What is the Cylinder count and # of surfaces on a Quantum 240LPS Prodrive. It was formatted on an old GVP Controller without Fastprep. The capacity is 240Meg Or what is a tech number for Quantum. Thanks, Jeff Lander

Hello Phil, Why do you need the specs? If it is a SCSI drive, it should know it's specs for itself! Quantum LPS 240 AT: Log. Cylinders: 723 Log. Heads: 13 Log. Sectors/Track: 51 Write Pre-comp.: 0 Landing Zone: 723 Sectors per drive: 479,349 Juergen (via Autopilot from Germany)

The FastPrep readings say that the disk has 0MB and it does not recognize it as a Read/Write drive. It may be trash. Thanks for the help. Jeff

Phil: Here's the stats for my 240 LPS, as reported by ExpertPrep: Lo Cyl: 1 Hi Cyl: 2662 Heads: 4 Sectors: 65 Formatted Size: 234 MB Blocks: 479350 Buffer Memory: 32 DMA Mask: 0xFFFFFFFE Max Transfer: 0x7FFFFFFF I'd suggest using ExpertPrep and use the following commands: UnPrep Hard Drive Low Level Format You should then be able to page thru the text field to add your partition name(s) etc. Then use: Write This Setup folllowed by AmigaDos Format Unles there's a fault in the drive (you can also try a Bad-Block ReMap) this should get you up and running with a fresh drive. All of this ASSUMING you've given up trying to save any data on the drive. ***The above noted procedure will DESTROY ALL DATA on the hard drive*** The program will warn you as well. Hope this helps!

Phil, The numbers are arbitrary. It is calculated by FastPrep when it reads the firmware and can change with each read of the drive. If you cannot get the drive to appear and need to get information off of it, I recommend that you get AMI-BACK TOOLS, which has a facility for searching a drive for partitions and creating mountlists to allow them to mount manually. YOu can then retrieve your info and re-prep later, trying the values set by AMI-BACK TOOLS. GVP TECH

Thanks, tried it no such luck. A SCSI ID search comes back with no drives available. I thinks it's a gonner. Jeff
