meg SCSI ST157N goes for ~$450-$475. That might only be the 40ms version, or might not be. There's also the ST277N, 40ms, 65meg, which sells for ~$550-600. // Randell Jesup Lunge Software Development // Dedicated Amiga Programmer 13 Frear Ave, Troy, NY 12180 \\// beowulf!lunge!jesup@steinmetz.UUCP (518) 272-2942 \/ (uunet!steinmetz!beowulf!lunge!jesup) BIX: rjesup (-: The Few, The Proud, The Architects of the RPM40 40MIPS CMOS Micro :-)
