sorry if this is a double post, i dont think the previoue one went through at all. anyways: my computers drives (pioneer 111d, and samsung shd-162c) were working fine earlier, now they wont recognize anything. device manager has the little exlamation point saying somethings wrong. it claims that the configuration information is missing or wrong. edit--heres what it actually says 'windows cannot start thsi hardware device becuase its configuration information (in the registry) is incomplete or damaged. (code 19).' ive tried to reinstal the driver (1.29) for the 111d, but when it goes to instal it, it says it cand find the device or something like that. ive done a system restore to this morning thinking that owuld help but it didnt. have also unplugged the drives and plugged them back in. so im all out of thoughts. oh yea, im running vista ultimate if that makes any difference. thanks in advance and sorry if this is a double post again. edit again-- found this link but i dont know how to find the devices i need to find, there are a lot of darn options.
