I was scanning a multi-page document via Acrobat, using a WIA-HP ScanJet 5300C, USB scanner, when I was distracted and left the scanning half way through for some time. When I returned, the scanning dialogue had disappeared, with the pages already scanned showing in the Acrobat window. There was some message (presumably an error) showing on the screen, but I accidentally clicked off on it, before I read it. Anyway, I picked up with the scanning where I had left off, and the whole scan completed successfully.
However, when I went to save the file, which had been created, to the D: drive, there was no D: drive listed in the 'save' dialogue. I then tried to open a different file, but again, there was no D: drive in the 'open' dialogue.
I subsequently went to My Computer, and there, where the D: drive should have been in the window, was the scanner, and indeed, clicking on it, took me to the scanner interface. There was also an E: drive missing, which had always previously shown, but that drive is for another OS on the dual boot system.
Both D: and E: drives show up as healthy under Computer Management. From a command prompt, I can get up a DIR of D: and all sub-directories. D: is basically data, but also some programs. I can execute a program on D: from the command line, and I can load and save documents by entering the full path in the appropriate dialogue. I can't search from the graphical interface, because it does not show D:
Using RegEdit, I have restored the registry values to a point just before this happened, but to no avail.
Can someone please tell me how to fix this.
Thanks in advance-
