#Low Level Format Needed

I have been searching long and hard for a low level formatting utility. I am using an A3000 and the drive in need or help is a Siemens SCSI drive. Unfortunately, after a crash, I tried to re-write the RDB after changing partition information from the way it was working. The crash had reset my battery backed scsi prefs and set the host adapter to 1 but it wasn't until I messed with the drive that I found out about the battmem settings. Anyway, the problem seems to be that there are bad sectors in the area of the drive where the RDB needs to go. HDToolBox for some reason doesn't seem able to get past and map out the bad sector it first encounters so it just retries all night long! Given the robustness of utilities like RDPrep, I find it hard to believe we don't have a low level format and diagnostic util that can handle bad block mapping and go on. There has to be something out there! Does anyone know of such utility? // \X/ -BiL-

True low level format of a SCSI drive (at least any one made within the last few years) is almost unheard of. They are low-level formatted at the factory. Typically, issuing a low-level format command results in an immediate reply without any real action of formatting. What you DO need is a good way to map out the bad blocks. My ZEUS hard drive setup tools include such a utility, but maybe HDToolBox doesn't. Also you can try IVS TrumpCardPro software which lets you do that, too. If you set up the drive properly on a Zeus or IVS TrumpCardPro the drive will be usable on most controllers which use RDB. Those products (Zeus and TCPro) properly use the RDB and that makes the drives pretty 'universal' after setup or modification with those products. Good luck.

Bill, have you tried to do a Bad Block Remap first? I haven't low-level formatted except in the most extreme of circumstances.

I have tried entering the bad blocks that I have listed from the mfg's sheet, but there must be new ones that need tested to find them. Is this what your are referring to by a "Bad Block Remap" ? // \X/ -BiL-

Bil, it is one of the options in GVP's FaaastPrep. It does seem to be missing in HDPrep. I don't know if it is available in RDPrep, same as with others. If it's available, it should be marked as something like the name I said, either as a button or in a menu.

No, RDPrep has no formatting capability. Does that FaaastPrep let you change the device from gvpscsi.device to plain old scsi.device? Another question for the masses: QBTools has no low level format… Does AmiBack Tools have either a low level or dos level format ability? // \X/ -BiL-

FaaastPrep has low level formatting, as long as you're not using Quantum drives…which won't accept low level formatting. There's no mention of devices in FaaastPrep. Once you've low level formatted it don't matter cause there's nothing on the disk anyway. If you're not using GVP controller, then you'd have to be sure your driver is where it's supposed to be before beginning regular formating (in devices drawer or expansion drawer.

Gary, now you have raised my curiousity. I wonder what my Quantum does for 20 minutes after I give it the low level format command.

Gary, Curious.. So what was GVP FaaastPrep doing when I gave the low level format command to my two Quantum drives? Don't get me wrong, I'm just curious as to what was happening, or if it really did anything.. Trent "If in doubt, empty the magazine"

Trent, same here, especially as it was reeling off cylinder numbers during the process.

Trent, Sorry on the Quantum info…I was quoting from the Fastprep manual and I left out the key word SOME quantums…namely S and LPS series (which I have) don't accept a low level format command. Gary on AutoPilot from Charlotte, NC

OK, FaaastPrep has low level formatting, and bad sector mapping and testing as well, I assume? By devices, I meant can FaaastPrep be used with an A3000 sporting the default scsi.device instead of any GVP specific ones, like gvpscsi.device. Some proprietary prep software will not see devices on the scsi bus unless they are using their own device. Follow? Lastly, if FaaastPrep can indeed be used on devices with scsi.device, where can I get a copy of it? -Bil-

Bil, so far as I know, it only works with GVP controllers.
#137364From: Trent HawkinsMar 28, 1994 10:50 PM
Bil, I think FaaastPrep only works with GVP Scsi controllers that use gvpscsi.device.. You may want to post this question to the GVP Tech (72662,51) in the AmiaVendor forum to see what GVP says. Trent "If in doubt, empty the magazine"

>I think FaaastPrep only works with GVP Scsi controllers that use ??gvpscsi.device.. Right. I have played with it and it doesn't recognize other controllers like the ICD controller on my system. Tom Oklahoma City, OK USA jonest@hfsi.com
