HP Pavilion Slimline s5503w will not load. Replaced CMOS battery & now, all I can get is DOS or Cmd Prompt


If you mean a flat 'blinking' Cursor at the top-left of the Display.....then the load process did not complete; it halted at the partition table which could not be found.

some causes of this : In order of likely-hood

Invalid Boot Sector (it is pointing to the wrong place,)
(if you have Win7 or 8, startup repair will usually fix this.)

Bad Read-Head on the Hard drive causing errors (must replace hard drive.)

Virus.

How To Recover Lost, Deleted Or Missing Files And Partitions


1. If TestDisk is not yet installed, it can be downloaded from <a href="http://www.cgsecurity.org/wiki/TestDisk_Download">TestDisk Download</a>. Extract the files from the archive including the sub-directories.<br /><br />2. To recover a lost partition or repair the filesystem from a hard disk, USB key, Smart Card, etc., you need enough rights to access a physical device. <ul> <li> <img src="dos.png" /> Under DOS, run TestDisk.exe </li> <li> <img src="win.png" /> Under Windows, start TestDisk (ie testdisk-6.9/win/testdisk_win.exe) from an account in the Administrator group. Under Vista, right-click testdisk_win.exe and then "Run as administrator" to launch TestDisk. </li> <li> <img src="linux.png" /> Under Unix/Linux/BSD, you need to be root to run TestDisk (ie. sudo testdisk-6.9/linux/testdisk_static) </li> <li> <img src="macosx.png" /> Under MacOSX, if you are not root, TestDisk (ie testdisk-6.9/darwin/TestDisk) will restart itself using sudo after confirmation on your part. </li> <li> <img src="os2.png" /> Under OS/2, TestDisk doesn't handle a physical device, only a disk image. Sorry. </li></ul> 3. To recover partition from a media image or repair a filesystem image, run: <br /> <ul> <li> testdisk image.dd to create a raw disk image </li> <li> testdisk image.E01 to recover files from an Encase EWF image </li> <li> testdisk 'image.???' if the Encase image is split into several files. </li></ul> 4. <img src="linux.png" /> <img src="macosx.png" /> To repair a filesystem not listed by TestDisk, run testdisk device, i.e. <br /> <ul> <li> testdisk /dev/mapper/truecrypt0 or testdisk /dev/loop0 to repair the NTFS or FAT32 boot sector files from a TrueCrypt partition. The same method works with filesystem encrypted with cryptsetup/dm-crypt/LUKS. </li> <li> testdisk /dev/md0 to repair a filesystem on top of a Linux RAID device. </li></ul>5. Choose Create to instruct Testdisk to create a <a href="http://www.cgsecurity.org/wiki/Log_file">log file</a> containing technical information and messages, unless you have a reason to append data to the <a href="http://www.cgsecurity.org/wiki/Log_file">log</a> or you execute TestDisk from read only media and must create the <a href="http://www.cgsecurity.org/wiki/Log_file">log</a> elsewhere.<br /><br />6. Choose None if you do not want messages and details of the process to be written into a <a href="http://www.cgsecurity.org/wiki/Log_file">log file</a> (useful if for example Testdisk was started from a read-only location).<br /><br />7. Press Enter to proceed.<br /><br />8. All hard drives should be detected and listed with the correct size by TestDisk:<br /><img src="moz-screenshot.png" /><img src="pctech1.gif" /><br /> <ul> <li> Use up/down arrow keys to select your hard drive with the lost partition/s. </li> <li> Press Enter to Proceed. </li></ul> <img src="macosx.png" /> If available, use raw device /dev/rdisk* instead of /dev/disk* for faster data transfer. <br /><br />9. TestDisk displays the partition table types: <span><img src="Partition_table_type.gif" /></span> <ul> <li> Select the partition table type - usually the default value is the correct one as TestDisk auto-detects the partition table type. </li> <li> Press Enter to Proceed. </li></ul><br />10. TestDisk displays the menus:<br /> <span><img src="Menus.gif" /></span> <ul> <li> Use the default menu "Analyse" to check your current partition structure and search for lost partitions. </li> <li> Confirm at Analyse with Enter to proceed. </li></ul> 11. Now, your current partition structure is listed. Examine your current partition structure for missing partitions and errors: <br /> <span><img src="Analyse.gif" /></span> <ul> <li>The first partition is listed twice which points to a corrupted partition or an invalid partition table entry.</li> <li>Invalid NTFS boot points to a faulty NTFS boot sector, so it's a corrupted filesystem.</li> <li>Only one logical partition (label Partition 2) is available in the extended partition. One logical partition is missing.</li></ul>12. Confirm at <i><b>Quick Search</b></i> to proceed. <span><img src="Vista_check.gif" /></span> <ul> <li> Confirm according to your OS and created partitions to proceed. </li></ul>13. During the <i><b>Quick Search</b></i>, TestDisk has found two partitions including the missing logical partition labeled <i><b>Partition 3</b></i>. <a href="http://www.cgsecurity.org/wiki/File:First_results.gif"><img src="First_results.gif" /></a> <ul> <li> Highlight this partition and press <i><b>p</b></i> to list your files (to go back to the previous display, press q to Quit).</li> <li>If all directories and data are correctly listed, Press Enter to proceed. </li></ul> 14. Save the partition table or search for more partitions?<br /> <span><img src="Search_menu.gif" /></span> <ul> <li> <i><b>When all partitions are available</b></i> and data correctly listed, you should go to the menu <b>Write</b> to save the partition structure. The menu Extd Part gives you the opportunity to decide if the extended partition will use all available disk space or only the required (minimal) space. </li> <li> <i><b>If you are still missing a partition</b></i>, highlight the menu <i><b>Deeper Search</b></i> (if not done automatically already) and press Enter to proceed. </li></ul>

Invalid partition table


This means that the operating system has crashed.. You can try to insert the operating system's disk and you can repair the operating system.

This happens when some file are missing which are essential for the system start up.

Could you please inform me about the operating system that you previously had? It would be easier for me to help you.

Thanks

How to connect iomega ego blackbelt 3.0 to mack and change the partition


Mac decided not to go with USB 3.0 so you will have to use the USB 2.0 Y cable.
Using the USB Y cable. Plug the cable into the device first, then make sure to plug both USB's in to the computer starting with the short side USB then the longer side USB second. Also try using the USB's on the back side of the computer.
Formatting with Mac OS X, version 10.5 or above. 1. Make sure you have copied any needed files to another location. 2. Select Applications > Utilities > Disk Utility 3. In the left hand column, click on the drive icon for the Iomega Hard Drive. Make sure you click on the high level icon, not the second level volume icon. 4. Select the Partition tab. 5. Change Volume Scheme from Current to 1 Partition. 6. Select the format type from the Format drop-down menu. Select Mac OS Extended (Journaled) (recommended) or Mac OS Extended. 7. Click on the Options button. 8. Select the type of partition you want to use: GUID Partition Table - for boot ability on Intel-based Macs Apple Partition Map - for boot ability on PowerPC-based Macs Master Boot Record - if you will use the drive on a PC as well as your Mac. Use this option ONLY if you selected PC-DOS as the format type. CAUTION! In most cases, the computer will fail to format the drive as a Mac OS Extended (HFS+) partition using Master Boot Record. For best results, always choose GUID Partition Table (Intel) or Apple Partition Map (PowerPC). 9. Click OK. 10. Click Apply (10.5-10.6) or Partition (10.4). The drive is ready to use when the format completes.

Wont boot up,black screen.message on screen says,invalid partitio

  • Enter: Y
  • Now to check for active partition, enter: 2

PLace the Sansa in Recovery Mode, plug in, and see that the 16MB FORMAT icon appears in Windows Explorer.

Right click in the window, and create a new folder named sansa.fmt

DO NOT ATTEMPT TO FORMAT THE RESERVED PARTITION USING THE WINDOWS FORMAT COMMAND!!

Drag and drop the sansa.fmt folder into the 16MB FORMAT partition. Right-click and select eject.

Unplug, and see if it will automatically format.
