Greetings, As I said in my last post, dmraid was working well, detecting all the partitions on the two-disk striped set (Promise Fastrack). The set contained a primary windows partition, and an extended windows partition, with about 11 GB unallocated. I start fdisk with /dev/mapper/pdc_djbcgacc as the argument. I created a new primary partition and set the type to Linux. I issued a 'write' and quit fdisk. I then rebooted. Since then, things are messed up. I'm getting alot of these: end_request: I/O error, dev hde, sector 579 end_request: I/O error, dev hde, sector 580 end_request: I/O error, dev hde, sector 581 end_request: I/O error, dev hde, sector 582 end_request: I/O error, dev hde, sector 0 ... When I run dmraid -ay, I get this: ERROR: hpt37x: reading /dev/hde[Input/output error] ERROR: hpt45x: reading /dev/hde[Input/output error] ERROR: isw: reading /dev/hde[Input/output error] ERROR: lsi: reading /dev/hde[Input/output error] ERROR: nvidia: reading /dev/hde[Input/output error] ERROR: pdc: reading /dev/hde[Input/output error] ERROR: pdc: reading /dev/hde[Input/output error] ERROR: pdc: reading /dev/hde[Input/output error] ERROR: pdc: reading /dev/hde[Input/output error] ERROR: pdc: reading /dev/hde[Input/output error] ERROR: sil: reading /dev/hde[Input/output error] ERROR: via: reading /dev/hde[Input/output error] pdc_djbcgacc does show up in /dev/mapper, but none of the partitions do. Starting fdisk shows no partitions. Basically, the system is having trouble with hde, which is the first of two disks in my striped set. I can boot to windows off this same set with no problem. Veritas disk manager sees the partitions no problem. Note: if I do a warm reboot, the system hangs at the IDE detection stage. I have to power cycle the box for the Promise drive scan to succeed. So something bad has definitely happened. Does anyone have any insight to offer? Thanks!
